It was to assess reaching of the leprosy elimination threshold (one case per 10,000 inhabitants) in Burkina Faso. We drew lots for the villages in ten provinces among which five had the highest prevalence rates of leprosy in 1996 and five had the lowest prevalence rates. We added a leprosy elimination monitoring to the survey. This monitoring consisted of visits to the health centers covering the 30 villages. We interviewed and clinically examined 33 cases of leprosy in treatment in those health centers. We found fifty-one patients of leprosy in visited villages. The prevalence rate of leprosy (6.74 per 10,000 inhabitants) was twice higher than the prevalence rate registered in the same villages. We detected 28 new cases of leprosy during the survey. Proportion of hidden cases of leprosy were 54.9%. We estimated geographical coverage of MDT at 75% in the 10 provinces. Eight of the 27 visited health centers (29.6%) did not get sufficient supply. The cure rate has fallen from 93 to 73 per cent between 1992 and 1997. Our results show that leprosy elimination threshold is not reached in Burkina Faso. Leprosy control activities that were declining during the last five years need to be reinforced.

Formerly, this training was offered entirely at the Marchoux Institute. It was aimed at leprosy control workers administering dapsone monotherapy within the framework of vertically integrated programmes. With the introduction of treatment programmes using multidrug therapy, leprosy control was integrated into the comprehensive health services. This change in approach dramatically increased the need for training and made it necessary to adapt the training offered by the Marchoux Institute. Since 1990, the Marchoux Institute has targeted doctors in training and health care staff at the supervisory level. The rise in the number of health agents to be trained has led to the arrangement of short-term training courses in the States concerned, with the participation of facilitators from the Marchoux Institute.

A disability survey was conducted in April 1996 with a half-randomized sample of five hundred patients. This survey showed that 28.73% of the patients had got grade two disabilities in WHO scale. 12.9% of the non disabled patients at detection had developed leprosy impairments during or after treatment. Plantar ulcers (12.2% of the patients) appeared very frequent comparatively to the findings of a similar survey in Burkina Faso in 1995 (0.9% of plantar ulcers). With these results, the authors estimated the needs for disabilities care to enable the reinforcement of the prevention of disabilities and physical rehabilitation (POD and PR) in Ivory Coast.

We conducted a comparative study of passive and active case finding of leprosy in this district in 1997. In May and June, a mobile team realized active case finding by visiting 32 villages of more than 1000 inhabitants. For 12 months, peripheral health center nurses did passive detection after information and education sessions about the signs of leprosy in the other 37 main villages of Kita. The active detection rate (4.31 per 10,000) was threefold higher than the passive rate (1.5 per 10,000) and allowed us to find earlier cases of leprosy. Active case finding identified children and single-lesion disease; the passive method did not. Cost for finding a new case was estimated at 72 US$ by mobile team detection and 36 US$ by passive case finding. Although the active method looked more expensive than the passive one, it was the only effective strategy to detect leprosy patients in remote and difficult-to-access areas. Based upon the results of the study, a flow chart is proposed for the choice of case-finding method when designing a leprosy elimination program.

The aim of the study was to assess the extent to which leprosy causes physical disability in Mali. One area was rural (Circle of Bougouni), the other urban (Bamako District). We used a cluster sampling method, with 500 households selected for study in each of the two areas. All members of the households randomly selected were included in the study. For all survey sites, the number of households was proportional to the number of inhabitants. The total study population was 8,175, including 172 cases of physical handicap, 76 in Bamako and 96 in Bougouni. The prevalence of physical handicap was 21 per 1,000 inhabitants (25.3 per 1,000 in rural areas and 17.3 per 1,000 in the city). The difference in the prevalence of physical handicap between the two areas was statistically significant (p = 0.01). Ten per cent of the disabilities were caused by leprosy. The most common causes of disability other than leprosy were trauma and poliomyelitis. Leprosy mostly caused disabilities in rural areas. In both areas, leprosy caused more disabilities in men and boys (64% of cases) than in women and girls. The frequency of disabilities caused by leprosy increased with age, whereas the frequency of handicaps with other causes decreased with age. This study shows that leprosy is still a major cause of disability in countries in which it is endemic, such as Mali. Disability prevention measures and physical rehabilitation programs should be incorporated into the national program for the elimination of epilepsy.

We define as endemic any health district with BU patients positive by PCR, whether or not positive on a Ziehl-Neelsen (ZN) test, culture or histologic sample. A district is defined as suspected to be endemic when it is a historical BU area, has BU clinical cases and/or patients with positive ZN, but negative PCR. Of the 515 health districts in the DRC, 17 were found to be endemic (3%) and 26 suspected to be endemic (5%). In most cases, former focal areas, described before 1974, remain currently active. New focal points were found along the Kwango River in the province of Bandundu. We also discovered the extension of former BU focal areas to neighboring health districts in the provinces of Bas-Congo, Bandundu, and Maniema. The need for diagnostic confi...

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.

