Thai health officials are warning the public of the mosquito borne viral disease, dengue fever, as cases of the disease have picked up significantly this summer.
According to Thailand news sources, last week, 3,303 people were reportedly infected by the virus, three of whom died, one each from Pathum Thani, Ratchaburi and Petchaburi provinces; which brings this year’s total number of infections to 42,900 and 35 deaths.
Five provinces: Rayong, Trad, Petchaburi, Tak and Ang Thong, are the areas where the disease mostly reportedly spread, said the Department.
During the first six months of 2015 (Jan-June), health officials reported a total of 14591 cases from 77 provinces, including 1 death.
Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, A. albopictus.
The World Health Organization says there are 4 distinct, but closely related, serotypes of the virus that causedengue (DEN-1, DEN-2, DEN-3 and DEN-4). Recovery from infection by one provides lifelong immunity against that particular serotype.
However, cross-immunity to the other serotypes after recovery is only partial and temporary. Subsequent infections by other serotypes increase the risk of developing severe dengue.
