Chronicle of an outbreak foretold: meningococcal meningitis W135 in Burkina Faso.

Burkina Faso lies within the African meningitis belt. Until recently, serogroup A of Neisseria meningitidis was the most common cause of epidemic meningitis in Burkina Faso. However, during the epidemic that started in January 2002, W135 was the predominant serogroup of meningococcus. Vaccine against the W135 serogroup is expensive and in short supply. Strategies to react to a future African epidemic of W135 meningococcal meningitis with a sufficient and affordable supply of vaccine must be put into place now.

Antiretroviral use in Ouagadougou, Burkina Faso.

Burkina Faso has the second highest seroprevalence rate for HIV in West Africa, estimated at 6.5% of the population. Although it is one of the poorest countries in the world, antiretrovirals have been used on an extremely limited basis in Burkina Faso since at least the early 1990s. In this article we will review the evolution of antiretroviral availability in this country, describe the mechanisms by which drugs are being accessed, and review our experience with expanding antiretroviral access through drug donations in community-based settings. Finally, we will discuss some of the implications for future attempts to expand access to treatment for people living with HIV in Africa.

Measles incidence before and after mass vaccination campaigns in Burkina Faso.

Burkina Faso conducted mass measles vaccination campaigns among children aged 9 months to 4 years during December 1998 and December 1999. The 1998 campaign was limited to six cities and towns, while the 1999 campaign was nationwide. The last year of explosive measles activity in Burkina Faso was 1996. Measles surveillance data suggest that the 1998 urban campaigns did not significantly impact measles incidence. After the 1999 national campaign, the total case count decreased during 2000 and 2001. However, 68% of measles cases occurred among children aged 5 years or older who were not included in the mass vaccination strategy. During 2000 and 2001, areas with high measles incidence were characterized by low population density and presence of mobile and poor populations. Measles control strategies in Sahelian Africa must balance incomplete impact on virus circulation with cost of more aggressive strategies that include older age groups.

Antibiotic resistance in Burkina Faso.

Burkina Faso is one of the Subsaharan African nations. No national services for monitoring of antibiotic resistance are available, so the number of reports of resistance patterns among hospital pathogens are inconsistent. In order to evaluate antibiotic resistance, a total of 1998 valuable microrganisms were analysed during 2000 at the Medical Centre St. Camille of Ouagadougou, Burkina Faso's capital. They were isolated as follows: 1012 from urine-culture, 503 from tonsil swabs, 398 from pus, 53 from sputum and 32 from blood-cultures. Escherichia coli was the most isolated microrganism from urine (44%); Enterococcus faecalis from tonsil swabs (96.4%), Staphylococcus aureus from pus (17%) and K. pneumoniae (70%) from sputum. In general, resistance to the old antibiotics, such as aminopenicillins and cotrimoxazole was shown. The most active antibiotic was norfloxacin, a rarely used antibiotic in this country. In conclusion, our study shows that it is necessary to create antibiotic-resistance surveillance centers in the developing countries to adopt an accurate therapy to avoid exporting of antibiotic resistance to the developed countries linked to increased emigration.

[Schistosomiasis endemic in Burkina Faso].

Burkina Faso, through the works of many teams of the OCCGE based in Bobo-Dioulasso, has signi-ficant data on several tropical endemics of which schistosomiasis. With the complementary works, it appears to be possible to establish a distribution of the schistosomiasis which reveals its importance. It will be the first stage of the planned national control program. The parasitologic data-gathering which covers the period of 1951 to 2000, used all the standard techniques. It is about Kato-Kartz and MIF for the intestinal schistosomiasis, centrifugation, filtration, serology reagent strips, macroscopy of urines and echography of the urinary system for the urinary schistosomiasis. All the eleven medical areas of the country have many sites submitted to parasitologic investigation. As regard the distribution of the two parasites involved with man (Schistosoma haematobium and S. mansoni), the data of prevalence (1% to 100%) and their distribution confirm their endemicity and the focal transmission. S. mansoni is located in eight medical areas particularly in the South and the West. S. haematobium is present in all the eleven medical areas of the country. In hydraulic planning as Sourou where the prevalences went from 23% to 70% for S. haematobium and from 0% to 69% for S. mansoni between 1987 and 1998. The situation requires a continuous monitoring. The spatial distribution of the six species of intermediate hosts shows that Bulinus truncatus and B. senegalensis Soudano-Sahelian species are present in all the ecological zones. B. globosus and Biomphalaria pfeifferi meet preferentially in the southern half of the country which reinforces the observation according to which the 14th northern parallel is often considered as the limit of septentrional extension of these two species. The other species Bulinus forskalii and B umbilicatus could have preference areas. All the species show a certain affinity with a type of biotope. The rarity and temporary aquatic systems lead to a concentration of the domestic and especially entertaining children activities around these biotopes very often contaminated. The phenomenon is amplified by the increase of contacts man-water, whose frequency and intensity are themselves dependent on activities related to hydro-agricultural planning. The analysis of the data shows, that in terms of colonization of the biotopes by molluscs and the relations between parasites and intermediate and final hosts, hydraulic planning turns out to be an amplifying factor of the species proliferation and parasitic flux host-parasite.

