Coronavirus myths explored
As the coronavirus continues to make the news, a host of untruths has surrounded the topic. In this special feature, we address some of these myths and conspiracies.
The novel coronavirus, now known as SARS-CoV-2, has spread from Wuhan, China, to every continent on Earth except Antarctica.
The World Health Organization (WHO) officially changed their classification of the situation from a public health emergency of international concern to a pandemic on March 11.
To date, the novel coronavirus — currently dubbed “severe acute respiratory syndrome coronavirus 2,” or SARS-CoV-2 for short — has been responsible for over 1.3 million infections globally, causing nearly 75,000 deaths. In the U.S., almost 370,000 people have contracted the virus, and nearly 11,000 people have died.
As ever, when the word “pandemic” starts appearing in headlines, people become fearful, and with fear come misinformation and rumors.
Here, we will dissect some of the most common myths that are currently circulating on social media and beyond.

1. Spraying chlorine or alcohol on skin kills viruses in the body
Applying alcohol or chlorine to the body can cause harm, especially if it enters the eyes or mouth. Although people can use these chemicals to disinfect surfaces, they should not use them on skin.
These products cannot kill viruses within the body.
2. Only older adults and young people are at risk
SARS-CoV-2, like other coronaviruses, can infect people of any age. However, older adults or individuals with preexisting health conditions, such as diabetes or asthma, are more likely to become severely ill.
3. Children cannot catch COVID-19
All age groups can become infected. Most cases, so far, have been in adults, but children are not immune. In fact, preliminary evidence shows that children are just as likely to become infected, but their symptoms tend to be less severe.
4. COVID-19 is just like the flu
SARS-CoV-2 causes illness that does, indeed, have flu-like symptoms, such as aches, fever, and cough. Similarly, both COVID-19 and flu can be mild, severe, or, in rare cases, fatal. Both can also lead to pneumonia.
However, the overall profile of COVID-19 is more serious. Estimates vary, but its mortality rate seems to be between about 1% and 3%.
Although scientists are working out the exact mortality rate, it is likely to be many times higher than that of seasonal flu.
5. Everyone with COVID-19 dies
This statement is untrue. As we have mentioned above, COVID-19 is only fatal for a small percentage of people.
In a recent report, the Chinese Center for Disease Control and Prevention concluded that 80.9% of COVID-19 cases were mild.
The WHO also report that around 80% of people will experience a relatively mild form of the disease, which will not require specialist treatment in a hospital.
Mild symptoms may include fever, cough, sore throat, tiredness, and shortness of breath.
6. Cats and dogs spread coronavirus
Currently, there is little evidence that SARS-CoV-2 can infect cats and dogs. However, in Hong Kong, a Pomeranian whose owner had COVID-19 became infected. The dog did not display any symptoms.
Scientists are debating the importance of this case to the epidemic. For instance, Prof. Jonathan Ball, Professor of Molecular Virology at the University of Nottingham in the United Kingdom, says:
“We have to differentiate between real infection and just detecting the presence of the virus. I still think it’s questionable how relevant it is to the human outbreak, as most of the global outbreak has been driven by human-to-human transmission.”
He continues: “We need to find out more, but we don’t need to panic — I doubt it could spread to another dog or a human because of the low levels of the virus. The real driver of the outbreak is humans.”
7. Face masks protect against coronavirus
Healthcare workers use professional face masks, which fit tightly around the face, to protect them against infection.
Disposable masks are unlikely to provide such protection, and they will not block tiny viral particles. However, a cloth mask can help prevent the spread of droplets.
The Centers for Disease Control and Prevention (CDC) recommend that all people wear cloth face masks in public places where it is difficult to maintain a 6-foot distance from others. This will help slow the spread of the virus from asymptomatic people and those who do not know that they have contracted the virus.
When wearing a mask, it is essential to continue with other precautions, such as not touching the face and practicing physical distancing.
Instructions for making masks at home are available here.
Surgical masks and N95 respirators provide greater protection, but these are reserved for healthcare workers only.
8. Hand dryers kill coronavirus
Hand dryers do not kill coronavirus. The best way to protect yourself and others from the virus is to wash your hands with soap and water or an alcohol-based hand rub.
9. SARS-CoV-2 is just a mutated form of the common cold
Coronaviruses are a large family of viruses, all of which have spiky proteins on their surface. Some of these viruses use humans as their primary host and cause the common cold. Other coronaviruses, such as SARS-CoV-2, primarily infect animals.
Both Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) began in animals and passed into humans.
10. You have to be with someone for 10 minutes to catch the virus
The longer someone is with an infected person, the more likely they are to catch the virus, but it is still possible to catch it in less than 10 minutes.
11. Rinsing the nose with saline protects against coronavirus
There is no evidence that a saline nose rinse protects against respiratory infections. Some research suggests that this technique might reduce the symptoms of acute upper respiratory tract infections, but scientists have not found that it can reduce the risk of infection.
12. You can protect yourself by gargling bleach
There are no circumstances in which gargling bleach might benefit your health. Bleach is corrosive and can cause serious damage.
13. Antibiotics kill coronavirus
Antibiotics only kill bacteria; they do not kill viruses.
14. Thermal scanners can diagnose coronavirus
Thermal scanners can detect whether someone has a fever. However, other conditions, such as seasonal flu, can also produce fever.
In addition, symptoms of COVID-19 can appear 2–10 days after infection, which means that someone infected with the virus could have a normal temperature for a few days before a fever begins.
15. Garlic protects against coronaviruses
Some research suggests that garlic might slow the growth of some species of bacteria. However, COVID-19 is caused by a virus, and there is no evidence that garlic can protect people against COVID-19.
16. Parcels from China can spread coronavirus
From previous research into similar coronaviruses, including those that cause SARS and MERS and are similar to SARS-CoV-2, scientists believe that the virus cannot survive on letters or packages for an extended time.
The CDC explain that “because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures.”
17. Home remedies can cure and protect against COVID-19
No home remedies can protect against COVID-19, including vitamin C, essential oils, silver colloid, sesame oil, garlic, fish tank cleaner, burning sage, and sipping water every 15 minutes.
The best approach is to adopt a good handwashing regimen and to avoid places where there may be unwell people.
