The COVID-19 pandemic was caused by a novel coronavirus, first isolated in January 2020. But a viral video has been spreading a conspiracy theory that the pandemic has actually been a plot to poison people with snake venom.
It’s not known yet whether the omicron variant causes more or less severe COVID-19 than the delta variant, although some preliminary indications suggest omicron infections might be milder. A Facebook post nevertheless claims, without evidence, that the “toxicity” of omicron is 5 times higher than delta and that its mortality rate is higher.
NBA star Bradley Beal made some misleading comments — shared in viral video clips — about the effectiveness of COVID-19 vaccines. No vaccine is 100% effective, but clinical trials and studies show the COVID-19 vaccines are very effective at preventing illness, particularly serious illness, including for those previously infected, such as Beal.
Q: How do people who have not been vaccinated against COVID-19 pose a risk to people who have been vaccinated?
A: An unvaccinated person who is infected with COVID-19 poses a much greater risk to others who are also unvaccinated. But vaccines are not 100% effective, so there is a chance that an unvaccinated person could infect a vaccinated person — particularly the vulnerable, such as elderly and immunocompromised individuals.
SARS-CoV-2, the virus that causes COVID-19, is spread from person to person through respiratory droplets or particles when infected people cough, sneeze, talk or breathe.
Most often, transmission occurs when such droplets or particles are breathed in or land in or on a person’s eyes, nose or mouth. As a result, risk is thought to be highest when people are in close contact with one another, typically within 6 feet or so of an infected person,
