However, the incubation period of Omicron and its branches is believed to be much shorter – 3-5 days.

Dr. Allison Arwadi, Commissioner of the Chicago Public Health Service, told NBC:

“The time between someone’s exposure to Covid and the possibility of causing an infection is shorter. The time it takes for a symptom to develop is shorter, the time that someone can be infected is shorter, and much more. For humans, the time it takes to recover is also shorter, often because more people are vaccinated. “

Finding and amplifying some of the viral genetic material (RNA in the case of Covid-19) in the body. A PCR test that is extremely sensitive and can detect that there are few viral fragments. This is a PCR test that allows the viral RNA fragment to remain in our body after the infection has ended and the virus has been removed from the system. Because there is a possibility. “

Professor Tim Spector, Principal Scientist for the ZoeCovid-19 Symptoms Tracker App, said on Twitter:

“Unfortunately, it’s out of order, but this is the beginning and can help reduce infections. Thanks to Zoe Logger!”

He previously criticized the government’s refusal to expand the list of symptoms, saying last month:
