Re: Nongprue targets mosquitoes in Khao Talo (PM Friday, 31 July 2015) – Yellow fever is spread by the same species of mosquito as dengue, and is much more dangerous (case fatality rate 20%). The public would do well to ask their health authority if Bangkok has a national contingency plan to respond in case of the importation of a case of yellow fever that could spread much worse than Ebola did in Nigeria from a single imported case.
