Two more people were reported to have contracted dengue fever in Japan on Thursday, a day after the government said it had confirmed the first local infection of the disease in nearly 70 years.
A man in Tokyo and a woman from Saitama Prefecture, both in their 20s, and the first patient — a teenage girl also from Saitama — go to the same school in Tokyo and are believed to have been infected after being bitten by mosquitoes in Yoyogi Park in central Tokyo.
The three went to the park about three times a week from early August with other students to rehearse for a school festival.
The Tokyo metropolitan government is trying to eradicate mosquitoes in the park.
Around 200 Japanese are infected with the disease annually while traveling overseas, but no domestic infection had been confirmed since 1945, according to the health ministry.
