According to the Hanoi Department of Health, the situation of dengue fever is showing signs of sudden increase and shows no sign of stopping. Usually, dengue fever outbreak occurs from about June to August. However, right from March this year, the number of dengue fever cases has increased rapidly.
1. What is Dengue hemorrhagic fever?
Dengue hemorrhagic fever is an acute viral infection transmitted by mosquitoes. The first case of dengue was recorded in the 18th century. However, the number of new cases has continuously increased over the past 50 years.Dengue hemorrhagic fever is one of the diseases listed by the World Health Organization (WHO) as a group of dangerous infectious diseases that need top attention. Up to now, the disease has occurred in more than 100 countries, with the total number of cases recorded each year in the range of 50-100 thousand cases. The disease is more common in Asian countries and is considered one of the leading causes of hospitalization and even death.
In terms of pathophysiology, Dengue hemorrhagic fever is divided into 3 stages: incubation period, dengue phase and recovery phase. The incubation period of dengue fever depends on the body's resistance to the causative agent. When the body is no longer able to fight back, the disease begins to show more obvious symptoms.

Up to the present time, there is no specific treatment or vaccine for dengue fever. Therefore, proactively learning about the transmission routes of dengue fever and disease prevention is still the most effective measure in reducing the risk of dengue virus transmission in the community.
2. The possibility of an outbreak of dengue fever at the end of March 2019
Usually, the period from June to August every year is when the dengue fever epidemic appears. The peak of the epidemic usually falls around September - November. However, this year the epidemic has tended to increase sharply since March.
According to the Hanoi Center for Disease Control, although this year is not the forecasted year. There is a pandemic due to the dengue virus, but the number of dengue fever cases is still very high. The reason is that the weather conditions are favorable for mosquitoes to transmit diseases and viruses to exist and develop.
Specifically, the El Nino phenomenon appeared, leading to the average temperature reaching higher than every year, starting from February and is forecasted to last until June 2019. This unusual weather phenomenon occurs nationwide, causing light rain and drizzle for many days, creating stagnant water, which is a condition for mosquitoes to breed and develop larvae. Therefore, insect surveillance and vector control of Dengue hemorrhagic fever need to be strengthened and implemented appropriately.
Dengue fever is often concentrated in densely populated areas, such as labor quarters, housing areas where many workers, workers and students are rented. Therefore, dengue fever prevention is still an important task that needs to be quickly implemented in localities.
