The good news is that long Covid is far less likely to occur after Omicron infection.
The ZOE researchers discovered 56,003 adult cases in the UK that initially tested positive between December 20, 2021, and March 9, 2022, when Omicron was the prevalent strain. These cases were found in the ZOE Health Study app.
When the Delta variant was prevalent, between June 1 and November 27, 2021, 41,361 instances that first tested positive were compared to these cases.
The researchers adjusted for sex, IMD (Index of Multiple Deprivation), age, the presence of comorbidities, vaccination status (one, two, or three doses), and body-mass index, all of which are associated with the risk of long Covid, in order to determine the relationship between long Covid and the infection period.
