Is Sri Lanka prepared for yellow fever outbreaks? A case study

From Dec 5, 2015 to Oct 13, 2016, 4306 suspected cases of yellow fever were reported in Angola, with 369 deaths and an alarming case fatality ratio of 8·8%. Three countries: the Democratic Republic of the Congo, Kenya, and China, have reported imported cases from Angola. This is the first time yellow fever has been reported in Asia. Of the ten laboratory-confirmed yellow fever cases reported in China, six people reside in Fujian Province, an area where dengue transmission has occurred, raising concerns of autochthonous transmission. In response to global concerns about the spread of yellow fever and the first cases reported in Asia, we analysed the border health procedures pertaining to yellow fever vaccination and epidemiological surveillance, regulation, and control in Sri Lanka as a case study for other non-endemic countries, particularly those in Asia with an abundance of the vector Aedes aegypti.
