The Malaysian Ministry of Health announced today, Friday, that it had detected a sharp rise in cases of dengue fever in the capital, Kuala Lumpur, and the surrounding Klang Valley region, and warned of an increase in the chances of transmission of the infection with the increase in cases of this disease, which is transmitted by mosquitoes to other areas of the country.
The ministry indicated, in a statement, that the increase in the number of cases was mainly concentrated in the early stages in the Klang Valley region, especially Kuala Lumpur, Putrajaya and Selangor state.
58,079 cases have been recorded since early August, an increase of 56.2%. for the same period in 2025, with 55 deaths due to complications from dengue fever.
In Kuala Lumpur and Putrajaya, cases jumped by 106%. While the state of Selangor saw an increase of 61%, compared to the same period last year.
The Ministry explained that it has taken intensive and targeted prevention and control measures, including early detection of cases and control of disease vectors, which have begun to yield positive results.
However, she stated that the risk of dengue fever remains high, and that the national situation is worrying in light of the rising number of cases in other states.
According to the Ministry, “The increase in cases of dengue fever is the result of several factors, including unexpected weather conditions, especially rainfall accompanied by hot weather, which creates a favorable environment for the breeding of Aedes mosquitoes,” stressing that it will continue to closely monitor the situation and will adjust its procedures based on developments.
The virus, which is transmitted by the Aedes aegypti mosquito, causes severe fever, headache, skin rash, and muscle and joint pain. Severe cases of infection can lead to hemorrhagic fever, and there is no vaccine against it.
