Jakarta, CNBC Indonesia – The incubation period for the Omicron variant of Covid-19 occurs within three days. Then when is the right time for a PCR test?
In the isolation and quarantine guidelines made by the US Centers for Disease Control and Prevention (CDC), it shows that transmission of Covid-19 often occurs 1-2 days before the onset of symptoms and for 2-3 days after.
“This has something to do with the CDC data which really shows after 7 days there is almost no risk of transmission at this point,” said Dr. Allison Arwady, Commissioner of the Chicago Department of Public Health, quoted from NBC ChicagoTuesday (12/7/2022).

Arwady further explained, within a period of 5-7 days it depends on whether people have been vaccinated and the underlying conditions. But the risk seems to drop a lot and combined with the mask, the risk is very low.
According to the CDC, anyone who may have been exposed to Covid should have a PCR swab test five days after exposure. In addition, the test is carried out after the appearance of symptoms.
“If symptoms do occur, the individual should be immediately quarantined until a negative test confirms the symptoms are not caused by Covid-19,” the CDC guidelines state.
This incubation time turned out to be much shorter than Delta or the initial variant. NY Times citing a CDC study reporting early variants had a median incubation period of about five days and four days for Delta.
NY Times also report problems viral load various variants of Covid-19. Viral load is the amount of virus that accumulates in a person’s body and is considered the most contagious when viral loadIt’s high.
In one study, the Alpha and Delta variants found peaks of viral load about three days after the virus is first detected and clears the virus about six days. As for the Omicron variant, it remains to be seen further.
However, according to another preliminary study, Omicron infection occurred one day shorter than Delta infection and resulted in a slightly lower peak viral load. In another study, between people who were vaccinated and booster, Omicron and Delta produced similar levels of infectious virus.
