Esta primeira versão de Medicamentos para prevenção da COVID-19: Orientação dinâmica da OMS aborda o uso de hidroxicloroquina para prevenção da COVID-19. Segue-se a publicação de uma análise sistemática e NMA que reuniu dados de seis estudos com 6.059 participantes que não tinham COVID-...19 e receberam hidroxicloroquina. Três estudos envolveram participantes que tiveram uma exposição conhecida a uma pessoa com infecção por SARS-CoV-2. Em resposta à divulgação dos dados de estudos, o GDG da OMS desenvolveu recomendações sobre a hidroxicloroquina, um agente anti-inflamatório que atua por meio do bloqueio dos receptores Toll-like, reduzindo a ativação das células dendríticas. É usada para tratar a artrite reumatoide e o lúpus eritematoso sistêmico. Tem um efeito antiviral contra muitos vírus in vitro, inclusive o SARS-CoV-2, mas não foi demonstrado um efeito antiviral clinicamente útil para nenhuma infecção viral.

The second edition of the joint WHO, WIPO and WTO
publication “Promoting Access to Medical Technologies
and Innovation: Intersections between public health,
intellectual property and trade” (the Trilateral Study),*
published in 2020, included a special insert mappi...ng the
challenges posed by the COVID-19 pandemic in relation
to the integrated health, trade and IP policy framework set
out in the study. The Trilateral Study and the special insert
were designed to serve as background reference for policy-
makers in the widest sense – lawmakers, government
officials, delegates to international organizations, non-
governmental organizations (NGOs) and researchers
who seek a comprehensive presentation of the full range
of issues, including institutions and legal concepts with
which they may be unfamiliar. It is also designed to serve
as a factual resource for the three organizations’ technical
cooperation activities.
This update revises the information contained in that
insert in the light of more recent developments as of
30 August 2021. Further updates will be made to reflect
subsequent developments.

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.

The number of COVID-19 cases is on the rise again, with South Africa nearing half of all confirmed cases in the WHO African Region. Threats of new variants loom and low vaccination coverage raises questions on the future of the response to COVID-19. Prevention remains the key strategy in most sub-Sa...haran countries. Five National Centres (NCs) from the African Health Observatory Platform on Health Systems and Policies (AHOP), based in Ethiopia, Kenya, Nigeria, Rwanda and Senegal, reflect on lessons to be learnt from their containment responses in the initial phases. They construct timelines to highlight the policies and challenges associated with introducing a range of public health containment measures and
discuss the extent to which these measures continue to be valuable given the ever-changing nature of the pandemic.

INTRODUCTION: The COVID-19 pandemic has disrupted health systems around the world. The objectives of this study are to estimate the overall effect of the pandemic on essential health service use and outcomes in Mexico, describe observed and predicted trends in services over 24 months, and to estimat...e the number of visits lost through December 2020.
METHODS: We used health information system data for January 2019 to December 2020 from the Mexican Institute of Social Security (IMSS), which provides health services for more than half of Mexico's population-65 million people. Our analysis includes nine indicators of service use and three outcome indicators for reproductive, maternal and child health and non-communicable disease services. We used an interrupted time series design and linear generalised estimating equation models to estimate the change in service use and outcomes from April to December 2020. Estimates were expressed using average marginal effects on the risk ratio scale.
RESULTS: The study found that across nine health services, an estimated 8.74 million patient visits were lost in Mexico. This included a decline of over two thirds for breast and cervical cancer screenings (79% and 68%, respectively), over half for sick child visits and female contraceptive services, approximately one-third for childhood vaccinations, diabetes, hypertension and antenatal care consultations, and a decline of 10% for deliveries performed at IMSS. In terms of patient outcomes, the proportion of patients with diabetes and hypertension with controlled conditions declined by 22% and 17%, respectively. Caesarean section rate did not change.
CONCLUSION: Significant disruptions in health services show that the pandemic has strained the resilience of the Mexican health system and calls for urgent efforts to resume essential services and plan for catching up on missed preventive care even as the COVID-19 crisis continues in Mexico.

