Just one day after the Tokyo metropolitan government shut down portions of Yoyogi Park due the dengue infected mosquitoes, health authorities now say at least one case is not linked to the popular park.
A Japan Times report today notes a man in his 30s in Saitama Prefecture presented with dengue symptoms over the weekend; however, he had not traveled abroad or visited Yoyogi Park recently. The ministry said it appears he was infected in nearby Shinjuku Chuo Park in Tokyo.
To date, 59 locally acquired dengue fever cases have been confirmed.
A teenage girl from Saitama Prefecture, which was reported last Wednesday, was the first locally acquired dengue case in Japan since 1945.
Dengue is transmitted by the bite of a mosquito infected with one of the four dengue virus serotypes. It is a febrile illness that affects infants, young children and adults with symptoms appearing 3-14 days after the infective bite.
Dengue is not transmitted directly from person-to-person and symptoms range from mild fever, to incapacitatinghigh fever, with severe headache, pain behind the eyes, muscle and joint pain, and rash. There is no vaccine or any specific medicine to treat dengue. People who have dengue fever should rest, drink plenty of fluids and reduce the fever using paracetamol or see a doctor.
