Climate change, deforestation, and urbanization are some of the major risk factors behind the increasing number of outbreaks of viruses such as dengue, Zika, and chikungunya around the world, warns a study by the World Health Organization. The study says the incidence of infections caused by these mosquito-borne illnesses, which thrive in tropical and subtropical climates, has grown dramatically in recent decades. The report says cases of dengue have increased from just over half a million globally in 2000 to 5.2 million in 2019.

“It’s a simple question with a very complex answer,” said the lead study author, Clement Vinauger, an assistant professor of biochemistry at Virginia Tech University who studies the molecular genetics of how mosquitoes choose their prey. “What really matters is how the chemicals in the soap combine with the chemicals of the individual person.”
