The string of extremely hot days has apparently reduced the number of mosquitoes carrying Japanese encephalitis by over 70 percent.
The Korea Centers for Disease Control and Prevention says the number of this particular breed of small, dark brown mosquitoes is down 71-point-four percent compared to last year.
Japanese encephalitis is not common in modern Korea, but it can be fatal and there are usually a couple of dozen cases a year.
The number of mosquitoes in general also dropped by two-point-two percent.
The KCDC says there are fewer of the pests because of the extreme heat and the short monsoon.
