This brief provides key considerations for engaging communities on COVID-19 and tips for how to engage where there are movement restrictions and physical distancing measures in place, particularly in low-resource settings.
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.

This updated implementation guidance is intended for all those who set policy for, or offer care to, pregnant women, families and infants: governments; national managers of maternal and child health programmes in general, and of breastfeeding- and BFHI-related programmes in particular; and health-f...acility managers at different levels (facility directors, medical directors, chiefs of maternity and neonatal wards). The document presents the first revision of the Ten Steps since 1989. The topic of each step is unchanged, but the wording of each one has been updated in line with the evidence-based guidelines and global public health policy.

During the year 2022, COVID-19 continued to be a significant challenge in Eritrea as in many other countries across the world. As COVID-19 devastated communities around the world, WHO worked with the MoH to strengthen the National and Sub-National health systems in order to meet community needs and ...mitigate the devastation during the pandemic and beyond.
One of the major achievements in the year 2022 was the beginning of the journey towards validation of
the elimination of mother to child transmission of HIV, syphilis, and hepatitis B. This is the culmination of years
of commitment and determination by the political leadership, national and international partnerships to
reduce the associated indices to levels that qualify for elimination.

Unpreparedness of health professionals to address non-communicable diseases (NCD) at peripheral health facilities is a critical health system challenge in Mozambique. To address this weakness and decentralize NCD care, training of the primary care workforce is needed. We describe our experience in t...he design and implementation of a cascade training of trainers (ToT) intervention to strengthen the prevention and control of cardiovascular disease.

The COVID-19 pandemic has had unprecedented public health, economic, and social impacts on the international community, and prompted an unprecedented range and size of policy actions globally. Collective efforts, at national, regional, and global levels, were called for to contain and mitigate such ...impacts. The public health response measures alone proved to be insufficient, calling for additional socio-economic policy interventions such as ring-fencing economic activities to contain the spread of the virus. Faced with devastating socio-economic costs, all possible sources of financing, both public and private, have been explored.

During fresh fruit and vegetables (FFV) production, water is used for a variety of purposes. Even the water was conventionally treated and disinfected, it may still potentially contain human pathogens, albeit at low concentrations. A risk assessment, appropriate to the national or local production c...ontext, should be conducted to assess the potential risks associated with a specific water source or supply in order to devise the appropriate risk mitigation strategies.
Since the 48th session of Codex Committee on Food Hygiene (CCFH) noted the importance of water safety and quality in food production and processing, FAO and WHO has undertaken the work on this subject. This report describes the output of the third in a series of meetings, which examined appropriate and fit-for-purpose microbiological criteria for water used with fresh fruit and vegetables. The advice herein will support decision making when applying the concept of fit-for-purpose water for use in the pre- and post-harvest production of fresh fruit and vegetables.

The WHO CIA List should be used as a reference to help formulate and prioritize risk assessment and risk management strategies for containing antimicrobial resistance. The WHO CIA List supports strategies to mitigate the human health risks associated with antimicrobial use in ...food-producing animals and has been used by both public and private sector organizations. The list helps regulators and stakeholders know which types of antimicrobials used in animals present potentially higher risks to human populations and how use of antimicrobials might be managed to minimize antimicrobial resistance of medical importance. The use of the WHO CIA List, in conjunction with the OIE list of antimicrobials of veterinary importance (1) and the WHO Model Lists of Essential Medicines (2) , will allow for prioritization of risk management strategies in the human sector, the food animal sector, inagriculture (crops) and horticulture, through a coordinated multisectoral One Health approach.