INTRODUCTION: Health service use among the public can decline during outbreaks and had been predicted among low and middle-income countries during the COVID-19 pandemic. In March 2020, the government of the Democratic Republic of the Congo (DRC) started implementing public health measures across Kin...shasa, including strict lock-down measures in the Gombe health zone.
METHODS: Using monthly time series data from the DRC Health Management Information System (January 2018 to December 2020) and interrupted time series with mixed effects segmented Poisson regression models, we evaluated the impact of the pandemic on the use of essential health services (outpatient visits, maternal health, vaccinations, visits for common infectious diseases and non-communicable diseases) during the first wave of the pandemic in Kinshasa. Analyses were stratified by age, sex, health facility and lockdown policy (i.e, Gombe vs other health zones).
RESULTS: Health service use dropped rapidly following the start of the pandemic and ranged from 16% for visits for hypertension to 39% for visits for diabetes. However, reductions were highly concentrated in Gombe (81% decline in outpatient visits) relative to other health zones. When the lock-down was lifted, total visits and visits for infectious diseases and non-communicable diseases increased approximately twofold. Hospitals were more affected than health centres. Overall, the use of maternal health services and vaccinations was not significantly affected.
CONCLUSION: The COVID-19 pandemic resulted in important reductions in health service utilizsation in Kinshasa, particularly Gombe. Lifting of lock-down led to a rebound in the level of health service use but it remained lower than pre-pandemic levels.

As a lower-middle-income country (LMIC), South Africa (SA) bears
the burden of maternal and neonatal mortality similar to other sub-
Saharan African countries. According to the Saving Mothers Report
2017/19, there has been a progressive and sustained reduction
in institutional maternal mortality... (iMMR) in the past three triennia
(2010-2019), from 320 per 100,000 live births to 120 per 100,000 live
births.
According to the Rapid Mortality Survey, the country’s infant mortality
rate has declined from 29 deaths per 1000 live births in 2014 to 25
deaths per 1,000 live births in 2018. The institutional neonatal death
rate showed a slight decrease from 12,7 deaths per 1,000 live births in
2016 to the current level of 12 per 1,000 live births and has remained
static at this level for the past three years (saDHIS).
Working towards the Sustainable Development Goal (SDG) of reducing maternal mortality to below 70 per 100 000 live births and neonatal mortality to 12 deaths per 1000 live births, South Africa aims to reduce institutional maternal mortality, neonatal mortality and stillbirths by 50% by 2030.
This Maternal, Perinatal and Neonatal Health Policy provides a
framework for the delivery of quality, comprehensive, and integrated
MNH services and will guide the development and review of guidelines
and related MNH interventions, including strengthening of the service
delivery platform, governance, leadership and accountability for
the provision of quality MNH services, development of advocacy
messages, and guiding civil society priorities and community
initiatives. The policy will also guide the development and review of
academic curricula and the setting of research priorities.

Every year, nearly 250 million people move across borders temporarily or permanently for a job opportunity, studying, to flee a crisis back home, or for other reasons. Another 750 million move for similar reasons within the borders of their countries. With the understanding that human mobility affec...ts public health, and health affects human mobility and migrants, for decades, IOM has been providing critical health services to women, children and men on the move, while standing by governments for technical and operational support as needed. In 2019, in lower-income settings and in complex emergencies, along the world’s most perilous migration routes, in the aftermath of natural disasters or in response to disease outbreaks, IOM’s health teams have provided hundreds of thousands with primary health-care consultations, mental health and psychosocial support, sexual and reproductive health care, pre-migration health services, and much more.
This year, more than ever before, as the world reels from the socioeconomic impact of COVID-19, we have experienced that health is a cross-cutting component of overall human development and well-being.

Tuberculosis (TB) prevention is essential for reaching the End TB targets in the South-East Asia Region (SEAR) of World Health Organization (WHO)1. The targets of 80% reduction in TB incidence rate and 90% reduction in TB mortality by 2030 (compared to 2015 levels) can be achieved only with addition...al interventions aimed at preventing TB, according to epidemiological modelling studies commissioned by the WHO South-East Asia Regional Office (WHO SEARO). Optimal implementation of TB preventive treatment (TPT) is a critical intervention to accelerate reduction in TB burden in the SEA Region, which bears nearly 43% of the global TB burden. TPT by itself has the potential to reduce the overall annual TB incidence rates by 8.3% (95% CrI 6.5–10.8) relative to 2015.
