Sri Lanka recorded over than 6,000 dengue cases in the first three weeks of January 2023 after a spell of heavy monsoon rain though a drop in cases is likely from February, officials said.
Health officials identified 6,204 dengue patients by January 22, up from 5,793 recorded in the corresponding period last year.
“A rise in cases can be observed in the November-January period with the heavy rain due to the northeast monsoon,” an official from the National Dengue Control Unit told EconomyNext.
Of all reported cases, 46.3 percent were from the Western Province, official reports showed.
Akuressa, Batticaloa, Eravur, Trincomalee, Madampe, Badulla, Eheliyagoda, Kegalle, Kalmunai North and Alayadivembu MOH areas were identified as high-risk areas for dengue during the third week of January by the health officials.
“We are expecting a decline in dengue cases soon. The Western province is always in the top position with the highest number of dengue cases. Apart from that, we are seeing a higher number of cases during this period in areas like Puttalam, Jaffna districts. A certain number of cases have also been recorded in the Kandy district,” the official said.
“Usually the cases peak in December, but they decline by February. This year, too, we are facing this scenario. There is an increase of dengue during the months of November, December and January”.
Due to the economic situation in the country, the Public Health Inspectors (PHIs) in an earlier report said, diesel and pesticides are not being provided by the ministry.
However, rejecting the allegation, the official from the NDCU said the government has provided enough funds for get the necessary pesticides but it is being used according to a scientific method to avoid building a resistance in the dengue mosquito.
“The recommendation is to do the fogging if there is a dengue outbreak or if there are few patients reported from the same locality.
“If you use this pesticide haphazardly, the mosquitos will develop resistance against it,” the official said, adding that there are adequate stocks of the chemical available.
