Background The need to control Neglected Tropical Diseases (NTDs) and sustain progress towards elimination through mass administration of medicines requires substantial communal participation. This study, therefore, assessed the knowledge and perception of attendees’ regarding NTDs and its control activities during the Inaugural World NTD day event in Ekiti State, Nigeria. Methodology A cross-sectional study involving the administration of pretested semi-structured questionnaires to consenting attendees at the Inaugural World NTD day event was conducted on the 30th January, 2020. The questionnaire collected data on attendee’s demography, knowledge and awareness about NTDs in Nigeria. Quantitative data were analysed using descriptive statistics in SPSS. 20.0 Software and expressed as frequencies and percentages. However, qualitative data to support quantitative analysis were obtained using open-ended questionnaires and analysed thematically. Principal findings/conclusion A total of 309 attendees comprising 167 (54.0%) females, and 142 (46.0%) males participated in this study. By age groupings, majority 206 (66.7%) were within 15–25 years. 167 (54.8%) of the attendees have not heard about NTDs before, whereas 77(35.0%) have heard about NTDs through the advertisement of the event. 181(63.3%) were aware of ongoing NTD control programs in schools and communities. Also, 246 (83.4%) of them have not taken or do not know anyone that has taken drugs donated in schools or communities before. The number of attendees 41(13.3%) who incorrectly classified malaria as NTDs is higher than those who recognized onchocerciasis 36 (11.7%) and worm infections 34(11.0%) as NTDs (p>0.05). This study has shown that awareness and knowledge about NTDs control activities in Ekiti State is low, thus justifying the event as an awareness day for addressing NTDs. Public enlightment and regular promotional activities such as media engagement will raise the public appreciation and participation in NTDs control activities.

Background Described as the ‘backbone of health systems’, particularly in low- and middle-income countries, community health workers (CHWs) are a critical cadre on the frontline of any outbreak response. However, it is widely recognised that CHWs are frequently lacking in appropriate support from the health system due to inadequate physical, social and financial resources. Furthermore, despite their critical role in service delivery, the health and well-being of CHWs is seldom considered and the additional emotional and physical burdens that health systems shocks can present are frequently ignored. Thus a critical step in strengthening health systems to manage disease outbreaks or other system shocks is to ensure that CHWs are adequately supported. Within this study we document the experiences of CHWs within Nigeria during the coronavirus disease 2019 (COVID-19) outbreak to understand the impact of the pandemic on CHW well-being with a view to identifying strategies that could support CHWs during COVID-19 and subsequent health system shocks. Methods This study was based in Ogun, Kaduna and Kwara States, Nigeria. We used the creative participatory methodology of photovoice with 30 CHWs (10 in each state). Participants were asked to take photos documenting their experiences of working and living through the pandemic. Participants sent photos with captions to the research team via WhatsApp following one-on-one discussions. Photos were co-analysed among participants in focus group discussions using thematic analysis. Results Our findings reveal similar experiences of CHWs across Ogun, Kwara and Kaduna States in Nigeria, providing a unique insight into how the Nigerian health system was impacted and how this closely aligns to the performance and well-being of CHWs. CHW experiences related to three overarching themes: major stressors and challenges experienced due to COVID-19 (fear of contracting COVID-19, food insecurity, personal and gendered impacts), the impact of COVID-19 on providing routine care (stigma from community members, heavy workloads and inadequate equipment provision) and motivation and support from the community (pride in their roles and valued support from community leaders). The challenges highlighted through photovoice led to developing recommendations to address some of the challenges. This included training, adequate resource provision, routine supervision and peer support. Conclusions COVID-19 highlighted the burden health workers often face. Photovoice allowed a space for frontline health workers to come together to share common experiences, particularly the psychosocial impact of working during health system shocks and its impact on performance. This underlines the need to acknowledge mental health and prioritise the well-being of healthcare staff. Sharing stories from the perspectives of health workers provides a platform to share learning and strategies on how to best support health workers holistically, particularly during health system shocks.

