Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

TB remains one of the world’s deadliest infectious diseases, second only to COVID-19, and drug-resistant TB strains are still a major concern. In the fight against TB, urgent investment is critical, especially in the context of the ongoing pandemic.

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).

This report presents country, regional and global estimates of low birth weight for 2000, together with a detailed description of the methods used in calculating the estimates. Some limited data on trends are also included. The limitations of low-birth-weight data are described and recommendations a...re made for further improvements in the data for this important indicator of health.

Eight years after Super Typhoon Haiyan, the most destructive storm to ever hit the Philippines, Super Typhoon Rai brought similar torrential rains, violent winds, mudslides, floods and storm surges to central parts of the Philippines, leaving a wide path of destruction and debris in its wake. While ...not as powerful as Haiyan in terms of wind strength, evidence shows that Rai damaged houses, infrastructure and livelihoods on a comparable scale or in even greater numbers. Most striking, Rai damaged 1.57 million homes, 500,000 more than Haiyan, across 11 of the Philippines 17 regions, with around 180,000-200,000 people still displaced – either still in evacuation centers or staying with friends, family or other temporary housing.

The COVID-19 pandemic has led to large increases in healthcare waste, straining under resourced healthcare facilities and exacerbating environmental impacts from solid waste. This report quantifies the additional COVID-19 healthcare waste generated, describes current healthcare waste management syst...ems and their deficiencies, and summarizes emerging best practices and solutions to reduce the impact of waste on human and environmental health. The recommendations included in the report build on actions in the WHO manifesto for a healthy recovery from COVID-19: prescriptions and actionables for a healthy and green recovery. They target the global, national and facility levels to promote a “win–win” scenario for COVID-19 PPE use, testing and vaccinations that are safe and support environmental sustainability.

Countries reported disruptions in all health-care settings. In more than half of countries surveyed, many people are still unable to access care at the primary care and community care levels. Significant disruptions have also been reported in emergency care, particularly concerning given the impact... on people with urgent health needs. Thirty-six per cent of countries reported disruptions to ambulance services; 32% to 24-hour emergency room services; and 23% to emergency surgeries.
Elective surgeries have also been disrupted in 59% of countries, which can have accumulating consequences on health and well-being as the pandemic continues. Disruptions to rehabilitative care and palliative care were also reported in around half of the countries surveyed.
Major barriers to health service recovery include pre-existing health systems issues which have been exacerbated by the pandemic as well as decreased demand for care.

COVID-19 Situation Update OPS/WHO Argentina: 10 February 2022
Situation report generated by the OPS/WHO representation in Argentina
scientific brief, 2 March 2022
9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

Mortality statistics are fundamental to public health decision making. Mortality varies by time and location, and its measurement is affected by well known biases that have been exacerbated during the COVID-19 pandemic. This paper aims to estimate excess mortality from ...the COVID-19 pandemic in 191 countries and territories, and 252 subnational units for selected countries, from Jan 1, 2020, to Dec 31, 2021.

Compared with other health areas, the mental health impacts of climate change have received less research attention. The literature on climate change and mental health is growing rapidly but is characterised by several limitations and research gaps. In a field where the need for designing evidence-b...ased adaptation strategies is urgent, and research gaps are vast, implementing a broad, all-encompassing research agenda will require some strategic focus.