[Assessment of an interventional study on iodine deficiency in Burkina Faso, 1990-1993. Direction de la Santé de la Famille (Burkina Faso)].

OBJECTIVES: To find how the urinary parameters of iodine excretion evolved in a community with deficiencies, after administering iodine orally and IM in two provinces in Burkina Faso; to recommend a national strategy to tackle iodine deficits. Design. A longitudinal survey before and after the iodine was given (12 months). Descriptive analysis of the data. SETTING: Provinces of Namentenga and Passoré in Burkina Faso. PARTICIPANTS: The general population of the two provinces who satisfied age-sex criteria: males from 0 to 25, females from 0-45. Randomised two-stage sampling. 423 people in all took part (210 in Namentenga and 213 in Passoré). INTERVENTIONS: The administration of 1 ml of iodised oil (Lipiodol) orally in Namentenga and IM in Passoré. MEASUREMENTS AND MAIN RESULTS: The urinary parameters of micrograms of iodine per gr. of Creatinine, and micrograms of iodine per dl of urine, were used. Figures for normalisation of the urinary parameters 12 months after iodisation was significantly higher in Passoré province, where iodine was administered IM. CONCLUSIONS: The intramuscular pathway has more longlasting effects, but the characteristics of Burkina Faso's health system and the feasibility of a medium or long-term intervention make it advisable that iodine supplements be administered orally.

Learning from health system reforms: lessons from Burkina Faso.

OBJECTIVES: Burkina Faso has implemented a macroeconomic adjustment programme (MAP) along with an ambitious reform of the health care system. Our aim was (1) to verify whether MAPs led to a reduction in health resources, and (2) to analyze the consequences of health policies implemented. METHOD: Cross-sectional and retrospective study, spanning the years 1983-2003. The macro aspect is based upon documents from national and international sources, a database of secondary socioeconomic data, and interviews of key informants working in upper management. Household and health facility surveys were conducted in three regions covering 53 communities. RESULTS: Within the reforms, the health sector benefited from an important flow of resources. There were significant increases in public expenditures, health care staff, the number of primary care facilities and the availability of generic drugs. However, health facilities in the public sector remain underused and major inequities subsist. Access to health care is constrained by the population's ability to pay. Health expenditures impoverish households, creating new poor and impoverishing the already poor. CONCLUSIONS: The success of reforms depends largely on the extent to which they remove financial barriers to access to services. The experience of Burkina Faso also reveals the need for fundamental changes that will motivate staff, improve productivity, and ensure good quality services. Integrating health development policies with strategic plans for poverty reduction can provide new opportunities for African countries to redesign their health systems within this type of perspective.

The use of impregnated curtains does not affect antibody responses against Plasmodium falciparum and complexity of infecting parasite populations in children from Burkina Faso.

