I think it was August 13th when they reported the effectives of IVM and then held a press conference on Aug 22 about it. So it’s only been a few weeks. Watch that line continue to head straight down like every other country that uses it.
Thanks, the comment implied the August 13 use date (but there is no explanation of the time lag between Tokyo and Osaka), but it’s not explicit. For all I know, the Japan AMA could have recommended ivermectin use on August 13th, but no one listened.
Hopefully they did adopt its use, and the future graphs will be clearer (e.g., including a line where ivermectin use was adopted on a wide scale).
