With increasing deaths and the number of infected individuals, coronavirus has left the worlds economy dwindling. This calls for busting myths of coronavirus, food and imported goods from China.

Several experts stated that there is no chance that virus could be transmitted from touching any surface of packaged shipped product. Further, they declared that no type of active delectable virus could travel via surface. David Evans, a professor in the Department of Medical Microbiology and Immunology at the University of Alberta states that coronavirus has a lipid bilayer a fatty membrane. Also, it is fragile and damaged easily. If it disperses on a surface, it dries and gets inactive stuck on that surface. However, the myths of coronavirus spread faster than the actuality.

India imported raw and powdered garlic from China in huge quantities. However, the coronavirus fears have stopped the supply of Chinese garlic, which were in great demand until now. Despite its toxicity levels due to bleaching, people prefer to use it over Indian variety because of its easiness to peel. However, the news of coronavirus outbreak has vanished Chinese garlic from the markets.

Ongoing myth about spreading of coronavirus by consuming chinese garlic is false. The conflicting misinformation out there resulted in digital platforms tightening the noose. Further, platforms like Twitter, Google and Instagram have started redirecting users to their home countries health authorities.

The widespread circulation of myths regarding the Coronavirus (Covid-19) has resulted in decreasing sales of chicken and meat. Citing this, the Poultry Farm Association organized chicken mela in Uttar Pradesh where it provided cooked chicken meals at a very low cost. Also, the top chicken companies have declared on their social media handles that properly cooked meat is safe for consumption.

The increasing myths of coronavirus are making people careless towards the threat. Also, the rumors about homeopathic medicines preventing the virus have spread. So, to clear out the doubts, the Ministry of AYUSH has issued an advisory that there is no medicine to prevent the coronavirus. Hence, people must take precautions rather than popping pills to boost their immunity. People have fallen prey to the misinformation on social media platforms. Thus, people need to identify the source of information before taking action.

In conclusion, Washing hands, wearing masks in public, staying away from public events and keeping distance from sick people is the right approach.

Children with a rare food allergy have higher chance of being diagnosed with other allergies – The Medical News

March 7, 2020 medical

Researchers at Children's Hospital of Philadelphia (CHOP) have found that children with a rare food allergy known as food protein-induced enterocolitis syndrome, or FPIES, have a significantly higher chance of being diagnosed with other allergic conditions, including eczema, traditional food allergy and asthma. But the researchers also found that FPIES did not directly cause those other allergies.

The study was published in the March issue of The Journal of Allergy and Clinical Immunology: In Practice.

"This work refines our view of the natural history of FPIES and expands our understanding of the relationship between this condition and other allergic diseases," said first author Melanie Ruffner, M.D., Ph.D., attending physician in the Division of Allergy and Immunology and the Center for Pediatric Eosinophilic Disorders at CHOP. "It's important for clinicians to keep in mind that patients with FPIES have a higher frequency of allergic manifestations and therefore provide appropriate screening and care as needed."

FPIES causes repetitive vomiting, diarrhea, and lethargy several hours after eating a trigger food, frequently cow's milk, soy, and grains. The condition typically develops during infancy, though it can occasionally occur in older children and adults.

Although previous research has collectively shown patients with FPIES have increased rates of eczema, other food allergies and asthma - so-called atopic allergies - researchers have not investigated the association between FPIES and other allergies to look for a potential causal link.

To do so, Ruffner and her collaborators looked at a cohort of more than 150,000 pediatric patients, of which 214 had FPIES. The investigators compared the rate of atopic allergies in FPIES patients to those without FPIES. They also followed the patients over time to see if there were differences in the timing of when FPIES patients developed atopic allergies compared to other patients.

The authors found that those with FPIES had substantially higher allergy rates than patients without the condition. FPIES patients were diagnosed with traditional food allergy at about six times the rate of those without FPIES and with atopic dermatitis at about twice the rate. There was a slightly smaller increase in the rate of asthma diagnoses, but those with FPIES were still diagnosed at a higher rate than those without the disease.

However, when the research team looked at the timing of the development of allergies, and whether a diagnosis of FPIES would lead to atopic allergies later in life, they did not find a causal link between the two. Thus, unlike the so-called atopic march - the progression of atopic disorders from eczema in infants to hay fever, food allergy and asthma in older children - FPIES does not cause other allergic disorders but instead is associated with them.