In Burkina Faso, where malaria is hyper-endemic and transmission intensity is very high, the majority of malaria-related morbidity and mortality occurs in children less than 5 years of age. A control measure such as the use of insecticide-treated curtains (ITC) significantly reduces transmission of malaria infection. Concerns remain whether reduced transmission intensity may lead to a delay in the development of immunity in younger children and even to a partial loss of already acquired immunity. In this study, the levels of P. falciparum-specific IgG subclasses, the number of infecting parasite clones determined by PCR-based genotyping of the msp2 gene and the parasite density were analysed in 154 asymptomatic children (3-6 years) living in 16 villages (8 with and 8 without ITC) in the vicinity of Ouagadougou, the capital of Burkina Faso. In addition, the parasite inhibitory effects of Ig fractions, prepared from selected children, in co-operation with normal human monocytes were studied. Blood samples from asymptomatic ITC-users showed a significant decrease in P. falciparum prevalence as well as in parasite density. However, no significant difference was observed in P. falciparum-specific antibodies or in parasite multiplicity of infection between the two groups. Furthermore, Ig fractions from children of both groups showed similar levels of inhibitory activity against autologous parasite growth both on their own and in co-operation with monocytes.

Chloroquine and sulfadoxine/pyrimethamine sensitivity in Burkina Faso. In vivo sensitivity of Plasmodium falciparum to chloroquine and sulfadoxine/pyrimethamine in Burkina Faso.

Plasmodium falciparum susceptibility to chloroquine and sulfadoxine/pyrimethamine was investigated in children living in an urban district of Ouagadougou, Burkina Faso, in August 1992. A modified WHO Standard Field in vivo test was used, with follow-up on days 2, 4, 7, and 14 after treatment with 25 mg chloroquine per kg body weight given over 3 days, or with standard doses of sulfadoxine/pyrimethamine in children from 2 to 8 years old with P. falciparum monospecific infection, asexual parasitaemia > 800/microliters of blood and negative Bergqvist and Lignin urine tests. Out of a total of 515 children screened, 152 were selected and randomized into treatment with chloroquine (86 children) or sulfadoxine/pyrimethamine (66 children). With the chloroquine regimen, parasitaemia did not clear by day 7 in 7 cases (8.1%), and there was recurrence of parasitaemia in 21 subjects (24.4%) on day 14, while all the children who had received sulfadoxine/pyrimethamine were fully sensitive on day 7 and day 14. It can be concluded that sulfadoxine/pyrimethamine is a good alternative for the treatment of falciparum malaria in areas of Burkina Faso with established chloroquine resistance.

Ethnobotanical survey and in vitro antiplasmodial activity of plants used in traditional medicine in Burkina Faso.

In Burkina Faso, most people in particular, in rural areas, use traditional medicine and medicinal plants to treat usual diseases. In the course of new antimalarial compounds, an ethnobotanical survey has been conducted in different regions. Seven plants, often cited by traditional practitioners and not chemically investigated, have been selected for an antiplasmodial screening: Pavetta crassipes (K. Schum), Acanthospermum hispidum (DC), Terminalia macroptera (Guill. et Perr), Cassia siamea (Lam), Ficus sycomorus (L), Fadogia agrestis (Schweinf. Ex Hiern) and Crossopteryx febrifuga (AFZ. Ex G. Don) Benth. Basic, chloroform, methanol, water-methanol and aqueous crude extracts have been prepared and tested on Plasmodium falciparum chloroquine-resistant W2 strain. A significant activity has been observed with alkaloid extract of P. crassipes (IC(50)<4 microg/ml), of A. hispidum, C. febrifuga, and F. agrestis (4<IC(50)<10 microg/ml). The best result is obtained with aqueous extract of T. macroptera with an IC(50)=1 microg/ml. These results confirm the traditional use of these plants.

A phyto-sociological analysis of the distribution of riverine tsetse flies in Burkina Faso.

In Burkina Faso, Glossina palpalis gambiensis Vanderplank and G. tachinoides Westwood (Diptera: Glossinidae) are the main cyclic vectors of trypanosomiasis. The vegetation type along river banks is an important factor determining the distribution and abundance of these tsetse. The following work investigated the relation between the plant species present (including the disturbance level) and tsetse distribution and abundance, using three ecotypes, described by P.C. Morel in 1978. These were the Guinean, Sudano-Guinean and Sudanese gallery forests. In the Mouhoun River basin, these three ecotypes are found successively from upstream to downstream. Berlinia grandiflora, Syzygium guineense and Cola laurifolia and finally Acacia seyal and Mitragyna inermis were the best indicators for the Guinean, Sudano-Guinean and Sudanese gallery forest ecotypes, respectively, as suggested by Morel. However, other species such as Pterocarpus santalinoides and Mimosa pigra were not ecotype specific. Trap catches confirmed that G. palpalis and G. tachinoides are predominant in Guinean and Sudanese gallery forests, respectively, and that both species are well represented in the Sudano-Guinean ecotype. Tsetse densities dropped significantly in disturbed Sudano-Guinean and Sudanese gallery forest sites. However, this was not the case for both species in Guinean or for G. tachinoides in half-disturbed Sudanese gallery forest sites, confirming their high resilience to human-made changes. The importance of a detailed consideration of riverine ecotypes when predicting tsetse densities is discussed.

