SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

Since its launch, GLASS has expanded in scope and coverage and as of May 2021, 109 countries and territories worldwide have enrolled in GLASS. A key new component in GLASS is the inclusion of antimicrobial consumption (AMC) surveillance at the national level highlighted in this fourth G...LASS report.
The fourth GLASS report summarizes the 2019 data reported to WHO in 2020. It includes data on AMC surveillance from 15 countries and AMR data on 3 106 602 laboratory-confirmed infections reported by 24 803 surveillance sites in 70 countries, compared to the 507 923 infections and 729 surveillance sites reporting to the first data call in 2017.
The report also describes developments over the past years of GLASS and other AMR surveillance programmes led by WHO, including resistance to anti-human immunodeficiency virus and anti-tuberculosis medicines, antimalarial drug efficacy.

The emergence and transmission of zoonotic diseases are driven by complex interactions
between health, environmental, and socio-political systems. Human movement is considered
a significant and increasing factor in these processes, yet forced migration remains an
understudied area of zoonotic res...earch–due in part to the complexity of conducting interdisciplinary
research in these settings.

Provision of water and sanitation and good hygiene practices play an essential role in protecting human health during all disease outbreaks, including during Ebola Virus Disease (EVD) outbreaks. This question and answer document provides practical, evidence-based recommend...ations on minimum requirements and best practices for water, sanitation, hygiene (WASH). It was originally developed in 2014 during the West Africa Ebola Outbreak and has been updated in 2021 to reflect lessons learned and new operational research data. The key recommendations on WASH remain the same.

Mosquito-borne diseases are expanding their range, and re-emerging in areas where they had subsided for decades. The extent to which climate change influences the transmission suitability and population at risk of mosquito-borne diseases across different altitudes and population densities has not be...en investigated. The aim of this study was to quantify the extent to which climate change will influence the length of the transmission season and estimate the population at risk of mosquito-borne diseases in the future, given different population densities across an altitudinal gradient.

WHO recommends that pre-exposure prophylaxis (PrEP) be offered as an additional prevention choice for HIV-negative individuals at substantial risk of HIV infection as part of combination prevention approaches.
HIV drug resistance has been rarely reported among PrEP users who tested HIV positive i...n randomized controlled trials or open-label studies. However, PrEP-selected HIV drug resistance could potentially negatively impact the effectiveness of treatment options among PrEP users who acquire HIV, since there is a potential for overlapping resistance profiles between antiretroviral drugs used for both PrEP and first-line antiretroviral therapy.

In 2016, the risk of premature mortality1 from noncommunicable diseases (NCDs) in Ethiopia was 18.3%. The economic costs of NCDs are significant and are due principally to their impact on the non-health sector (reduced workforce and productivity). In this study, it is estimated that NCDs cost Ethiop...ia at least 31.3 billion birr (US$ 1.1 billion) per year, equivalent to 1.8% of the gross domestic product (GDP). Less than 15% of the costs are for health care.

Haiti faces a double burden of disease. Infectious diseases continue to be an issue, while non-communicable diseases have become a significant burden of disease. More attention must also be focused on the increase in worrying public health issues such as road... injuries, exposure to forces of nature and HIV/AIDS in specific age groups. To address the burden of disease, sustained actions are needed to promote better health in Haiti and countries with similar challenges.

Risk communication encompasses all the basics of health communication but differs in the need for speed and reliance on trust. At times of crisis, leaders are called on to provide a quick, sensitive and trustworthy response.
Centre Africain de contrôle et de prévention des maladies (CDC Afrique) protocole par la surveillance renforcée du syndrome respiratoire aigu sévère (SRAS) et du syndrome grippal pour COVID-19 en Afrique

Le nombre d’États membres de l’Union signalant des cas de COVID-19 est ...en augmentation et il est probable que la transmission communautaire en Afrique se produira. L’OMS a récemment modifié la définition de cas suspect de COVID-19 pour inclure des infections respiratoires aiguës sévères et conseille de tester tous les cas de syndrome respiratoire aigu sévère (SRAS).1 Cependant, de nombreux États membres n’ont pas encore commencé à mettre en œuvre ces changements, ils concentrent toujours leurs efforts
de surveillance sur les personnes ayant des antécédents de voyage vers une zone de transmission locale de COVID-19. Cela signifie que les patients présentant des symptômes similaires, mais sans aucun contact apparent, peuvent ne pas être enquêtés.

The role of environmental contamination in transmission of COVID-19 virus is currently not clear. This protocol has been designed to determine (viable) virus presence and persistence on fomites in various locations where a patient infected with COVID-19 is currently receiving care or being isolated,... and to understand how this may relate to COVID-19 transmission events in these settings. It is therefore important that it is done as part of a comprehensive outbreak investigation and that information obtained by environmental studies is combined with the results of epidemiological, laboratory and sequence data from COVID-19 patient investigations.

Risk of spill-over of EVD to Uganda has been categorised as very high. On 28 September 2018, WHO elevated the risk at the regional level which includes Uganda from ‘high’ to ‘very high’. Uganda has a very long and largely porous border with the DRC. High population movements across the borde...rs occur for various reason including for trade, social activities and services and asylum. There are cross-border markets in several border districts in Uganda and DRC that involve thousands of people crossing into and out of DRC and Uganda for trade purposes several days in a week.

In 2007, WHO warned that infectious diseases are emerging and re-emerging at a rate that has not been seen before. The potential for infectious diseases to spread rapidly results in high morbidity and mortality, causing a potential global public health treat of major concern.
Several factors are ...contributing to the (re)emergence of infectious diseases such as population growth, living in close contact with animals, frequent travelling, poverty, destructive ecological changes due to economic development and land use and climate change result in global warming.
Especially Africa is at a threat for (re)emerging infectious diseases due to the huge population growth (expected to reach 2.5 billion by 2050) with rapid urbanisation. Additionally, people across and beyond the continent are excessively mobile which is combined with a weak health system. Moreover, the risk of (re)emerging infectious disease is further heightened by three newly adopted continental initiatives: African Continental Free Trade Area, Free Movement of Persons and African Passport and Single African Air Transport Market.
