As 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 conspiracy theories.
The novel coronavirus, SARS-CoV-2, has spread from Wuhan, China, to every continent except Antarctica.
The World Health Organization (WHO) changed their classification of the situation from a public health emergency of international concern to a pandemic on March 11, 2020.
The virus has been responsible for tens of millions of infections globally, causing more than a million deaths. The United States has been the most affected country.
As ever, when the word “pandemic” began appearing in headlines, people became fearful — and with fear came misinformation and rumors.
Below, we dissect some of the most common myths currently circulating on social media and beyond.
Stay informed with live updates on the current COVID-19 outbreak
1. Spraying chlorine or alcohol on the skin kills viruses in the body
Applying alcohol or chlorine to the skin can cause harm, especially if it enters the eyes or mouth. These chemicals can disinfect surfaces, but people should not use them on their bodies.
Also, these products cannot kill viruses inside the body.
2. Only older adults and people with preexisting conditions are at risk of infections and complications
SARS-CoV-2, like other coronaviruses, can transmit to people of any age. However, older adults and individuals with preexisting health conditions, such as diabetes, obesity, or asthma, are more likely to become severely ill.
While people under 40, including children, are less likely to become severely ill with COVID-19, the disease can lead to complications and death in anyone.
3. Children cannot get COVID-19
Anyone, of any age, can develop the infection that causes COVID-19.
So far, most COVID-19 cases have been in adults, but children are not immune. That said, most children who develop COVID-19 have mild symptoms or none at all.
Also, on May 15, 2020, the WHO released a commentary about an inflammatory condition in children and adolescents that may have links with COVID-19.
The condition, called multi-system inflammatory syndrome in children, known as MIS-C, has features similar to Kawasaki disease and toxic shock syndrome.
Scientists currently know little about this condition, but research from May suggests that it is rare, “probably affecting no more than 1 in 1,000 children exposed to SARS-CoV-2.”
4. COVID-19 is just like the flu
Infection with the virus SARS-CoV-2 can cause COVID-19, an illness that can cause flu-like symptoms, such as body aches, a fever, and a cough. Symptoms of either COVID-19 or the flu can be mild, severe, or rarely, fatal. Both illnesses can also cause pneumonia.
However, the overall profile of COVID-19 is more serious. Different countries have reported different mortality rates, and the case fatality rate in the U.S. appears to be around 2.6%.
While scientists are still determining the exact mortality rate based on developing data, it is likely to be many times higher than that of the seasonal flu.
5. Everyone with COVID-19 dies
This is false. As we explain above, COVID-19 is fatal for a small percentage of people who develop the illness.
The WHO have reported that around 80% of people with COVID-19 experience a relatively form of the illness and do not need specialist treatment in a hospital. Mild symptoms may include a fever, a cough, a sore throat, tiredness, and shortness of breath.
Also, many people with the underlying infection experience no symptoms.
6. Cats and dogs spread the coronavirus
There have been several reports of pets developing the infection, including in the U.S. In most cases, the pets became sick after coming into contact with people who had COVID-19.
According to the Centers for Disease Control and Prevention (CDC), “There is no evidence that animals play a significant role in spreading the virus that causes COVID-19.”
Scientists are debating the importance of these cases in animals. For instance, Jonathan Ball, a 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.”
7. Face masks always protect against the coronavirus
Healthcare workers use professional face masks that fit tightly to protect themselves from infections.
Disposable and cloth masks can protect against droplets, but neither can protect against aerosolized particles.
The CDC recommend that all people wear cloth face masks in public areas where it is difficult to maintain a 6-foot, or 2-meter, distance from others. This helps slow the spread of the virus.
Even while wearing a mask, it is essential to continue with other precautions, such as not touching the face, physical distancing, and washing the hands frequently.
Surgical masks and N95 respirators provide greater protection, but reserve these for healthcare workers.
8. Hand dryers kill the coronavirus
Hand dryers do not kill SARS-CoV-2. The best way to protect oneself and others from the virus is to wash the hands with soap and water frequently for at least 20 seconds at a time.
When this is not possible, use an alcohol-based hand sanitizer.
9. SARS-CoV-2 is just a mutated form of the common cold virus
Coronaviruses are a large family, and each has spiky proteins on their surface. Some use humans as their primary host and cause the common cold.
