Flu spreading in Japan, doubling number of cases per hospital

Via The Mainichi Daily News :

" An influenza epidemic is spreading in Japan, doubling the number of cases per hospital, according to data compiled through Tuesday by the National Institute of Infectious Diseases.

Over 90 percent of the cases this flu season are due to the Hong Kong influenza A virus subtype H3N2, marking the first epidemic in five years of the seasonal flu virus that can cause encephalitis in infants and gravely affect elderly people, the institute said.

Data collected on a regular basis from around 5,000 medical institutions across Japan show that the average number of cases stood at 7.33 in the week through Jan. 15, up from 3.76 a week earlier.

The number of cases, which increased in all 47 prefectures, has since continued to grow, the institute added, referring to data from around 6,700 drugstores."
