But rocketing case numbers are forcing more and more people to self-isolate and driving up hospitalisations, putting strain on health services. Studies have measured the concentration of live (and therefore contagious) virus in the noses of infected people and how levels change over time. In some people, genetic remnants can linger in the nose for weeks or even months after the virus is no longer able to cause infections, Weatherhead says. People who are unvaccinated should adhere to this rule since they are more likely to become infected and spread the virus. Studies show that COVID-19 vaccines can greatly reduce your chances of getting infected with the virus.
