Organisation et le fonctionnement de la surveillance épidémiologique de la rougeole dans le district sanitaire de Yopougon-est, Côte d'Ivoire de janvier 2022 à juin 2022 / NA

La rougeole est une maladie infantile banale, peut être mortelles quand elle est sous-estimée. Nous avons initié cette étude dont l'objectif général est d'analyser le système de surveillance épidémiologique de la rougeole dans le district sanitaire de Yopougon-Est.MéthodesNous avons procédé à une évaluation normative de la surveillance épidémiologique de la rougeole réalisée en 6 (Six) mois dans ledit district sanitaire. Les critères de sélection nous ont permis de sélectionner 30 personnels de santé impliqués dans la surveillance de la rougeole. RésultatsLes médecins étaient les plus représentés (40%), suivi des infirmiers (33,3%). Les agents avaient plus de 3 ans de service (73,3%). Plus de la moitié des agents étaient formés (56%) la moyenne d'année de service était de 5,33 ans.Dans notre étude, 93,3 % des agents connaissaient la définition d'un cas de rougeole. Les seuils d'alerte et épidémique étaient connus par 56,6% des agents enquêtés. La disponibilité des registres de consultation, fiche de notification hebdomadaire de cas au niveau des structures de santé étaient de 86,7 %. Pour la transmission des données, 70% des enquêtés avaient déclarés que les rapports se transmettaient au district hebdomadairement.Les prélèvements de sang avaient été réalisés chez tous les cas suspects (100%). Les cas confirmés de rougeole représentaient 26,8 % des échantillons.ConclusionLa rougeole est une maladie de l'enfance qui est évitable par la vaccination. Cependant à défaut de vaccination, il est impérieux de mettre en place une organisation pour la détection des cas de rougeole afin d'éviter des épidémies

Surveillance des paralysies flasques aiguës en Côte d'Ivoire de 2007 à 2016 : importance et profil épidémiologique des entérovirus non poliovirus.

INTRODUCTION: Côte d'Ivoire's status as a polio-free country requires high quality surveillance of acute flaccid paralysis. Our study aims to determine the prevalence of non-poliovirus enteroviruses found in the surveillance of Acute Flaccid Paralysis (AFP) in Côte d'Ivoire and to study their distribution according to individual characteristics and associated factors. METHOD: We conducted an exhaustive descriptive and analytical cross-sectional retrospective study on 3597 cases of acute flaccid paralysis notified in the context of surveillance of AFP from 2007 to 2016 in Côte d'Ivoire. RESULTS: The mean annual rate of non-poliovirus enterovirus over the period was 11.3% over the study period with extremes of 9.2% and 15.9%. The absence of fever at the onset of illness and early age were factors associated with the occurrence of acute flaccid paralysis due to non-poliovirus enterovirus. CONCLUSION: Our study found a downward trend in non-poliovirus enteroviruses detected in AFP surveillance in Côte d'Ivoire, and identified the absence of fever and the age of the subject as being the factors associated with their occurrence. It is therefore necessary to type all cases of non-poliovirus enteroviruses detected in AFP surveillance to assess the risks of vaccine-derived polioviruses.

[Evaluation of epidemiological monitoring of post-vaccination adverse reactions in Abidjan]. / Évaluation de la surveillance épidémiologique des manifestations adverses post-immunisations à Abidjan.

INTRODUCTION: This study was designed to evaluate the adverse events following immunization (AEFI) monitoring system in Abidjan health districts. METHODS: This cross-sectional study focused on activities conducted between 1st January and 31st December 2015 in the nine health districts of Abidjan. Data were collected by means of a questionnaire based on the model of World Health Organization evaluation forms. These questionnaires were administered to personnel in charge of epidemiological surveillance in the health districts and the personnel of district hospitals and health centres. RESULTS: The AEFI monitoring system, apart from its simplicity and flexibility, remains fairly ineffective due to the relatively low acceptability by all health workers involved. Only 4% of healthcare personnel respondents participate in this activity; 55% of health districts reported cases of AEFI and 25% of health centres reported cases of adverse events. The low acceptability makes this system less sensitive and ineffective for health policy decision-making designed to reduce adverse events following immunization. CONCLUSION: Improved performance of the AEFI monitoring system requires better training of health workers, better data processing equipment and improved community participation.

[Preparation of healthcare workers against the threat of Ebola virus disease in Ivory Coast]. / Préparation du personnel de santé d’une région sanitaire de Côte d’Ivoire face à la menace du virus Ebola.

