Community-based surveillance can be an important component of early warning systems. In 2016, the Côte d'Ivoire Ministry of Health launched a community-based surveillance project in 3 districts along the Guinea border. Community health workers were trained in detection and immediate reporting of diseases and events using a text-messaging platform. In December 2017, surveillance data from before and after implementation of community-based surveillance were analyzed in intervention and control districts. A total of 3,734 signals of priority diseases and 4,918 unusual health events were reported, of which 420 were investigated as suspect diseases and none were investigated as unusual health events. Of the 420 suspected cases reported, 23 (6%) were laboratory confirmed for a specific pathogen. Following implementation of community-based surveillance, 5-fold and 8-fold increases in reporting of suspected measles and yellow fever clusters, respectively, were documented. Reporting incidence rates in intervention districts for suspected measles, yellow fever, and acute flaccid paralysis were significantly higher after implementation, with a difference of 29.2, 19.0, and 2.5 cases per 100,000 person-years, respectively. All rate differences were significantly higher in intervention districts (p < 0.05); no significant increase in reporting was noted in control districts. These findings suggest that community-based surveillance strengthened detection and reporting capacity for several suspect priority diseases and events. However, the surveillance program was very sensitive, resulting in numerous false-positives. Learning from the community-based surveillance implementation experience, the ministry of health is revising signal definitions to reduce sensitivity and increase specificity, reviewing training materials, considering scaling up sustainable reporting platforms, and standardizing community health worker roles.

In Côte d’Ivoire, rabies is endemic and remains largely uncontrolled. The numbers of human exposures and rabies cases are unknown and are probably much higher than reported. Data on human rabies cases are collected by the National Institute of Public Health (NIPH) Anti-rabies Center in Abidjan through a network of 28 NIPH local units, which cover the population of the entire country. During 2014, the NIPH initiated a program to reinforce the human rabies surveillance system in those 28 NIPH local units, with specific goals of improving the infrastructure, training, communication, and government involvement. Here, we report the progress and findings during 2014–2016. The reinforced system recorded 50 cases of human rabies (15–18 cases/year; annual incidence = 0.06−0.08 per 100,000) and more than 30,000 animal exposures (annual incidence = 41.8−48.0 per 100,000). Almost one-half of the human rabies cases were in children ≤15 years old. All were fatal and dog bites were the most common route by which rabies virus was transmitted. In the 32 cases where samples of sufficient quality for analysis were available, rabies was confirmed by reverse transcription-polymerase chain reaction RT-PCR. Post-exposure prophylaxis with rabies vaccine was administered to all animal exposure victims presenting at the NIPH local units, although only about 57% completed the full immunization schedule. All available reports were provided by the NIPH local units, indicating effective communication between them and the NIPH Anti-rabies Center. These findings indicate that the reinforcements resulted in highly specific detection of human rabies, provided detailed epidemiological data about these cases, and improved estimates of animal exposure numbers. These represent substantial advances, but further improvements to the surveillance system are needed to increase disease awareness and capture cases that are currently missed by the system. In the future, better communication between local health centers and the NIPH units, surveillance at the local health center level, and increased veterinarian engagement will help provide a more complete picture of the rabies burden in Côte d’Ivoire.

Despite the availability of effective anti-rabies vaccine, rabies keeps affecting people in developing countries such as Côte d'Ivoire. The low compliance with Post Exposure Prophylaxis (PEP) partially explains this situation. This study was aiming at studying the reasons to abandon PEP. This descriptive and cross-sectional study has taken place at the anti-rabies Center of Abidjan from October 1st to December 2009. Data were collected in two steps: we first interviewed all the patients at the anti-rabies center during their first consultation, and then phone interviews were conducted one month later, only with exposed patients who abandoned their PEP. These phone calls allowed us to complete the questionnaire (the status of the animal and PEP discontinuation). Patients' verbal informed consent was obtained prior to data collection. Besides, patients were explained the risks they were exposed to and were advised to complete immunization. The results obtained revealed that, out of 220 people included in the study, 116 (52.7%) abandoned the PEP. The compliance was lower with the protocol of five injections compared to that of four injections. More than half of the patients abandoned PEP after the first injection. In 32.8% of patients who abandoned PEP, the animal was dead, disappeared, was destroyed or there were no information about it one month after bite or scratch. Animal owners' refusal of taking in charge the victims (20%) and the lack of financial resources for purchasing the vaccine (13.6%) were the most frequent reasons to abandon PEP. To increase the protection of the human population against rabies and to increase the compliance with PEP protocols, the improvement of financial accessibility to the vaccine for population and the elaboration of compulsory regulations for animal owners to take in charge the PEP are necessary.