To overcome this, the World Health Organization (WHO) encourages endemic countries to run campaigns for the elimination of leprosy by circulating educational messages and mobilizing the medical community for early screening of cases. The aim of our study was to identify the motives for consultation with high predictive value for the diagnosis of leprosy and to determine the late diagnosis factors and hence assist the staff on site to improve the results of their leprosy elimination campaigns. Patients and methods: The study consisted, during the second trimester of 1999, in interviewing all the patients consulting for the first time the Marchoux Institute or the units screening for leprosy in the Bamako area. The interview recorded the motives for consultation, the delay before consulting and the reasons for late consulting. To assess their positive predictive value, the motives for consultation were related to the diagnosis retained (leprosy or not). Results: One thousand one hundred and seventy seven patients were interviewed. The motive for consulting, "suspected leprosy", scored the highest positive predictive value (PPV) (80 p. 100): 12 cases of leprosy were diagnosed by 15 consultants having suspected leprosy. Neurological problems were the second motive for consultation (PPV=61.9 p. 100). The most frequent motive for consultation was spots or "macules" (20 p. 100 of consultations), but only provided a positive predictive value of 19 p. 100. Prior consultations and non-specialized treatments were identified as factors of delay in diagnosing leprosy (P<0.001). Conclusions: Diagnosis of leprosy cannot be based on the motives for dermatological consultation alone. The macules are the most apparent signs, but of low predictive value. Nevertheless, they are an early but non-specific sign of leprosy and are often neglected by the patient. Other than macules, attention must be paid to the neurological signs (dysesthesia, motor disorders) when screening for leprosy. These signs may appear early on, or be observed at a late stage in the progression of the disease.

The purpose of this work was to determine whether changes in the epidemiology, clinical and bacteriological patterns occurred among patients with leprosy treated at the Marchoux Institute in 1988 and in 1997. We conducted a descriptive cross-sectional study, reviewing retrospectively all files of patients with leprosy seen in 1988 in comparison with a prospective series of leprosy patients seen in 1997. Only new cases of leprosy, prior to treatment and with skin and/or nervous lesions irrespective of the bacilloscopy results, were included in the two series. We included 93 patients among 246 patient files in 1988. There were 119 new cases in 1997. The following variables showed changes: mean delay to consultation (41.2 months in 1988 versus 26.1 months in 1997; patient's suspicion of having leprosy (93 patients in 1988 versus 22 in 1997); notion of contact (35 cases in 1988 versus 45 in 1997).

This implementation from 1983 to 1993 can be divided in two phases: 1983-1987: introduction phase by pilot projects; 1988-1993: extension phase by national leprosy control programmes. During the ten years, MDT coverage rose to 68%, leprosy prevalence rate widely decreased (40.71 to 6.56 per 10,000), while annual detection rate weakly varied (1.89 to 1.26 per 10,000). Factors influencing this evolution of leprosy are brought out and recommendations are made about strategies to be developed for leprosy control up to year 2000.

Consequently, all policy makers and health workers urgently need to be trained and to access the most credible information to contain and mitigate its impact. While the need for rapid training and information dissemination has increased, most of Africa is implementing public health social and physical distancing measures. Responding to this context requires broad partnerships and innovative virtual approaches to disseminate new insights, share best practices, and create networked communities of practice for all teach, and all learn. The World Health Organization (WHO)-Africa region, in collaboration with the Extension for Community Health Outcome (ECHO) Institute at the University of New Mexico Health Sciences Center (UNM HSC), the West Africa college of nurses and the East Central and Southern Africa college of physicians, private professional associations, academia and other partners has embarked on a virtual training programme to support the containment of COVID-19. Between 1st April 2020 and 10th July 2020, about 7,500 diverse health professionals from 172 locations in 58 countries were trained in 15 sessions. Participants were from diverse institutions including: central ministries of health, WHO country offices, provincial and district hospitals and private medical practitioners. A range of critical COVID-19 preparedness and response interventions have been reviewed and discussed. There is a high demand for credible information from credible sources about COVID-19. To mitigate the “epidemic of misinformation” partnerships for virtual trainings and information dissemination leveraging existing learning platforms and networks across Africa will augment preparedness and response to COVID-19.

It is actually the handicap and disability from which most patients suffer and which concern populations. The number of persons suffering from such handicaps worldwide has been estimated at 4 million. Therefore, the main goal is to gradually integrate the activities of the prevention of disabilities and physical rehabilitation programme (PIRP) into the national leprosy control programme (PNL). The persons involved in the implementation of the programme outline the activities planned under the PIRP, detailed objectives, priorities, the means by which they will be implemented, the content of training programmes, assessment criteria and documents available.

Mapping is a prerequisite for effective implementation of interventions against neglected tropical diseases (NTDs). Before the accelerated World Health Organization (WHO)/Regional Office for Africa (AFRO) NTD Mapping Project was initiated in 2014, mapping efforts in many countries were frequently carried out in an ad hoc and nonstandardized fashion. In 2013, there were at least 2,200 different districts (of the 4,851 districts in the WHO African region) that still required mapping, and in many of these districts, more than one disease needed to be mapped. During its 3-year duration from January 2014 through the end of 2016, the project carried out mapping surveys for one or more NTDs in at least 2,500 districts in 37 African countries. At the end of 2016, most (90%) of the 4,851 districts had completed the WHO-required mapping surveys for the five targeted Preventive Chemotherapy (PC)-NTDs, and the impact of this accelerated WHO/AFRO NTD Mapping Project proved to be much g...

In 2013, there were at least 2,200 different districts (of the 4,851 districts in the WHO African region) that still required mapping, and in many of these districts, more than one disease needed to be mapped.
