The World Health Organisation (WHO) believe that symptoms of Omicron can develop between three and five days of infection. When are you most contagious?

What Is the Incubation Period for the Delta Variant?
The Delta variant, which evolved from previous strains of COVID-19, is currently the most dominant type of coronavirus in the U.S. The mutation allows the virus to produce a higher load of viral particles in the body. This makes the Delta variant more than 2 times as contagious as other variants. In fact, one study from China showed that in infections caused by the variant, the viral load was 1,000 times more than that of previous coronavirus strains.
How long does it take for a virus to spread?
Researchers estimate that people who get infected with the coronavirus can spread it to others 2 to 3 days before symptoms start and are most contagious 1 to 2 days before they feel sick.
How to know if you have a virus?
The CDC says that if you might have come into contact with the virus and have no symptoms, you should self-monitor. This means watching for signs such as fever, cough, and shortness of breath. Stay out of crowded places, keep at least 6 feet away from other people, and wear a cloth face mask when you have to go out.
What is the incubation period?
The incubation period is the number of days between when you’re infected with something and when you might see symptoms. Health care professionals and government officials use this number to decide how long people need to stay away from others during an outbreak. It’s different for every condition.

Omicron: A spike in COVID-19 cases and potentially different symptoms
First, some background. Omicron (or B.1.1.529) is a new coronavirus variant that was first identified in Botswana and South Africa in November—although later reports showed earlier cases in the Netherlands. The first case in the U.S. was reported on Dec. 1 in California. More cases have followed in at least 15 other states.
Do current vaccines protect against Omicron?
There is a third—and likely most important—question that has to do with how protective the existing vaccines will be against the new variant, says Dr. Murray.
What are scientists doing to prepare for Omicron?
The good news is that experts are in a better position to prepare for Omicron than they were a year ago, when Alpha, the first coronavirus variant to be identified, surfaced in Great Britain. “At that time, we didn’t have a very robust genomic surveillance system,” Grubaugh says. “Now, we have things in place.”
What you can do to protect yourself from Omicron
One thing people should do is stay calm, Grubaugh says, adding that the behind-the-scenes work to prepare for an Omicron worst-case scenario is necessary even if the variant turns out to be less of a threat than anyone anticipates. “The intent behind these preparations is not to scare people; it’s to do what we need to do to be prepared,” he says.
