This report is primarily intended for the community of policymakers and researchers concerned about the rising risks of domestic, regional, and global infectious disease epidemics, and the collective failure to take the coordinated actions required to reduce such risks. These risks include the expec...ted health, economic, and societal costs that are borne by countries, regions, and even all nations in the case of pandemics (which are worldwide epidemics). These risks also include the consequences of increasing antimicrobial resistance (AMR) and its spread within regions and globally. A necessary first step is to monitor whether a broad range of stakeholders are acting to prevent outbreaks from becoming epidemics, whether their capacities to respond to epidemics are robust, and whether preparedness to respond to pandemics and limit the resulting economic and health damage is improving. Analyzing the adequacy of these efforts is vitally important for the decisions of policymakers to invest in the public health and disaster-risk management capacities. Early and effective control of disease outbreaks prevents substantial health and economic costs whether or not the disease can spread globally and become a pandemic.

22 April 2022, This document provides updated interim recommendations on the use of masks by health workers providing care to patients with suspected or confirmed COVID-19. This update is prompted by new evidence around mask use and COVID-19 transmission, as well as the emergence of variants of conc...ern including Omicron. Masks continue to be a critical tool to prevent the spread of COVID-19. These interim guidelines supersede the recommendations provided in the WHO recommendations on mask use by health workers, in light of the Omicron variant of concern published on 22 December 2022.
WHO continually evaluates the emerging evidence and will review these interim recommendations within two months and issue new guidance as needed.

Health communication has proven to play a crucial role in addressing diseases such as dengue, Zika and chikungunya, for which there are no definitive or easily accessible vaccines. In this context, this discipline becomes a fundamental tool to promote the change behavior and promote preventive pract...ices that reduce the transmission of these diseases. By not having a definitive medical solution, accurate and timely information, effectively disseminated through educational campaigns, media and communication channels public health, can significantly influence individual and community actions to control the spread of these mosquito-borne viruses. The accumulated research around the threat of the aforementioned arboviral diseases brings together a series of recommendations around specific communication activities, such as disseminating timely and accurate information that integrates public health concerns and the needs of information of the population, especially vulnerable groups such as women of childbearing age, pregnant women and health workers.

Antimicrobial resistance (AMR) is an important public health concern shared by developed and developing countries. In developing countries the burden of infectious diseases is greater and exacerbated by limited access to, and availability and affordability of, antimicrobials required to treat infect...ions caused by AMR organisms. With drugs not listed on the essential drugs list (EDL), problems of increased morbidity, costs of extended hospitalisation and mortality are extremely serious. The problem of susceptibility to and spread of infections caused by multidrug-resistant (MDR) infectious agents is fuelled by factors such as limited access to clean water and sanitation to ensure personal hygiene, malnutrition, and the HIV/TB epidemic.

Arsenical monotherapies were previously very successful for treating human African trypanosomiasis (HAT).
Melarsoprol resistance emerged as early as the 1970s and was widespread by the late 1990s.
Melarsoprol resistance represents the only example of widespread drug resistance in HAT patients wher...e the genetic mechanism has been established.
The current goal of elimination of HAT as a public health problem by 2020 may be undermined by the emergence and spread of resistance to current or new drugs.
Insights into potential resistance mechanisms for current and new drugs will facilitate predictions of the likelihood of resistance and will also facilitate rational approaches to minimizing, monitoring, and tackling the future emergence of resistance.

Religion has continued to play an important role in the Nigerian public’s perception of the coronavirus disease and the willingness to take the newly developed vaccine. In an April 2020 NOI Poll Survey conducted to ascertain the public’s perception of the coronavirus pandemic and the Nigerian go...vernment’s initial response to the virus, 42% of respondents who stated that they were immune to coronavirus highlighted their belief in God as their reason, regardless of religious affiliation. Recent public opinion polls have also revealed that although Nigeria has surpassed over 100,000 coronavirus cases, more than a third of Nigerians who are aware of current scientific advances regarding the coronavirus vaccine are unwilling to take it whenever it is eventually made available nationwide. These respondents anchored their hopes on their faith, which for the Nigerian government could signal another public health risk in its efforts to curb the spread of the disease.

When a person is infested with scabies mites the first time, symptoms typically take 4-8 weeks to develop after being infested. However, an infested person can transmit scabies, even if they do not have symptoms. Scabies usually is passed by direct, prolonged skin-to-skin contact with an infested pe...rson. However, a person with crusted (Norwegian) scabies can spread the infestation by brief skin-to-skin contact or by exposure to bedding, clothing, or even furniture that he/she has used.

