В ответ на растущую пандемию COVID-19 и нехватку ресурсов и реагентов для молекулярного тестирования, многие производители диагностич...ских тестов разработали и начали продавать простые в использовании экспресс-системы, позволяющие выполнять тестирование вне лабораторий. Эти простые тестовые наборы основаны либо на обнаружении белков вируса COVID-19 в респираторных образцах (например, мокроте, мазке из зева), либо на обнаружении в крови или сыворотке человека антител, образующихся в ответ на инфекцию.

UNFPA aims to achieve three world-changing results by 2030, the deadline for achieving the Sustainable Development Goals. These are: Ending unmet need for family planning, ending gender-based violence including harmful practices such as female genital mutilation and child marriage, and ending all pr...eventable maternal deaths. COVID-19 pandemic could critically undermine progress made towards achieving these goals.

При инфицировании в естественных условиях выработка иммунитета к патогенному микроорганизму проходит в несколько этапов и заним...ет от 1 до 2 недель. При вирусной инфекции врожденный иммунитет обеспечивает немедленную реакцию организма, которая заключается в активации неспецифического иммунного ответа, приводящего к замедлению инфекционного процесса макрофагами, нейтрофилами и дендритными клетками, и которая в ряде случаев обусловливает бессимптомное течение инфекции. Затем происходит активация адаптивного иммунного ответа, при котором в организме начинается выработка специфических антител, способных к связыванию с вирусными частицами. Данные антитела являются белками и носят название иммуноглобулинов. Кроме того, в организме образуются Т-клетки, способные распознавать и уничтожать другие клетки, пораженные вирусом. Это звено иммунитета носит название клеточного. Функционирование нескольких звеньев иммунитета при адаптивном ответе может способствовать элиминации вируса из организма, а при достаточной активности реакции – препятствовать переходу заболевания в тяжелую форму и повторному заражению той же инфекцией. Количественной мерой данного процесса является уровень антител в крови.

Infection control instructions call for use of alcohol-based hand rub solutions to inactivate severe acute respiratory syndrome coronavirus 2. We determined the virucidal activity of World Health Organization–recommen...ded hand rub formulations, at full strength and multiple dilutions, and of the active ingredients. All disinfectants demonstrated efficient virus inactivation.

To contain the spread of COVID-19 and to keep infections at a manageable level, many countries have instituted lockdowns and social distancing. In India, a nationwide 21-day lockdown was announced with effect from 25 March 2020. This lockdown is expected to avert a sudden and large in...crease in the number of infections in the short term. Additionally, interventions such as social distancing and isolation of infected individuals over several months could reduce peak infections. Interventions such as frequent handwashing, reduced mass gatherings, contact tracing, and quarantines could slow transmission and reduce overall infections.

Presently, there is no evidence that the virus responsible for the current COVID-19 pandemic is carried by domestic food-producing animals, such as chickens, ducks, other poultry, pigs, cattle, camels, horses, sheep, goats, rabbits, guinea pigs or fish. While live animals can be a source of pathogen...s, all types of food can potentially be contaminated through contact with contaminated equipment, surfaces or environments. Proper cleaning and the prevention of cross-contamination are critical in the control of foodborne illnesses. The application of sound principles of environmental sanitation, personal hygiene and established food safety practices will reduce the likelihood that harmful pathogens will threaten the safety of the food supply, regardless of whether the food is sourced from intensive agriculture, small stakeholders or wildlife.

This brief provides key considerations for engaging communities on COVID-19 and tips for how to engage where there are movement restrictions and physical distancing measures in place, particularly in low-resource settings.
This guidance note developed by UNICEF explains how the WASH sector can implement infection prevention and control measures in households and community settings. It focuses on reducing the exposure to the disease in vulnerable community settings and public spaces, and the transmission of the disease... in home and community settings hosting patients and contacts. This brief is available in English, Spanish, and French here.

This document aims to help EU/EEA public health authorities in the tracing and management of persons, including healthcare workers, who had contact with COVID-19 cases. It outlines the key steps of contact tracing, including contact identification, listing and follow-up, in the context of the COVID-...19 response.

The following is a breakdown of key considerations to guide planning and resource allocation for COVID-19 preparedness and response to support UNHCR regional and country operations in Public Health, WASH, Shelter and Settlements programmes. While some of the activities are more relevant in camps or ...settlements it is important to assess the availability of all services outlined. These are based on the Strategic preparedness and Response Plan for COVID 19 and UNHCR guidance for operations and, where relevant, operation or site level outbreak preparedness and response plans.

This report provides an overview of the key information gaps and limitations in interpreting existing COVID-19 data
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.

Today, more children than ever before are displaced within their own countries. Their harrowing stories of displacement are unfolding every day, and with increasing frequency. At the end of 2019, approximately 45.7 million people were internally displaced by conflict and violence (Fig. 1.1). Nearly ...half – 19 million – were estimated to be children. And millions more are displaced every year by natural disasters.

Since March, the COVID-19 pandemic has impacted operations and required a different approach to communication with communities.
UNHCR communication channels have been rapidly enhanced and enlarged to ensure the continued provision of vital health and protection information.
Child friendly spaces (CFS) are safe spaces where
communities create nurturing environments in which
children can access free and structured play and
learning activities. CFS, also commonly referred to
as Child Centred Spaces or Safe Spaces for Children,
may provide educational and psychosocial... support
and other activities that restore a sense of normality
and continuity for children whose lives have been
disrupted by war, natural disaster or other emergency
situations.

The WHO Global Health Estimates show that nearly half a million deaths (493 471) occurred in the WHO European Region due to violence and injuries in 2016. This represents a decline of 29% from 2000. Injuries account for 5.3% of all deaths and 9.6 of all years of life lost. They are a leading cause o...f death in people aged 15–29 years and the second leading cause of death for young people aged 5–14. The three leading causes of injury deaths are self-directed violence (141 089), falls (83 325) and road-traffic injuries (78 198). Inequalities in injury deaths exist in the Region, with mortality rates 2.4 times higher in males than in females and 1.5 times higher in middle-income compared to high-income countries.
