Hanoi (VNA) - Dengue fever cases are on the rise in Hanoi, as weather has been favourable to the development of infected mosquitoes.

Statistics from the Hanoi Health Department show that 1,281 cases of dengue fever were recorded in the city by June 4, 2.6 times more than the same period last year.

Of these, 126 patients are receiving treatment at hospitals and one person has reportedly died in Dong Da district’s Trung Liệt ward.

Districts of Dong Da, Hoang Mai, Hai Ba Trung and Thanh Xuan have reported the highest number of dengue cases.

The number of dengue-infected patients tends to rise from mid of April and increase rapidly in early June. The weather turns to more dangerous with more heat waves and heavy rains, creating optimal conditions for mosquitoes to reproduce.

Hoang Duc Hanh, deputy director of Hanoi’s Department of Health, said the department has directed medical units to strengthen the implementation of measures to prevent the disease, particularly providing information on the epidemic situation to locals and guiding them on how to prevent the disease.

The department will take drastic measures to stop the spreading of dengue fever cases, as September and November are high season for the disease.
