Covid-19 Common Misconceptions

Misconceptions about COVID-19:

There’s a lot of information out there about coronavirus (COVID-19) and not all of it is true. How do you know if what you’re seeing online is fact or fiction? Most importantly, get your information from reputable sources like the Center for Disease Control and Prevention, Utah Department of Health, and Intermountain Healthcare. Here are common misconceptions about COVID-19.

Is COVID-19 increasing the risk of stroke in infected patients?

A recent case study published in the New England Journal of Medicine suggests the possibility that COVID-19 causes blood clots in some individuals; however, other health systems have not seen an increase in strokes. Regardless of virus or no virus, early identification and treatment of stroke gives the best chance for a positive outcome. It is critical that patients seek help from EMS rather than arriving to the hospital on their own if they are experiencing any signs or symptoms of a stroke. This helps direct the patient to the most appropriate stroke center and allows that hospital to prepare for the most efficient response.

At what point would it be more beneficial to test for immunity rather than focusing on screening the public for COVID-19?

One of the problems with testing for immunity is that we don’t currently have a reliable test available. Antibody testing tells us if someone has been exposed to proteins related to viruses, like COVID-19. These proteins cause our bodies to develop antibodies that are part of our immune response. There are several proteins associated with this new coronavirus that cause antibody production, but there are some similar proteins from other coronaviruses, too. At this time, we don’t know if the presence of these antibodies provides immunity to COVID-19.

Should you really wipe down all your food from the grocery store before putting it away?

Currently, there are no reports of people contracting COVID-19 from food or packaging from grocery stores. You can wipe down packing and allow to air dry as a precaution, but it is not recommended that you wipe down non-packaged food you will ingest with chemical cleaners. To prevent the spread of infection, it’s best practice to regularly clean your kitchen, sanitize kitchen counters, and clean produce before eating.

Is the public water supply contaminated with COVID-19?

There’s no evidence that the virus has spread through the water supply. In fact, the treatment in water facilities protects us from pathogens.

Should patients cancel any standing appointments with their healthcare provider in order to avoid hospitals and medical offices where patients infected with COVID-19 may be present?

It’s very important to monitor your health as you normally would and follow up with your physician as scheduled. Many providers are now offering video visits to help sustain social distancing and keep patients and caregivers safe. Call your provider to find out if your appointment can be provided through a video visit. Not all conditions can be seen via video, but your provider can decide the best type of appointment for you.


If I feel sick and I’m worried I may have contracted COVID-19, should I visit an emergency room of InstaCare immediately?

If you’re experiencing symptoms of COVID-19, find out if you should be tested by calling the COVID-19 Hotline, for more information click here. Calling ahead allows a medical professional to assess your symptoms over the phone and determine if you should be tested for COVID-19. You will likely be referred to testing if you have one of the COVID-19 symptoms (subject to testing capacity). Symptoms of COVID-19 can include: 

  • Fever
  • Cough
  • Difficulty breathing
  • Muscle aches and chills
  • Decreased sense of smell or taste
  • Sore throat

Severe symptoms: If you, your child, or someone you are with is experiencing difficulty breathing and extreme shortness of breath; new confusion or inability to waken/arouse; bluish lips or face; or any other symptoms of a medical emergency, call 911.

If I don’t have symptoms of COVID-19 do I still need to wear a mask?

Edward Stenehjem, MD, an infectious diseases expert at Intermountain Healthcare, recommends wearing a mask when you must be in a public place where social distancing is difficult, like a grocery store. But, he cautions, don’t assume a mask automatically means you’re safe. “The homemade cloth masks are a benefit to the community, not the person wearing it,” he said. “That’s because those who don’t have any symptoms might still have the virus, and these masks, when made and worn correctly, help prevent transmission.”

Can I contract COVID-19 from pets or animals?

While the World Health Organization acknowledges there are instances of animals and pets of COVID-19 patients becoming infected with the disease, further evidence is needed to understand if animals and pets can spread the disease. While animals can spread viruses between one another, they are genetically distinct from humans making it extremely hard for viruses to pass between pets and their owners. However, it’s always a good idea wash your hands with soap and water after contact with pets.

Will drinking and gargling warm water every 15 minutes kill or flush out COVID-19 from my system?

No. While staying hydrated is very important, these practices do not prevent COVID-19. The best infection prevention methods for COVID-19 include wearing appropriate personal protective equipment (PPE) at work, practicing social distancing, washing your hands, and having good hygiene.

I’ve heard we can expect the spread of COVID-19 to slow as the weather warms. However, it seems like the virus is spreading now in areas like Singapore, where it’s very warm. How long will this virus live at temperatures above 100°F?


