The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

Internationally, there is a growing concern over antimicro-bial resistance (AMR) which is currently estimated to ac-count for more than 700,000 deaths per year worldwide. If no appropriate measures are taken to halt its pro-gress, AMR will cost approximately 10 million lives andabout US$100 trillion... per year by 2050. In contrast tosome other health issues, AMR is a problem that con-cerns every country irrespective of its level of incomeand development as resistant pathogens do not respect borders.Despite the threat presented by AMR, the 2014 WorldHealth Organization (WHO) and the recent O’Neill re-port describe significant gaps in surveillance, standardmethodologies and data sharing. The 2014 WHOreport identified Africa and South East Asia as the regions without established AMR surveillance systems.

This updated step by step guide aims to assist the ministries of health (MoHs) in developing the national action plans for noma prevention and control, with a view to sustainably reducing the incidence of noma as a public health problem through programmes that are fully integrated with national heal...th planning, strengthening of primary health care (PHC) and attainment of universal health coverage (UHC).

Noma (cancrum oris) is a severe gangrenous disease of the mouth and face. It mostly affects children between the ages of 2 and 6 years living in extreme poverty. In addition to the known factors such as malnutrition, lack of vaccination in children and poor oral hygiene, several social and environme...ntal factors such as maternal malnutrition and close spacing of pregnancies that result in offspring with increasingly weakened immune systems are potentially related to the onset of the disease.
The aim of this guide is to assist the ministries of health (MoHs) to identify a general goal to be attained by the end of five years, with a view to sustainably reducing the incidence of noma as a public health problem through programmes that are fully integrated with national health planning, strengthening of primary health care (PHC) and attainment of UHC.

The main purpose of the meeting was to review tsetse control tools, activities and their contribution to the elimination of gHAT and the monitoring thereof. Seven endemic countries provided reports on recent and ongoing vector control interventions at the national level (Angola, Cameroon, Côte d’...Ivoire, Chad, Democratic Republic of the Congo, Guinea and Uganda). Country reports focused on the in situations implementing and supporting vector control activities, the tools and the approaches in use, the coverage of the activities in space and time and their impacts on tsetse populations. Future perspectives for vector control in the respective countries were also discussed, including opportunities and challenges to sustainability.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

The major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reported as an emerging disease in different regions of Af...rica [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.

A – Z of Rabies – A guide to the world´s deadliest disease
Mission Rabies
The Fifty-first World Health Assembly adopted resolution WHA51.11 in 1998, which targets the
global elimination of trachoma as a public health problem by 2020 (1). The strategy recommended
to achieve that goal is encapsulated by the acronym “SAFE”, which represents: Surgery for
individuals wi...th trachomatous trichiasis (TT; the late blinding stage of trachoma); and Antibiotics,
Facial cleanliness and Environmental improvement (2). The A, F and E interventions are delivered to
entire districts in which active (inflammatory) trachoma is common in order to treat ocular infection
with Chlamydia trachomatis, the causative organism of trachoma, and sustainably reduce its
transmission.

En 1998, la Cinquante-et-Unième Assemblée mondiale de la Santé a adopté la résolution
WHA51.11 qui vise l’élimination mondiale du trachome en tant que problème de santé publique
à l’horizon 2020 (1). La stratégie recommandée pour atteindre cet objectif est récapitulée dans
le sig...le « CHANCE » qui signifie CHirurgie pour les personnes atteintes de trichiasis
trachomateux (TT – le dernier stade cécitant du trachome) ; Antibiothérapie, Nettoyage du
visage et Changements Environnementaux (2). Les interventions relatives aux volets A, N et CE
sont menées dans des districts entiers dans lesquels les cas de trachome évolutif
(inflammatoire) sont courants, dans le but de traiter les infections oculaires dues à Chlamydia
trachomatis, l’agent pathogène à l’origine du trachome, et de réduire durablement sa
transmission.
