COLOMBO, Aug. 5 (Xinhua) -- Forty seven people died and over 200,000 were infected by the dengue virus across Sri Lanka in the first seven months this year, the government information department quoted the Epidemiology Unit as saying on Monday.
Till the end of July, a total of 234,078 dengue cases were reported, with the highest number of cases reported from the Colombo district with 7,260 cases, over 3,000 Gampaha on the outskirts of Colombo and over 2,000 in Kalutara.
The Epidemiology Unit said it had identified five high-risk districts, including Colombo, Gampaha, Galle, Kalutara in the Western Province and Ratnapura in south central Sri Lanka.
Medical experts have urged people to seek immediate medical attention if they suffered from high fever, uncontrolled vomiting, abdominal pain, dizziness and reduced urinary.
"All fever patients need rest and should refrain from attending work or school," said epidemiologists. "Dengue Hemorrhagic Fever (DHF) can be fatal."
Medical experts have further urged pregnant women to seek hospital admission immediately on the first day of fever.
Last year, over 50 people died and over 48,000 were affected by the mosquito-borne virus in Sri Lanka, with the National Dengue Control Unit launching several programs to eradicate mosquito's breeding grounds in several districts of the island country.
