Does the COVID-19 Omicron variant spreads more easily?

New variants of the virus are expected to occur. Slowing the spread of the virus, by protecting yourself and others, can help slow the emergence of new variants. The Omicron variant causes more infections and spreads faster than the original SARS-CoV-2 strain of the virus that causes COVID-19.

Is the Delta variant more contagious than the original strain of COVID-19?

People infected with the Delta variant have roughly 1,000 times more copies of the virus in their respiratory tract than those infected with the original strain of COVID-19. Those who are fully vaccinated are much less likely than those who are unvaccinated to contract and spread the Delta variant, but it does happen.

How do the COVID-19 Delta variants differ?

Research suggests that changes to the spike protein may make the Delta variant up to 50% more transmissible than other COVID-19 variants. For people who haven't had the coronavirus vaccine, the Delta variant may cause more severe illness than the original strain of the virus.

What is the risk of getting coronavirus on a plane?

Because of how air circulates and is filtered on airplanes, most viruses and other germs do not spread easily on airplanes. Although the risk of infection on an airplane is low, travelers should try to avoid contact with sick passengers and wash their hands often with soap and water for at least 20 seconds or use hand sanitizer that contain 60%–95% alcohol.
