The STEPS survey of noncommunicable disease (NCD) risk factors in Zambia was carried out from July to September 2017. Zambia carried out Step 1, Step 2 and Step 3. Socio demographic and behavioural information was collected in Step 1. Physical measurements such as height, weight and blood pressure w...ere collected in Step 2. Biochemical measurements were collected to assess blood glucose and cholesterol levels in Step 3. The survey was a population-based survey of adults aged 18-69. A multi-stage cluster sample design was used to produce representative data for that age range in Zambia. A total of 4,302 adults participated in the survey. The overall response rate was 74% for Step 1 and 2 and 65% for Step 3. A repeat survey is planned for 2022 if funds permit.

Leishmaniasis is a vector-borne disease with a broad global distribution and an increasing number of recorded cases worldwide. However, it is still one of the world's most neglected diseases. Over the last decades, the disease has been found to expand geographically with a global increase of cases o...f visceral and cutaneous leishmaniasis increasing the public health problems associated with the disease epidemics. The reported range expansion of the diseases has been associated with range expansions of vector populations in response to climate change. Leishmaniasis is caused by protozoan parasites of the genus Leishmania. The transmission can either be zoonotic and/or anthroponotic through the bite of an infected female phlebotomine sandfly. In Eurasia and Africa, all vector-competent sandfly species belong to the genus Phlebotomus. Cutaneous leishmaniasis (CL) is the most common form of leishmaniasis. In the ‘old world’, it is caused by five currently recognized Leishmania species: L. major, L. tropica and L. aethiopica (being main causative parasites) as well as L. infantum and L. donovani. Visceral leishmaniasis (VL), another common and more severe form of leishmaniasis, is only associated with the Leishmania species L. infantum and L. donovani. The specific Leishmania species cause different clinical symptoms in humans.

Urogenital schistosomiasis is a common neglected tropical disease in many rural communities in African countries, with patches of infection in the Eastern Mediterranean Region. Globally, an estimated 239 million people are currently infected, with burden estimated at more than 3.5 million disability...-adjusted life years (DALYs). In many endemic areas, severely infected individuals may suffer fibrosis of the bladder, kidney damage, bladder cancer, and death if untreated. This, however, depends on several factors such as host-parasite genetics, degree and length of exposure, intensity of infection, host immune response to the parasites, and coinfections with other tropical diseases such as malaria and HIV-1.

There is widespread recognition of the growing threat of infectious disease epidemics and pandemics spreading across countries or continents—especially following the recent Ebola and COVID-19 pandemics. Vulnerable groups (including children, older adults, ethnic minorities and other at-risk group...s) have disproportionately borne the brunt of significant health, social, and economic effects of these epidemics and pandemics, with varying degrees of support received depending on the context. While many argue that communities should or need to play a critical role in supporting and leading preparedness and response efforts, work still needs to be done to engage them effectively. In many instances, modes of engagement with communities—especially by state authorities–have come too late, often as an afterthought are not adequately thought through and have undermined public trust in and support for, disease prevention and control measures

The National Integrated Comprehensive Cholera Prevention and Control Plan (2017-2022) outlines Uganda's strategy to reduce cholera cases and mortality by 50% by 2022. The plan focuses on improving access to clean water, sanitation, and hygiene (WASH), strengthening disease surveillance, enhancing ca...se management, and implementing oral cholera vaccination (OCV) in high-risk areas. It emphasizes multi-sectoral collaboration, involving government agencies, NGOs, and local communities to ensure a sustainable response. Key interventions include community engagement, improved health services, and better outbreak preparedness, aiming for long-term cholera elimination in Uganda.

As the number of transboundary pest and animal and foodborne disease outbreaks rises, so does the number of people who are chronically hungry due to these and other factors. The correlation can be explained by the link between our health and that of the planet. We rely on land and sea for the produc...tion of safe and quality foods for our daily nourishment. Pests and disease epidemics negatively impact the quality, quantity and safety of our food sources, and cripple economic growth and efficiencies in production. Furthermore, the epidemic and endemic levels of the pathogens and disease vectors can be difficult to control. This is why FAO stresses and promotes the special efforts required for cost-effective preventive measures rather than the more expensive control, disinfestation, treatment and disposal measures. When preventive measures are late or difficult, preparedness and contingency plans must be in place to enable rapid response. Early warning systems, based on close monitoring, surveillance, and timely reporting are fundamental to warn and empower communities to safeguard their livelihoods and assets by enhancing disease and pest prevention measures and for government services to take immediate measures to protect communities and national economies.

