[Malaria in the United Nations troops in the Democratic Republic of the Congo during 2005]. / Importance du paludisme au sein des troupes Onusiennes en République Démocratique du Congo, 2005.

This prospective study examined malaria among United Nations troops participating in Operation MONUC in the town of Bunia in the Democratic Republic of Congo from April through October, 2005. Of 245 soldiers hospitalized, 105 were diagnosed with malaria, 93.6% with Plasmodium falciparum. All but one were men, and their median age was 43.5 years (range:29-52 years). South African (40/105) and Moroccan (22/105) soldiers accounted for the majority. Cases were collected mainly from May through July.

Resurgence of measles in the French military forces in 2010.

Since the start of 2010 there has been a flare-up of measles in France, following on the resurgence observed in 2008. The aim of this study was to present results of the epidemiological surveillance of measles in the French armed forces and to describe the increase in incidence. Measles was surveyed from 1992 to 2010. Criteria for report were those used for French national compulsory notification. The data, concerning active military personnel, were provided by the physicians in the armed forces using anonymous data collection forms. Between 1992 and July 2010, 689 cases of measles were notified. Since 2002, the mean incidence rate was 1 case per 100,000. A significant increase has been observed for 2010 (13.9 cases per 100,000 in 2010 versus 1.8 in 2009). The 28 cases reported in 2010 involved five clusters and three isolated cases. The mean age of affected subjects was 27 years. Only 30% of cases had been vaccinated. The epidemic resurgence of measles observed in 2010 in the French armed forces follows the same pattern as that observed nationally and at European level, and can be seen as the likely consequence of inadequate vaccination cover.

[Factors predictive of good motivation to quit smoking among Moroccan smokers attending a lung disease outpatient clinic in 2008]. / Les facteurs prédictifs de la bonne motivation de cesser de fumer chez les fumeurs marocains consultant pour une symptomatologie pulmonaire en 2008.

BACKGROUND: Motivations for cessation of smoking should be studied to determine which factors have an impact. Educational messages can then be developed to help smokers become more successful in adopting healthy behavior. The objective of our work was to determine the factors influencing the quality of motivation for smoking cessation among patients attending a lung disease clinic. METHODS: Between March and June 2008, patients attending the outpatient clinical of the Moulay Youssef Hospital Department of Pneumology in Rabat were studied. Data on the smoking status and motivation to stop smoking (Richmond's test) were collected using a standardized questionnaire. A logistic regression model was developed to analyze the quality of their motivation to quit smoking. RESULTS: The median age for smoking the first cigarette was low (<20 years); pharmacological dependence on nicotine was low (Fagerström score<8 in 71.8%). More than a third of patients (36.6%) had already intended to cease smoking. According to the Richmond test, only 46.0% were well motivated (score>or=8). At multivariate analysis, factors predictive of a good motivation to quit smoking were a previous attempt to stop smoking (OR=5.4 [2.5-11.7]), severe disease (OR=3.7 [1.6-8.2]). Beginning the tobacco addiction before the age of 18 years was predictive of poor motivation (OR=2.7 [1.4-5.3]). CONCLUSION: Our investigation provides evidence in favor of searching for different factors which might affect motivation to stop smoking among patients seeking care in a lung disease clinic. Lung specialists, who manage the large majority of these patients should be particularly active in this area.

[Communicating about risks to public health]. / Communiquer sur les risques en santé publique.

The goals of public health risk communication are to explain the risks, to inform a community without causing a crisis, to implicate the population in decision-making, and to improve dialogue between organizations and communities. Based on a document entitled "Communicating about risks to public health: pointers to good practice", the authors of this article review the main principles relevant to health risk communication and present a list of key points for effective management of this communication.

[Malaria in military personnel: the case of the Ivory Coast in 2002-2003]. / Le paludisme vu des tranchées: le cas de la Côte d'Ivoire en 2002-2003.

