As Japan nears the planned end of its third state of emergency, infectious disease experts warn that a fourth declaration in Tokyo could be right around the corner.

A team of scientists led by Hiroshi Nishiura, a member of the health ministry’s expert panel on the coronavirus, projected that a fourth state of emergency in the capital may become necessary in August if the current emergency is lifted on June 20.

Nishiura, an epidemiologist from Kyoto University, submitted the report during a panel meeting on Wednesday.