Although there is an increased rate of atopic allergies in patients with FPIES, our analyses demonstrate that a prior diagnosis of FPIES does not increase the rate of atopic allergies later in life. This pattern of association supports a yet-unknown cause, such as a shared predisposition to both types of allergy."

Clinical teams ready; research for vaccines, drugs underway

Postdoctoral researchers Brett Case, PhD, (left) and Adam Bailey, MD, PhD, wear full personal protective equipment to study the COVID-19 virus. Washington University School of Medicine in St. Louis physicians and researchers are preparing for COVID-19 cases and working on drugs and vaccines to fight the disease.

Soon after a novel coronavirus first appeared in China in late 2019, researchers, doctors and staff at Washington University School of Medicine in St. Louis began preparing for the possibility of an outbreak. Infectious disease physicians started planning how to respond if a person with suspected exposure to the virus arrived on campus, and researchers set to work finding drugs or vaccines to treat or prevent COVID-19, the name given to the illness caused by the virus.

New infectious diseases emerge every so often, and we have to be vigilant, said Steven J. Lawrence, MD, an associate professor of medicine. Over the last few decades weve had HIV, Ebola, SARS, Zika and now COVID-19. Such diseases usually arise when an animal virus manages to jump into people because of close contact between people and animals. The chance of preventing that happening anywhere in the world is probably zero. What we can do is be prepared to respond as rapidly as possible when it happens.

In December, China reported the first cases of a mysterious illness characterized by fever, a dry cough and difficulty breathing. Within weeks, Chinese scientists had identified the cause as a never-before-seen member of the coronavirus family. Coronaviruses typically cause mild infections such as the common cold. But in 2002, a newly emerged strain of coronavirus caused an outbreak of severe acute respiratory syndrome (SARS) that killed nearly 1,000 people before it was contained.

It quickly became evident that the 2019 coronavirus strain, named SARS-CoV-2, was more like SARS than the common cold. By late January, tens of thousands of people in China were infected. At the time, the only cases in the U.S. were believed to be in people who had been infected while traveling in China.

In January and February, we had a brief moment of opportunity to contain this outbreak in the U.S. by knowing where people had traveled, Lawrence said. Thats why the efforts to identify and isolate people with the virus were so robust, even though we had such few cases. Once the virus started spreading from person to person in the U.S., it became much, much more complicated.

Washington University infectious disease physicians (from left) Stephen Y. Liang, MD, Steven J. Lawrence, MD, Hilary M. Babcock, MD, and David K. Warren, MD, are preparing for the possibility of COVID-19 cases in St. Louis. Pictured is the team, in 2014, discussing emerging infectious diseases.

Hilary M. Babcock, MD, a professor of medicine and medical director of the Infection Prevention and Epidemiology Consortium for BJC HealthCare, and David K. Warren, MD, a professor of medicine and the medical director for infection prevention at Barnes-Jewish Hospital, did not wait for the virus to start spreading in the U.S. In January, they established a virtual incident command center at BJCHealthCare and called twice-weekly meetings to develop a coronavirus outbreak response plan for all BJC hospitals, including hospitals and clinics staffed by Washington University physicians. The team started by dusting off a plan developed in 2002 for SARS and adapting it to COVID-19 as more information emerged.

The data on mortality for COVID-19 remains a moving target and continues to be assessed. So far, people who are older and those with underlying health conditions, such as heart disease, lung disease or with compromised immune systems, have a higher risk of death. Early data suggests that the illness is more deadly than seasonal flu. Like SARS and the flu, COVID-19 spreads easily through droplets released when infected people cough or sneeze. The viruss contagiousness means that proper use of personal protective equipment is crucial to protect health professionals caring for coronavirus patients.

Communication is one of the most important tools at a time like this, Babcock said. We needed to make sure that our front-line clinicians can very quickly recognize that someone might be infected, and that they know what to do if a potentially infected person presents at their clinic. We also developed guidance regarding which personal protective equipment to wear when working with a patient suspected of having COVID-19 mask, gloves, eye shield, respiratory equipment, and gown how to put it on so it is most effective, and, most importantly, how to take it off without contaminating yourself.

Babcock and Warren also are keeping a close watch on outbreaks in other countries and implemented new travel screening recommendations across the university as the virus has spread to other countries, notably South Korea, Italy and Iran.

We are ready, Babcock said. Weve been ready for weeks. Its only a matter of time before we get our first case.