Other coronaviruses, including SARS-CoV-2, primarily infect animals.
Like COVID-19, Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) are caused by coronaviruses. These viruses also initially passed to humans from animals.
10. You have to be with someone for 10 minutes to catch the virus
The longer a person is close to someone with the infection, the likelier the virus is to transmit. However, the virus can pass from person to person in under 10 minutes.
11. Rinsing the nose with saline protects against the coronavirus
There is no evidence that a saline nasal rinse protects against any respiratory infections.
Some research suggests that a rinse might ease the symptoms of acute upper respiratory tract infections, but scientists have not found that this technique reduces the risk of infection.
12. You can protect yourself by gargling bleach
People should never put bleach in their mouths. Gargling bleach could never benefit a person’s health.
Bleach is corrosive and can cause serious damage.
13. Antibiotics kill the coronavirus
Antibiotics only kill bacteria. They do not kill viruses.
14. Thermal scanners can diagnose the coronavirus
Thermal scanners can detect whether someone has a fever — which might result from any number of health issues.
Symptoms of COVID-19 can appear 2–14 days after the infection develops. This means that even if a person develops symptoms, they may have a normal temperature for days before a fever begins.
15. Garlic protects against coronaviruses
Some research suggests that garlic may slow the growth of some species of bacteria. COVID-19 results from a virus, not bacteria.
There is no evidence that garlic can protect people from COVID-19.
16. Parcels from China can spread the coronavirus
From previous research into coronaviruses similar to SARS-CoV-2, including those that cause SARS and MERS, scientists believe that the virus cannot survive on letters or packages for extended periods.
The CDC explain that “Although the virus can survive for a short period on some surfaces, it is unlikely to be spread from domestic or international mail, products, or packaging.”
17. Home remedies can cure and protect against COVID-19
No home remedies can protect against COVID-19. This goes for vitamin C, essential oils, silver colloid, sesame oil, garlic, fish tank cleaner, sage, or water, even when a person sips it every 15 minutes.
The best approach is to wash the hands frequently, for 20 seconds at a time, to use an alcohol-based hand sanitizer, to wear a face covering in public, and to avoid crowded places.
18. You can catch the coronavirus from eating Chinese food in the US
No, you cannot.
19. You can catch the coronavirus from urine and feces
This is likely false, but the jury is currently out. According to Prof. John Edmunds, from the London School of Hygiene & Tropical Medicine, in the U.K.:
“It isn’t a very pleasant thought, but every time you swallow, you swallow mucus from your upper respiratory tract. In fact, this is an important defensive mechanism. This sweeps viruses and bacteria down into our gut where they are denatured in the acid conditions of our stomachs.”
“With modern, very highly sensitive detection mechanisms, we can detect these viruses in feces. Usually, the viruses that we can detect in this way are not infectious to others, as they have been destroyed by our guts.”
However, it is worth noting that some research suggests that viruses similar to SARS-CoV-2 might persist in feces. A research letter in JAMA also concludes that SARS-CoV-2 is present in feces.
20. The virus will die off when temperatures rise
Some viruses, such as cold and flu viruses, spread more easily in colder months. This does not mean that their transmission stops in warmer weather.
As it stands, scientists do not know how temperature changes influence the behavior of SARS-CoV-2.
21. The coronavirus is the deadliest virus known to humans
While SARS-CoV-2 does appear to be more dangerous than influenza viruses, it is not the deadliest virus that people have faced. Others, such as the Ebola virus, have higher mortality rates.
22. Flu and pneumonia vaccines can protect against COVID-19
Because SARS-CoV-2 is distinct from other viruses, no existing vaccines can protect against it.
23. The virus originated in a laboratory in China
There is no evidence to back up this rumor, which has circulated on the internet. As a recent study demonstrates, SARS-CoV-2 is a natural product of evolution.
Some researchers believe that SARS-CoV-2 jumped from pangolins to humans. Others think that it passed to us from bats, like SARS did.
24. The outbreak began because people ate bat soup
While scientists are confident that the virus started in animals, there is no evidence that soup was involved.
25. 5G helps SARS-CoV-2 spread
As the world becomes more connected, some regions are rolling out 5G mobile technology. This has prompted a raft of conspiracy theories.
