RESUMO
INTRODUCTION: The development of acute respiratory distress syndrome indicates a serious form of COVID-19. Although there have been several studies on the prognostic factors of its severe form, no such study has been conducted in Burkina Faso. METHODS: This was a retrospective cohort study conducted from March 9 to June 9, 2020 in Ouagadougou, Burkina Faso which involved 456 patients with COVID-19. RESULTS: Nearly a quarter of the patients (23.2%) had presented with acute respiratory distress and 44.3% of them died. Being over 65 years old (HR: 2.7; 95% CI: 1.5-5.1) and having hypertension (HR: 1.9; 95% CI: 1-3.5) were independently associated with the risk of mortality. However, after adjustment, only age over 65 years (HR: 2.3; 95% CI: 1.2-4.3) was a risk factor for death. The survival rate for patients over 65 was 38.5% at 7 days and 30.3% at 15 days. CONCLUSIONS: Acute respiratory distress leading to death is mainly found in older people with COVID-19. Close monitoring of these high-risk patients may reduce the risk of death.

BACKGROUND: Non-communicable diseases (NCDs) represent the leading causes of death worldwide. HIV also increases the risk of developing NCDs including diabetes mellitus and hypertension. METHODS: A cross-sectional study, based on an analysis of the cohort database of the day hospital of the Souro Sanou teaching hospital in Bobo-Dioulasso (Burkina Faso). Diabetes mellitus was defined by the undergoing of anti-diabetic treatment or two successive measurements of fasting blood sugar above 7mmol/l and high blood pressure by the undergoing of antihypertensive treatment or two successive measurements of blood pressure above 140/90mmHg. Comparison of the frequency of diabetes and hypertension in the people living with HIV/AIDS (PLWHA) population on antiretroviral therapy (ART) with that of the general population of Burkina Faso was made by indirect standardization according to age and gender. RESULTS: A total of 4259 patients including 3148 women (73.9%) were included in this study. The median age of the patients was 45 years (IQR: 38-52); the median body mass index (BMI) was 19.6kg/m2 (IQR: 15.4 - 22.7) and 48.3% of patients had a BMI≥25kg/m2. The median CD4 count was 590 cells/mm3 (IQR: 417-785). The median ART duration was 8.2 years (IQR: 4.7-11.2). The majority of patients (82.9%) were on treatment combinations consisting in 2 INTI+1 NNRTI. Prevalence of hypertension was 39.8%; it was statistically higher in men than in women (45.8% versus 37.8%). Prevalence of hypertension was 87.0% higher in the PLWHA population than among same-sex and same-age subjects in the general population. Prevalence of diabetes mellitus was 7.3%. Diabetes mellitus was more common in men than in women (10.1% versus 6.3%; P<10-3). Prevalence of diabetes mellitus was 36.0% higher in the PLWHA population than among same-sex and same-age subjects in the general population. CONCLUSION: Prevalence of diabetes mellitus and hypertension was higher among PLHWA undergoing ART than in the general population. Care for the PLHWA population should more widely include NCD treatment.

INTRODUCTION: Indications for pulmonary excision are dominated by infectious pulmonary pathologies in developing countries. We conducted this study to describe the indications and results of pulmonary resections in the thoracic surgery department of the Mali hospital. PATIENTS AND METHODS: This is a retrospective and descriptive study from January 2012 to December 2019, carried out in the thoracic surgery department of the Mali hospital. It involved 76 patients who had a pulmonary resection. The variables studied were the epidemiological data, the operating indications, the therapeutic data and the prognosis. RESULTS: The mean age of the patients was 35.5 years. The sex ratio was 1.7. The average consultation time in thoracic surgery was 11.6 months with extremes of 7 days and 96 months. A history of pulmonary tuberculosis was noted in 46.1% of patients. The main indications for pulmonary resection were infectious parenchymal destruction in 64.5%, bullous dystrophy in 14.5%, bronchopulmonary cancer in 11.8% and thoracic trauma in 4% of the cases. The procedures performed were: a lobectomy (39.5%), atypical resection (36.8%), culminectomy (7.9%) and pneumonectomy (15.8%). Morbidity was dominated by thoracic empyema (9.2%) postoperative hemorrhage (5.2%), parietal suppuration (7.8%) and bronchopleural fistula (1.3%). The average length of hospital stay was 14.3 days. Mortality was 10.5%. There was a statistically significant correlation between pneumonectomy and deaths (P=0.01). CONCLUSION: Infectious lung destruction is the main indication for pulmonary resection in Mali. The consultation period is quite long. Morbidity and mortality remains high.