Building the toolkit to fight COVID-19

Across campus, a team led by Sean Whelan, PhD, the Marvin A. Brennecke Distinguished Professor and head of the Department of Molecular Microbiology, and Michael S. Diamond, MD, PhD, the Herbert S. Gasser Professor of Medicine, is looking for ways to treat COVID-19 or reduce its spread.

We had a discussion in early January and decided then to work on advancing therapeutics and vaccines for coronavirus, because it had the potential to be a significant problem, said Whelan, who took over as head of the molecular microbiology department on Jan. 1. It is our responsibility as part of the biomedical research community to do this. The consequences of this virus in places where there isnt a good health-care system could be dire.

Whelan called weekly meetings to coordinate the School of Medicine coronavirus research effort. He and Diamond have special expertise in emerging viral infections. Diamond led the School of Medicine response to Zika virus, during which he and others developed a mouse model of Zika infection and identified an antibody that is now used as part of a diagnostic test. While on the faculty at Harvard, Whelan studied Ebola and identified a critical protein that the virus exploits to cause deadly infections.

Whelan and Diamond built a research team including influenza experts Jacco Boon, PhD, an associate professor of medicine, and Ali Ellebedy, PhD, an assistant professor of pathology and immunology, who provided advice and scientific tools for studying respiratory viruses; structural immunologist Daved Fremont, PhD, a professor of pathology and immunology, who has begun studying the interactions of coronavirus proteins with antibodies and other human proteins to facilitate vaccine design and improved diagnostics; David T. Curiel, MD, PhD, the Distinguished Professor of Radiation Oncology,who began designing a potential vaccine; and Siyuan Ding, PhD, an assistant professor of molecular microbiology, who is investigating whether the virus also can be transmitted through the fecal-oral route.

The team is analyzing the structure of the viruss proteins to find possible targets for drugs or vaccines, looking for antibodies that might protect against disease, creating potential vaccines using multiple strategies, and developing a mouse model that can be used to test potential drugs and vaccines.

In addition, geneticist Ting Wang, PhD, the Sanford and Karen Loewentheil Distinguished Professor of Medicine, and members of his lab built a genome browser to help researchers study the genetics of the COVID-19 virus and compare different strains. Greg Bowman, PhD, an associate professor of biochemistry and molecular biophysics whose work focuses on how proteins take their shape, has mobilized his crowdsourced Folding@home Consortium to find the shape of coronavirus proteins to inform drug and vaccine development.

The speed of research on coronavirus has been extraordinary, Diamond said. Chinese scientists identified the virus, sequenced its genome, identified the probable animal source, and released the genomic sequence to the public in a matter of weeks. Groups around the world have been creating and sharing the tools we need to interrogate this virus. But even so, these things take time. Every day, the U.S. is seeing new cases. We are racing against the clock.

Washington University School of Medicines 1,500 faculty physicians also are the medical staff of Barnes-Jewish and St. Louis Childrens hospitals. The School of Medicine is a leader in medical research, teaching and patient care, ranking among the top 10 medical schools in the nation by U.S. News & World Report. Through its affiliations with Barnes-Jewish and St. Louis Childrens hospitals, the School of Medicine is linked to BJC HealthCare.

Allergan and AbbVie Turn Eyes to the FTC for Approval of their $63 Billion Merger – BioSpace

March 5, 2020 medical

AbbVie and Allergan have cleared a major hurdle in completing the merger of the two companies that began in June of 2019. On Tuesday, the European Commission gave the green light to the merger following the divestiture of an investigational autoimmune treatment.

With the nod from the European Commission, all eyes are now on the U.S. Federal Trade Commission as it continues to review the pending merger. The FTC does not have a set timeline, but AbbVie and Allergan said they have a timing agreement with the agency that could result in a decision early in the second quarter of this year. AbbVie and Allergan said they continue to fully cooperate with the FTC during its review and intend to close the transaction at the earliest possible date.

The European Commissions approval of the $63 billion merger was contingent on the divestiture of brazikumab, an investigational IL-23 inhibitor in development for autoimmune diseases, to AstraZeneca. In January, AbbVie and Allergan announced their intentions to divest some assets in order to avoid regulator concerns over a monopoly. In addition to the deal with AstraZeneca for brazikumab, which is currently in Phase IIb/II development for Crohn's Disease and in Phase II development for ulcerative colitis, the companies sold the approved Zenpep (pancrelipase), a treatment for exocrine pancreatic insufficiency due to cystic fibrosis and other conditions, and Viokace, a pancreatic enzyme preparation, to Nestle.

