The following protocol has been designed to investigate the extent of infection, as determined by seropositivity in the general population, in any country in which COVID-19 virus infection has been reported. Each country may need to tailor some aspects of this protocol to align with public health, l...aboratory and clinical systems, according to capacity, availability of resources and cultural appropriateness. However, using a standardized protocol such as this one below, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of COVID-19 virus infection severity and attack rates, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as COVID-19 virus

Addendum to meeting report: Regional consultation on HIV epidemiologic information in Latin America and the Caribbean
Nested case-control study of health workers exposed to confirmed COVID-19 patients.
Similar objectives to the cohort study but case-control studies may be cheaper and provide robust evidence to characterize and assess the risk factors for SARS-CoV-2 infection in health workers exposed to COVID-19 p...atients.
Health workers with confirmed COVID-19 will be recruited as cases and other health workers in the same health care setting without infection will be recruited as controls (incidence density sampling).
Secondary objectives are similar to the cohort study.

Interim Guidance October 2022. This addendum addresses some of the methodological aspects of VE evaluations that have been learned during the past year, as well as those that have become relevant in the current epidemiological setting of the COVID-19 pandemic. For some of the COVID-19 vaccine method...ology issues there are still insufficient data to make a recommendation, in which case different options for approaching VE evaluations are presented.

The toolkit aims to provide researchers with guidance for improving the quality of studies that use administrative data to better ascertain child maltreatment incidence, response and service delivery. However, these are complex studies to conduct, and the toolkit is not meant to be comprehensive. Re...searchers using the toolkit should be prepared to follow up on the recommended resources contained within and to consult with other professionals, such as statisticians, to further improve the research design and execution

This version of Field Trials of Health Interventions includes seven new chapters on conducting systematic literature reviews, trial
governance, preliminary studies and pilot testing, budgeting and accounting, intervention costing and economic analysis, and Phase IV studies. Before new interventions... are released into disease control programmes, it is essential that they are carefully evaluated in ‘field trials’. These may be complex and expensive undertakings, requiring the follow-up of hundreds, or thousands, of individuals, often for long periods. This manual was designed to provide guidance on the practical issues in great detail

he aetiology of asthma and allergic disease remains poorly understood, despite considerable research. The International Study of Asthma and Allergies in Childhood (ISAAC), was founded to maximize the value of epidemiological research into asthma and allergic disease, by establishing a standardized m...ethodology and facilitating international collaboration. Its specific aims are: 1) to describe the prevalence and severity of asthma, rhinitis and eczema in children living in different centres, and to make comparisons within and between countries; 2) to obtain baseline measures for assessment of future trends in the prevalence and severity of these diseases; and 3) to provide a framework for further aetiological research into genetic, lifestyle, environmental, and medical care factors affecting these diseases. The ISAAC design comprises three phases. Phase 1 uses core questionnaires designed to assess the prevalence and severity of asthma and allergic disease in defined populations. Phase 2 will investigate possible aetiological factors, particularly those suggested by the findings of Phase 1. Phase 3 will be a repetition of Phase 1 to assess trends in prevalence.

Traditionally, understanding of the psychiatric and psychological effects of trauma have been developed from studies with adults and then applied to trauma-exposed children with some modifications. While this is an important step to understanding the sequelae of trauma in children and adolescents, t...he adverse developmental effects of traumatic exposures on the rapidly evolving neurological, physical, social and psychological capacities of children calls for a developmentally sensitive framework for understanding, assessing and treating trauma-exposed children.

Many critical questions remain about the effectiveness of COVID-19 vaccines in real-world settings. These questions can only be answered in post-introduction vaccine effectiveness studies.This guidance document outlines an approach to leverage existing surveillance systems for Severe Acute Respirato...ry Infection (SARI) to estimate COVID-19 vaccine effectiveness (VE) in preventing SARI associated with laboratory-confirmed SARS-CoV-2 using existing SARI surveillance systems. The approach uses the test-negative design to evaluate VE; cases are SARI patients who tested positive for SARS-CoV-2, and controls are SARI patients who tested negative for SARS-CoV-2.

It is impossible to address the many complex needs of respiratory virus surveillance with a single surveillance system. Multiple systems, investigations and studies must each be fit-for-purpose to specific priority surveillance objectives, and only together can they provide essential information to ...policy-makers. In essence, each surveillance approach fit together as “tiles in a mosaic” that provides a complete picture of respiratory viruses and the impact of associated illnesses and interventions at the country level. This mosaic framework demonstrates how surveillance approaches may be implemented as coordinated and collaborative systems, well-matched to specific priority objectives.
