Associated Press, Fri November 24, 2006 08:40 COLOMBO, Sri Lanka (AP) _ Sri Lanka's health officials on Friday confirmed an outbreak of chikungunya, a mosquito-borne fever.
Blood samples sent to Thai and Indian research institutes and three local laboratories tested positive for chikungunya, the Health Ministry's epidemiologist Nihal Abeysinghe said, adding that at least 50 people have been found to be carrying the illness.
Chikungunya _ like dengue _ is spread by female aedes mosquitoes, and symptoms include high fever, severe joint pains, headache and vomiting. There is no known cure for either disease.
Eighty-one people were reported dead after contracting chikungunya in South India in the past month, but health experts say the disease only weakens the immune system, allowing people to succumb to other ailments.
While the government has asked people not to panic, the independent Daily Mirror newspaper reported on Friday that a school in northwestern Kalpitiya was closed after many students and teachers were found with high fever.
Sri Lanka's Health Minister Nimal Siripala de Silva, meanwhile, asked public to prevent the spread of both the diseases by cleaning up areas where mosquitoes breed.
Mosquito-borne diseases usually spread with annual monsoons as the rains leave puddles of stagnant water for the insects to breed in.
``With the ongoing rains, such diseases could reach an epidemic proportion by next month unless drastic measures are taken to clean the environment,'' said Pradeep Kariyawasam, who heads the capital Colombo's health department
