CNN —Genetically engineered mosquitoes have been released in the tiny East African country of Djibouti to combat a surge in malaria infections caused by an invasive vector. Unlike most malaria-transmitting mosquitoes in Africa that breed in rural areas, Anopheles Stephensi thrives in urban environments, intensifying the public health challenge for predominantly urban Djibouti. “This mosquito poses a huge threat to our fight against malaria,” said Grey Frandsen, CEO of US-owned biotechnology firm Oxitec, which developed the gene-modified mosquitoes released in Djibouti. ‘Using mosquitoes to fight mosquitoes’Dubbed a method that “uses mosquitoes to fight mosquitoes”, Oxitec’s genetic technology targets female mosquitoes, which are predominantly responsible for malaria transmission. Although the rollout of genetically modified mosquitoes in Djibouti is only the second in Africa, the idea is drawing more interest on the continent.

Climate change may be driving the rapid spread of Candida auris, a deadly fungus, across the US. Three charts show how extreme weather and environmental changes help spread disease. Nicolas Armer/picture alliance via Getty ImagesA leading theory on this fungus's sudden emergence and wide spread is that it's fueled by climate change. Whatever survives, however, is adapted to extreme heat — including the fever our bodies produce to kill off pathogens.

A new study shows extreme weather, ocean changes, and land disruption have already helped spread more than 200 pathogens. That's an extreme case of climate change creating new contact between humans and infectious diseases, but the phenomenon is widespread. Extreme heat waves, for example, can kill off many infectious viruses, bacteria, fungi, and the creatures that spread them.
