    Dog rabies control in West and Central Africa: A review
    (Elsevier BV, 2020-05-11) Mbilo, Céline
    Rabies is a neglected but preventable zoonotic disease that predominantly affects the most vulnerable populations living in remote rural areas of resource-limited countries. To date, every country on the African mainland is considered endemic for dog-mediated rabies with an estimated 21'500 human rabies deaths occurring each year. In 2018, the United Against Rabies collaboration launched the Global Strategic Plan to end human deaths from dog-mediated rabies by 2030. The epidemiology of rabies from most Western and Central African countries remains poorly defined, making it difficult to assess the overall rabies situation and progress towards the 2030 goal. In this review, we attempt to provide an overview of the current rabies situation in 22 West and Central African countries based on published scientific literature and information obtained from rabies focal points. To this end, information was collected on i) established surveillance, ii) diagnostic capacity, iii) post-exposure prophylaxis (PEP) availability and coverage, iv) dog population estimates, v) dog vaccination campaigns, vi) animal and human health communication (One Health), vii) molecular studies, viii) Knowledge, Attitude and Practices (KAP), ix) cost estimates and x) national control strategies. Although rabies is a notifiable disease in the majority of the studied countries, national surveillance systems do not adequately capture the disease. A general lack of rabies diagnostic capacity has an additional negative impact on rabies surveillance and attempts to estimate rabies burden. Recurrent shortages of human rabies vaccine are reported by all of the countries, with vaccine availability usually limited to major urban centers but no country has yet adopted the new WHO-recommended 1-week intradermal vaccination regimen. Most countries carry out subsidized mass dog vaccination campaigns on World Rabies Day. Such activities are indispensable to keep rabies in the public consciousness but are not of the scale and intensity that is required to eliminate rabies from the dog population. Countries will need to scale up the intensity of their campaigns, if they are to progress towards the 2030 goal. But more than half of the countries do not yet have reliable figures on their dog populations. Only two countries reached stage 2 on the Stepwise Approach towards Rabies Elimination ladder - indicating that their national governments have truly prioritized rabies elimination and are thus providing the necessary support and political buy-in required to achieve success. In summary, the sub-region of West and Central Africa seems to be divided into countries which have accepted the challenge to eliminate rabies with governments committed to pushing forward rabies elimination, while other countries have achieved some progress, but elimination efforts remain stuck due to lacking government commitment and financial constraints. The possibility to meet the 2030 goal without international solidarity is low, because more than two-thirds of the countries rank in the low human development group (HDI ≤ 152). Leading countries should act as role models, sharing their experiences and capacities so that no country is left behind. Unified and with international support it is possible to reach the common goal of zero human rabies deaths by 2030.

    Factors associated with perceived barriers to canine rabies vaccination among owners of unvaccinated dogs in Sierra Leone
    (Elsevier BV, 2025-09-27) Mshelbwala, Philip P
    Dog vaccination is the most effective method for preventing rabies virus transmission and human deaths. However, in Sierra Leone, vaccination rates remain low, and the reasons for non-vaccination are not well understood. We analysed 2023 household survey data using a hierarchical Bayesian multinomial regression to provide insight into perceived barriers to canine rabies vaccination among owners of unvaccinated dogs. Our results indicated that of the 2558 dog-owning households interviewed, only 14 % (358) reported having fully vaccinated their dogs. Of the 2200 respondents with unvaccinated dogs, most (71.6 %) didn't know how to access rabies vaccination services, 17.6 % cited cost, and 10.8 % believed it was unimportant. Posterior distribution of our model showed that urban residents had 91 % lower odds of believing rabies vaccination was unimportant compared to rural residents (OR = 0.11, 95 % CrI: 0.02-0.34). Similarly, individuals with tertiary education had 28 % lower odds of believing rabies vaccination was unimportant (OR = 0.72, 95 % CrI: 0.31-1.59), though this effect is uncertain despite an 80 % probability of being protective. Respondents in areas without veterinary services were more likely to cite cost as a barrier. Students were significantly less likely than civil servants to consider rabies vaccination unimportant (OR = 0.41, 95 % CrI: 0.17-0.95). In contrast, owners of free-roaming dogs were significantly twice as likely to believe that rabies vaccination was unimportant (OR = 2.41, 95 % CrI: 1.15-5.59). Those with partially confined dogs were significantly more likely to report not knowing how to access rabies vaccination services (OR = 1.99, 95 % CrI: 1.39-2.86). Compared to households citing cost, those in the Eastern Province were significantly less likely to report that the vaccine is unimportant. Respondents in the Western Area were significantly less likely to report cost as a barrier. In contrast, households in the Eastern were more likely to report cost as a barrier. These findings suggest that barriers to dog vaccination in Sierra Leone are shaped by a combination of informational, socioeconomic, and geographic factors. Improving public awareness, especially in rural areas, and expanding access to veterinary services could help address key obstacles. Tailored outreach strategies that consider education levels, occupation types, and local infrastructure are recommended to enhance vaccination uptake and support rabies prevention efforts.
