Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion
...
, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustaina
...
ble Development Goals (UN/SDG) aims at ending the epidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

on to patients and health workers. It is grounded in infectious diseases, epidemiology, social science and health system strengthening. IPC occupies a unique position in the field of patient safety and quality universal health coverage since it is relevant to health workers and patients at every single health-care encounter. Poor WASH and IPC lead to health acquired infections, transmission of diseases from health facilities to communities and increased use of antibiotics and exacerbate outbreak and spread of infections- in this case- COVID- 19. On the contrary, effective IPC reduces hospital-acquired infections by at least 30% (WHO 2016).

Ce document d'orientation explique comment la distance physique (désignée dans les documents d'orientation précédents sous le nom de «distance sociale») peut aider à ralentir la transmission.
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 existing 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.

This is of concern due to an association between Zika virus infection and potential complications, including microcephaly and Guillain-Barré syndrome.
