The municipal Preventive Medicine Centre in Ho Chi Minh City has called on residents and concerned agencies to pay more attention to preventive measures as dengue fever enters its peak season.

Dr Nguyen Dac Tho, depuy head of the centre, said that fever usually peaks during November and December.

Since the beginning of this year, the city has recorded 5,799 patients with dengue fever, a decrease of 34 percent over the same period last year.

However, the fever has seen an upward trend in many districts over the last three weeks, Tho said.

Eight districts including Tan Phu, Binh Tan and Go Vap were seeing the highest incidence, he added.

In the last three weeks, the city saw 753 patients test positive for dengue fever.

The city's Paediatric Hospitals No.1 and 2 as well as the Hospital for Tropical Diseases have all reported an increase in the number of children diagnosed with the fever in recent weeks.

The Preventive Medicine Centre has asked its branches in all districts to strengthen observation and preventive measures including spraying areas of high incidence and high risk with chemical solutions to kill mosquitoes and mosquito larvae that carry the disease.

It also asked residents to take the initiative and maintain environmental hygiene in their living areas and to use mosquito nets when sleeping.-VNA
