Malaria prevention News
Insecticide-treated bed nets and walls have helped prevent bites and reduce malaria, but researchers say mosquitoes are adapting to preventive conditions, leaving adults and children vulnerable in the early evening and early morning hours – when they are not under the nets or in the house.
Mosquitoes carry diseases such as malaria, dengue fever, yellow fever, the Zika virus and encephalitis.
Ghana, Kenya and Malawi were chosen because they already run large programmes to tackle malaria, including the use of bed nets, yet still have high numbers of cases.
Scientists found that while mosquitoes have a taste for humans, they tend to avoid chickens and other birds due to their smell, thereby protecting humans from mosquito-transmitted diseases

Malaria is caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes.
Symptoms of malaria include: fever, headache, chills and vomiting.
WHO said that over the past 15 years, there has been a dramatic decline in the global burden of malaria.
According to the World Health Organisation (WHO), 78% of people who die from malaria are children under 5.
It was the first time scientists had pinpointed why the immune system fails to develop immunity during malaria infection.
