After the floods, the weather is now sunny, creating favorable conditions for disease-carrying mosquitoes to breed. Monitoring results at some outbreak areas still show insect numbers exceeding the risk threshold, and the number of cases is forecast to continue to increase in the coming time.
Associate Professor, Dr. Tran Dac Phu, former Director of the Department of Preventive Medicine, Ministry of Health said that after floods, the diseases with the highest risk are diarrhea, pink eye, respiratory tract infections, flu, infectious diseases...
A humid, polluted environment is a favorable condition for mosquitoes to develop, so dengue fever is very likely to occur. On the other hand, after floods, diseases caused by disease vectors develop strongly. These are diseases that are very contagious and can cause widespread outbreaks. A typical example of this is dengue fever.
Right in Hanoi, according to the Hanoi Center for Disease Control (CDC), last week (from September 6 to September 13), the entire city recorded 227 cases of dengue fever, an increase of 37 cases compared to the previous week.
Hanoi CDC assessed that dengue fever has now entered its peak period (September to November), with complex and unpredictable weather conditions combined with heavy rain creating favorable conditions for the reproduction and development of disease-carrying mosquitoes. At the same time, monitoring results at some outbreak areas still recorded insect indexes exceeding the risk threshold, predicting that the number of dengue fever cases will continue to increase in the coming time.
Dengue fever will continue to increase in the near future if there are no effective control and prevention measures. In addition to the causes of recent floods, climate change, the earth tends to get warmer while the mosquito that causes dengue fever "prefers" hot and humid climates.
Dengue fever occurs year-round, but the number of cases often increases during the rainy season. In the South, the disease begins to increase in June, increases sharply in August, and according to forecasts this year, the peak of dengue fever will fall in October.
The Ministry of Health has requested the maintenance of mobile anti-epidemic teams, supporting lower-level units in monitoring and handling epidemics and infectious diseases after storms and floods. After receiving a request from Son La province, the Ministry of Health decided to provide the provincial Department of Health with 3,000 barrels of Cloramin B from the disaster prevention warehouse, totaling 75,000 kg, to disinfect water sources.