INTRODUCTION: Since the declaration of the Ebola virus disease outbreak in West Africa, the government of Ivory Coast has organized the training of medical staff in all health regions of the country. This study was conducted one month after this training in order to assess the knowledge, attitudes and practices of health workers concerning Ebola virus disease in an Ivory Coast health region their preparation in relation to this disease. METHODS: In May-June 2014, we conducted a descriptive cross-sectional study of 176 health workers from private and public health facilities in 5 health districts. RESULTS: Among the respondents, 15.5% attended the training on Ebola disease organized by the Ministry of Health. They knew that the disease is transmitted from animals to humans by body fluids (85.6%), and from human to human by body fluids of a sick person or a cadavre (82.8%). 96% said they were at risk of contracting the disease. DISCUSSION: In view of the persistent threat of the disease, ignorance of certain aspects of the disease could be a weakness in the prevention of nosocomial transmission of the disease. Knowledge of the disease should lead to adoption of prevention measures. However, routine use of protection equipment, including gloves, depends on its availability. CONCLUSION: The lack of infection prevention and control equipment could be a weak point in preparation of the response to an Ebola disease outbreak.

[Knowledge, attitudes and practices of household heads regarding rabies in the Abobo district (Abidjan, Côte d'Ivoire) in 2008]. / Connaissances, attitudes et pratiques des chefs de ménage de la commune d'Abobo (Abidjan, Côte d'Ivoire) en matière de rage, en 2008.

INTRODUCTION: In order to investigate the factors predisposing to human rabies in Abobo, we conducted a study to assess the knowledge, attitudes and practices of household heads in this district. MATERIALS AND METHODS: This cross-sectional study was conducted from 13 September to 13 December 2008 and consisted of interviewing, by means of a questionnaire, household heads or their representatives at home. We randomly selected 53 households in each sub-district, with a total of 702 households for the 13 sub-districts. Informed consent was obtained from each participant prior to the interview. Data were analysed using Epi-Info 2000. RESULTS: Of the total of 152 households, 22% had a pet; 109 (71.7%) households had a dog, that was not vaccinated in 38% of cases. Furthermore, 577 (82.19%) of household heads knew about rabies and school was the source of information for 511 households (88.6%). Five hundred fifty five household heads (96.18%) did not know that the wound should be washed with soap and water immediately after exposure and 118 household heads (20.45%) reported that nothing should be done after a bite. After exposure, only 30.70% of household heads would attend a health centre 50 kilometres from home. CONCLUSION: This study shows a good level of knowledge of household heads concerning rabies. However, harmful health practices persist. Public awareness of rabies therefore needs to be reinforced.

[Management of the yellow fever epidemic in 2010 in Séguéla (Côte d'Ivoire): value of multidisciplinary investigation]. / Gestion de l'épidémie de fièvre jaune en 2010 à Séguéla (Côte d'Ivoire): intérêt d'une investigation pluridisciplinaire.

INTRODUCTION: In August 2010, five positive cases of yellow fever were reported in the region of Séguéla, in the northwest of Côte d'Ivoire, affected by an armed conflict since 2002. In order to evaluate the extent of yellow fever virus circulation and the risk for local people, a multidisciplinary investigation was carried out by the Côte-d'Ivoire Ministry of Health and Public Hygiene. METHODS: Theses investigations were conducted in the villages of confirmed cases and the outpatient and hospitalization centers attended by infected patients, two weeks after the reactive immunization campaign performed in order to stop the spread of the epidemic. The search for suspects identified 16 cases, including 4 cases and 2 deaths in hospital registers and 12 cases during community interviews, including 6 deaths. RESULTS: Stegomyiens indices were relatively low. Aedes aegypti was present among adult mosquitoes. In addition, three wild vectors, varying in number from one locality to another, were detected: Ae. africanus, Ae. luteocephalus and Ae. vittatus with average biting rates of 0.3; 0.1 and 0.05 bite/man/twilight, respectively, at Soba, Ae. africanus and Ae. vittatus with average biting rates of 0.25 and 0.3 bite/man/twilight, respectively, at Yaokro and Ae. luteocephalus with one bite/man/twilight at Kaborékro. DISCUSSION: Unfortunately, the vaccine response conducted before investigations did not stop progression of the epidemic which broke out three months later in the Worofla health area, close to the Magrékros encampment.

