The health ministry said Tuesday it has confirmed three more cases of infection with a tick-borne virus, bringing the total number of victims of the viral infection in the country to eight.
The three patients were infected with the virus, which causes severe fever with thrombocytopenia syndrome, or SFTS, between 2005 and 2012, but have since recovered, according to the ministry.
Among them, a woman in her 80s in Kochi Prefecture developed the disease last April. A man in his 80s in Saga Prefecture caught it in August 2010, as did a man in his 50s in Nagasaki Prefecture in November 2005.
Beginning this month, if SFTS cases, including suspected ones, are detected, doctors are required to file reports with public health centers.
Five suspected cases await checks for infection.
