Omicron symptoms range from sore throat and body aches to fever and cough. But how quickly those symptoms appear seems to be different from the earlier versions of COVID-19.
While research is in the early phases, it appears that omicron is not only more contagious it infects people quicker with a shorter incubation period.
People who develop symptoms from the original strain of COVID-19 typically got them five to six days after contracting the virus, though incubation periods as long as 14 days have been reported. Other COVID-19 variants, such as the delta variant, had an incubation period of four days.
But in the case of omicron, the incubation period is much shorter- just three days, according to studies by the Centers for Disease Control and Prevention. People are generally contagious one to two days before symptoms appear and two-to-three days after they appear.
Omicron symptoms appear different than traditional COVID. Loss of smell and taste aren’t reported by many patients but symptoms such as congestion or runny nose, cough, fatigue, muscle and body aches, sore throat, headache, sweats appear to be more common.
According to the CDC, people with COVID-19 should isolate for five days after their symptoms subside and their fever has been gone for at least 24 hours without fever-reducing medication. After that, the CDC advises people to wear a mask around others for an additional five days to cut the risk of infecting others.
