Localities are intensifying measures to prevent dengue fever and Zika virus. According to the Ministry of Health, the dengue infections dropped by 20 percent in the first months of 2017. However, at present, the disease is increasing in some cities and provinces such as Da Nang, Quang Nam, Quang Ngai, Binh Thuan, Thua Thien-Hue, Ba Ria-Vung Tau, Binh Duong, Bac Lieu, Ca Mau, Tra Vinh, Vinh Long, Hau Giang and Dak Lak. The country has recorded several Zika cases in some cities and provinces in the south where the rainy season is creating favourable conditions for mosquitoes to develop. Given the fact, the health ministry has requested the centrally-run provincial and municipal People’s Committees to direct departments, organisations and people to actively eliminate mosquito larva to prevent the spread of the diseases.
