Do mosquitoes transmit diseases? Do mosquitoes transmit diseases?

Japanese encephalitis is transmitted by mosquitoes.

Mosquito bites and harass people's rest and work, which is very disgusting. However, the most serious harm of mosquitoes to humans is that they can transmit a variety of infectious diseases, which we must pay attention to and pay attention to prevention.

In urban Shanghai, a common mosquito-borne disease is Japanese encephalitis. JE is more common in children under 10 years of age. Generally, the onset is acute, and the clinical manifestations are sudden fever, nausea, vomiting, drowsiness, and headache.

2 After 3 days, coma, convulsions, and stiff neck appear, and death can occur if not rescued in time. A small number of people can have sequelae such as mental retardation, stiffness of hands and feet, inability to move, etc., and in severe cases, become lifelong disabilities.

Mosquito-borne malaria has also occurred in Shanghai. When a mosquito bites a malaria person and then bites a normal person, it is contagious. Malaria, commonly known as "swing" and "cold and fever", mostly occurs in summer and autumn, and most of the patients suddenly have chills, shivering, paleness, and purple lips and nails.

The chills stopped and then followed by a high fever and headache, followed by profuse sweating all over the body, and the body temperature returned to normal. Symptoms may occur one to two days apart. Malaria symptoms are typical and easy to diagnose, but due to the destruction of a large number of red blood cells by the malaria parasite, multiple episodes can cause anemia, hepatosplenomegaly, which seriously affects health, and can also lead to miscarriage or stillbirth in pregnant women.

Aedes mosquitoes, which transmits malaria, also transmits dengue fever. It is endemic in Guangdong, China, and Southeast Asia, and is prone to occur in late summer and early autumn, with high fever and severe headache as the main symptoms. Dengue fever spreads rapidly and has a high incidence but a low case fatality rate.

Shanghai residents should check whether there is an epidemic in the local area in advance when traveling to the hot southern regions for business or tourism.

Yellow fever is transmitted by the Aedes aegypti mosquito and is mainly endemic in South America and Africa, and there have been reports of deaths from the disease in Shanghai after returning from Africa. Therefore, Shanghai Customs should strengthen the quarantine of personnel from epidemic areas.

Mosquito-borne filariasis is widely distributed in China, and it is rare in Shanghai. Filariasis larvae can be transferred from sick people to healthy people through mosquito bites, and then parasitize the human lymphatic system, producing symptoms of lymphangitis. The main manifestation is a stretched red line from top to bottom on the limb, with a tenderness sensation.

Patients also have chills, headaches, and periodic episodes of high fever. Patients with advanced filaria have rubber swelling on the lower limbs, which are rough, thickened, hardened, and the affected limbs are obviously coarse and swollen.

Among the major mosquito-borne diseases, Japanese encephalitis and yellow fever can be immunized with vaccination. Malaria can be prevented by taking pyrimethamine. There is no effective prevention of dengue fever and filariasis.

The harm of mosquitoes to the human body is serious. Strengthening mosquito prevention and eradication and improving the working and living environment are important measures to prevent mosquito-borne infectious diseases in mosquito-infested seasons and areas.

Yes! So mosquitoes are the four pests!

Being bitten by a mosquito is not just a pimple, more than 80 diseases such as malaria and dengue fever are transmitted by mosquitoes.

Mosquitoes that can transmit diseases in China can be roughly divided into three categories: one is called Anopheles mosquitoes, commonly known as malaria mosquitoes, which mainly transmit malaria. According to incomplete statistics, in 1929, about 2 million people died of malaria worldwide within one year.

The other group is called Culex mosquitoes, which mainly transmit filariasis and Japanese encephalitis. The third group is called Aedes mosquito, which has black and white markings on its body, also known as black spots, and mainly transmits Japanese encephalitis and dengue fever.

It will not be high that the main hazard of mosquitoes is to spread diseases. According to research, there are more than 80 diseases transmitted by mosquitoes.

Malaria is a disease transmitted by the Anopheles mosquito.

Japanese encephalitis, an acute infectious disease caused by a filtered virus, is also transmitted by mosquitoes. This disease is also called Japanese encephalitis, and it is commonly referred to as encephalitis. The patient has fever, headache, vomiting, convulsions, lethargy, coma and other phenomena.

**There is no specific drug on it, so the case fatality rate is quite high.

Mosquitoes can spread diseases, caused by the natural environment, and it is impossible to go extinct all at once.

Mosquitoes can transmit diseases, but humans also produce antibodies, so they won't go extinct.

When sucking blood, it transmits many diseases: Japanese encephalitis, malaria, dengue fever, yellow fever, ......, serious and even life-threatening.

Blood-borne diseases can all be !!

Malaria, dengue fever, Japanese encephalitis, kala-azar, yellow fever, filariasis, etc.

Japanese encephalitis is also transmitted by mosquitoes.

This is not an African primeval forest, what diseases can be transmitted, don't be too sensitive.