[Representations of mother to child transmission of AIDS, perception of the risk and health information messages in Burkina Faso].

In Burkina Faso, in rural Mossi areas, popular contemporary representations of the transmission of HIV from mother to child are based on the idea that "the disease is in the blood" and that the fetus is conceived by "mixing the blood" of its parents. Infection of the child is seen as inevitable and systematic and is believed to occur in utero. Maternal milk is thought to have the same potential for infection because "milk is blood" but its role in transmission is seen as secondary, with transmission occurring before birth. However, breast feeding is believed to be responsible for the transmission of the disease in two ways: 1) by infected women transmitting the illness to healthy children via their milk and 2) by healthy women becoming infected by breast feeding infants born to infected mothers. The belief that transmission is systematic and the fear that the child will contaminate others leads to the widely held view within the population that no care should be taken of children born to women with AIDS and that such children should be abandoned and left to die. These representations have recently developed in the population based on preexisting beliefs relating to the physiology and role of blood in the transmission of diseases and the health information that has been distributed. Health information messages are largely responsible for the representations described above. Indeed, the description of the modes of HIV transmission in such messages has been based on the simplified statement of the triad, sex, blood and mother-child, with no indication of the relative risks of transmission for each. Hence, this incomplete information, interpreted in terms of popular conceptions about contagion, has resulted in maximal probability being attributed to each of the listed modes of transmission. Health information messages are the principal means of communicating scientific information to the general population. The stakes associated with the quality and correctness of the information supplied are therefore very high. The notion of the risk of transmission and statement of the level of risk are essential to any explanation of the modes of transmission of HIV. These ideas cannot be neglected because they are essential to the correct understanding of transmission and to the logical management of individual risk.

Measles vaccination coverage during poliomyelitis national immunization days in Burkina Faso, 1999.

In 1999, Burkina Faso added measles vaccine during the second round of its poliomyelitis national immunization days (NIDs). A cluster survey was conducted in each of the country's 53 health districts to assess vaccination coverage achieved by the campaign. Forty-four percent of children aged 9-59 months had a documented prior measles vaccination, and 88% were vaccinated during NIDs. Eighty-five percent of children not previously vaccinated received measles vaccine during the campaign. Although routine vaccination coverage varied substantially among children from various socioeconomic groups, the campaign appeared to almost equally reach all groups of children surveyed. Poliovirus vaccine coverage was 90% when measles vaccine was added to the campaign, compared with 88% during the first round. In Burkina Faso, the addition of measles vaccine to poliomyelitis NIDs achieved greater equity in measles vaccination coverage according to a number of socioeconomic factors without compromising the coverage of poliovirus vaccination.

A survey of leprosy impairments and disabilities among patients treated by MDT in Burkina Faso.

Since 1990, Burkina Faso, a West African country, has carried out a national leprosy control program treating with WHO/MDT nearly 12,000 patients between 1990 and 1994. A sample survey of 600 cases among these patients showed that 29.8% were disabled cases. There was a predominance of males, older patients, the multibacillary form of leprosy, and former cases treated with dapsone before MDT. The actual rate increased 8.5% compared to the frequency of disabilities at detection (21.3%). The need for disability care was estimated, respectively, at 24.4% and 5% for primary and secondary grades of disability. These important needs were so great that the authors recommend the planning and initiation of a physical rehabilitation and disability prevention program in this country.

Helicobacter pylori infection in Burkina Faso: an enigma within an enigma.

