Dracunculiasis (Guinea worm disease), caused by the parasite Dracunculus medinensis, is traditionally acquired by drinking water containing copepods (water fleas) infected with D. medinensis larvae, but in recent years also appears increasingly to be transmitted by eating fish or other aquatic anima...ls. The worm typically emerges through the skin on a lower limb of the host 1 year after infection, causing pain and disability.

Rabies is a disease of animals but too often the outcome is gauged in terms of human suffering and
death. Despite this, in areas of the world where rabies is endemic there is often a lack of communication between veterinary and medical professionals, to the extent that the disease continues to thri...ve and potential victims are not treated. The problem is partly
exacerbated by a lack of awareness and experience of the disease and of what to do when confronted by suspect cases. In these technologically advanced days, although it is possible to learn “all there is to know” about almost any subject, it is sometimes difficult to distil the essence.

he aetiology of asthma and allergic disease remains poorly understood, despite considerable research. The International Study of Asthma and Allergies in Childhood (ISAAC), was founded to maximize the value of epidemiological research into asthma and allergic disease, by establishing a standardized m...ethodology and facilitating international collaboration. Its specific aims are: 1) to describe the prevalence and severity of asthma, rhinitis and eczema in children living in different centres, and to make comparisons within and between countries; 2) to obtain baseline measures for assessment of future trends in the prevalence and severity of these diseases; and 3) to provide a framework for further aetiological research into genetic, lifestyle, environmental, and medical care factors affecting these diseases. The ISAAC design comprises three phases. Phase 1 uses core questionnaires designed to assess the prevalence and severity of asthma and allergic disease in defined populations. Phase 2 will investigate possible aetiological factors, particularly those suggested by the findings of Phase 1. Phase 3 will be a repetition of Phase 1 to assess trends in prevalence.

The introduction of vaccines for coronavirus disease 2019 (COVID-19) added another measure to the existing set of
recommended preventive measures (wearing a mask in public, keeping a distance from other people and regular handwashing). The roll-out of the vaccines, however, raised concerns that vac...cination may lead to lower adherence to the existing
preventive measures. The advice from the World Health Organization (WHO) was to continue these public health and
social measures after being vaccinated.1 However, evidence from other epidemics suggests that there is lower adherence to
preventive measures when some level of protection exists (for example, individuals who use human immunodeficiency virus

The Global Burden of Disease (GBD) study, a collaborative endeavour of the World
Health Organization (WHO), the World Bank and the Harvard School of Public Health,
drew the attention of the international health community to the burden of neurological
disorders and many other chronic conditions. T...his study found that the burden of neurological
disorders was seriously underestimated by traditional epidemiological and health
statistical methods that take into account only mortality rates but not disability rates. The
GBD study showed that over the years the global health impact of neurological disorders
had been underestimated.

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.

An outbreak of a disease called monkeypox is currently taking place in many countries that do not typically have cases. This can beconcerning, especially for people whose loved ones or community have been affected. Some cases have been identified through sexual health clinics in communities of gay, ...bisexual and other men who have sex with men. It is important to note that the risk of monkeypox is not limited to men who have sex with men. Anyone who has close contact with someone who is infectious is at risk. However, given that the virus is being identified in these communities, learning about monkeypox will help ensure that as few people as possible are affected and that the outbreak can be stopped.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

To help parents keep their children healthy and fit, WHO has developed the Child Nutrition and Physical Activity Guide. In addition to parents, the guide may prove to be a useful tool for other adults (such as grandparents or caregivers) working with primary school-aged children.
The Child Nutrit...ion and Physical Activity Guide is published only in the Russian language with support from the Ministry of Health of the Russian Federation for use in Russian-speaking countries. It addresses the urgent need in some countries to improve child nutrition, particularly in areas that face a double health burden characterized by coexistence of undernutrition and overweight, obesity or noncommunicable diseases. Many children in those countries never eat breakfast, and their diet consists of large quantities of sweets and sugar-sweetened beverages with almost no vegetables and fruit.
The WHO guide also offers ideas on how to stimulate children’s interest in physical activity, such as active play, exercise or sports. This is especially relevant for countries of the Commonwealth of Independent States (CIS), where, according to the latest findings, schoolchildren have a low participation in organized sports and exercise. On the other hand, a high proportion of schoolchildren walk to school every day. This could be a good starting point for CIS countries to make physical activity a daily habit that not only improves children’s physical health, but also promotes better mental health and well-being.
The guide aims to ensure that children obtain the knowledge and skills to make healthy food choices, critically evaluate their diet and integrate physical activity into daily life.