BACKGROUND: While dolutegravir has been added by WHO as a preferred second-line option for the treatment of HIV infection, boosted protease inhibitor (bPI)-based regimens are still needed as alternative second-line options. Identifying optimal bPI-based second-line combinations is essential, given associated high costs and funding constraints in low- and middle-income countries. We assessed the cost-effectiveness of three alternative bPI-based second-line regimens in Burkina Faso, Cameroon and Senegal. METHODS: We used data collected over 2010-2015 in the 2LADY trial/post-trial cohort. Patients with first-line antiretroviral therapy (ART) failure were randomly assigned to tenofovir/emtricitabine + lopinavir/ritonavir (TDF/FTC LPV/r; arm A), abacavir + didanosine + lopinavir/ritonavir (arm B), or tenofovir/emtricitabine + darunavir/ritonavir (arm C). Costs (US dollars, 2016), quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios were computed for each country over 24 months of follow-up and extrapolated to 5 years using a simulated patient-level Markov model. We assessed uncertainty using cost-effectiveness acceptability curves, scenarios and prices threshold analysis. RESULTS: In each country, over 24 months, arm A was significantly less costly than arms B and C (incremental costs ranging from US$410-$US721 and US$468-US$546 for B and C vs A, respectively) and offered similar health benefits (incremental QALY: - 0.138 to 0.023 and - 0.179 to 0.028, respectively). Over 5 years, arm A remained the least costly, health benefits not being significantly different between arms. Compared with arms B and C, in each study country, Arm A had a ≥ 95% probability of being cost-effective for a large range of cost-effectiveness thresholds, irrespective of the scenario considered. CONCLUSIONS: Using TDF/FTC LPV/r as a bPI-based second-line regimen provided the best economic value in the three study countries. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00928187.
RESUMO
Dental extraction is one of the acts that cannot be undertaken or carried out without total analgesia. Unfortunately, the success of anesthesia is not always systematic. Failures are noted during the extraction of mandibular wisdom teeth and pain management therefore remains a challenge for their extraction. The anesthesia technique and nature of the adapted anesthetic solution are controversial. However, the most commonly used technique is the Lower Alveolar Nerve Block (IANB). This technique has disadvantages (trismus, risk of intra-arterial injection and hematoma) and a failure rate of up to 88%. In some survey, 90% of 93 practitioners had difficulty obtaining proper anesthesia. Other clinical studies have also shown overall failure rates of 37%-47%, and 15%-35% on healthy lower molars. Recent studies have evaluated the success rate of articaine at between 54% and 94%, while others have shown that for mandibular teeth, articaine is more effective in para-apical anesthesia than lidocaine. Sixty subjects were selected for the study. The aim was to evaluate the overall success rate of first intention 4% articaine para-apical anesthesia during extraction of third mandibular molars. The overall success rate of para-apical anesthesia was 87%.

Depression plays an important role in clinical worsening, morbidity and mortality related to HIV/AIDS. To describe the epidemiological and clinical aspects of depressive disorders in people with HIV in Mali. This prospective study took place in the department of psychiatry and infectious diseases at the Bamako University Hospital from July 2004 through October, 2005 and included all HIV-positive antiretroviral-naive patients with depression, diagnosed according to ICD-10 criteria. The study included 84 HIV-positive patients with a depressive disorder; our total population of HIV-positive patients was 316 during the study period, for a prevalence rate of 26.7 % in this population. The mean age of these depressed patients was 36.7 ± 8.5 years (range: 20-57); 63.1% were women, 47.7% had not attended or at least not completed primary school; 66.6% were married, and 92.9% lived in urban areas. Sad mood, anxiety, and refusal to eat were reported by 27.7%, 10.9%, and 9.1%, respectively, as a reason for consultation. Depression was associated with an anxiety disorder in 33 (39.3%) and a delusional disorder in 14 (16.7%). Severe depression was associated with low BMI and at a CD4 count <200 cells/mm3. Depression was found at a high frequency in our study. Its detection, operational research about it, and improved management are recommended to improve the health of people living with HIV.

