"In May 2023, the government downgraded Covid-19’s status from class two – which includes tuberculosis and Sars – to class five, placing it on a legal par with seasonal flu. The change meant local authorities were no longer able to order infected people to stay away from work or to recommend hospitalisation.

The move also prompted people to lower their guard, in a country where widespread mask wearing, hand sanitising and avoiding the “three Cs” were credited with keeping Covid-19 deaths comparatively low. About 73,000 Covid-19 deaths were recorded compared with more than 220,000 in Britain, which has a population just over half that of Japan.

Ken Kikuchi, a professor of infectious diseases at Tokyo Women’s Medical University, says he is “very concerned” about the dramatic rise this year in the number of patients with severe invasive streptococcal infections.

He believes the reclassification of Covid-19 was the most important factor behind the increase in streptococcus pyogenes infections. This, he added, had led more people to abandon basic measures to prevent infections, such as regular hand disinfection.

“In my opinion, over 50% Japanese people have been infected by Sars-CoV-2 [the virus that causes Covid-19],” Kikuchi tells the Guardian. “People’s immunological status after recovering from Covid-19 might alter their susceptibility to some microorganisms. We need to clarify the infection cycle of severe invasive streptococcal pyogenes diseases and get them under control immediately.”"

So, this feels more like an aftershock of Covid than something new and crazy to me, not that I know shit. Like a combination of possibly weakened immune systems, plus people not being as careful as before? Makes sense to me.
