There have been 9 deaths, most of them in the southern provinces, including Ca Mau, An Giang, and Tra Vinh provinces.
The main cause is the hesitation to go to hospitals when patients experienced initial symptoms, thus leading to serious complications such as gastrointestinal bleeding, liver failure, and heart failure. Compared with last year, the number of cases of dengue fever decreased by 30-40%, but the number of severe cases increased sharply. According to experts, dengue fever cases increased from April, three months earlier than any other year. At the peak of the rainy season from now until October 11th, dengue fever will peak and may lead to outbreaks.
