Whooping cough spreading in Japan
Whooping cough is on the rise in Japan, with 775 cases reported already this year, health officials said.
The National Institute of Infectious Diseases said cases are up 30 percent from the same period last year, the Yomiuri Shimbun newspaper reported Tuesday.
The increased number of cases has been fueled by a growing number adults with whooping cough over the past decade. Last year 36.7 percent of whooping cough patients were aged 20 or over.
