The study on health facility preparedness for cholera outbreak response in Cameroon evaluates the ability of healthcare facilities in four cholera-prone districts to manage cholera outbreaks. The findings highlight significant weaknesses, including limited surveillance systems, inadequate access to ...water, poor sanitation, and lack of essential medical supplies such as Oral Rehydration Solution (ORS) and cholera case management guidelines. Many health facilities also lacked trained personnel and proper waste disposal systems, increasing the risk of disease spread within healthcare centers. The study underscores the urgent need for improved hygiene infrastructure, better training, and resource allocation to enhance outbreak response and reduce cholera-related mortality.

AVADAR is a mobile sms-based software application designed to improve the quality and sensitivity of Acute Flaccid Paralysis (AFP) surveillance by health workers and key informants within hospital facilities and local communities.
The idea is simple: Health workers visit remote villages to check if... local inhabitants have any symptoms of a range of life-threatening infectious diseases, including polio and measles. Then, with the mobile app, they quickly and easily alert WHO.
The AFP video component was developed by World Health Organization (WHO) and eHA, and the software design component was handled by Novel-T. To date, eHA has translated the app into 17 languages.
Informant Selection & Capacity Building
The selection of informants (including health workers) was led by the WHO and each country’s Ministry of Health team. Once selected, screening and training was jointly conducted by WHO, the Ministries of Health, and eHealth Africa team.
In several countries, “special informants” with limited literacy participate in the project via a simplified version of the app that only requires a “yes” or “no” response to having seen a child with AFP symptoms

The Manual for Parasitological Surveillance in Prevention of Reintroduction or Re-establishment of Malaria in Sri Lanka (2019) provides guidelines to health professionals on how to conduct effective malaria surveillance to prevent the reintroduction of the disease in Sri Lanka, which was certified m...alaria-free in 2016.
The manual outlines strategies for active and passive case detection, laboratory diagnosis, case investigation, foci investigation, and follow-up measures. It emphasizes targeted screening of high-risk populations, including travelers and migrant workers, and explains the importance of prompt reporting, accurate parasitological confirmation, and coordination between healthcare levels. The overall goal is to maintain Sri Lanka’s malaria-free status by ensuring early detection and rapid response to any imported or locally suspected malaria cases.

This protocol provides an approach for public health authorities and investigators at all levels to plan for and conduct investigations of nonseasonal influenza and other emerging respiratory diseases and provides tips and reminders for linking the information from the investigation with risk assess...ment. The disease etiology is not always known at the onset of the event; therefore, this protocol focuses on important but broadly applicable steps that should be undertaken in the investigation of an acute respiratory disease event, especially those occurring at the animal–human interface.

Le choléra reste une menace mondiale pour la santé publique et un indicateur clé du
manque de développement social. La transmission du choléra est étroitement liée à
l’accès insuffisant à l’eau potable et à l’assainissement. Les zones typiques à risque sont
notamment les bido...nvilles périurbains et les zones rurales où les infrastructures de base
ne sont pas disponibles, ainsi que les camps de personnes déplacées ou de réfugiés où
les conditions de vie et l’accès à l’eau et aux systèmes d’assainissement sont insuffisants.
En 2015, plus de 170 000 cas et 1 300 décès (TL : 0,8 %) ont été signalés à l’OMS dans
42 pays, dont 41 % en Afrique 37 % en Asie et 21 % en Haïti. C