Lessons learned from recent public health events such as the COVID-19 pandemic, Ebola virus disease, Zika virus disease outbreaks, and other public health threats, including earthquakes and floods, have highlighted the need for countries to continuously develop, strengthen, and maintain capacities r...equired under the International Health Regulations (2005) (IHR (2005)).
Developing capacities for health security in a country requires the engagement of public and private entities across a broad range of sectors, including human and animal health, agriculture, environment, finance, security, emergency management, education, and transportation. The World Health Organization (WHO) is mandated through various resolutions, decisions, and reports of the World Health Assembly, and through the IHR (2005), to provide technical guidance and support to its Member States in developing, strengthening, and maintaining their health systems, including capacities required under the IHR (2005).
For countries to better prevent, prepare for, detect, notify, respond to, and recover from public health emergencies, they must build and maintain IHR core capacities and support the strengthening of health emergency prevention, preparedness, response, and resilience (HEPR) capacities. National Action Plans for Health Security (NAPHS), as capacity development plans, provide the tasks and resources needed to ensure adequate capacities are in place to prevent, detect, respond to, and recover from public health events in a sustainable manner. Investing in the resilience of these capacities within national health systems at national and local levels not only improves national health security but also helps safeguard economic, social, and political developments.

This guidance note aims to ensure continuity of case management service provision as well as appropriate response to cases associated with the disease during the COVID-19 crisis in Myanmar. Outlined below are priority areas that Child Protection Case Management agencies should focus on
For several years, agencies supporting preparedness and response to cholera outbreaks have supplied medicines and medical devices through the Interagency Diarrhoeal Disease Kits (IDDK).
In an effort to better align the presentation and content of the kits to field needs, the composition of the ch...olera kits has been reviewed by WHO and its partners in 2015 and again in 2020. The content of all modules have been slightly revised with no changes except for the cholera laboratory check list.
The revised cholera kits 2020 are designed to help prepare for a potential cholera outbreak and to support the first month of the initial response for 100 cases. The overall package consists of six different kits, each divided in several modules.

Asthma is the most common chronic disease in children globally. The Global Asthma Network (GAN) Phase I study aimed to determine if the worldwide burden of asthma symptoms is changing.
This updated cross-sectional study used the same methods as the International study of Asthma and Allergies in Chi...ldhood (ISAAC) Phase III. Asthma symptoms were assessed from centres that completed GAN Phase I and ISAAC Phase I (1993–95), ISAAC Phase III (2001–03), or both. We included individuals from two age groups (children aged 6–7 years and adolescents aged 13–14 years) who self-completed written questionnaires at school. We estimated the 10-year rate of change in prevalence of current wheeze, severe asthma symptoms, ever having asthma, exercise wheeze, and night cough (defined by core questions in the questionnaire) for each centre, and we estimated trends across world regions and income levels using mixed-effects linear regression models with region and country income level as confounders.
Overall, 119 795 participants from 27 centres in 14 countries were included: 74 361 adolescents (response rate 90%) and 45 434 children (response rate 79%). About one in ten individuals of both age groups had wheeze in the preceding year, of whom almost half had severe symptoms. Most centres showed a change in prevalence of 2 SE or more between ISAAC Phase III to GAN Phase I. Over the 27-year period (1993–2020), adolescents showed a significant decrease in percentage point prevalence per decade in severe asthma symptoms (–0·37, 95% CI –0·69 to –0·04) and an increase in ever having asthma (1·25, 0·67 to 1·83) and night cough (4·25, 3·06 to 5·44), which was also found in children (3·21, 1·80 to 4·62). The prevalence of current wheeze decreased in low-income countries (–1·37, –2·47 to –0·27], in children and –1·67, –2·70 to –0·64, in adolescents) and increased in lower-middle-income countries (1·99, 0·33 to 3·66, in children and 1·69, 0·13 to 3·25, in adolescents), but it was stable in upper-middle-income and high-income countries.
Trends in prevalence and severity of asthma symptoms over the past three decades varied by age group, country income, region, and centre. The high worldwide burden of severe asthma symptoms would be mitigated by enabling access to effective therapies for asthma.

Mental disorders are a leading cause of the global burden of disease, and the provision of mental health services in developing countries remains very limited and far from equitable. Using the Creditor Reporting System, we estimate the amounts and patterns of development assistance for global mental... health (DAMH) between 2007 and 2013. This allows us to examine how well international donors have responded to calls by global mental health advocates to scale up evidence-based services. Although DAMH did increase between 2007 and 2013, it remains low both in absolute terms and as a proportion of total development assistance for health (DAH). The average annual DAMH between 2007 and 2013 was US$133.57 million, and the proportion of DAH attributed to mental health is less than 1%. Approximately 48% of total DAMH was for humanitarian assistance, education, and civil services. More annual DAMH was channelled into the nonpublic sector than the public sector. Despite an expanding body of evidence suggesting that sustainable mental health care can be effectively integrated into existing health systems at relatively low cost, mental health has not received significant development assistance.
