Japanese paint to help Zambia eliminate malaria

The paint technology disrupts the mosquito’s nervous system on contact, reducing its ability to remain on walls where the paint has been applied.

The insect typically alights on vertical structures, which is why inside walls have been a key focus of anti-malarial efforts, such as the spraying of DDTs on them.

“The knock-down effect lasts for up to two years, offering lasting protection from malaria infection and other mosquito-borne diseases,” Kansai said.

The world has made huge strides against malaria since 2000, with death rates plunging by 60 percent and at least six million lives saved globally, the World Health Organisation says.

But efforts to end one of the world’s deadliest diseases – which kills about 430,000 people a year, mostly children in sub-Saharan Africa – are under threat as mosquitoes become increasingly resistant to measures such as bed nets and drugs.
