Covid-19: Omicron is 40% deadlier than seasonal flu, study finds

Countries around the world have been relaxing mitigation measures, from mask mandates to testing requirements, and pushing for a return to normal life.

The omicron strain of Covid-19 is at least 40% more lethal than seasonal flu, according Japanese scientists, underscoring the potential danger of lifting pandemic curbs too quickly and underestimating the virus’s ongoing health risks. 
 

The case fatality rate of omicron in Japan, based on cumulative excess deaths and the number of infections since January, was about 0.13%, according to an analysis by scientists who advise the country’s health minister. While that is significantly lower than the 4.25% case fatality rate from earlier in the outbreak, it’s still higher than the 0.006% to 0.09% seen with seasonal flu, they said.
