A new study conducted by Japanese researchers has shown that peak viral loads in people infected with omicron occur between 3 to 6 days after the onset of symptoms. Thats because omicron appears to cause symptoms faster than previous variants - about three days after infection, on average, according to preliminary studies. He has written for Scientific American about therapeutic viruses that can infect harmful bacteria and about dangerous contaminants in drinking water. In previous variants of COVID-19, people were contagious two to four days after they were first infected.

The CDC defines close contact as being less than 6 feet away from an infected person for a total of 15 minutes or more over a 24-hour period. The study, which was conducted by scientists in Beijing, found that with every new variant, COVIDs incubation time has decreased significantly. Scientists are now trying to model Omicrons global trajectory, which depends on two factors. One is its innate contagiousness, or transmissibility. The study stated that since the beginning of the COVID-19 [pandemic], [COVID] has evolved and mutated continuously, producing variants with different transmissibility.. all the variants have been descendants of omicron. COVID-19: When should you do a lateral flow test and when should you do a PCR?