One of the most recent to emerge is that 5G is responsible for the swift spread of SARS-CoV-2 across the globe. This is a myth.
Some people believe that 5G helps viruses communicate, often citing a paper from 2011. In this study, the authors conclude that bacteria can communicate via electromagnetic signals.
However, experts dispute this theory. In any case, SARS-CoV-2 is a virus, not a bacterium.
Wuhan was one of the first cities to trial 5G in China, which helps explain the origin of some of these theories. However, Beijing, Shanghai, and Guangzhou also rolled out 5G at a similar time.
It is also worth noting that COVID-19 has significantly impacted countries with very little 5G coverage, such as Iran.
26. Drinking alcohol reduces the risk of infection
The WHO have released a response to the series of myths surrounding alcohol and COVID-19. They explain that while alcohol can disinfect the skin, it does not have this effect inside the body.
They continue, “Consuming any alcohol poses health risks, but consuming high-strength ethyl alcohol (ethanol), particularly if it has been adulterated with methanol, can result in severe health consequences, including death.”
Also, in a fact sheet on the subject, they explain that “Alcohol use, especially heavy use, weakens the immune system — and thus reduces the ability to cope with infectious diseases.”
And because alcohol is associated with a number of diseases, it may make people more vulnerable to COVID-19.
27. Injecting or consuming bleach or disinfectant kills the virus
Consuming or injecting disinfectant or bleach does not wipe out viruses in the body, and it can be extremely dangerous.
As Dr. Wayne Carter, an associate professor at the University of Nottingham’s Faculty of Medicine & Health Sciences, in the U.K., explains, “Disinfectants and bleach are strong oxidizing agents, useful to kill bacteria or viruses when they are deposited on surfaces, but these agents should not be ingested or injected. These agents can cause severe tissue burns and blood vessel damage.”
Dr. Penny Ward, a visiting professor of pharmaceutical medicine at King’s College London, in the U.K., notes, “Drinking bleach kills. Injecting bleach kills faster.”
28. You can contract the coronavirus in swimming pools
As the CDC observe, no evidence suggests that SARS-CoV-2 transmits via the water in swimming pools, hot tubs, or water parks. If this water is disinfected with chlorine or bromine, it should inactivate the virus.
Still, the virus can transmit in all the usual ways in these and any other shared spaces. A person contracts a SARS-CoV-2 infection by inhaling respiratory droplets that contain the virus or coming into contact with infected surfaces.
As in other public places, the CDC recommend staying 6 feet, or 2 meters, away from others at pools and water parks and wearing cloth face coverings when not in the water.
People who operate pools should take extra care to clean and disinfect all facilities.
What should we do?
The CDC recommend the following simple ways to reduce the spread of SARS-CoV-2:
avoiding close contact with people who seem ill or report symptoms
trying not to touch the eyes, nose, or mouth
staying home if any symptoms appear
sneezing into a tissue, then throwing it in the trash, or sneezing into the crook of the elbow
using standard cleaning sprays and wipes to disinfect frequently touched objects and surfaces
washing the hands with soap regularly, for at least 20 seconds at a time
using an alcohol-based hand sanitizer when soap and water are unavailable
wearing a cloth face covering in stores, pharmacies, and other public settings
Although there are notable exceptions, most evidence suggests that COVID-19 is much less dangerous for children than it is for adults and infants.
Knowing the symptoms of COVID-19 in children can help parents and caregivers identify the emergency warning signs and seek appropriate care.
This article covers the symptoms of COVID-19 in children, some potential complications, and when to see a doctor.
Symptoms of COVID-19 in children
Data from both China and the United States on children with SARS-CoV-2, the virus that causes COVID-19, suggest that the risk of severe illness is lower in children than it is in adults.
A study of 2,752 cases of COVID-19 in children found that three had died, though the exact cause of death in each case is under investigation.
Current evidence suggests that infants have a higher rate of hospitalization, with some requiring treatment in intensive care units.
In China, more than 90% of children with COVID-19 had no symptoms and only mild-to-moderate disease.
The following are some symptoms that children may experience:
Fever: Although most adults report a fever with COVID-19, fevers are slightly less common among children, according to data from the Centers for Disease Control and Prevention (CDC).
