Dengue cases double in Hanoi as nationwide infections climb
VOV.VN - Dengue fever cases in the capital city of Hanoi have doubled in the past week, raising concerns of a broader outbreak as Vietnam enters peak transmission season.
According to the Hanoi Centre for Disease Control (CDC Hanoi), the capital recorded 72 cases of dengue fever across 38 out of 126 wards and communes between July 18 and 25, doubling the number reported the previous week.
Since the beginning of the year, Hanoi has confirmed 475 cases in 100 out of 126 wards and communes, with 15 outbreak clusters identified, seven of which are still active.
The number of dengue infections has decreased significantly compared to the same period in 2024, said CDC Hanoi, adding the capital has not recorded any dengue-related deaths.
However, the centre warned that transmission is on the rise. Mosquito density at several clusters remains at a high-risk threshold, prompting calls for vigilance and community action.
Elsewhere, as of July 15 Ho Chi Minh City has recorded 15,546 cases of dengue fever, a 157% increase compared to the same period from 2024, including 10 deaths, reported the Ho Chi Minh City Centre for Disease Control (HCDC).
In the former Ba Ria–Vung Tau province, now part of expanded Ho Chi Minh City, 172 outbreak clusters have been detected, with 21 new ones emerging within the last two weeks alone.
Nationally, over 32,000 dengue cases have been recorded as of early July, with numbers expected to rise as the country moves deeper into the rainy season, particularly in the north and south, where humid and wet conditions create ideal breeding grounds for mosquitoes.
Meanwhile, other infectious diseases are also on the rise in Hanoi. The past week saw 88 new cases of hand, foot and mouth disease (HFMD) documented, bringing the 2025 total to 3,293, almost double the number from 2024. Most cases remain isolated; and no complex outbreaks have been detected.
The city also reported 28 new cases of measles last week, raising its 2025 total to 4,295, including a fatality. Notably, the highest incidence was seen in children aged 1-5 years, up more than 20%.
