The Roll Back malaria project is a global action against malaria. Nigeria and indeed all the members of the United nations have agreed to bring down Malaria by the year 2015.
The chemicals known as pyrethroids have been approved for use on bed nets. The chemicals kill insects, including mosquitoes. Mosquitoes control experts mix pyrethroids with water and oil and apply it as a spray on bed nets. They kill flying adult mosquitoes. When they are properly used, pyrethroids have been found to pose very little risk to human health and environment. However, the efficiency of these nets is being threatened as there is a growing resistance of the malaria vector mosquitoes to pyrethroids. Experts believe that in areas and countries like Nigeria, there are a lot of spraying of insecticides and it is therefore likely that the mosquitoes are developing a resistance against these chemicals.
When that happens, it means that some of the mosquitoes can actually sit on the nets without dying. This does not mean that the net have become useless. It just means that in some areas, the effect will start dropping.
The big problem and the threat to malaria prevention is that there are no other groups of insecticides that can easily be used on nets because pyrethroids have the positive side that they are not dangerous. Even if a child sucks the net, it can sometimes give a little bit of skin irritation, but it's safe
Indeed there is a lot of cases of malaria.. hopefully this project is preferable