Viral hepatitis B and C are universal public health problems. Burkina Faso is a high endemic area for hepatitis B. Patients with sickle cell disease are at risk. The aim of this study was to investigate and quantify the serological markers of viral hepatitis B and C among pediatric patients with sickle cell disease. This was a descriptive cross-sectional study, which took place from July to November 2014 at the Department of Pediatrics, University Hospital of Bobo- Dioulasso. The study included 44 SS and 26 SC sickle cell patients. General data (age, gender) and medical information (vaccinations, medical history including transfusion) were collected. Blood samples were taken for research and titration of serological markers of hepatitis viruses B and C with a commercial Elisa test on the ARCHITECT i1000® automat of Abbott Laboratories. The mean age of the patients was 7.98 years. Seventeen patients (13 SS and SC 4) had already been transfused at least once. The transfusion rate was significantly higher among the SS patients than among SC (29.5% and 15.3% respectively) patients. No patient with HBs Ag was been found. In two patients, the anti-HBc Ab was found alone. In 33% of cases, no markers of hepatitis B were found. Less than 20% of children fully vaccinated (N = 45) had a protective level of anti-HBs Ab (greater than 10 IU/l). The prevalence of anti-VHC Ab was 2.8%. No case of HBV-HCV co-infection was found. The prevention of infection is an important part of the management of sickle cell patients. Immunization against hepatitis B should be systematic. The results of this study assume that blood safety was good.

