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 environmental 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.

Geographical, landscape and host associations of Trypanosoma cruzi DTUs and lineages
Izeta-Alberdi, A.; Ibarra-Cerdena, C.; Moo-llanes, D.; Ramsey,J.
BMC Part of Springer Nature
(2016)
CC
Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms.
...
Under natural conditions, the principal transmission modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

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 caus
...
ed several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid diagnostic 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.

Cervical cancer is the second most common cancer among women worldwide and causes a significant number of deaths in the South-East Asia Region. Nearly 200 000 new cases of cervical cancer occurred in SEA Region Member States in 2008, giving an incidence of almost 25 per 100

000 and a mortality rate of almost 14 per 100 000. Cervical cancer can be prevented by early screening and vaccination. However, due to poor access to screening and treatment services, the vast majority of these deaths occur in women from nine Member States of the South-East Asia Region which account for more than one third of the global burden of cervical cancer.

Overview: Risk communication and community engagement are essential for any disease outbreak response. This is particularly critical during outbreaks of Ebola which may create fear in the public and frontline responders alike due to severe presentat

ion of symptoms, misunderstanding of the causes of illness and high fatality rates. This document outlines some of the key considerations for risk communication and community engagement response to Ebola outbreak in Democratic Republic of the Congo.
Ebola outbreaks have been associated with misinformation and false rumours. In the context of RCCE, rumours refer to unsubstantiated information, claims or beliefs about what is causing the disease or how it can be treated/cured. If not proactively addressed in culturally appropriate ways, misinformation and rumours can lead to the further rapid spread of the disease and unnecessary deaths, severe disease, suffering, and societal and economic loss.
The publication includes a 'Rumour Tracking Tool' (Annex II).