[The use of ultrasound to reduce maternal and neonatal mortality in a primary care facility in Ivory Coast]. / Apport de I'échographie dans la surveillance de la grossesse dans un établissement sanitaire de premier contact à Yopougon en Côte d'lvoire.

INTRODUCTION: In pregnancy care, ultrasound is used to detect pregnancy-related complications. The purpose of this study was to assess the use of ultrasound in monitoring pregnant women in a primary care facility for the purposes of reducing maternal and neonatal mortality. PATIENTS AND METHOD: A cross-sectional descriptive study was conducted from February 16, 2009 to April 16, 2009. Interviews were conducted with pregnancy women who had an ultrasound was recommended by a health worker or requested by the women. A Comprehensive recruitment strategy was used. The variables studied were sociodemographic characteristics, the indications or reasons for the ultrasound scan, the results of the ultrasound examination, the final diagnosis and the recommended behaviors. RESULTS: A total of 353 pregnant women aged between 15 and 45 years underwent an ultrasound examination. Sixty-six percent (66.3%) of the prescribers were midwives. In terms of pregmancy related pathologies, the main reasons for the ultrasound were pelvic pains (5.4%0, bleeding in the first trimester (4%0, and dystocia (3.7%). The main results were dystocic presentations (4.2%0, pregnancy loss (4%), and causes of bleeding in the first trimester (2.5%). As a result of these findings, 9.3% of at-risk women were sent to a specialized hospital. CONCLUSION: Ultrasound contributes to reducing maternal and dneonatal mortallity in primary care facilities. The results suggest that the health authorities need to improve equipment in primary care facilities to include ultrasound as a diagnosis tool in order to reduce maternal and neonatal mortality.

Species composition and population dynamics of Aedes mosquitoes, potential vectors of arboviruses, at the container terminal of the autonomous port of Abidjan, Côte d'Ivoire.

An entomological survey of Aedes mosquitoes was initiated at the container terminal of the Autonomous Port of Abidjan in 2009 following the occurrence of two outbreaks of yellow fever in less than 10 years and dengue cases reported in 2008 among expatriates returning from Côte d'Ivoire (Ivory Coast). It was based on regular monitoring of ovitraps from July 2009 to June 2010. A total of 4,739 adult mosquitoes represented by four species of Aedes (97% of total) and one unexpected species of Culex (3%) were obtained. Aedes aegypti was dominant with 98% of total Aedes (n = 4,594). Its density variation was closely related to the amount of rainfall. The other species of Aedes were collected in the second half of the major rainy season including Ae. albopictus (1.17% of Aedes) and Ae. angustus (0.13%) whose presence was discovered for the first time in Côte d'Ivoire.

[Seroprevalence of HIV infection in the context of a mobile counseling and voluntary testing strategy in rural areas of Côte d'Ivoire]. / Séroprévalence de l'infection à VIH en conseil et dépistage volontaire par stratégie mobile en Zone rurale en Côte d'Ivoire.

INTRODUCTION: In Côte d'Ivoire, HIV testing and counselling has been identified as a priority in the National 2006-2010 AIDS Strategic Plan, which is designed to evaluate the prevalence of HIV in rural areas measured by means of a mobile strategy. METHODS: We conducted a cross-sectional descriptive and analytical study from 1st April, 2007 to 31st March 2008 in six rural areas of Côte d'Ivoire: Dabou, San Pedro, Abengourou, Tanda, Daloa, and Soubré*. The study population consisted of subjects attending the mobile voluntary counselling and testing units. RESULTS: The mean prevalence of HIV infection in this study was 5.30%. The mean prevalence rate in men was 5.26%, with a peak of 7.55% in the 30-34 years age-group. The mean prevalence rate in women was 5.35%, with a peak of 6.59% in the same age-group. Type HIV-1 was predominant (84.2% of the total). The most affected area was Dabou, with a rate three times higher (15.83%) than the average rate observed during the study. More educated people (university level) presented 3.5-fold (for men) or 6-fold (for women) higher infection rates than illiterate people. Although 100% of people who tested positive received a medical or community referral according to their specific needs, only 62.1% were first-line referred for medical care. CONCLUSION: In the light of the results of this study, we believe that community mobilization must be redirected to the most severely affected populations to facilitate earlier diagnosis. Actions such as training and prevention based on communication to encourage changes of behaviour should therefore be priorities in the national counselling and testing programme.
