Buruli ulcer is a disease caused by the environmental pathogen Mycobacterium ulcerans that affects skin and soft tissue. It was first described in Australia in 1948 and has been reported in several sub-Saharan African countries since the late 19th century. The disease mainly affects children in rura...l areas and causes lesions and ulcers that can lead to disability if not treated. Recent research has identified a toxin produced by M. ulcerans that may be responsible for the disease's pathogenesis. Efforts are ongoing to understand transmission and develop effective control strategies, including through training of medical professionals and increased detection and treatment of cases.

The technical note by the Global Task Force on Cholera Control (GTFCC) discusses the use of Oral Cholera Vaccines (OCVs) for international workers and travelers in cholera-affected areas. It reviews the effectiveness of WHO-prequalified vaccines (Dukoral®, Shanchol™, and Euvichol®), emphasizing ...their role in preventing infection and reducing transmission risks.
The document highlights concerns about travelers contracting cholera in endemic regions and potentially spreading the disease upon returning home. While the overall risk is considered low, certain groups, such as humanitarian workers and travelers to high-risk areas like South Asia, face a higher exposure.
Recommendations include vaccination for emergency and relief workers who may come into direct contact with cholera patients or contaminated environments. However, routine vaccination for general travelers is not widely recommended. The note also calls for better surveillance and studies to assess the potential of vaccines in preventing international transmission.

In the 126 years since it was first described, scientists have learned a great deal about Buruli ulcer, (an ulcerating skin infection caused by the environmental bacterium, Mycobacterium ulcerans), including how to treat it. Yet, there is 1 question about this neglected tropical disease that has rem...ained unanswered: how is M. ulcerans transmitted to humans? In southeastern Australia, where Buruli ulcer is endemic and cases are increasing, researchers are putting together the M. ulcerans transmission puzzle. The more they learn, the better equipped they will be for managing infections.

This is a case-ascertained prospective investigation of all identified health care contacts working in a health care facility in which a laboratory confirmed 2019-nCoV infected patient (see 2.2 Study population) receives care. Note that this study can be done in health care facilities at all 3 level...s of a health system – not just in hospitals. It is intended to provide epidemiological and serologic information which will inform the identification of risk factors 2019-nCoV infection among health care workers.
There are three primary objectives of this investigation among health care workers in a health care setting where a 2019-nCoV infected patient is being cared for:
To better understand the extent of human-to-human transmission among health care workers, by estimating the secondary infection rate1 for health care worker contacts at an individual level.
To characterize the range of clinical presentation of infection and the risk factors for infection among health care workers.
To evaluate effectiveness of infection prevention and control measures among health care workers
To evaluate effectiveness of infection prevention and control programmes at health facility and national level

Buruli ulcer (BU), the second most common mycobacterial disease in West Africa, is a necrotizing skin disease that can lead to high morbidity in affected patients. The disease is caused by Mycobacterium ulcerans (MU), whose major virulence factor is mycolactone. Although early infection can be treat...ed with antibiotics, an effective preventative strategy is challenging due to unknown reservoir(s) and unresolved mode(s) of transmission.

According to WHO, infection prevention and control (IPC) is a scientific approach and practical solution designed to prevent harm caused by infection to patients and health workers. It is grounded in infectious diseases, epidemiology, social science and health system strengthening. IPC occupies a un...ique position in the field of patient safety and quality universal health coverage since it is relevant to health workers and patients at every single health-care encounter. Poor WASH and IPC lead to health acquired infections, transmission of diseases from health facilities to communities and increased use of antibiotics and exacerbate outbreak and spread of infections- in this case- COVID- 19. On the contrary, effective IPC reduces hospital-acquired infections by at least 30% (WHO 2016).

Le Plan Stratégique Multisectoriel d’Élimination du Choléra en République Démocratique du Congo (2013-2017) vise à réduire l’incidence du choléra à moins d’un cas pour 100 000 habitants. Ce plan repose sur une approche multisectorielle, combinant santé, eau, hygiène et assainissemen...t pour enrayer la transmission du choléra.
Il identifie trois types de zones : zones sources (A), zones épidémiques (B) et zones de diffusion (C), chacune nécessitant des interventions adaptées. Les stratégies incluent l’amélioration des infrastructures d’eau potable et d’assainissement, la surveillance épidémiologique, la prévention, la prise en charge médicale et la coordination des actions.
Malgré des progrès dans certaines régions, la mise en œuvre du plan a rencontré des défis, notamment en raison du manque de financements et de la persistance de foyers endémiques dans l'Est du pays. Une coordination nationale et internationale est essentielle pour mobiliser les ressources et atteindre l'objectif d'élimination du choléra en RDC.

Planning for public health emergencies should ensure that capabilities developed during previous emergencies are maintained, incorporated, and put into practice when a new event of public health concern arises. Investments in pandemic preparedness lead to more rapid detection and a stronger response... to public health threats, thereby shielding communities from the debilitating social and economic effects of epidemics and pandemics. The Pan American Health Organization (PAHO) recognizes the efforts of countries in the Region of the Americas to develop and/or strengthen their respiratory pathogen pandemic plans. PAHO supports planning activities with tools and expertise, aligning these efforts with the Preparedness and Resilience for Emerging Threats (PRET) initiative. The PRET initiative is an innovative approach to improving disease pandemic preparedness. It recognizes that the same systems, capacities, knowledge, and tools can be leveraged and applied for groups of pathogens based on their mode of transmission (respiratory, vector-borne, foodborne etc.). The PRET initiative incorporates the latest tools and approaches for shared learning and collective action established during the COVID-19 pandemic and other recent public health emergencies.

The conditionality of this recommendation is largely driven by the current higher unit cost of pyrethroid-PBO ITNs compared
to pyrethroid-only LLINs and therefore the uncertainty of their cost-effectiveness. Furthermore, as PBO is less wash-resistant
than pyrethroids, its bioavailability declines ...faster over the three-year estimated life of an ITN; therefore, the added impact of
pyrethroid-PBO ITNs over that of pyrethroid-only LLINs may decline over time. The evidence comes from two sites in
eastern Africa with pyrethroid resistance and not from other geographies where transmission levels and vector characteristics
may vary. PBO acts by inhibiting certain metabolic enzymes, primarily oxidases, and so are likely to provide greater protection
than pyrethroid-only LLINs where mosquitoes display mono-oxygenase-based insecticide resistance mechanisms.

La résistance aux antimicrobiens Esurvient lorsque les micro-organismes (bactéries, champignons, virus et parasites) évoluent quand ils sont exposés à des médicaments antimicrobiens (comme les antibiotiques, les antifongiques, les antiviraux, les antipaludiques et les anthelminthiques).
On ap...pelle parfois «super bactéries» celles qui développent une résistance aux antimicrobiens, mais cela concerne tous les micro-organismes.
En conséquence, les médicaments perdent leur efficacité et les infections persistent dans l’organisme, augmentant le risque de transmission à d’autres personnes.
