And research recently showed a new difference between the two mutants, which is the “viral incubation period”, which is the length of time between being exposed to the virus and when symptoms start appearing.
A small study by the Centers for Disease Control found that the Omicron nursery appears to be about a day shorter than the Delta nursery.
With Delta, the incubation time was usually about 4 days, while with Omicron, the period was shortened to 3 days, according to “Fox News”.
Why is the incubation period of the virus important?
The incubation period of the virus is one of the factors that can contribute to its rapid spread, as the short incubation period means that the person’s exposure to the virus and its ability to transmit it to others is very fast.
“With Omicron, most transmission occurs within 1 to 2 days before symptoms appear, and within 2 to 3 days afterwards,” Harvard Medical School wrote.
She added, “Wearing masks can help reduce the risk of infection, especially from someone who has not yet shown symptoms.”
According to studies, people who have tested positive for Omicron’s symptoms should also stay at home, and isolate from others.
