Vietnam has seen in excess of 50,000 dengue fever cases in 2017 to date, including 15 deaths and the capital city of Hanoi has been struck hard in recent weeks by the mosquito borne viral disease, according the Strait Times.


The report notes that in just the past week, 1,100 cases have been reported, citing local health officials. Hanoi has seen 5,300 cases year to date.

Hospital director Nguyen Van Kinh told reporters that doctors are concerned about the unusually high number of deaths caused by brain hemorrhages. Five patients have already died from the condition so far this year, compared to only one or two in previous years.

Local doctors said the key reason for the surge in dengue fever infections is the early coming of rainy season which has created favorable conditions for mosquitoes to breed and grow quickly.
