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.

This bi-weekly brief details the latest developments in scientific knowledge and public health policy from around the world as well as updates to the COVID-19-related guidance from Africa CDC, WHO and other public health agencies.
Brazilian media and science communicators must understand the main characteristics of misinformation in social media about COVID-19, so that they can develop attractive, up-to-date and evidence-based content that helps to increase health literacy and counteract the spread of false information.
Uso de doxiciclina para prevenção e tratamento de pacientes com Covid-19

The overall threat posed by Omicron largely depends on four key questions: (i) how transmissible the variant is; (ii) how well vaccines and prior infection protect against infection, transmission, clinical disease and death; (iii) how virulent the variant is compared to other varian...ts; and (iv) how populations understand these dynamics, perceive risk and follow control measures, including public health and social measures (PHSM).

The COVID-19 pandemic arrived in an evolving epidemiological context where some countries are experiencing a progressive decrease in HIV positivity in their testing programme as they are moving closer to the first 95 target. Distinguishing changes in HIV testing services due to the COVID-19 pandemic... from those resulting from evolving HIV testing strategies is crucial for adapting services and helping countries define their strategic mix of testing options moving forward. There is a need to focus, prioritize and plan for strategic efforts to prevent going further off the track toward achieving global targets and goals.
To support these efforts, WHO in partnership with ministries of health conducted an in-depth analysis of HIV testing services and antiretroviral therapy (ART) initiation prior to and during reported COVID-19 disruptions. Additional publicly available Global Fund and PEPFAR data was also reviewed and analysed. This analysis, and coordination with ministries of health, identified key service delivery adaptations utilized during COVID-19-related disruptions and formed the basis of this strategic guide.
This document focuses on current country needs, as well as plans for prioritization and potential surge support needs in the event of future disruptions. Although the data and implications are specific to sub-Saharan Africa, key principles and lessons can be applied elsewhere.

To assess the impact of the COVID-19 pandemic on health and HIV expenditure, UNAIDS carried out a modelling study on fiscal space for health and HIV. From a sample of 28 countries, three countries—the Democratic Republic of the Congo, Jamaica, and Lesotho—were selected to capture health and HIV ...expenditure impacts across countries with especially marked differences in burdens of disease (including HIV prevalence), HIV donor dependency, level of economic development, and geographic location. While the three-country sample is too small to permit findings to be generalized to other countries, these analyses are useful for informing UNAIDS’ work to identify some policy positions to minimize the COVID-19 pandemic’s impact on the HIV response.

The report identifies major global gaps in WASH services: one third of health care facilities do not have what is needed to clean hands where care is provided; one in four facilities have no water services, and 10% have no sanitation services. This means that 1.8 billion people use facilities that l...ack basic water services and 800 million use facilities with no toilets. Across the world’s 47 least-developed countries, the problem is even greater: half of health care facilities lack basic water services. Furthermore, the extent of the problem remains hidden because major gaps in data persist, especially on environmental cleaning.
This report also describes the global and national responses to the 2019 World Health Assembly resolution on WASH in health care facilities. More than 70% of countries have conducted related situation analyses, 86% have updated and are implementing standards and 60% are working to incrementally improve infrastructure and operation and maintenance of WASH services. Case studies from 30 countries demonstrate that progress is being propelled by strong national leadership and coordination, use of data to direct resources and action, and the mutual benefits of empowering health workers and communities to develop solutions together.

Adolescent girls and young women (AGYW) remain disproportionately affected by HIV in Eastern and Southern Africa (ESA), with 26 per cent of new infections attributed to this population. AGYW face many personal, social and structural barriers to access, uptake and use of traditional HIV prevention me...thods. Oral Pre-exposure Prophylaxis (PrEP) is proven to be highly effective as an additional prevention choice for reducing the risk of HIV acquisition, including for AGYW. Successful uptake and adherence to PrEP is critical in its effectiveness as an HIV prevention method, however, the current demand for PrEP by AGYW is low with suboptimal adherence.
Within the ESA region, there is currently great impetus to address these challenges and scale up PrEP for AGYW. A critical aspect of this is to leverage the learnings and evidence from implementation of how to improve the demand and quality of PrEP programming for this population. Improving the Quality of Pre-Exposure Prophylaxis Implementation for Adolescent Girls and Young Women in Eastern and Southern Africa examines the current efforts in the region to accelerate and scale up evidence-based PrEP delivery platforms. The implementation brief provides current knowledge and builds on WHO guidance to provide key considerations for implementation, including driving demand and improving quality, as well as focus on wider combination prevention and integration agendas.

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition...al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.