Generally, coronaviruses survive for shorter periods at higher temperatures and higher humidity than in cooler or dryer environments. However, it’s not yet known whether weather and temperature affect the spread of COVID-19. Some other viruses, like those that cause the common cold and flu, spread more during cold weather months but that doesn’t mean it’s impossible to become sick with these viruses during other months. There’s much more to learn about the transmissibility, severity, and other features associated with COVID-19 and investigations are ongoing.

I’ve heard that COVID-19 can last on surfaces from 48 hours to 17 days. How long can it actually survive on surfaces?

It’s not certain how long the virus that causes COVID-19 survives on surfaces, but according to the World Health Organization, the virus seems to behave like other coronaviruses. Studies suggest that coronaviruses in general may persist on surfaces for a few hours or up to several days. It also varies under different conditions (e.g. type of surface, temperature or humidity of the environment).

Cleaning visibly dirty surfaces with simple disinfectants is a best practice measure to protect yourself and others from COVID-19 and other viral respiratory illnesses. After cleaning, wash your hands with soap and water, or use an alcohol-based hand sanitizer or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

I thought COVID-19 was mainly respiratory issues, but now I’m hearing there are GI (gastrointestinal symptoms too. Is that true?

COVID-19 has a wide range of symptoms. Common symptoms include cough, fever, tiredness, and difficulty breathing in severe cases. Less common symptoms have included headache, sore throat, and rhinorrhea, anosmia (loss of smell), and gastrointestinal symptoms (e.g. nausea and diarrhea). While experts in consumer behavior say a surge in panic buying is not a surprise during a global pandemic, it’s not necessary to buy large amounts of products like toilet paper to combat COVID-19 symptoms.

Ventilators are being used to treat COVID-19 patients. Is it true that ventilators are lifesaving in the short term, but can cause pneumonia or lung damage and more permanent harm in the long-term?

It’s well known throughout the healthcare community that ventilator-associated lung injury is a risk—particularly with patients who are intubated with ARDS (acute respiratory distress syndrome). That said, here are a few important things to remember: 

  1. In general terms, patients intubated in these settings would almost certainly die without the ventilator.
  2. We have learned a great deal in recent years about how to reduce the risk of ventilator-associated lung injury. Employing those lessons has significantly reduced the risk.
  3. Ventilator-associated pneumonia does occur, but the risk is very low with all the steps we currently employ.

So, while it’s accurate to say there are risks when patients are intubated, particularly for long periods like COVID-19 patients, the benefit far exceeds the risk in patients, particularly those who don’t have pre-existing lung conditions. 

What is the risk of disease transmission from clothing exposed during work?

While there have been no documented cases of transmission of COVID-19 via clothing and shoes at this point, following proper personal protective equipment guidelines at work and cleaning and disinfecting clothes properly is essential for preventing disease transmission.


1) “What EXACTLY is in the COVID-19 vaccine?”

Here is a full list of ingredients in the Pfizer vaccine (pulled directly from the Canadian Product Monograph) with an added aside as to why they’re in there:

–  Active Ingredient: modified messenger RNA, which encodes the viral spike glycoprotein of SARS-CoV-2 (the COVID-19 virus). The spike is the part of the virus that allows it to enter our cells so that the virus can then go on to cause infection. On its own, it isn’t harmful (it will not give us COVID-19) but it allows our immune system to build antibodies against it so that if the virus ever does enter our body, our immune system can recognize and attack it.

– Lipids (including cholesterol): These encase the mRNA to protect it so that it can enter our cells without being broken down in the body prematurely.

– Salts: Potassium chloride, monobasic potassium phosphate, sodium chloride, dibasic sodium phosphate dihydrate. These all keep the pH (or acidity) of the vaccine at the required level.

– Sucrose: keeps the vaccine stable during transport and storage

– Saline solution is mixed with the vaccine before injection so that the injection contains more or less the same salt content of the blood

I do want to point out that NO preservatives are included in the vaccine (no thimerosal, no formaldehyde, etc.), which are common concerns for many patients receiving vaccines in general (I will not go into this here for the interest of keeping this post relatively brief, but if anyone has any questions about these guys, please feel free to reach out). Also, I can confirm that there are absolutely ZERO microchips in the vaccine, I promise.…/pfizer-biontech-covid……/appendices/b/excipient-table-2.pdf…/what-are-the…/

  1. “What are the side effects of this vaccine?”

– The main side effects that have been discovered in in the trials (where tens of thousands of people have received the vaccine) are injection site pain, fatigue, headache, muscle pain, chills, joint pain and fever – usually mild-moderate in intensity and resolve within a few days.