OBJECTIVE: describe the sociodemographic, clinical, therapeutic, biological profile and the observance of treatment in cases of immuno-virologic dissociation response (IVDR) in HIV-1 patients at te 12 months of antiretroviral treatment (ARVT). METHODS: This was a historical cohort study with a descriptive and analytical focus from January 2008 to December 2012; covering the IVDR cases at the day hospital of Bobo Dioulasso. We collected the data during medical consultations by means of the ESOPE software and from medical records of the patients. RESULTS: Of 2078 patients on ARVT, 84 or 4% presented one IVDR, among which 56 women (66.7%) and 28 men (33.3%). The average age was 45 years [range: 45-55 years]. At the initiation of ARVT, most patients were in clinical stage 3 or 4 of the WHO classification (57.1%). The body mass index (BMI) average was 20.5kg/m2 [IQR = 18.5 and 23]. The average number of +CD4 T lymphocyte was 42 cells/mm3 [IQR = 12- 63]. During follow-up, the median gain in BMI was 3.2 kg/m2 [IQR = 1.2 to 4.3 kg/m2], the median gain was 76 cells/µl [IQR = 60 - 88]. The viral plasmatic load of the HIV-1 was undetectable with a rate of TCD4+ < 100 cells /µl in 12 months. Factors associated with IVDR were the age between 35 and 45 years (p = 0.0009), the number of +CD4 T cells (+CD4T≤50) at initiation of ARVT (p = 0.00045 ) and the WHO classification clinical stage 3. CONCLUSION: This study demonstrates the problem of IVDR management in Bobo-Dioulasso and reminds of the interest of care follow-up of people living with HIV-1 by viral load and not only by the rate of CD4+ T especially in the decentralized structures of coverage of HIV, where changes of therapeutic mechanisms operate disjointedly.
OBJECTIF: décrire le profil sociodémographique, clinique, thérapeutique, biologique et l'observance du traitement des cas de réponse immuno-virologique dissociée (DIV) chez les patients VIH-1 à 12 mois de traitement antirétroviral (ARV). MÉTHODES: Il s'agissait d'une étude de cohorte historique à visée descriptive et analytique de janvier 2008 à décembre 2012, portant sur les DIV suivis à l'hôpital de jour (HDJ) de Bobo- Dioulasso. Nous avons recueilli les données au cours des consultations médicales à l'aide du logiciel ESOPE et à partir du dossier médical des patients. RÉSULTATS: Sur 2078 patients sous ARV, 84 soit 4% présentaient une dissociation immuno-virologique (DIV), dont 56 femmes (66,7%) et 28 hommes (33,3%). L'âge médian était de 45 ans [EIQ = 45 55 ans]. A l'initiation du traitement ARV, la plupart des patients étaient aux stades cliniques 3 ou 4 de l'OMS (57,1%). La médiane de l'IMC était à 20,5kg/m2 [EIQ=18,5 et 23 ans]. La médiane du nombre de lymphocyte TCD4+ était de 42 cellules/mm3 [EIQ= 12 63]. Au cours du suivi, le gain médian en indice de masse corporelle était de 3,2 kg/m2 [EIQ=1,24,3 kg/m2], le gain médian en TCD4+ était de 76 cellules/µl [EIQ=60 88]. La charge virale plasmatique du VIH-1 était indétectable chez tous avec un taux de TCD4+ < 100 cellules/µl à 12 mois. Les facteurs associés à la réponse immunovirologique dissociée étaient l'âge compris entre 35 à 45 ans (p = 0,0009), un nombre de lymphocytes T CD4 (CD4≤50) à l'initiation du traitement ARV (p=0,00045) et le stade clinique OMS 3. CONCLUSION: Cette étude prouve la problématique de la gestion de la réponse immuno-virologique dissociée à Bobo-Dioulasso, et rappel tout l'intérêt du suivi des PvVIH par la charge virale et non seulement par le taux de TCD4+ surtout dans les structures déconcentrées de prise en charge du VIH, où des changements de régime thérapeutique s'opèrent à tord.
RESUMO
A new disease was identified on the biofuel crop Jatropha curcas in 2012 in Burkina Faso that is causing serious yield losses. The disease was found to be widespread in both Sissili and Comoé Provinces. It causes characteristic leaf lesions, fruit necrosis, and cankers on young stems and branches. There was evidence of multiple infections on plants over the growing season, with regrowth evident from below old cankers, but there was little fruit production from infected branches. A detailed monitoring and assessment was undertaken of the disease progress in a severely infected field, over a 7-week period. The disease symptoms progressed from chlorosis through a necrotic phase and, in approximately 83% of replicates, stem cankers developed that resulted in dieback and lodging of branches. Colletotrichum truncatum and a member of the species complex C. gloeosporioides sensu lato were consistently isolated from fresh stem samples showing early symptoms (chlorosis). Koch's postulates were undertaken, to establish the pathogenicity of the two species. No symptoms were observed on plants inoculated with C. gloeosporioides; however, leaf and stem lesions developed after inoculation with C. truncatum, which was reisolated from the diseased tissue, confirming it as the disease-causing agent. Preliminary management practices for the disease are proposed.
RESUMO
Blood exposure accidents are the source of major risks of contamination of healthcare personnel. The objective of this study was to describe the knowledge of standard precautions, and the attitudes and practices of nursing and midwifery students in relation to this accidental exposure. This cross-sectional survey, conducted in November 2011, was based on voluntary anonymous questionnaires completed by students working in the medical ward of the Bobo-Dioulasso teaching hospital. Of the 275 students asked to participate, 219 (92.8%) completed the questionnaire: 138 (63,0%) were student nurses and 81 (37.0%) student midwives. Their mean age was 27.9 ± 5 years. Among them, 64 (29.1%) acknowledged accidental exposure to blood during treatment performed as part of their hospital work. Only 30 of these 64 cases were reported at the time. The standard precautions for the prevention of these accidents were known to 131 students (59.8%); 58.4% always wore gloves for invasive procedures; 74.9% reported that the syringe container was "always" or "often" used. The needles used were "always" or "often" recapped before disposal in only 39.1% of cases. Only 11.0% were fully vaccinated against hepatitis B. Blood exposure accidents were not uncommon among these students and their knowledge of the standard precautions and actions to take in case of an accident is insufficient. These data show the need for further training and awareness campaigns to improve these hospital practices.

Highly active antiretroviral therapy (HAART) has reduced morbidity and mortality of HIV but has led to an increasing metabolic cardiovascular risk. A cross-sectional study was conducted from May to September 2011 in Day Care Hospital for HIV-Patients of Bobo-Dioulasso. We included in this study 400 patients infected by HIVon antiretroviral therapy ≥ 6 months selected by a random draw. Metabolic syndrome was assessed according to the definitions of the IDF and ATP-III. The high risk of cardiovascular disease in 10 years was defined by a Framingham score ≥ 20%. The average age of our patients was 41.4 years [20-76]. 17% received an IP. The average duration of PI exposure was 35.5 months and 50.1 months for NNRTI. The prevalence of diabetes was 1.3% (95% CI: 0.5-3) and that of hypertension of 12.0 % (95% CI: 9.3-16). The prevalence of metabolic syndrome according to IDF was 10% (95% CI: 7.3-13.5) and the metabolic syndrome according to ATP-III 12.3% (95% CI: 9.3-16). The body mass index was higher (BMI 25.2 vs. 22.5 kg/m(2), p <10(-3) with ATPIII and BMI 26.6 vs. 22.4 kg/m(2), p <10(-3) with IDF), and duration exposure to ARVs longer in patients with metabolic syndrome regardless of the definition used (58.6 months vs 27.9 months). High cardiovascular risk was present in 1.8% (95% CI: 0.8 to 3.7) of our patients, all male more than half (n=4/7) of them were smoking. The choice of antiretroviral therapy must take into account its potential long-term toxicity. It should also strengthen supervision.