As climate change’s impacts continue to accrue, countries are persistently making wrong choices that are harming human health.
A desperate global thirst for fossil fuels is worsening climate change, leading to more extr...eme weather events that have hit every continent, led to thousands of deaths, and caused $250+ billion in damage in 2021.
• People 65+ and children <1 experienced 3.7 billion more heatwave days in 2021 than the annual average from 1986–2005.
• Heat-related deaths shot up 68% from 2000–2004 to 2017–2021.
• Climate change is abetting infectious disease transmission, warming coastal waters and leading to the spread of Vibrio bacteria like the one that causes cholera, and expanding the reach of the malaria parasite.

South Africa reported it fist case of COVID-19 on 5 March 2020. While the first cases were imported, local transmission has led to a rapid increase in the number of cases. As of 21 April 2020, more than 3,400 cases and 58 deaths had been confirmed. On 15 March, President Cyril Ramaphosa declared a n...ational state of disaster, and the government has since taken several measures to curb the spread of the virus, including closing borders, implementing strict social distancing measures and a 35-day nation-wide lockdown. These measures, along with the global economic shock caused by the pandemic, are expected to generate rising needs requiring an immediate and urgent response. Although South Africa is considered an upper-middle-income country, the amount of disparities—social, economic, and gender—make the country particularly vulnerable during this emergency.

There is a broad consensus nowadays that the Earth is warming up as a result of greenhouse gas emissions caused by anthropogenic activities. It is also clear that current trends in the fields of energy, development and population growth will lead to continuous and ever more dramatic climate change. ...This is bound to affect the fundamental prerequisites for maintaining good health: clean air and water, sufficient food and adequate housing. The planet will warm up gradually, but the consequences of the extreme weather conditions such as frequent
storms, floods, droughts and heat-waves will have sudden onset and acute repercussions. It is widely accepted that climate change will have an impact on the spread of infectious diseases in Europe, which is likely to bring about new public health risks in the majority of cases. Transmission of infectious diseases depends on a number of factors, including climate and environmental elements. Foodborne and waterborne diseases, for instance, are associated with high temperatures. Disease-transmitting vectors (e.g. mosquitoes, sandflies and ticks) are highly sensitive to climate conditions, including temperature and humidity; their geographical distribution will widen as climate conditions change, potentially allowing them to spread into regions where they are not currently able to live.
The primary purpose of this manual on climate change and infectious diseases is to raise the awareness and the level of knowledge of health workers at national, regional and local levels in the former Yugoslav Republic of Macedonia on the health risks associated with climate change and infectious diseases. This manual was devel-
oped as part of the WHO Regional Office for Europe project, Protecting health from climate change: a seven–country initiative, implemented with financial support from the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

MICROBIAL DRUG RESISTANCEVolume 24, Number 5, 2018ªMary Ann Liebert, Inc.DOI: 10.1089/mdr.2017.0383
Antibiotic resistance (ABR) is a worldwide publichealth concern, with serious health, economic, and so-cietal repercussions. Its emergence is attributed to the se-lective pressure exerted by antib...iotic use in the community, hospitals, veterinary health, agriculture, aquaculture, and the environment. Additionally aggravating the situation is the fact that very few new antibiotics have recently been produced by pharmaceutical companies. It is widely acknowledged that food animals are key reservoirs of antibiotic-resistant bacteria and that antibiotic usage in this population favors the emergence, selection, and spread of resistance among animals and humans, both through zoonoses (infectious diseases trans-mitted between animals and humans) and the food chain.

People-centered approaches that help communities maintain protective behaviours and follow guidelines set out by public health and government agencies are more important than ever. The evidence is clear, communities play a role in preventing and controlling epidemics and they are best able to take a...ction and slow or stop the spread of disease when properly engaged and empowered. This toolbox in 2 parts offers best practice approaches to community engagement with families. Promoting individual and joint responsibilities for the safety of the family, this toolbox aims to bring families and households together to manage shared risks and agree to safe behaviours critical for their safety and the safety of their community.

WHO and Psyon Games have joined forces to launch a new tower defense game called the Antidote COVID-19 to turn complex, scientific information into a fun learning experience. During the course of the game, players will learn about their immune system, pathogens, vaccines and how to protect themselve...s from COVID-19.
The game comes at a critical point of the pandemic where misinformation is hindering COVID-19 vaccine acceptance and adherence to other public health measures due to fear, mistrust and doubt. By putting players in the driver’s seat, the game urges everyone to play a role in fighting harmful misinformation online, and learning and sharing the facts from trusted sources of information.
The game starts just before the pandemic begins. The player is recruited to halt the spread of SARS-COV-2, the virus that causes COVID-19, by developing vaccines and helping the human immune system fight off the virus. Based on real events, this online adventure takes the player to the frontline of science, ultimately providing lifesaving information in the palms of their hands.
