Da Nang (VNA) – Residents in the central city of Da Nang should intensify measures against dengue fever as the rainy season has started, encouraging mosquito populations to grow, said a local doctor.

Doctor Nguyen Tam Lam from the municipal Preventive Health Centre said 1,447 cases of dengue had been recorded in the city so far this year, down more than 65 percent over the same period last year.

However, from August 6-12, Da Nang reported 88 cases, 12 cases more than the previous week, mostly in Lien Chieu, Thanh Khe and Hai Chau districts, according to the doctor.

The Preventive Health Centre has coordinated with medical teams in the districts to handle dengue hotspots, Lam said, adding that apart from spraying mosquito repellent, the local medical sector has intensified the information work to raise public awareness of the fight against the epidemic.  

Dengue fever is an acute viral disease spread by two kinds of mosquitoes – Aedes Aegypti and Aedes Albopictus, with no specific vaccine and treatment established to date. 

The disease is common in tropical countries. In Vietnam, peak season of the disease lasts from July to October. As the virus is divided into four types – D1, D2, D3 and D4, a person can be infected many times.

Vietnam experienced a boom of dengue fever in 2017 when 181,054 infection cases and 30 deaths were reported in almost all localities.-VNA
