No place in the world is free of mosquitoes, and they have always been dangerous. According to statistics, there are more than 3,000 kinds of mosquitoes in the world. According to estimates by the World Health Organization, more than half of the world’s population is threatened by mosquito-related diseases. Mosquitoes have become one of the most dangerous insects. Not all mosquitoes cause disease, though, and not all mosquito-caused diseases are fatal. But there are still some diseases that caused or transmitted by mosquitoes that we need to pay attention to.
Mosquitoes are powerful carriers and transmitters of bacteria and viruses. What is scary about mosquitoes is that when they feed on blood, they also leave their saliva in the blood of their hosts. In this way, they can transmit virus to the host and cause disease. Some of these diseases are fatal. Hundreds of millions of people are infected by mosquitoes, in which more than 800,000 people lost their lives each year. Mosquitoes cause more deaths than any other diseases in the world.
Next, let’s look at some of the most fearful situations caused by mosquitoes.
1. Malaria
Malaria is a parasitic infection that infects humans and animals through the bite of mosquitoes. Malaria was once widespread in Asia, Africa and South America. Plasmodium, the causative agent of malaria, destroys red blood cells. Common symptoms include fever, vomiting and headache. The disease can only be effectively treated if it is detected early. When caught late or in severe cases, malaria can lead to death.
2. Zika Virus
Zika virus was first identified in Africa in the mid-20th century, but has only gained prominence in recent years. In recent years, Zika virus has been found in Central Africa, Southeast Asia and India. The virus is mainly carried and transmitted by the Aedes aegypti mosquitoes. Common symptoms include fever, headache, rash and joint pain. In severe cases, Zika can cause congenital disabilities in newborns and pregnancies. Also, in recent years, Zika virus has been suspected of a link to microcephaly in babies.
3. Dengue
Dengue fever is an acute infectious disease transmitted by the bite of infected female Aedes mosquitoes. In the past 30 years, the incidence of dengue fever worldwide has increased about 30 times. The disease is endemic mainly in tropical and subtropical areas. An estimated 400 million people worldwide become infected with the dengue virus each year. The main symptoms are fever, muscle soreness and joint pain. In severe cases, there will be vomiting of blood. In some cases, dengue can lead to death.
4. Yellow Fever
Yellow fever is endemic mainly in tropical and subtropical areas of Africa and South America. It is caused by yellow fever virus infection through mosquito bites. The main symptoms of yellow fever are fever, nausea, vomiting, loss of appetite, muscle and joint pain. If untreated, yellow fever virus can also cause death of the infected.
5. Other Diseases
In addition to the diseases mentioned above, there is the West Nile virus that causes problems in humans through mosquitoes. People infected with West Nile virus show symptoms similar to those of normal flu. But if left untreated, the virus can cause a fatal neurological disease. Then there’s chikungunya. It’s also a viral disease spread by mosquitoes. The main symptoms are fever, joint pain, rash and nausea.
In the long fight against mosquitoes, people all over the world have adopted a variety of methods and accumulated rich experiences. Some people use certain light to repel mosquitoes. Others use certain smell to drive mosquitoes away. And some people reach their goal by adjusting room temperature or improving air circulation. As a professional anti-mosquito product research and development enterprise, after years of experience accumulation, we have developed a series of more efficient and environment-friendly anti-mosquito products.
