According to the European Union's Copernicus Climate Change Service (C3S), July has been certified as the warmest month on Earth since records began in 1940.

Climate change has a substantial impact on the transmission and future expansion of malaria and dengue fever, two of the most important vector-borne diseases in the world. According to research by Manisha Kulkarni, an associate professor in the School of Epidemiology and Public Health at the University of Ottawa, many infectious illnesses' worldwide footprints are projected to shift as a result of climate change.

In a study by Pennsylvania State University researcher Joseph L. Servadio, it was found that mosquitoes are steadily moving northward as the globe warms. According to a recent Georgetown University study, mosquitoes have been moving uphill at a rate of 6.5 meters (approximately 21 feet) every year throughout all of sub-Saharan Africa.

John Huber and his team of researchers at Washington University are investigating the impact of seasonal temperature mean, fluctuation, and temperature at the outbreak on disease dynamics. Their research has found that warmer temperatures at the outset of epidemics encourage faster epidemics due to faster burnout of the susceptible population.

The International Centre of Insect Physiology and Ecology in Nairobi, where Jeremy Herren conducts malaria research, claims there is proof that climate change is already having an effect on where mosquito populations choose to settle. He added that it is still challenging to forecast how malaria will spread.

In the study of Joseph L. Servadio and his team, they discovered a strong parabolic relationship between maximum average monthly temperature and mosquito-borne illness outbreak risk in South and Southeast Asia using a large, structured database of reported mosquito-borne disease outbreaks from 1980 to 2009. Climate change, in conjunction with a slew of epidemiological, ecological and socioeconomic factors, will continue to have an impact on the resurgence and reemergence of vector-borne diseases.

Can humans get rid of mosquitoes completely? According to Váleri N. Vásquez, a researcher at the University of California, a promising biocontrol technology replaces wild mosquitoes with those carrying the virus-blocking Wolbachia bacterium.

Because the most often employed strain, wMel, is harmed by heat stress, they investigated how global warming would damage wMel-based replacement.

They selected two urban environments to carry out the trials. The study showed that the technique could be effective under projected heat wave scenarios up to the 2030s. However, its effectiveness under longer-term warming has potential vulnerability.

Mosquito-borne diseases, including malaria, dengue fever and Zika virus infections, affect millions of people and may pose an even greater risk under future climatic conditions as temperatures affect the geographic distribution and prevalence of these diseases.
