Apr 12 (thestar.com.my) - Japan, with its teams of Covid-19 "cluster busters" has gained a lot of very useful information, including that only one in five infected people spread the disease, the World Health Organization said on Friday (April 10).
"Japan has also seen cases of Covid-19 in three prefectures including Tokyo that are not linked to known chains of transmission," Michael Ryan, executive director of the WHO Health Emergencies Programme told a press conference.
"That is not good, but they are looking."
"The data I saw this morning reassures me they are very aggressively following this," he said. But Japan may have to scale up measures in some prefectures, he added.