With clearance from the European Commission, share prices for both companies are climbing this morning. AbbVie is up 3.57% to $90.70 per share as of 10:27 a.m. and Allergan is up % to $194.74 per share, as of 10:27 a.m.

While the news is positive for investors, particularly after a tumultuous week in the stock market, some consumer groups have been trying to stop the merger of AbbVie and Allergan. The groups opposed to the merger of the companies have raised concerns over the creation of a monopoly that will stifle competition in the immunology market. The organizations, which includes American Federation of State, County, & Municipal Employees, Public Citizen, Service Employees International Union, Doctors for America and Prescription Justice, argue that even with the divestiture of brazikumab, AbbVie dominates the immunology market through a variety of exclusionary tactics to hamper rivals.

In a letter sent to the Federal Trade Commission, the group said even with the divestiture to AstraZeneca, there is a chance that drug will not increase competition in the market since its still an investigational medication.

In January, AbbVie and Allergan announced plans for a new, stand-alone company called Allergan Aesthetics that will include Allergans blockbuster aesthetics treatment Botox as a tent pole.

Vir Biotechnology and Alnylam Join the Fight Against COVID-19 – Motley Fool

March 5, 2020 medical

Yet another biotech has joined the fray against the novel coronavirus: Alnylam Pharmaceuticals (NASDAQ:ALNY) andVir Biotechnology (NASDAQ:VIR) on Wednesday announced they were expanding their ongoing collaboration to include an attempt to develop RNA interference (RNAi) treatments for SARS-CoV-2.

According to the American Society for Microbiology, coronaviruses are everywhere. They are the second-leading cause of the common cold, after rhinoviruses. In an article on the society's website, Dr. Rodney Rhode wrote, "Coronaviruses ... mutate and change at a high rate, which can create havoc for both diagnostic detection as well as therapy (and vaccine) regimens."

Image source: Getty Images

The two companies have been collaborating since the 2017 founding of Vir, which specializes in using immunology to fight and prevent infectious diseases. Vir CEO George Scangos was the CEO ofBiogenbefore he took control of the start-up.

"Given the scope and speed of the COVID-19 outbreak," Scangos said, "Vir is seeking multiple approaches that combine our expertise in infectious disease with that of current and new partners to respond rapidly. Alnylam has been an excellent partner, and our complementary capabilities made this a compelling opportunity..."

As Alnylam CEO John Maraganore said, "We believe RNAi therapeutics represent a promising approach for targeting coronaviruses, like SARS-CoV-2. As the leader in RNAi therapeutics, we at Alnylam are committed to doing our part in joining other biopharmaceutical companies, like Vir, to address this emerging outbreak."

Vir will lead all development and commercialization of any selected drug molecules. Alnylam retains the option to share in the profits and losses associated with the effort. Shares of Vir were up 14% in early trading Wednesday, while Alnylam was up 3%.

Dr. David Gottsegen: Coronavirus and the dangers of a president with no concern for science – GazetteNET

March 5, 2020 medical

Last week in my office, I had the first case where I questioned whether a patient could have Covid-19, or coronavirus.

The young person had traveled abroad and returned with flu-like symptoms. I discovered that it is not easy for physicians to make this diagnosis. I first called Baystate Medical Center and was directed to the Department of Public Health in Boston, where a person took my number; an epidemiologist called me back. The epidemiologist told me that this patient was low risk and did not require testing.

If she had, then I would have had to fill out a 17-page questionnaire, which changes daily, then collect a nasal and oral viral swab, and send it to Baystate, where, once a day, a courier brings them to Boston for testing, where until this week, it would be then sent to the Centers for Disease Control and Prevention in Maryland.

Many people I speak with, including other doctors, are not aware of this process, thinking that there are special collection kits out there. The collection requires only an ordinary viral culture, but the process is very special.

Adding to the confusion is that President Donald Trump has said that all information about Covid-19 would come from Vice President Mike Pence, not health experts within the administration.

Hes used his bully pulpit to take aim at Democrats for creating a hoax around this new epidemic, even as public health experts like Anthony Fauci, director of the National Institute of Allergy and Immunology, said that the new coronavirus has adapted very well to humans and seems now to lead to a higher mortality rate than influenza.

