The connection between climate change and a long list of diseases was found by scientists from the University of Hawaii at Manoa.
According to their study, disease-causing microbes and viruses adapt to global climate change much better than humans. The hotter they are, the better.
Climate change such as heat waves, increasing wildfires around the world, ocean acidification, soil change, droughts and floods have caused the 218 known diseases to spread faster and affect more people.
The first reason for this situation is that carriers of diseases have become closer to people. Climate warming has expanded the habitat of ticks, mosquitoes, fleas, birds and a number of rodents – carriers of dengue fever, malaria, chikungunya fever, plague, Lyme disease, West Nile virus, Zika virus, hemorrhagic fever, trypanosomiasis and echinococcosis.
The second reason is that people during climatic migrations (forced evacuation due to tsunamis, tornadoes, floods, droughts and other natural disasters, which have become many times more) get together in large groups, which contributes to the spread of infectious diseases. In addition, in a stressful situation, a person’s immunity falls, the body is more easily attacked by pathogens.
The third reason is that the period of hot weather has increased. This made the viruses more aggressive, virulent. At the same time, the extended warm season has increased the population of ticks and mosquitoes – carriers of dangerous infections. As a result, the incidence of borreliosis, West Nile fever and hemorrhagic fever has increased in the world.
Drought, floods and other natural disasters always lead to poor sanitation. This has led to an increase in the number of cases of chlamydia, cholera, conjunctivitis, cryptosporidiosis, diarrheal diseases, dysentery, giardiasis, salmonellosis, scabies and typhoid fever worldwide.
