COVID-19 knowledge, beliefs, prevention behaviours and misinformation in the context of an adapted seasonal malaria chemoprevention campaign in six northern Nigerian States.

BACKGROUND: Seasonal malaria chemoprevention (SMC) using sulfadoxine-pyrimethamine and amodiaquine is an efficacious intervention for protection of children against Plasmodium falciparum malaria during the rainy season. In response to the global COVID-19 pandemic, Malaria Consortium adapted its SMC delivery model to ensure safety of distributors, data collectors and beneficiaries. We conducted a SMC monitoring survey in July 2020 in the states of Bauchi, Jigawa, Kano, Katsina, Sokoto and Yobe, with questions on COVID-19 prevention behaviours and symptoms, and belief in misinformation. We investigated the associations between receipt of information on COVID-19 by different sources, including from SMC distributors, and these three outcomes using logistic generalised estimating equations. We also considered moderation of effectiveness of message delivery by SMC distributors and adherence to use of face coverings. RESULTS: We obtained a representative sample of 40,157 caregivers of eligible children aged 3-59 months, of which 36,914 (91.92%) reported knowledge of COVID-19. The weighted proportions of respondents who correctly identified COVID-19 prevention behaviours and symptoms, and who reported belief in COVID-19 misinformation, were 80.52% (95% confidence interval [95% CI] 80.02-81.00), 81.72% (95% CI 81.23-82.20) and 22.90% (95% CI 22.24-23.57). Receipt of information on COVID-19 from SMC distributors during the campaign was significantly associated with higher odds of caregiver knowledge of COVID-19 prevention behaviours (odds ratio [OR] 1.78, 95% CI 1.64-1.94, p < 0.001) and symptoms (OR 1.74, 95% CI 1.59-1.90, p < 0.001) and lower odds of belief in COVID-19 misinformation (OR 0.92, 95% CI 0.85-1.00, p = 0.038). The associations between message delivery by SMC distributors and the three outcomes were moderated by their adherence to face covering use. Receipt of information by other sources used to deliver government public health messages, including radio and health facility workers, was also associated with knowledge of COVID-19. CONCLUSIONS: Malaria Consortium's SMC programme was successfully adapted in the context of COVID-19 and was a conduit for high-quality public health messages. Standard SMC monitoring and evaluation activities can be adapted to gather evidence on emerging public health issues such as the global COVID-19 pandemic

Descriptive characterization of the cerebrospinal meningitis outbreak in Zamfara State, 2017-18

Introduction: Cerebro-spinal meningitis (CSM) is an epidemic-prone disease characterized by inflammation of the meninges. From epidemiological week 36, 2017 through epidemiological week 21, 2018, Zamfara State reported an outbreak of CSM that affected all the 14 Local Government Areas (LGAs). Therefore, we conducted a descriptive analysis of the outbreak to determine its epidemiology. Methods: We line-listed all suspected cases during the outbreak between September 4th 2017, and May 22nd 2018. We described the outbreak in time, place and person and calculated the attack rates by LGA and the age- and sex-specific case fatality rates (CFR). Results: A total of 1125 cases were reported with an overall attack rate and CFR of 25.2 cases/100,000 population and 7.6%, respectively. The age-specific CFR was highest among individuals aged 5-9 years (9.7%), while the sex-specific CFR was almost equal in males and females. The epidemiologic curve showed an increasing number of weekly reported cases with several peaks, the highest in week 12, 2018. A clustering of cases was seen in 2 contiguous LGAs, Bungudu and Gusau; while the highest attack rate was recorded in Shinkafi LGA (51 cases/100,000 population). Only 24% of suspected cases had their cerebrospinal fluid collected, and Neisseria meningitidis C accounted for 77.1% of causative agents. Conclusion: Zamfara State has experienced an outbreak of CSM. Training health workers and improving their skills on sample collection and treatment protocol will improve profiling of causative agents and outcomes. The use of Vaccines containing serogroup C will help to prevent future outbreaks

Facilitators and barriers to seasonal malaria chemoprevention (SMC) uptake in Nigeria: a qualitative approach

BACKGROUND: SMC was adopted in Nigeria in 2014 and by 2021 was being implemented in 18 states, over four months between June and October by 143000 community drug distributors (CDDs) to a target population of 23million children. Further expansion of SMC is planned, extending to 21 states with four or five monthly cycles. In view of this massive scale-up, the National Malaria Elimination Programme undertook qualitative research in five states shortly after the 2021 campaign to understand community attitudes to SMC so that these perspectives inform future planning of SMC delivery in Nigeria. METHODS: In 20 wards representing urban and rural areas with low and high SMC coverage in five states, focus group discussions were held with caregivers, and in-depth interviews conducted with community leaders and community drug distributors. Interviews were also held with local government area and State malaria focal persons and at national level with the NMEP coordinator, and representatives of partners working on SMC in Nigeria. Interviews were recorded and transcribed, those in local languages translated into English, and transcripts analysed using NVivo software. RESULTS: In total, 84 focus groups and 106 interviews were completed. Malaria was seen as a major health concern, SMC was widely accepted as a key preventive measure, and community drug distributors (CDDs) were generally trusted. Caregivers preferred SMC delivered door-to-door to the fixed-point approach, because it allowed them to continue daily tasks, and allowed time for the CDD to answer questions. Barriers to SMC uptake included perceived side-effects of SMC drugs, a lack of understanding of the purpose of SMC, mistrust and suspicions that medicines provided free may be unsafe or ineffective, and local shortages of drugs. CONCLUSIONS: Recommendations from this study were shared with all community drug distributors and others involved in SMC campaigns during cascade training in 2022, including the need to strengthen communication about the safety and effectiveness of SMC, recruiting distributors from the local community, greater involvement of state and national level pharmacovigilance coordinators, and stricter adherence to the planned medicine allocations to avoid local shortages. The findings reinforce the importance of retaining door-to-door delivery of SMC