Background The overall burden of neglected tropical diseases (NTDs) affecting the skin is undetermined. Skin conditions are among the top 10 causes of disability worldwide. Affected persons seek treatment at advanced stages of the disease, resulting in morbidity and disability. We developed and evaluated an integrated training intervention for early case detection, referral and management of skin NTDs in two states in Nigeria. Methods This was a mixed-methods study using participatory approaches to develop specific skin algorithms and training packages for community and primary level health workers. This supported the identification, referral and clinical diagnosis of suspected cases. We used Kirkpatrick's model to evaluate the training package. Results Participants’ knowledge improved after the 2-months intervention. Across both states, knowledge retention appeared more robust for cadres at all levels: state, local government area and primary healthcare. All (100%) participants mentioned that the training assisted them in detecting, referring and managing skin NTDs. Training was understood by participants and training materials were easy to understand. Materials were also effective in educating community members about the symptoms of NTDs and supported referral to facilities for appropriate management. Conclusions Community implementers can be trained and supervised to detect people affected by skin NTDs and support appropriate management within the existing patient care pathway.

Background The impact of single-dose mass drug administration (MDA) of ivermectin for onchocerciasis on mosquito populations was investigated in Ogun State, Nigeria. Methods Indoor and outdoor collection of mosquitoes was carried out in two intervention (IC) and two control communities (CC) at three different periods: pre-MDA (baseline), 2–3 days after MDA and 13–14 days after MDA. The density and parity rate of female Anopheles and Culex mosquitoes were determined and compared. Environmental and climatic data of study locations were obtained to perform generalized linear model analysis. Results A total of 1399 female mosquitoes were collected, including 1227 Anopheles and 172 Culex mosquitoes. There was a similar magnitude of reduction in the indoor density of Anopheles by 29% in the IC and CC 2–3 days post-MDA but the reduction in indoor parity rate was significantly higher (p = 0.021) in the IC, reducing by more than 50%. In the IC, observation of a significant reduction at 2–3 days post-MDA was consistent for both the indoor density (1.43 to 1.02) and indoor parity rate (95.35% to 44.26%) of Anopheles mosquitoes. The indoor parity rate of Anopheles remained significantly reduced (75.86%) 13–14 post-MDA. On the other hand, the indoor density of Culex increased from 0.07 to 0.10 at 2–3 days post-MDA while the indoor parity rate of Culex did not change. The outdoor density of Anopheles in the IC increased (p = 0.394) from 0.58 to 0.90 at 2–3 days post-MDA; a similar observation was consistent for the outdoor density (2.83 to 3.90) and outdoor parity rate (70.59% to 97.44%) of Culex, while the outdoor parity rate of Anopheles reduced from 85.71 to 66.67% at 2–3 days post-MDA. A generalized linear model showed that ivermectin MDA significantly caused a reduction in both the indoor density (p < 0.001) and indoor parity rate (p = 0.003) of Anopheles in the IC. Conclusion Ivermectin MDA resulted in the reduction of both the survival and density of Anopheles mosquitoes. This has strong implications for malaria transmission, which depends strongly on vector survival. Graphic abstract

There are growing concerns that communities characterized with surface water, where both humans and livestock interact for agricultural, domestic, cultural and recreational purposes, are likely to support hybridization between schistosome species infecting humans and livestock. This study therefore investigated the morphometrics of schistosome eggs recovered from human urine samples in four schistosomiasis endemic communities (Imala-Odo, Abule-Titun, Apojula and Ibaro-Oyan) along the banks of Oyan River Dam in Ogun State, Nigeria. Recovered eggs were counted, photographed, and measured with IC Measure™ for total length, maximum width and a ratio of egg shape. A total of 1984 Schistosoma eggs were analysed. Two major egg morphotypes were identified: the first represented 67.8% of the eggs, with the typical round to oval shape and mean length and width of 166 μm, 66.8 μm, respectively; the second represented 32.2% of the eggs and are more elongated, with a mean length of 198 μm, and width of 71.3 μm. Our results revealed significant variations in sizes of the schistosome eggs recovered (length: t = −35.374, degrees of freedom (df) = 1982, P = 0.000; weight: t = −10.431, df = 1982, P = 0.000), with the atypical shaped eggs appearing more elongated than expected. These eggs might represent individuals with some degree of contribution from Schistosoma bovis or possibly other Schistosoma species known to be present in Nigeria. Hence, this observation calls for further molecular studies to establish the genetic information about the miracidia from both atypical and typical eggs. It is also important to establish the presence of bona fide S. bovis infection in cattle and vector snails in the presumptive areas of hybridization.
