Interim rapid response guidance, 10 June 2022.
It includes considerations for certain populations such as patients with mild disease with considerations for community care, patients with moderate to severe disease, sexually active persons, pregnant or breastfeeding women, children and young persons.... The guidance also addresses considerations for clinical management such as the use of therapeutics, nutritional support, mental health services, and post-infection follow-up.
The document provides guidance for clinicians, health facility managers, health workers and infection prevention and control practitioners including but not limited to those working in primary care clinics, sexual health clinics, emergency departments, infectious diseases clinics, genitourinary clinics, dermatology clinics, maternity services, paediatrics, obstetrics and gynaecology and acute care facilities that provide care for patients with suspected or confirmed monkeypox

Chikungunya virus (CHIKV) is currently one of the most relevant arboviruses to public health. It is a member of the Togaviridae family and alphavirus genus and causes an arthritogenic disease known as chikungunya fever (CHIKF). It is characterized by a multifaceted disease, which is distinguished fr...om other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

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
Mars 2020
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.

EID Journal , Volume 27, no.12 , Dec. 2021. Early Release
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections may be underestimated because of limited access to testing. We measured SARS-CoV-2 seroprevalence in South Africa every 2 months during July 2020–March 2021 in randoml...y selected household cohorts in 2 communities. We compared seroprevalence to reported laboratory-confirmed infections, hospitalizations, and deaths to calculate infection–case, infection–hospitalization, and infection–fatality ratios in 2 waves of infection. Post–second wave seroprevalence ranged from 18% in the rural community children <5 years of age, to 59% in urban community adults 35–59 years of age. The second wave saw a shift in age distribution of case-patients in the urban community (from persons 35–59 years of age to persons at the extremes of age), higher attack rates in the rural community, and a higher infection–fatality ratio in the urban community. Approximately 95% of SARS-CoV-2 infections were not reported to national surveillance.

Clinical care for severe acute respiratory infection: toolkit: COVID-19 adaptation
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.

Fact Sheet, May 2018.
Nipah virus (NiV) is a zoonotic virus (it is transmitted from animals to humans) and can also be transmitted through contaminated food or directly between people. In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory ...illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers

Background book on Management of the Child with a Serious Infection or Severe Malnutrition
Mothers and healthcare workers who support them have many questions and concerns about whether it is safe for mothers with confirmed or suspected COVID-19 to be close to and breastfeed their babies during the pandemic.
To address their questions, WHO has released a list of Frequently asked question...s: Breastfeeding and COVID-19. The FAQ complements the WHO interim guidance: Clinical management of severe acute respiratory infection when COVID-19 is suspected and draws upon other WHO recommendations on infant and young child feeding.
The FAQs aim to provide information to healthcare workers supporting mothers and families in maternity services and community settings, and communicate how the interim guidance should be implemented. Additionally, the FAQs provide information about the protective effects of breastfeeding and skin-to-skin contact, and the harmful effects of inappropriate use of infant formula milk.