Emergency response to a cluster of suspected foodborne botulism in Abuja, Nigeria: challenges with diagnosis and treatment in a resource-poor setting

Food-borne botulism is a rare, acute and potentiallyfatal neurologic disorder that results from ingestionof food contaminated by botulinum toxin releasedfrom the anaerobic, spore-forming, gram-positivebacterium Clostridium botulinum. We reported anunusual cluster of botulism outbreak with high casefatality affecting a family following ingestion ofhome-made fish. A suspected outbreak of botulismaffecting three patients in a family of six wasreported to the Nigeria Centre for Disease Control.A rapid response team investigated by line-listing allthe family members, interviewed extended familymembers, caregivers, clinicians, and nurses tocollect socio-demographic and clinicoepidemiological information using a semistructured questionnaires. We collected blood frompatients and food samples and locally made drinkfrom the family home for laboratory testing. Allfamily members ingested the same home-madefood within the 48hrs before onset of symptoms inthe index case. The clinical presentation of the threeaffected cases (AR=50.0%) was consistent withbotulinum poisoning. Two of the affected cases died(CFR=66.7%) within 48hrs of admission, beforeantitoxin was made available. The third case had amilder presentation and survived, afteradministration of appropriate antitoxin. Theremaining three children developed no symptoms.None of the samples cultured Clostridiumbotulinum. The blood samples were negative formouse lethality test. Our report describes thechallenges of diagnosis and management of rareemerging infectious disease outbreaks in resourceconstrained settings

Co-implementing vitamin A supplementation with seasonal malaria chemoprevention in Sokoto State, Nigeria: a feasibility and acceptability study.

BACKGROUND: Bi-annual high dose vitamin A supplements administered to children aged 6-59 months can significantly reduce child mortality, but vitamin A supplementation (VAS) coverage is low in Nigeria. The World Health Organization recommends that VAS be integrated into other public health programmes which are aimed at improving child survival. Seasonal malaria chemoprevention (SMC) provides a ready platform for VAS integration to improve health outcomes. This study explored the feasibility and acceptability of integrating VAS with SMC in one local government area in Sokoto State. METHODS: A concurrent QUAN-QUAL mixed methods study was used to assess the feasibility and acceptability of co-implementing VAS with SMC in one LGA of Sokoto state. Existing SMC implementation tools and job aids were revised and SMC and VAS were delivered using a door-to-door approach. VAS and SMC coverage were subsequently assessed using questionnaires administered to 188 and 197 households at baseline and endline respectively. The qualitative component involved key informant interviews and focus group discussions with policymakers, programme officials and technical partners to explore feasibility and acceptability. Thematic analysis was carried out on the qualitative data. RESULTS: At endline, the proportion of children who received at least one dose of VAS in the last six months increased significantly from 2 to 59% (p < 0.001). There were no adverse effects on the coverage of SMC delivery with 70% eligible children reached at baseline, increasing to 76% (p = 0.412) at endline. There was no significant change (p = 0.264) in the quality of SMC, measured by proportion of children receiving their first dose as directly observed treatment (DOT), at baseline (54%) compared to endline (68%). The qualitative findings are presented as two overarching themes relating to feasibility and acceptability of the integrated VAS-SMC strategy, and within each, a series of sub-themes describe study participants' views of important considerations in implementing the strategy. CONCLUSION: This study showed that it is feasible and acceptable to integrate VAS with SMC delivery in areas of high seasonal malaria transmission such as northern Nigeria, where SMC campaigns are implemented. SMC-VAS integrated campaigns can significantly increase vitamin A coverage but more research is required to demonstrate the feasibility of this integration in different settings and on a larger scale

The use of video job-aids to improve the quality of seasonal malaria chemoprevention delivery

Mobile phones are increasingly used in community health programmes, but the use of video job-aids that can be displayed on smart phones has not been widely exploited. We investigated the use of video job-aids to support the delivery of seasonal malaria chemoprevention (SMC) in countries in West and Central Africa. The study was prompted by the need for training tools that could be used in a socially distanced manner during the COVID-19 pandemic. Animated videos were developed in English, French, Portuguese, Fula and Hausa, illustrating key steps for administering SMC safely, including wearing masks, washing hands, and social distancing. Through a consultative process with the national malaria programmes of countries using SMC, successive versions of the script and videos were reviewed to ensure accurate and relevant content. Online workshops were held with programme managers to plan how to use the videos in SMC staff training and supervision, and the use of the videos was evaluated in Guinea through focus groups and in-depth interviews with drug distributors and other staff involved in SMC delivery and through direct observations of SMC administration. Programme managers found the videos useful as they reinforce messages, can be viewed at any time and repeatedly, and when used during training sessions, provide a focus of discussion and support for trainers and help retain messages. Managers requested that local specificities of SMC delivery in their setting be included in tailored versions of the video for their country, and videos were required to be narrated in a variety of local languages. In Guinea, SMC drug distributors found the video covered the all the essential steps and found the video easy to understand. However, not all key messages were followed as some of the safety measures, social distancing and wearing masks, were perceived by some as creating mistrust amongst communities. Video job-aids can potentially provide an efficient means of reaching large numbers of drug distributors with guidance for safe and effective distribution of SMC. Not all distributors use android phones, but SMC programmes are increasingly providing drug distributors with android devices to track delivery, and personal ownership of smartphones in sub-Saharan Africa is growing. The use of video job-aids for community health workers to improve the quality delivery of SMC, or of other primary health care interventions, should be more widely evaluated
