Cholera is an acute gastrointestinal infection caused by the bacterium Vibrio Cholerae serogroup O1 or O139, and is often linked to unsafe drinking water, lack of proper sanitation and personal hygiene. It adversely affects mostly the poor and vulnerable populations in countries, which are already d

eprived of proper health facilities and conducive environmental conditions. The disease spreads through oro-fecal transmission by the ingestion of contaminated food or water or by person-to-person contact. It has a short incubation period of 2 hours to 5 days and the number of affected cases can rapidly increase across large regions. Cholera is a significant threat to global public health leading to an estimated 3-5 million cases per year worldwide, with an annual toll of 100,000 deaths. The disease was first reported in 1817 from the Ganges Delta of India and since then the ongoing 7th pandemic has emerged from Indonesia, reached Africa in 1970 and Somalia happens to be one of the early affected countries. Over the past few decades,
Somalia has witnessed the occurrence of repeated AWD/Cholera disease outbreaks that have caused high morbidity and mortality across the country.

In 2024, we need US$1.5 billion to provide live-saving health care to millions of people in emergencies. An alarming combination of conflict, climate-related threats and increasing economic hardship mean an estimated 166 million people require health assistance.
A major problem facing the world is how to build peace following the ravages of increasingly protracted armed conflict. Armed conflicts leave behind shattered, divided societies that are at risk of repeating cycles of violence, and therefore need concerted peacebuilding efforts. Conflicts also take

One in five people who live in a war zone will likely develop a mental disorder, and many others suffer from painful everyday stresses associated with multiple losses, family separation, gender-based violence (GBV), disability, climate change and ongoing insecurity, among other issues.

pplied to implement the International Health Regulations 2005 (IHR) and strengthen health emergency prevention, preparedness, response and resilience capacities.
The first edition of the benchmarks was published in 2019 to support countries in developing, implementing and documenting progress of national IHR or health security plans (e.g. national action plan for health security (NAPHS), national action plan for emerging infectious diseases, public health emergencies and health security and other country level plans for health emergencies). The tool has been updated to incorporate lessons from COVID-19 and other health emergencies, to align with the updated IHR monitoring & evaluation framework (IHR MEF) tools and the health systems for health security framework, and to support strengthening health emergency prevention, preparedness, response and resilience (HEPR) capacities and the Preparedness and Resilience for Emerging Threats (PRET) initiative.

In this version of the compendium, each guidance is coded using the International Classification of Health Interventions (ICHI).
The compendium provides a systematic compilation of published guidance from WHO and other UN organizations on health and environment. Guidance on policies and actions a
...
s well as awareness raising and capacity building interventions is presented for all major areas of health and environment. Guidance referring to priority settings for action such as cities and other urban settlements, housing, workplaces and health care facilities is also listed. For greater practical relevance, each guidance is classified according to principally involved sectors, level of implementation and instruments for implementation.
The compilation of guidance for each area of health and environment or priority setting for action is accompanied, as available, by information on main sources, exposure assessment and existing guideline values. Important tools and further resources are presented alongside.
This compilation of published guidance on health and environment highlights that a large number of actions across main topics of health and environment, concerning various sectors, and applicable to various levels are available to improve health and reduce environmental risks. This compendium is intended to serve as a repository and easy-to-use and useful resource for decision and policy makers in health and environment at various levels.

Background
Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a
...
t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity.
Methods
We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction.
Results
We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence).
Conclusions
Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings.

Mental health problems are common and cause great suffering to individuals and communities around the world. They have a significant impact not only on the physical and mental health of those affected but also on their families and the communities they live in. At the same time, all communities have

their own traditional mechanisms for support and contain a range wide of resources that can be helpful in preventing mental health conditions from developing, promoting positive mental health and supporting the recovery of people that are struggling with a mental health condition.
In the wider context, people living with a mental health condition are often excluded from their communities and experience various violations to their basic human rights (discrimination, violence, exclusion from employment opportunities). The World Health Organization (WHO) estimates that the mean prevalence of global mental health disorders is 10.8% while the prevalence in emergency settings is 22.1% in any conflict-affected population.
During emergencies and crisis, the stigma, exclusion and discrimination towards people living with mental health conditions is often higher, which can cause isolation and protection issues. Communities can play a crucial role in promoting mental health as well as enhancing primary care and access. Their role is to help reduce mental health inequalities by providing community resources that connect people to community-based resources and by providing mental health education. This also helps to reduce the massive mental health treatment gap.

ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.
