The omicron variant of Covid-19 appears less likely than delta to lead to long Covid, according to British researchers.
But because omicron is much more contagious than previous variants, the enormous number of people who have been infected since it began spreading in the winter means there will still be many who are struggling with long-lasting symptoms, such as brain fog, headaches and debilitating fatigue.
The new research, which was published Thursday in The Lancet, is an observational analysis of people who signed up for a smartphone app-led project called the ZOE Covid Study. Users regularly report any Covid symptoms, vaccination status and other demographic information.