Flu-like symptoms: Around 73% of children with COVID-19 had a fever, cough, or shortness of breath. Shortness of breath is much less common in children. In one analysis, 43% of adults and just 13% of children had this symptom.
Respiratory tract symptoms: Children with mild forms of the illness may develop a runny nose, cough, or sore throat.
Digestive symptoms: Some children develop vomiting, diarrhea, or nausea.
Changes in the sense of smell: A 2020 analysis found that most adults with COVID-19 lose their sense of smell. Researchers have not assessed this symptom in young people, but children may also lose their sense of taste or smell.
Pain: Children with COVID-19 may develop muscle pain or a headache.
Behavioral changes: Children may be moody or cry more often, especially if they are too young to verbally express their emotions or identify their symptoms. Some children may also be anxious, especially if they know that COVID-19 can be dangerous.
Overall, COVID-19 symptoms tend to be less severe in children. Children are also less likely than adults to report each symptom.
Complications
Children with underlying health conditions — such as lung disease, heart disease, or a weak immune system — are more susceptible to serious COVID-19 complications.
A CDC study that assessed COVID-19 symptoms in children used data on hospitalization and underlying medical conditions for 295 children. In that group, 77% of hospitalized children had at least one other medical condition. This suggests that comorbidities are a significant risk factor for hospitalization in children.
Even among high risk children, however, the risk of dying from COVID-19 is very low. Of 2,143 children included in a Chinese CDC study, just one 14-year-old died. Also, as above, 3 out of 2,572 children in a CDC study died, though the cause in each case is currently unconfirmed.
Some other potential complications include:
organ failure
the need to use a ventilator
sepsis, which is a severe infection that affects many systems in the body
heart failure
issues that can cause life threatening blood clots
Children with severe symptoms usually develop them within a week of getting sick.
A small number of children have also developed symptoms of multisystem inflammatory syndrome in children (MIS-C). This syndrome can cause symptoms that resemble those of toxic shock syndrome and Kawasaki disease. Without treatment, it may be fatal.
Children with MIS-C may develop a rash, stomach pain, bloodshot eyes, exhaustion, diarrhea, or vomiting.
The following symptoms require emergency medical attention:
confusion
fever
chest pressure or pain
neck pain
difficulty breathing
blue or white face, fingers, or toes
an inability to stay awake
severe stomach pain
When to see a doctor
Most children have either no symptoms or only mild-to-moderate ones. These children do not need to go to the hospital or see a doctor.
However, parents and caregivers should call a pediatrician if their child shows any symptoms of COVID-19. The pediatrician can offer advice on which symptoms to watch and some suggestions for home treatment.
In some areas, a child may also need a referral for COVID-19 testing.
Call a doctor if:
the child seems very ill
they develop a rash
their symptoms get better and then get worse again
they recover from COVID-19 but then develop inflammatory symptoms, such as a rash, fever, or bloodshot eyes
Go to the emergency room if a child:
gasps for air or shows signs of respiratory distress, such as bluish lips, breathing very fast, or difficulty breathing
seems confused, seems lethargic, or cannot wake up
reports pressure or pain in their chest
has symptoms of organ failure, such as intense pain in the stomach, difficulty passing urine, an inability to move without help, or an inability to think clearly
Treatment
No medication can cure COVID-19. Although hospitals and researchers are exploring experimental treatments, these are currently only available to very sick people.
Most children can recover with home treatment. To help a child with COVID-19:
Encourage them to rest.
Give them lots of fluids to prevent dehydration.
Check on them regularly to ensure that they are not getting worse.
Ask a doctor about over-the-counter pain and fever relievers.
Have them stay in a single area of the house, if possible. Clean and disinfect all surfaces they touch, and encourage other family members to avoid them. Also, wear a face mask when caring for a sick child.
Parents and caregivers may find these guidelines challenging to follow when caring for a child or infant. The CDC offer some advice on how to manage risk around children.
It may also be a good idea to speak to a medical professional about how best to care for a child with a suspected SARS-CoV-2 infection. Children under 2 years of age should not wear a face covering.
Very sick children may need to go to the hospital. In the hospital, doctors will focus on managing the child’s symptoms. They might need oxygen, intravenous fluids, or steroid medications to help them breathe.
Rarely, a child might need a ventilator if they cannot breathe well on their own.
