Approximately, 40% of the world’s population, mostly those living in the world’s poorest countries, are at risk of malaria. Every year, more than 500 million people become severely ill with malaria. Most cases and deaths are in sub-Saharan Africa.

Some 2500 million people, i.e. two fifths of the world's population, are now at the risk of dengue. The World Health Organization estimates there may be 50 million cases of dengue infection worldwide every year.

Approximately two million new cases of leishmaniasis occur annually, with an estimated 12 million people presently infected worldwide.

Chagas disease (American Trypanosomiasis) affects 16 - 18 million people and some 100 million, i.e. about 25% of the population of Latin America, is at risk of acquiring chagas disease.

Insecticide-treated curtains have shown to provide efficacious vector control to reduce the transmission of the aforementioned diseases. The PermaNet® technology has now been incorporated into curtains to provide a new type of tool for fighting vector-borne diseases. PermaNet® Curtains are the first long-lasting insecticide-treated curtains and its technology has been patented in many countries.

While Long-Lasting Insecticidal Nets (LLINs) prevent humans from being attacked by vectors during the night, e.g. malaria mosquitoes, the Long-Lasting Insecticide-Treated Curtains (LLITC) will also be efficacious against day-biting vectors such as dengue mosquitoes. LLIN is a personal protective tool but LLITC will protect the whole household – therefore, LLIN combined with LLITC would mean ‘day and night’ protection from disease-causing vectors.

To create a positive health impact and sustainability, consumer acceptance and usability is of prime importance. PermaNet® Curtains have therefore been developed in various colours, patterns and sizes.