The objective of this study was to evaluate the effectiveness and the clinical tolerance of a combination containing TDF/FTC/EFV in the treatment of HIV infection. This was a retrospective and descriptive study which included 196 adults infected by HIV-1 and treated by a combination containing TDF/FTC/EFV during 29 months in the daily hospital of Bobo Dioulasso. The median duration of follow-up was 7 months IQR [5-14 month]. The median age was 37 years IQR [31-45].With the initiation of treatment ARV, the median of the index of body mass was of 19 IQR [17-22]. The median of the lymphocytes TCD4 was 201/µl IQR [74-298/µl]. During the follow-up, we reported 25 deaths (12.8%). HIV-1 RNA plasma viral load was undetectable in 91.9% of the patients (124/135) at six months of treatment. The majority of the adverse effects of the treatment were of a neurosensory nature (40.5%). The TDF/FTC/EFV combination showed a good effectiveness in the treatment of the infection with HIV-1 in the first intention just as a good clinical tolerance.

OBJECTIVE: The authors had for aim to assess the prevalence of hepatitis B co-infection in a cohort of HIV-infected patients, routinely followed-up at the Day Care Unit of the Bobo Dioulasso Sanou Souro University Hospital, Burkina Faso. PATIENTS AND METHODS: The Elisa technique was used to dose HBs antigen (AgHBs), antibodies anti-HBs and anti-HBc in all the patients followed by the biological laboratory, from October to December 2008. RESULTS: The AgHBs prevalence was 12.7% [CI at 95%: 10.7-15.0%] and men were slightly more likely to be positive for AgHBs than women (16.5% [12.0-21.9%] versus 11.6% [9.4-14.1%]; P=0.047); 83.3% of the patients [80.8-85.6%] were positive for hepatitis B core antibody, and 32.6% [29.7-35.6%] for hepatitis B surface antibody; 29.9% of the patients [27.1-32.8%] had a complete profile of former hepatitis B infection, 41.3% [38.2-44.4%] expressed core antibodies only; 13.8% [11.7-16.0%] had a negative serological test, and 2.3% [1.5-3.4%] presented a vaccinal immunity. CONCLUSION: These results stress the usefulness of screening for hepatitis B in all HIV-infected patients, along with the initial biological tests. This would help adapt HIV treatment to co-infected patients and to build an expanded program of vaccination for non-immune patients.

Dental amalgam is a metallic restorative material that is used for direct filling of carious lesions since many years. The use of this material generates solid and particulate wastes that present potential challenges to the environment. This study was carried out to assess amalgam use and waste management protocols practiced by Moroccan and Burkinabe dentists. A cross-sectional study was made of 79 in Rabat, Sale and Temara in Morocco and 56 in Ouagadougou, Bobo-Dioulasso in Burkina-Faso. The results showed that 69.5% of dental amalgam waste in Morocco vs 49.9% in Burkina-Faso was disposed with household waste which is a problem for both the environment and a risk to human being. Proper methods of dental amalgam waste disposal should be carried out to prevent indirect mercury poisoning for human.

OBJECTIVE: Vaccination against Haemophilus influenzae type b was introduced in Burkina Faso on 1st January 2006. This study thus sought to determine the impact of the first 30 months of vaccination on admissions for Hib meningitis in the department of pediatrics at the Sourô-Sanou University Hospital in Bobo Dioulasso. METHODS AND PATIENTS: Retrospective study of children aged zero to 14 years hospitalized from 1st January 2004 to 30th June 2008 for acute bacterial meningitis (laboratory-confirmed). RESULTS: During the study period, 416 children were admitted for acute bacterial meningitis. The bacterium isolated was identified in 386 cases and unidentified in 30 cases. Hib meningitis accounted for 42.3 % of the cases of identified bacterial meningitis before the introduction of the vaccine (2004 to 2005). This rate declined to 11.8 % for the first 30 months of vaccination (p < 0.001). No cases of Hib meningitis have been reported in the first half of 2008. CONCLUSION: Admissions for Hib meningitis in the Department of Pediatrics have practically disappeared two years after the introduction of the Hib vaccine into Burkina Faso's expanded program on immunization.

