Dengue fever is a mosquito infectious disease. Understanding the transmission route of dengue fever is of great significance to prevent the disease. Dengue fever occurs frequently in summer, mainly because the transmission vector of the disease is mosquitoes, which are usually caused by the bite of infected mosquitoes. Let's take a look at what dengue fever is, what its transmission routes are and how to prevent dengue fever.
1。 What is dengue fever?
Dengue fever is an acute infectious disease transmitted by mosquito bites. There are two kinds of mosquitoes: Aedes aegypti and Aedes albopictus (commonly known as piezomosquitoes). The disease is mostly prevalent in tropical and subtropical areas where mosquitoes are common. Guangdong, Guangdong and Hainan are also high incidence areas of dengue fever.
Dengue fever usually occurs rapidly, with symptoms such as high fever, headache, severe soreness of muscles, bones and joints, and even some patients have other symptoms such as skin rash.
2。 Transmission route of dengue fever
Aedes albopictus female mosquitoes are the main vector of transmission. Mosquitoes bite dengue virus carriers and suck the blood with the virus. The virus can survive in mosquitoes for up to 30 days or even longer. Therefore, the virus will reproduce in mosquitoes and then bite healthy people, so as to spread the virus.
In other words, although dengue fever is an infectious disease, it will not spread directly between people. If it is not enough, it can not be taken lightly. There are many mosquitoes in summer. If there are dengue carriers in the surrounding population, the probability of dengue fever infection is very high.
3。 How to prevent dengue fever
① Stay away from epidemic areas
Dengue fever usually has a certain epidemic area when it is found. The epidemic area of dengue fever should be well monitored, and the people should avoid appearing in these areas or staying for a long time.
② Mosquito control is necessary to prevent dengue fever
Mosquitoes are the only known vector of dengue fever. Therefore, if you want to prevent dengue fever, you can start with killing mosquitoes. Places with accumulated water in the home, such as water tanks and flower pots, are places where mosquitoes breed. Pay attention to cleaning and handling these places to eliminate mosquitoes.
③ Prevent mosquito bites
Aedes mosquitoes that spread the virus like to move during the day. Therefore, when you go out, wearing long clothes and trousers and applying mosquito repellent products on your bare skin can effectively prevent mosquito bites and dengue fever from the root.
