There’s still a lot we don’t know about the omicron coronavirus variant, including whether it causes more severe COVID-19 or the degree to which it evades vaccines’ defenses in real-world settings.

But early data collected in London reveals the answer to a question we’re all asking: Does omicron cause different symptoms than delta and other variants?

Not quite, according to the ZOE COVID Study — an app some U.K. residents use to self-report information about their coronavirus vaccination and infections.

A comparison of data from thousands of people who tested positive for COVID-19 in October when the delta variant was dominant in London compared to December when omicron took over reveals “no clear difference in early symptoms (3 days after test).”

The top five reported symptoms in both periods, however, suggest the common cold you think you have may actually be COVID-19.