In addition, budget cuts by the Trump administration have severely hampered the public health communitys efforts to protect American people from the novel coronavirus and other exotic infections. There has been controversy about his proposed reduction in funding to the CDC, since many of the cuts were not supported by Congress.

But this much is well documented: Trump eliminated the position of senior director for global health security and biodefense in the National Security Council, established after the first Ebola virus outbreak. He terminated epidemic prevention efforts in 39 out of 49 countries, including the Congo and China.

The Obama administration maintained a tiered epidemic response approach, created after the 2014-2016 Ebola epidemic, with 10 advanced facilities and 60 centers located one tier below. The Trump administration continued funding for the 10 advanced facilities, but eliminated the 60 intermediate treatment centers.

His administration also got rid of a U.S. Agency for International Development program called PREDICT, established in 2009 to detect new zoonotic viruses (originating in animals, like Covid-19).

For the first time in its history, the CDC is headed by a physician with no expertise in public health. In the meantime, budget cuts to public health departments meant that until this week, only three health departments across the country were able to test for coronavirus.

Then of course, are the Trump administration cuts to health care in general, to pay for the $2 trillion in tax cuts for Americas wealthiest individuals: $1.4 trillion eliminated from Medicare, Medicaid and the Affordable Care Act, disproportionately affecting the poor, seniors, families and children. How will this affect care for patients who have Covid-19?

Under the ACA, the number of uninsured Americans fell from 40million to about 27.5million, but because of the Trump administrations withering attacks on the Obama-era program, the number of uninsured Americans increased last year to 29.5 million. Do you think that an uninsured waitress, like my sister-in-law, who cares for her wheelchair-bound husband, can skip work if she is sick?

The same is true for millions of Americans who are the sole wage earner for their families and, thanks to the continued erosion of the labor unions in this country, have no job security. How do you think that will affect efforts to control this emerging epidemic?

This new virus, along with sickening nearly a 100,000 people, and killing thousands of them, has highlighted the dangers of having a president with no concern for science or public health, a tax structure that cripples funding for vital health services and a nation alone among modern industrialized nation which does not guarantee health care for all.

Despite all the bad news, the risk of Covid-19 to children is very low: Fewer than 1% of diagnosed cases have occurred in those less than 18 years old, and they have tended to be mild cases, many without fever.

AAAAI Urges Patients on Montelukast to Contact Their Healthcare Provider – PR Web

March 5, 2020 medical

MILWAUKEE (PRWEB) March 04, 2020

With the U.S. Food and Drug Administration (FDA) today announcing it is requiring a boxed warning for montelukast due to the risk of neuropsychiatric events, such as agitation, depression, sleeping problems, and suicidal thoughts and actions, the American Academy of Allergy, Asthma & Immunology (AAAAI) is stressing the importance of contacting your healthcare provider if you are on this drug.

If you are taking montelukast and this is helpful for your symptoms, you should speak with your healthcare provider first prior to making a decision to suspend this medication, said AAAAI President David M. Lang, MD, FAAAAI, who is also Chair of the Allergy/Immunology Department in the Respiratory Institute at Cleveland Clinic.

Alternatively, if you begin taking montelukast, or if you have been taking montelukast, and you feel sad, experience mood changes, or vivid dreams, you should suspend montelukast and contact your healthcare provider, added Dr. Lang.

Montelukast, which is sold under the brand name Singulair and in generic form, is frequently prescribed. For asthma, montelukast can be used as the sole medication taken regularly for treatment of mild persistent asthma, or in combination with other medications (e.g., inhaled corticosteroids) for management of moderate or severe persistent asthma. Patients with asthma frequently also have allergic rhinitis.

Montelukast was initially FDA approved for management of asthma, and then was also approved for seasonal and perennial allergic rhinitis and for prevention of exercise-induced bronchospasm. FDA approval is as young as 12 months in asthma, two years in seasonal allergic rhinitis, six months in perennial allergic rhinitis, and six years in exercise induced bronchoconstriction.

The boxed warning that the FDA is now requiring strengthens an existing warning about the risk of neuropsychiatric events associated with the drug, and it advises healthcare providers to avoid prescribing montelukast for patients with mild symptoms, particularly those with allergic rhinitis.

You can learn more about asthma and allergic rhinitis on the AAAAI website, aaaai.org.

