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).

These WHO interim recommendations on the use of the Pfizer – BioNTech BNT162b2 vaccine against Covid-19 were developed on the basis of advice issued by the Strategic Advisory Group of Experts on Immunization (SAGE) and the evidence summary included in the background document referenced below.

TNew data from the World Health Organization reveal that the COVID-19 pandemic has disrupted malaria services, leading to a marked increase in cases and deaths.
According to WHO’s latest World malaria report, there were an estimated 241 million malaria cases and 627 000 malaria deaths worldwide i...n 2020. This represents about 14 million more cases in 2020 compared to 2019, and 69 000 more deaths. Approximately two-thirds of these additional deaths (47 000) were linked to disruptions in the provision of malaria prevention, diagnosis and treatment during the pandemic.
As in past years, the report provides an up-to-date assessment of the burden of malaria at global, regional and country levels. It tracks investments in malaria programmes and research as well as progress across all intervention areas. This latest report draws on data from 87 countries and territories with ongoing malaria transmission.

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.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

The case for evidence- based communication of science
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.

Global Biodiversity Outlook (GBO) is the flagship publication of the Convention on Biological Diversity (CBD). It is a periodic report that summarizes the latest data on the status and trends of biodiversity and draws conclusions relevant to the further implementation of the Convention.
GBO-5 pro...vides global summary of progress towards the Aichi Biodiversity Targets and is based on a range of indicators, research studies and assessments (in particular the IPBES Global Assessment on Biodiversity and Ecosystem Services), as well as the national reports provided by countries on their implementation of the CBD. The national reports provide rich information about the steps taken in countries worldwide in support of biodiversity conservation, sustainable use, and the fair and equitable sharing of benefits. This body of Information provides a wealth of information on the successes and challenges in implementing the Strategic Plan for Biodiversity 2011-2020 and in reaching the Aichi Biodiversity Targets.
This Outlook draws on the lessons learned during the first two decades of this century to clarify the transitions needed if we are to realize the vision agreed by world governments for 2050, ‘Living in Harmony with Nature’.

Front. Med., 27 November 2020 | https://doi.org/10.3389/fmed.2020.594728. The Checklist included eight actions for implementing rural pathways in LMICs: establishing community needs; policies and partners; exploring existing workers and scope; selecting health workers; education and training; workin...g conditions for recruitment and retention; accreditation and recognition of workers; professional support/up-skilling and; monitoring and evaluation. For each action, a summary of LMICs-specific evidence and prompts was developed to stimulate reflection and learning. To support implementation, rural pathways exemplars from different WHO regions were also compiled. Field-testing showed the Checklist is fit for purpose to guide holistic planning and benchmarking of rural pathways, irrespective of LMICs, stakeholder, or health worker type.
