The World Health Organization (WHO) warns that a newly discovered mosquito species, commonly referred to as “Steve” (scientifically Anopheles stephensi), is responsible for an increase in malaria cases in Africa, raising concerns about public health.
“Steve” mosquito, which originated in South Asia, was discovered for the first time in Djibouti in 2012, since which the rate of malaria in the nation has risen dramatically.
Subsequently, the mosquito has spread to seven African countries, including Ethiopia, Sudan, Somalia, Kenya, Nigeria, and Ghana.
Distinguishing itself from other mosquitoes that typically breed in rivers and swamps, the “Steve” mosquito is an urban breeder, thriving in dry environments.
It is especially difficult to control because of its low moisture tolerance and ability to thrive by using water that is trapped in gutters, tires, and containers.
Very concerning is the peculiar behaviors of this new species, which include biting outside in the daytime and showing resistance to widely used pesticides.