The American Academy of Allergy, Asthma & Immunology (AAAAI) represents allergists, asthma specialists, clinical immunologists, allied health professionals and others with a special interest in the research and treatment of allergic and immunologic diseases. Established in 1943, the AAAAI has over 7,000 members in the United States, Canada and 72 other countries.

BEYOND LOCAL: Sniffles and itchy eyes in winter? It could be allergies – TimminsToday

March 5, 2020 medical

Bad news, allergy sufferers winter wont necessarily give you a break.

There are what we call perennial allergens that never really go away, said Dr. Anne Ellis, professor and chair of the division of allergy and immunology at Queens University.

Things like house dust mites, which are microscopic spider-like insects that live in our mattress and pillow, certain moulds can live indoors in homes, and obviously if people have pets cats and dogs they usually allow them in the house and theyre not leaving, because its wintertime.

Mice also like to come inside during the winter, said Dr. Paul Keith, an associate professor in McMaster Universitys division of allergy and clinical immunology. These rodents can also be an allergy trigger for many people, he said, if they get into the house.

Part of the problem is that we spend more time indoors during the winter, Ellis said, which is not a great environment for allergy sufferers.

In winter, people usually keep their houses closed up and dont have air conditioners running or windows open which means allergens can build up in the closed area, she said. Heaters can make the air drier, which is also irritating for some.

These arent the same as seasonal allergies though.

Theres no pollen in the air right now, she said. Its tempting to think that theres something in the air when you have these intermittent mild melts. But usually whats happening there is that people who have allergies, they have hypersensitive airways anyway and so any changes in climate can trigger irritant-type symptoms in the nose.

Winter is also cold season, she said, and it can be tricky to tell the difference between an allergy and an infection.

Allergies typically would not cause you to have a fever, and you wouldnt get a sore throat.

Swollen lymph nodes and a general icky, not-great feeling are also probably a cold of some kind, not an allergy, she said.

If you do have allergies, there are things you can do to help lessen your symptoms, starting with trying to eliminate the allergen in your home.

With pets, you want to try to keep the pet out of the bedroom, so that [in] the room where you spend at least eight hours a day, youre not exposed to a higher level [of allergens], Keith said.

For dust mite allergy, we recommend covering the pillow and mattress to reduce your exposure, he said.

You should also change your sheets and pillowcases every week and wash them in hot water, Ellis said.

Similarly, Keith said, many people dont wash their winter coats very often, and these can also attract dust mites.

Air purifiers can make a difference, Ellis said, but they must be certified allergy-asthma friendly.

You may also want to try tackling your symptoms with medication. Saline nasal sprays can help wash allergens out of your nose, Keith said.

Pharmacies sell lots of very effective non-sedating antihistamines, Ellis said. She strongly recommends second-generation antihistamines, sold under brand names like Claritin and Allegra, over older antihistamines like diphenhydramine (Benadryl), because they have fewer side-effects and are more effective.

Nasal steroid sprays can also be effective, she said, though people need to be aware it can take a few days for the effect to kick in. You need to use it every day for at least a week to notice a significant improvement in your symptoms.

And, she said, if you find over-the-counter options dont work, you should consult a primary care provider or an allergist.

Allergy specialists love to see patients even with minor concerns, because we really like helping people for things that we know can be a burden to the patients who experience them.

Can the Weather Make You Sick? – FOX 15

March 5, 2020 medical

We have all heard the phrase put a jacket on or youll catch a cold. well there might be some truth to this. It turns out that the weather can actually help you get sick but not in the way that you might think. According to UL Assistant Professor of Immunology Ritwij Kulkarni, while the colder temperatures of this time of year might not directly make you sick they can help viruses survive longer.

Generally the way these viruses are transmitted transmitted through Aerosols so while you are speaking a little bit of spit comes out, sneeze a little bit of spit comes out. You can imagine that aerosol falls on the surface and surface is hot then it will get dried out quickly the viruses will not survive that you can imagine that all these things are going to happen more if if there is cold weather like it will take longer for these droplets to dry out.

On top of this, during the colder months we tend to stay inside more and with this the transmission of viruses and illnesses does increase.

Why we see these viruses are more common during cold months is because we are indoors. We are more in contact with each other in that time. Chances of transmission are higher and so thats why we get those infections at that time.

No matter the weather though there is one thing that you should always be doing to help keep yourself safe and that is to wash your hands.

Hand washing is the best thing that is going to clean your hands washing hands with warm water and soap; what we learn in elementary school singing happy birthday to you and making sure that youre washing hands.
