Malaria is a serious public well being downside and will be life-threatening. The illness, principally present in tropical nations, is transmitted to people by the feminine Anopheles mosquito. Nearly half of the world’s inhabitants is liable to the illness. In 2021, as an example, round 247 million instances of malaria have been reported and about 619,000 folks died. Four African nations accounted for simply over half of all malaria deaths worldwide: Nigeria (31.3%), the Democratic Republic of the Congo (12.6%), Tanzania (4.1%) and Niger (3.9%).
Professor Olugbenga A. Mokuolu at present oversees all malaria work in Nigeria for Management Sciences for Health, a worldwide well being advisory organisation. He’s additionally the previous technical director to the National Malaria Elimination Programme in Nigeria. Molecular parasitology Professor, Segun Isaac Oyedeji, spoke to him about Nigeria’s malaria burden.
Segun Oyedeji: Nigeria has a excessive malaria burden. How did it get right here?
Olugbenga Mokuolu: It’s a mixture of many issues.
The existence of malaria wherever is an interplay between the surroundings and the organism liable for the illness, the mosquito. When you have a look at an surroundings, you’re a wide range of pure components – akin to temperature, humidity and rainfall – and man-made components, akin to drainage programs. This is as a result of sure circumstances enable mosquitoes to thrive – particularly moisture-rich environments. Mosquitoes breed by laying their eggs in stagnant water.
Nigeria’s surroundings is a beneficial one by which mosquitoes – the malaria vector – can thrive.
In phrases of environmental administration, Nigeria leaves so much to be desired. The nation has open refuse websites, blocked drainage programs, and – as a result of folks lack piped water – they retailer water at residence in containers. These all present splendid websites for mosquitoes to breed.
In phrases of humidity, Nigeria has vegetation that favours the reproductive phases of the parasite within the mosquito. Altitude additionally performs a job. And, in most of Nigeria, the altitude permits the mosquito to fly round with out a lot issue. Only the Mambilla Plateau is taken into account comparatively malaria free in Nigeria. It has an altitude that’s above 5000 toes which makes it tough for mosquitoes to inhabit.
In addition to this, Nigeria has a big inhabitants which makes malaria transmission a lot simpler. Large populations imply extra folks are likely to dwell nearer collectively, which makes it simpler for the mosquito vector to shortly discover a contact for transmission of the malaria parasite. In addition, a big inhabitants places extra strain on sanitation providers, resulting in extra mosquito breeding websites.
That’s to not say no progress has been made. The nation’s interventions haven’t been a failure altogether. My organisation is supporting Nigeria to supply preventive chemotherapy for malaria. We have reached over 25 million youngsters beneath 5 in our intervention cycles. This is proven to have vital contribution to discount in mortality. But we aren’t but the place we’re alleged to be.
Segun Oyedeji: Children are disproportionately affected. What will be carried out?
Olugbenga Mokuolu: The Nigerian authorities and its companions have singled out youngsters as the main focus of most interventions. In addition, we’d like well being system strengthening to deal with the gaps in entry significantly at communities.
The Nigerian National Agency for Food and Drug Administration And Control lately permitted the R21 malaria vaccine to be used.
Hopefully when the R21 vaccine turns into obtainable it would cut back new instances or the affect of instances. It is unclear when the vaccine could also be rolled out in Nigeria.
A current research reveals that the R21 vaccine has some efficacy. This vaccines has proven only when administered to youngsters from 5 months to 36 months previous. It is 77% efficient in stopping an infection and reduces the incidence of extreme malaria. Reducing the frequency of extreme malaria reduces the burden of malaria mortality by extension.
The vaccines gained’t be used on their very own. They might be used as adjuncts to present instruments for preventing malaria akin to preventative remedy and the distribution of mattress nets.

Segun Oyedeji: How can Nigeria cut back its malaria burden?
Olugbenga Mokuolu: New instances of malaria can solely be curbed by environmental measures, together with the usage of insecticide nets and private safety. I do know the vaccines aren’t 100% efficient, however absolutely they may provide extra prevention.
But Nigeria must step up its sport. The present National Malaria Strategic Plan 2021 to 2025 is predicated on a nicely researched mannequin. It is not enterprise as ordinary. The plan clearly reveals that if we don’t do extra, malaria will maintain rising.
But we are literally doing so much.
Take the mattress nets. These are being distributed on an virtually common foundation to eligible states. Even COVID-19 didn’t cease the distribution. Now due to the dimensions of Nigeria’s inhabitants, mattress nets are distributed in what we name mass roll out campaigns with every state doing its personal marketing campaign. The enchancment in malaria management that now we have seen the final 5 to seven years is predicated on the depth of interventions in two thirds of our states.
But Nigeria has gone additional to virtually be a worldwide instance, in methods to implement preventive chemotherapy. We have 21 states out of 36 states the place we reached over 25 million beneath 5 youngsters in every cycle of intervention. We have 4 cycles within the 12 months and this has contributed to discount in mortality.
But we might do extra.
Malaria isn’t going to be lowered considerably except Nigeria intensifies growth. Development performs a serious function in lowering the burden.

Also, infusion of funds and never simply from the federal government. There can be public-private partnership for drug producers. The authorities ought to give them a protected market and negotiate good costs. Let the producers take over distribution utilizing their very own market rules in a way that might be reasonably priced to many individuals.
We want to have a look at new initiatives and in addition place ourselves within the vaccine sport with respect to malaria.
Segun Oyedeji: How can the worldwide group – donors and help businesses – finest help Nigeria?
Olugbenga Mokuolu: International companions are supporting the nation in some ways. Largely the help is in funding and technical areas. Going ahead, nations like Nigeria will want stronger help for consolidating present positive aspects, new instruments, well being system strengthening, scaling up entry to vaccine and native manufacturing or manufacturing of malaria intervention commodities.
