A Vietnamese woman has been confirmed infected with the mosquito-borne Zika virus in the first case in Tokyo since the government recognized the disease as Class-4 in February, the health ministry said Monday.
It is also the 11th case in Japan since the first infection was confirmed here in 2013. None of the people contracted the disease in Japan.
After the woman, who is in her 40s, was stung by a mosquito in Vietnam, she experienced a headache and rashes on her body on Sept. 5 before coming to Japan last Thursday, health ministry official Shoji Miyagawa said.
