The Guardian has named the world's most popular coronavirus myths. Christina Pagel, Director of Clinical Operations Research at University College London, spoke about them in her article. She explained which facts about COVID-19 have been confirmed by science and which are just speculation.
A COVID-19 patient is not contagious if he has no symptoms of the disease
People who never develop symptoms of COVID-19 are less infectious than others, but they can still have a high viral load and can transmit the virus, according to the British expert. That being said, since people who feel well are more likely to be away from home than those who feel bad, they contribute greatly to the spread of the virus. People without symptoms are responsible for more than half of new infections, the author of the article argues.
After being fully vaccinated, a person with COVID-19 is not contagious
Pagel said there have been many documented cases of COVID-19 infection in fully vaccinated people, including severe ones. Vaccines are 50% -60% effective in preventing infection, the expert said. However, in the early stages of infection, vaccinated people have the same high viral load as unvaccinated people.
No vaccine needed after transferring coronavirus
It is not true. The presence of COVID-19 does provide protection against re-infection, but it is not as good as protection after vaccination. Immunity after vaccination lasts longer and is more resistant to new variants, the report says.
The vaccine is not needed with good immunity
Even with a strong immune system, you can get very sick with the coronavirus, including going to the hospital and dying, Pagel warns.
COVID is safe for children
Children are at a much lower risk of severe illness or long-term illness from COVID than adults, but they can still face it, the article notes.
Masks are not effective
“COVID-19 is primarily airborne and spread by people breathing, talking, screaming and singing,” Pagel writes, stressing that masks prevent breath from entering another person’s face.
“This wave of coronavirus will be the last …”
The author of the article recalls that the situation is unpredictable, and many experts expect the incidence of coronavirus to rise again with the onset of autumn and winter.
