UNITED NATIONS - The United Nations has joined Pakistans efforts to respond to the dengue fever epidemic that has affected more than 12,000 people and resulted in 125 deaths, the World Health Organisation said Friday. The organisation is supporting sub-groups, which have been formed by the Pakistani authorities to respond to the epidemic through case management, community mobilisation, vector control and public awareness campaigns, WHO spokesperson Tarek Jasarevic told reporters in Geneva. According to a press release, he said the WHO has also been facilitating and supporting dengue case management training at the district level in several provinces. A WHO expert on the disease landed at the country last week to provide technical guidance on dengue fever control. A dengue fever booklet for teachers has been printed and is being circulated. The WHO has also circulated new clinical case management guidelines drafted by Pakistani doctors on the basis of a retrospective study of Pakistani hospital data and global and regional experiences. Last year, 11,024 confirmed cases of dengue fever and 40 deaths were reported in Pakistan, but this year the number of cases has climbed to 12,466, mostly in Punjab.