French troops were sent to the Ivory Coast on September 22, 2002 within the framework of Operation Unicorn in response to the political unrest. From September 22 to October 20, a total of 37 cases of malaria were reported, i.e., 35.7 cases per 1000 man-months. As of October 11, the central headquarters of the Armed Services Health Corps decided to use doxycycline as the exclusive agent for drug prophylaxis in military personnel on duty in the Ivory Coast and to enhance vector control measures. The incidence of malaria decreased to 2 cases per 1000 man-months at the sixth month. A recrudescence of malaria to 15 cases per 1000 man-months was observed with the rainy season in April. During this period one person presenting severe malaria with coma required emergency evacuation to France. In May 2003, several studies were undertaken to determine the factors that caused this recrudescence. These studies included surveys to evaluate awareness concerning malaria and monitor compliance with drug prophylaxis and tolerance of doxycycline, a case-control study to identify factors related to malarious episodes and an entomological study. Awareness of malaria was high with 75% of the 477 respondents stating that malaria could be transmitted by single mosquito bite. The case-control study showed a correlation between occurrence of malarious bouts and non-compliance with drug prophylaxis (p < 10(-5)). The odds-ratio was 3.05 (95% confidence interval, 1.52-6.14) for subjects claiming zero to one incident of non-compliance per week and 7.51 (IC95%, 3.24-17.40) for those claiming more than one incident of non-compliance per week. Tolerance of doxycyline was good since 72% of respondents reported no adverse effects. The main vector was Anopheles gambiae. The number of bites per man per night ranged from 25 to 2 and the number of infected bites ranged from 2 to 3 per week. Treatment was initiated promptly using quinine at a total dose of 25 mg/kg in 3 daily doses for 7 days by the intravenous then oral route. This experience shows that malaria remains a major concern for military forces, that standardization of preventive measures in emergency situations is needed, and that enhanced vector control, verification of compliance with drug prophylaxis and prompt treatment based on the presence of a physician in each emergency outpost is crucial. These recommendation must be applied to all French military personnel in the Ivory Coast.

[Use of satellites for public health purposes in tropical areas]. / Utilisation des satellites dans le domaine de la santé publique en milieu tropical.

The epidemiological hallmark of the new millennium has been the emergence or recrudescence of transmissible diseases with high epidemic potential. Disease tracking is becoming an increasingly global task requiring implementation of more and more sophisticated control strategies and facilities for sustainable development. A promising initiative involves the use of satellite technology to monitor and forecast the spread of disease. The Health Early Warning System (HEWS) was designed based on successful application of satellite data in food programs as well as in other areas (e.g. weather, farming and fishing). The HEWS integrates data from communications, remote-sensing and positioning satellites. The purpose of this review is to present the main studies containing satellite data on public health in tropical areas. Satellite data has allowed development of more reactive epidemiological tracking networks better suited to increasing population mobility, correlation of environmental factors (vegetation index, rainfall and ocean surface color) with human, animal and insect factors in epidemiological studies and assessment of the role of such factors in the development or reappearance of disease. Satellite technology holds great promise for more efficient management of public health problems in tropical areas.

[What are incidence and prevalence]. / Que sont l'incidence et la prevalence?

Morbidity indicators are basic tools of epidemiology. In this short technical presentation, examples from tropical medicine are used to illustrate and explain the concepts of incidence, incidence rate, cumulative incidence or attack rate, incidence density rate, prevalence, prevalence rate and the link between disease prevalence and incidence.

[Health care services in the Kingdom of Morocco]. / La santé dans le Royaume du Maroc.

Kingdom of Morocco is located in Northwestern Africa on the Atlantic Ocean and the Mediterranean Sea. Its surface area is 710,850 km2. In 2001 the estimated population of Morocco was 29,800,000 people who are not equally distributed over the territory. Population growth rate is changing with a tendency toward levels similar to those in developed countries. The health care system created in 1959 has undergone several reorganizations including the most recent reform now in progress. At the present time the health care system is organized into approximately 60 medical districts. It is subdivided into two networks, i.e., an ambulatory action network and a hospital action network. The ambulatory action network provides basic health care services. It includes 2128 basic care units. Most of these units have medical equipment designed mainly for preventive medicine. The hospital action network comprises 112 hospitals classified as zone hospitals, provincial hospitals, regional hospitals, and university hospitals. Both networks receive technical and scientific support from a network of institutes, laboratories, and specialized centers. Training for health care professionals in Morocco is provided by four medical schools and two health care institutes for paramedical care specialists. Morocco is in a period of epidemiological transition characterized by the coexistence of patients with developed and developing country diseases.
