WASHINGTON / LONDON -- Some countries have begun to shorten the isolation period for people who have had close contact with those infected with the omicron variant of the novel coronavirus.
The U.S. Centers for Disease Control and Prevention released a new guideline late last year that recommends shortening the isolation period of close contacts from 10 days to five days.
The CDC said the virus is typically transmitted from an infected person to others in a period that runs from one or two days before the newly infected person shows symptoms to two or three days afterward.
