The World Health Organisation (WHO) in its report titled
“Global Technical Strategy for Malaria, 2016-2030” to mark this year’s World
Malaria Day in Geneva listed Nigeria among countries that are not ready to
eliminate malaria. This assessment seems credible because the government
agencies and NGOs that are saddled with the responsibility of combating this
dreaded disease are doing so with levity and defective strategies.
The mosquito net distribution scheme and drug therapy as
preventive and curative measures are flawed for obvious reasons. The mosquito
net can only offer limited protection within the sleeping area and not in other
locations in the house or in public places and as such unreliable as preventive
and protective measures.
The drug therapy on the other hand, offers a cure for one
infection only. Subsequent attacks which may be as many as 5-8 incidents in a
year must also be treated. The drugs are expensive and one untreated attack
could lead to cerebral malaria and death. In view of these obvious flaws, a
more practical and effective strategy must be found to fight malaria in
Nigeria. The success story of countries that focused on the elimination of
mosquito colonies based on the common sense logic of “no mosquito, no malaria”
should be explored.
The Maghreb countries in North Africa and countries in the
Caribbean Islands have achieved remarkable successes in fighting malaria by
eradicating mosquitoes by these three means viz: fumigation, larvicide and
sterilisation.
The first strategy is not new in Nigeria. In
the early years of Nigeria’s independence, sanitary teams carried out routine
fumigations in towns and villages to control and eradicate mosquitoes in their
habitats. These operations achieved a high degree of success and incidents of
malaria attacks were dramatically reduced.
The second method is
through the introduction of a non-toxic larvicide, the Bacillus Thurengensis
Israeliensis (BTI) into mosquito breeding grounds, such as gutters, sewage pits
and stagnant pools. The BTI consumes the mosquito larvae, thus preventing it from
developing further into the flying mosquito. Inevitably, the colony goes into
extinction.
The third method
involves the introduction of clinically sterilised male mosquitoes into the
wild. When the sterile male mates, the unfertilised eggs are unable to develop
into the larvae stage and so on, leading to the gradual depletion of the colony
and eventual extinction.