BACKGROUND: In Burkina Faso, in contrast with high rates of Helicobacter pylori infection from an early age, the prevalence of H. pylori-associated diseases (ulcer and gastric cancer) is low. AIMS: To look for the prevalence of H. pylori in healthy natives of Burkina Faso, both children and adults. METHODS: We studied the prevalence of H. pylori infection in 258 healthy natives of Burkina Faso (70 children aged 6 months-15 years and 188 adults aged 16-65 years), using a serological screening (IgA and IgG H. pylori antibodies). All the studied subjects underwent a questionnaire regarding their life-style, socio-economic status, dietary habits and hygienic sanitary conditions. Data concerning the questionnaire were compared between H. pylori positive and negative subjects. RESULTS: The rates of H. pylori positivity in children were significantly higher than in adults, and in adults the positivity for H. pylori infection decreased with increasing age. The comparison of the questionnaire's data between H. pylori seropositive and seronegative subjects showed that poor socio-economic status and hygienic sanitary conditions were similar in the two groups. Instead, a higher prevalence of H. pylori positivity was observed in subjects belonging to families living in close contact with sheep, because of their labour and agro-pastoral tradition (shepherds and sedentary farmers). CONCLUSION: H. pylori infection in Burkina Faso is acquired early in life and is related not only to some yet well-known risk factors (poor socio-economic and hygienic status), but also to a close contact with sheep. The gradually decreasing H. pylori seropositivity in adult population of Burkina Faso represents an unexplained enigma, which needs further studies.

A survey of gastrointestinal helminths of the common helmet guinea fowl (Numida meleagris galeata) in Burkina Faso.

Guinea fowls in Burkina Faso (Africa) harbored 13 species of helminth parasites. The two most abundant species were Subulura suctoria and Ascaridia numidae, which comprised 89% of the nematodes. The other nematode species (Gongylonema congolense, Eucoleus annulatus, Synhimantus spiralis, Tetrameres fissispina, and Cyrnea parroti) occurred at low levels. Five species of cestodes and one acanthocephalan were also present. It is likely that guinea fowl act as important reservoir hosts of chicken nematodes.

Gastro-intestinal helminths of donkeys in Burkina Faso.

Thirty adult donkeys from Burkina Faso were necropsied and their gastro-intestinal worm burdens counted and determined. The strongylids were the most abundant species with a prevalence of 100% for Strongylus vulgaris. Four species of Strongylus, two of Triodontophorus and six of the Cyathostominae were recovered. All of the animals were also infested with habronematid nematodes, but oxyurid and ascaridid nematodes were found in low numbers. In addition to the nematodes, the paramphistomid trematode Gastrodiscus aegyptiacus and the anoplocephalid cestode Anoplocephala magna occurred in varying numbers. Faecal egg-counts from 131 donkeys ranged between 100 and 9,200 for strongylid eggs.

HIV infection among pregnant women in Burkina Faso: a nationwide serosurvey.

To determine the prevalence of HIV infection among pregnant women in Burkina Faso and to identify factors associated with HIV infection in this population, we performed in 4 antenatal clinics in 4 urban centres located in the centre, the north, the east and the south-west of the country cross-sectional serological surveys between 7 October 1994 and 7 February 1995 using unlinked anonymous HIV screening method. In the towns included in the study more than 94% of pregnant women attend at least 2 antenatal consultations. In each centre all pregnant women attending an antenatal consultation during a 2-week period were invited to take part in a study to measure the prevalence of syphilis. Women with positive syphilis serology were offered treatment free of charge. A total of 1294 pregnant women were recruited into the study. There were no refusals. Thirty-two women (2.5%) had positive syphilis serology. The overall seroprevalence of HIV infection was 8% (95% confidence interval [CI]: 6.6-9.6). There was no evidence that the prevalence of syphilis or HIV infection varied between the 4 towns (P=0.12 and 0.52 respectively). In logistic regression analyses only the presence of syphilis infection was associated with risk of HIV (odds ratio=3.4; 95% CI: 1.4-7.9). The prevalence of syphilis among pregnant women in Burkina Faso is relatively low compared with that of HIV infection. These results suggest that HIV epidemic in Burkina Faso is important and that there is an urgent need to intensify HIV-prevention activities. The need for HIV surveillance in this sentinel population is urgent to follow the course of the epidemic and to measure the impact of interventions. One of the consequences of the high prevalence of HIV infection among pregnant women which requires greater attention in Burkina Faso is the increasing number of children who will be infected with HIV by vertical transmission.
