The Foreign Office has warned tourists visiting Japan to protect themselves against mosquitoes as cases of dengue fever are traced to Tokyo’s parks.
Japan’s health ministry has confirmed that 11 more people have been infected with the virus after visiting Yoyogi Park.
This brings the total count of people infected with dengue in the country to 47 since August 27, according to the Telegraph.
The park has since been closed.
The Foreign Office said: "Recently confirmed cases of dengue fever have been linked to mosquitoes in Tokyo parks. You should take suitable steps to avoid being bitten by mosquitoes."
Dengue is a tropical disease for which there is no effective vaccine yet. Symptoms are the onset of a sudden fever, headache, muscle pain, rashes and, in extreme cases, the disease can cause severe bleeding that can be life-threatening.
