Washington: It will be possible to forecast the outbreak of dengue fever up to 16 weeks in advance, with the help of a warning system which measures the risk of dengue incidence using precipitation and air temperature.This is what Yien Ling Hii concludes in the dissertation she is defending at Umea University on 3 May.Dengue fever is an infectious disease caused by virus and transmitted to persons by mosquitoes. A person contracted dengue fever usually shows symptoms including sudden spike of high fever, muscle ache, joint pain, rashes, and headache.An infected person normally recovers within a few weeks, but a small per cent of patients can develop fatal complications such as plasma leakage, severe bleeding, and severe organ impairments which can lead to death.To date, there is no drug for treatment or vaccines to protect against dengue fever. Therefore, the most effective way to prevent dengue is to control the mosquito population.