– Severe side effects are extremely rare. One misconception I’ve seen on the internet seems to be that the COVID-19 vaccine causes death. To clarify, 6 people in total died during the study – HOWEVER, it is important to mention that 4 of these people were in the placebo group (did not receive the vaccine) and 2 people were in the control group (received the vaccine). The deaths occurred due to different causes (ie. Heart attack, stroke) at the same rate they would in the general population (aka appear to be unrelated to the vaccine). If anyone would like to read the trial results, I have linked them under this response.……

  1. “How can we say it’s safe and effective when it has been developed so quickly? Also, I’ve heard the mRNA vaccine technology is completely new. How do I know that it’s safe?”

– A lot of people have the question regarding the safety and efficacy of the vaccine after being developed in such a short period of time (myself included at first!). What makes the development of this vaccine different from others, aside from a difference in vaccine technology, is that this is the first time that the ENTIRE WORLD has come together to fund and develop a vaccine. I mean, thinking about it, the best researchers in the world coming together to work on this – how cool is that! A lot of times in science, funding + more scientists = faster outcomes. Is this the fastest we’ve ever developed a vaccine? Yes, but more scientists added to all of the scientific advances over the years + COVID vaccine research being pushed to the front of the priority line has made the quick development possible. All safety checks were kept in the development of the vaccine and no corners were cut during the development process or in clinical trials.

– Fun fact: Did you know that the idea of mRNA vaccine technology first came about 30 years ago? Although there has never been an mRNA vaccine approved for distribution, it HAS been studied in human trials for diseases including rabies. Why didn’t these vaccines come to the market? Well – there was no pressing reason to continue the research given that vaccines that we had were sufficiently effective or the outbreaks no longer posed a threat (ie. SARS). There was no compelling reason (in the eyes of those funding the studies) to donate large sums of money back then to mRNA research – but there was this time around!

– Okay so…what does this tell us in terms of safety? mRNA vaccines have been administered to humans in trials since 2013, and this far down the line no long-term safety issues have arisen. Using the rabies mRNA vaccine trial as an example, most side effects experienced occurred in a short period of time following vaccine administration. In terms of long-term side effects of the COVID-19 vaccine that may be years away, it isn’t known if there will be any, I will agree. However, given how the vaccine actually works, these are not expected to be severe if even present. mRNA is degraded really fast in the body and doesn’t hang around long, so the likelihood of it causing any issues down the road is minimal. All in all, the small risk of experiencing side effects from a vaccine from a scientific standpoint is by far less than the risk of experiencing side effects from contracting COVID-19.

  1. “I’ve heard that vaccines cause autism, is this true? Can the COVID-19 vaccine cause autism?”

Vaccines do NOT cause autism. There have been many large studies over many years that have shown this not to be the case. This initial concern came from a single small study (involving 12 children) that a doctor published in 1998 showing a link between the MMR vaccine and autism. However, this doctor’s results were found to be incorrect and his paper was withdrawn, and he LOST HIS MEDICAL LICENSE. Every single study done ever since has shown no link between vaccines and autism.

  1. “How can a vaccine go from being stored at -70 degrees Celsius to being injected into my body?”

– mRNA is super unstable at room temperature. If we kept the vaccine at room temperature all of the time, it would degrade before it even got to the patient! So, it’s kept at a very cold temperature to allow it to stay stable and then it is thawed at room temperature before being diluted with saline solution and then administered.…/pfizer-biontech-covid…

  1. “I’m young, healthy and will probably be fine if I contract COVID-19. So why should I consider getting the vaccine?”

While sure, not everyone who contracts COVID-19 will get extremely sick or die, younger individuals aren’t immune from having serious and sometimes fatal reactions to the COVID-19 virus. You truly do not know how it will affect you until you get it. Also, even if you do get it and are fine…. will those around you be fine if you contract it and then spread it to them? (Edit: While we don’t yet know if/to what extent COVID-19 is transmissible after receiving the vaccine, researchers are optimistic that transmission will be reduced – this is just something that needs more time to be studied and thus why they recommend still wearing masks after receiving the vaccine until a sufficient portion of the population is vaccinated, or until we know for sure. We DO know that the virus is relatively highly transmissible if you contract COVID-19 in the absense of vaccination.) We also don’t know the long-term effects of having COVID-19, as it is a new disease. The PhD candidate that I previously mentioned, Sarah, related this to the Chickenpox virus. The virus appeared to be relatively harmless to get as a child (although bothersome), however YEARS later, now we know that it can actually re-activate as shingles. Is this the same with COVID-19? Could it be worse? We just don’t have that information yet. As previously mentioned, as a healthcare professional with knowledge of vaccines and how they work, I can assure you that the low risk of a side effect from a vaccine is far better than the risks associated with contracting COVID-19 itself.…/vaccines/vaccine-benefits.html…