La meningite bacterienne aigue (MBA) est une urgence medicale par ses complications potentielles; elle justifie un diagnostic et traitement precoces. La strategie nationale au Burkina Faso recommande une reference de tous les cas suspects au Centre Hospitalier Universitaire Souro Sanou; habilete a confirmer le diagnostic par analyse du liquide cephalo-rachidien. Methodes. Les auteurs; a travers une etude transversale et analytique; ont recherche les donnees epidemiocliniques des cas suspects referes; en vue de valider l'approche syndromique; dans l'orientation dudiagnostic de la meningite. La specificite; la sensibilite; et la valeur predictive positive des donnees cliniques ont ete determinees; par rapport a la confirmation apportee par la culture du LCR; selon les recommandations de STARD et de l'OMS. Resultats. Au total; 377 patients ont ete enregistres; soit un taux de 2;4; par rapport a l'ensemble des malades admis pendant la periode d'etude. La fievre (81;6) et la raideur de nuque (72;9) ont ete les observations cliniques les plus frequentes ; le bombement de la fontanelle (31;6) et les convulsions ( 23;1); etant l'apanage des patients pediatriques. La culture du liquide cephalorachidien (LCR) a ete positive chez 207 sujets (54;9) avec tableau clinique suggestif; et chez 97 patients sans triade symptomatique classique; meme si la fievre etait presente dans tous les cas (T. 38C). La specificite et la valeur predictive positive du tableau clinique etaient de 100dans la confirmation du diagnostic par la culture. Conclusion. Cette enquete montre la pertinence de l'examen clinique dans l'approche diagnostique de la MBA au niveau des centres de sante; tout en relevant le role determinant de la culture du LCR dans la confirmation de la pathologie

The purposes of this study were: (1) to describe the genetic variability of HIV strains found in Burkina Faso, (2) to characterize non-B HIV strains mutation profiles selected by ARVs and (3) to detect possible resistances induced by ARV drugs. From 30 October 2002 to 20 November 2003, 132 HIV 1-positive patients taking Highly Active Antiretroviral Therapy (HAART) for more than one year in Bobo-Dioulasso and Ouagadougou were included. T-CD4+ lymphocytes count was done using Dynabeads technique while genotypic test and ARV-resistance tests were conducted using Pol sequencing that codes for reverse transcriptase reverse, integrase and protease. Due to undetectable viremia, 86 samples out of 132 could not be characterized. Whereas in the 46 others that had a viral load exceeding 1000 copies mL(-1), the following HIV-1 subtypes were identified: CRF06 (54,55%); CRF02(38,63%); CRF01 (4,55%) and subtype A (2,27%). In addition, several mutations related to PI, NRTI and NNRTI resistance were isolated in 27 samples. This study found a huge genetic HIV-1 polymorphism in Burkina Faso. The level of acquired resistance to ARV after one year of treatment amounted 20.4%. These results clearly show that there is imperative need to set up an ARV resistance surveillance network in Burkina Faso to guide treatment strategies and follow the extension of the phenomenon in the country.

In Burkina Faso, monitoring of acute meningitis epidemics is difficult to be implemented by routine bacteriology. The Polymerase Chain Reaction (PCR) that freed us from some constraints should allow better documentation of acute bacterial meningitis epidemics [7]. It was about a transverse study with descriptive aim along one year. The recruitment of cases was exhaustive and sample was representative of population at risk. Among the suspected ABM, 87 cases were confirmed by all biological diagnosis methods. Among these 87 confirmed cases, 82.7% were PCR positive. The culture was performed in 82 cases and 54.5% were positive. A statistical difference was observed. The sex ratio was 1.4:1, the average age of patients was 11± 4, 6 years [0-59], 26.4% of cases were observed on less than one year. Meningococcal meningitis ranked first with a rate of 46%. The peak incidence was observed during week 13-2003 or 15, 3%. The weeks pre and per epidemic (week11-week 13) PCR had the highest rate of confirmation for Neisseria meningitidis 78, 8%. The W135 was the most represented or 91%. PCR is thus an excellent alert tool for acute meningitis epidemics.
