Climate change promotes mosquito transmission virus: half of the world’s population or threatened by mosquito-borne infectious diseases

According to media reports, climate change is causing warming, mosquitoes, fleas, lice and so on to migrate to new areas, and humid conditions and high temperatures are fertile ground for the spread of many deadly microorganisms, and may cause more infectious diseases. Kristie L. Ebi, lead author of the UN IPCC’s Climate Change Report and a professor at the University of Washington and chairman of the New Integrated Climate Change Assessment Committee, said temperatures that benefit mosquitoes, lice and flies are spreading diseases are coming sooner rather than later in the past, and for some mosquitoes, High temperatures also help them reproduce.

The more mosquitoes there are, the more likely they are to spread the disease, and the biggest concerns of climate change are malaria and dengue fever. At the same time, these diseases are also due to increased temperature, the spread of the spread of the expanded.

The researchers say warm, humid conditions are a breeding ground for mosquitoes, and drought increases mosquito breeding, which can congregate in household water storage tanks. Between 2004 and 2016, the number of people in the United States infected with mosquitoes, fleas, and lice tripled.

It is reported that the number of people infected with mosquito-borne dengue fever in Pakistan this year has reached 44,000, a record high. The outbreak has been linked to rising temperatures and unusual rainfall.

According to the World Health Organization, only nine countries had outbreaks of dengue fever before 1970, but now they are common in more than 100 countries, including the United States and Europe.

One research model predicts that if the rate of warming remains the same, the Aedes aegypti and Aedes aegypti mosquitoes (both vectors of dengue fever) will continue to expand, with 49% of the world’s population exposed to its threatby by 2050. The Aedes aegypti mosquito may reach higher-dimensional areas such as Chicago in 2050, driven by human travel migration and climate change.
