There are 4 main forms of the disease: visceral leishmaniasis (VL, also known as kala-azar); post-kala-azar dermal leishmania...sis (PKDL); cutaneous leishmaniasis (CL); and mucocutaneous leishmaniasis (MCL). While cutaneous leishmaniasis is the most common form of the disease, visceral leishmaniasis is the most serious and can be fatal if untreated. Additionally, leishmaniasis can be classified as anthroponotic or zoonotic depending on whether the natural reservoir of the parasite is human or animal.
This report updates global epidemiological information on VL and CL to 2015, based on the main indicators published in the GHO, as of 1st September 2017.

Vanquishing violence and vulnerability in humanitarian settings
Background paper for the joint African Union–UNAIDS (in capacity of serving
Chair of H6) high-level side event at the 73rd United Nations General Assembly,
24 September 2018, at UNHQ, Conference Room 3
The goal of this course is to provide participants with the foundational skills needed to begin the development, implementation and ongoing improvement of a congenital anomalies surveillance programme, in particular for countries with limited resources. It focuses on the methodology needed to devel...op either population-based or hospital based surveillance programmes.
A set of congenital anomalies will be used as examples throughout this course. The specific examples used are typically severe enough that they would probably be captured within the first few days after birth, have a significant public health impact and, for some of them, have the potential for primary prevention.

Effective response to an outbreak of COVID-19 requires detection in the very earliest stages of the outbreak when the number of cases is small, and the geographical extent of spread is limited. In order to achieve this, a sensitive surveillance system capable of detecting small scale, unusual events... is necessary.

Prevention, early diagnosis, and effective treatment are essential for the control and elimination of Neisseria gonorrhoeae as a public health problem. Currently, in Latin America and the Caribbean, treatment for gonorrhea infection is largely empiric and based on clinical diagnosis. In the Americas..., the high burden of new N. gonorrhoeae infections (estimated at 11 million new cases a year), the complexity of the disease epidemiology, and in many countries the limited resources, make it difficult to fully understand the burden of disease and the burden of antimicrobial resistance (AMR) in N. gonorrhoeae.
PAHO has developed this document to facilitate the navigation of available guidance and recommendations for N. gonorrhoeae AMR surveillance by public health and health care professionals, at the national and subnational levels, involved in designing, implementing, and/or strengthening AMR surveillance of N. gonorrhoeae and overall surveillance of sexually transmitted infections.

The number of confirmed COVID-19 cases detected and reported in each country is influenced by
many factors including limited access and/or utilization of healthcare and COVID-19 testing, limited
surveillance, lack of knowledge amongst the population about when to seek testing, an asymptomatic pres...entation, and other unknown issues. This is true in all countries of the world, and not Africa specific, however there are factors unique to Africa which may also affect the way the virus behaves there. COVID-19 prevalence data are critical for planning effective mitigation strategies and understandingthe true impact of the disease and relevant intervention measures in Africa, which might be quite different from regions with a different population age distribution or risk factor profile.

The strategy recommends that AU Member States should enhance, where feasible, existing COVID-19 surveillance to include:
Community-based surveillance to detect symptomatic cases early for treatment and to avert viral transmission;
Sentinel surveillance in high-risk populations to detect ...and track both presymptomatic and asymptomatic cases; and
Wastewater surveillance to monitor early environmental signs of virus transmission and identify communities where targeted interventions can be implemented to decrease transmission.

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

This study shows the importance of an integrated entomological and medical surveillance for the evaluation of arboviral disease risk, which is a precondition for designing cost-effective vector control programs.
Maternal mortality has fallen significantly in recent years, especially in countries that have emphasized the prevention of its main causes, such as hemorrhagic and infectious complications and hypertension , including in the Region of the Americas. In its final report on the Plan of Action to Accel...erate the Reduction of Maternal Mortality and Severe Maternal Morbidity, the Pan American Health Organization (PAHO) reported a continuing downward trend in maternal mortality, with an 18.1% reduction in the maternal morbidity ratio during the period 2010-2015 . From a pathophysiological perspective, death events are a common end result of a wide spectrum of complications leading to multi-organ dysfunction. However, there is a group of women in this situation who survive, despite the seriousness of their condition. This high number of patients––who were in serious condition
but did not die––reflects the actual health conditions in an institution or a country. For this reason, there is a need to create indicators to estimate morbidity in women due to diseases and incidents that occur during pregnancy, childbirth, and the puerperium. To this end, we propose conducting epidemiological surveillance of an indicator that includes women who survived after presenting a potentially fatal complication during pregnancy, childbirth, or the puerperium, reflecting quality medical attention and care (5, 6). This indicator
is maternal near-miss (MNM), which refers to extremely severe maternal morbidity––cases of a severity that
brings women very close to the death event. After adjusting the definition to a specific population and time,
MNM is defined as a case in which a woman nearly died, but survived a complication that occurred during
pregnancy, childbirth, or within 42 days of termination of pregnancy

The importance of robust mortality surveillance systems cannot be overstated in an era marked by increasing global health challenges where health threats loom large and population dynamics continue to evolve. Accurate and timely mortality data is essential for identifying trends and detecting emergi...ng health threats, evaluating the impact of interventions, and guiding evidence-based policy decisions.
This framework outlines a holistic approach to strengthening routine mortality surveillance systems, considering the unique contextual factors and challenges faced by African countries. It emphasizes the importance of establishing efficient data collection mechanisms, enhancing data quality and completeness, and promoting data sharing and collaboration among stakeholders.
Moreover, the framework recognizes the pivotal role of technology in the integration of data from fragmented mortality data sources. It highlights the potential of innovative data capture methods, advanced analytics, and real-time reporting systems to enhance mortality data’s accuracy, efficiency, and timeliness.
The continental framework for mortality surveillance aligns with Africa CDC’s mission and strategic goal by serving as a fundamental component in strengthening public health systems, enhancing disease surveillance capacities and capabilities, informing evidence-based policies and interventions, and promoting collaboration and coordination among African countries to address health challenges and improve health outcomes on the continent.
The successful implementation of this framework requires collective commitment and concerted efforts from governments, health institutions, and the international community. We hope this document will serve as a catalyst for transformative change, enabling countries to build resilient mortality surveillance systems that protect public health, save lives, and contribute to evidence-based decision-making.
