The number of African Union Member States reporting COVID-
19 cases is increasing and there is a likelihood of community transmission. The WHO recently modified the COVID-19 suspect case definition to include severe acute respiratory infection and advises testing of all severe acute res...piratory illness (SARI) cases.1 However, many Member States have not yet started implementing these changes, they are still focussing surveillance efforts on individuals with travel history to an area with local COVID-19 transmission. This means patients with similar symptoms, but no apparent contact, may not
be investigated.

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.

Scientific brief
8 April 2020
Social distancing is an action taken to minimise contact with other individuals; social distancing measures comprise one category of non-pharmaceutical countermeasures (NPCs)1 aimed at reducing disease transmission and thereby also reducing pressure on health services.
This document builds upon exi...sting ECDC documents, including guidelines for the use of non-pharmaceutical measures to delay and mitigate the impact of 2019-nCoV, a rapid risk assessment: outbreak of novel coronavirus disease – 5th update, a technical report on the use of evidence in decision-making during public health emergencies, and a guidance document on community engagement for public health events caused by communicable disease threats in the EU/EEA.

Glaucoma, a disease that gradually affects the optic nerve, is the second leading cause of vision loss globally, and it continues to pose a challenge to the eye health professionals.
This joint ECDC-European Union Aviation Safety Agency (EASA) document aims to support Member States in determining a coordinated approach to reduce the risks related to the movement of people by air within and between the EU/EEA countries and the UK in the context of the COVID-19 pandemic, noting th...at the impact of quarantine and testing is likely to vary according to levels of ongoing community transmission, and in the context of ECDC’s current advice that non-essential travel should be avoided during the end-of year festive period

A “catastrophic” combination of drought and communities’ declining resilience has left an estimated 2.3 million people facing severe acute food insecurity – up from an estimate of 1.7 million people a month ago.
Communities across southern Africa have been affected by drought since late 2...018.
This year, large parts of southern and western Zambia received their lowest seasonal rainfall totals since at least 1981, the base year from which normal rainfall is benchmarked. At the same time, northern and eastern parts of the country were affected by flash floods and waterlogging, resulting in poor harvests.
