COVID-19 has heavily emphasized how contact tracing is crucial for managing outbreaks, and as part of the strategy for adjusting, and eventually lifting, lockdowns and other stringent public health and social measures. As the pandemic develops further, it will be a core measure to manage further wav...es of infection. In early June 2020, the World Health Organization (WHO) convened an online global consultation on contact tracing in the context of COVID-19, looking at the lessons of the pandemic to date; known and emerging best practices; and the measures necessary for urgent implementation, scale-up, maintenance and enhancement of contact tracing activities.

Esta tercera versión resumida de la Guía para el cuidado de pacientes adultos críticos con COVID-19 en las Américas se elaboró con el objetivo de facilitar la consulta de las recomendaciones para el manejo de pacientes adultos críticos con COVID-19 atendidos en las unidades de cuidados intensi...vos. Ofrece recomendaciones basadas en evidencia para la identificación de marcadores y factores de riesgo de mortalidad de los pacientes críticos, el control de la infección, la recogida de muestras, la asistencia a los pacientes (ventilatoria y hemodinámica), el tratamiento farmacológico, la rehabilitación temprana, el uso de imágenes diagnósticas, la prevención de complicaciones y los criterios de egreso. Las recomendaciones están dirigidas a todo el personal de salud que atiende a pacientes en los servicios de urgencias y de emergencias y las unidades de cuidados intensivos. Asimismo, tienen por objetivo brindar apoyo a los responsables de la toma de decisiones y miembros de entidades gubernamentales relacionados con el manejo de pacientes con COVID-19 en las unidades de cuidados intensivos de la Región de las Américas

Le nombre de cas de COVID-19 augmente à nouveau, l’Afrique du Sud comptant pour près de la moitié de tous les cas confirmés de la Région africaine de l’OMS. La menace de nouveaux variants plane, et la faible couverture vaccinale soulève des questions concernant les mesures qui devront êtr...e prises pour lutter contre la COVID-19. Dans la plupart des pays d’Afrique subsaharienne, la prévention reste la stratégie clé. Dans ce document, cinq centres nationaux de la plateforme de l’Observatoire africain de la santé sur les systèmes et politiques de santé (AHOP), basés en Éthiopie, au Kenya, au Nigéria, au Rwanda et au Sénégal analysent les leçons à tirer de leurs mesures d’endiguement respectives lors despremières phases de la pandémie.

Increasing human demand for water and changes in water availability due to climate change threatens water security worldwide. Additionally, exploitation of water resources induces stress on freshwater environments, leadi...ng to biodiversity loss and reduced ecosystem services. We aimed to conduct a spatially detailed assessment of global human water stress for low to high environmental flow (EF) protection.

Human use of land has been transforming Earth's ecology for millennia. From hunting and foraging to burning the land to farming to industrial agriculture, increasingly intensive human use of land has reshaped global patterns of biodiversity, ecosystems, landscapes, and climate. This review examines ...recent evidence from archaeology, paleoecology, environmental history, and model-based reconstructions that reveal a planet largely transformed by land use over more than 10,000 years. Although land use has always sustained human societies, its ecological consequences are diverse and sometimes opposing, both degrading and enriching soils, shrinking wild habitats and shaping novel ones, causing extinctions of some species while propagating and domesticating others, and both emitting and absorbing the greenhouse gases that cause global climate change. By transforming Earth's ecology, land use has literally paved the way for the Anthropocene.

Following flood levels of the hydrological stations monitored in Niamey (Niger Republic) and Malan Ville (Benin Republic) reaching the red alert zone, torrential rainfall and ensuing floods affected 91,254 people or 15,209 households in Jigawa, Kebbi, Kwara, Sokoto, and Zamfara state (amongst other ...states) of Nigeria on 6 October 2020. The flood incident was caused by the intensity of the rainfalls at the peak of the flood season and the release of dams located in neighbouring Niger, Cameroon, and Benin, which resulted in the Benue and Niger rivers overflowing and affecting communities living along their banks and in surrounding areas.

This study aimed to analyze the geographical distribution of coronavirus disease 2019 (COVID-19) and to identify high-risk areas in space and time for the occurrence of cases and deaths in the indigenous population of Brazil. This is an ecological study carried out between 24 March and 26 October 20...20 whose units of analysis were the Special Indigenous Sanitary Districts. The Getis-Ord General G and Getis-Ord Gi* techniques were used to verify the spatial association of the phenomena and a retrospective space–time scan was performed. There were 32 041 confirmed cases of COVID-19 and 471 deaths. The non-randomness of cases (z score = 5.40; P < 0.001) and deaths (z score = 3.83; P < 0.001) were confirmed. Hotspots were identified for cases and deaths in the north and midwest regions of Brazil. Sixteen high-risk space–time clusters were identified for the occurrence of cases with a higher RR = 21.23 (P < 0.001) and four risk clusters for deaths with a higher RR = 80.33 (P < 0.001). These clusters were identified from 22 May and were active until 10 October 2020. The results indicate critical areas in the indigenous territories of Brazil and contribute to better directing the actions of control of COVID-19 in this population.

Community health worker teams are potential game-changers in ensuring access to care in vulnerable communities. Who are they? What do they actually do? Can they help South Africa realize universal health coverage? As the proactive arm of the health services, community health workers teams provide ho...usehold and community education, early screening, tracing and referrals for a range of health and social services. There is little local or global evidence on the household services provided by such teams, beyond specific disease-oriented activities such as for HIV and TB. This paper seeks to address this gap.

Transmission of many infectious diseases depends on interactions between humans, animals, and the environment. Incorporating these complex processes in transmission dynamic models can help inform policy and disease control int...erventions. We identified 20 diseases involving environmentally persistent pathogens (ie, pathogens that survive for more than 48 h in the environment and can cause subsequent human infections), of which indirect transmission can occur from animals to humans via the environment.

Wet markets have been implicated in multiple zoonotic outbreaks, including COVID-19. They are also a conduit for legal and illegal trade in wildlife, which threatens thousands of species. Yet wet markets supply food to millions of people around the world, and differ drastically in their physical com...position, the goods they sell, and the subsequent risks they pose. As such, policy makers need to know how to target their actions to efficiently safeguard human health and biodiversity without depriving people of ready access to food.
