Covid Transmissions FAQ
The current evidence suggests that the Covid-19 virus spreads through direct, indirect (via contaminated surfaces) or close contact with infected people via mouth and nose secretions. These secretions include secretion droplets, saliva or respiratory secretions which are released from the mouth or nose when an infected person for example coughs, sneezes, speaks or sings.
People who are in close contact (within 1 meters, perhaps longer distance) with an infected person can catch Covid 19 when those virus infected droplets get into mouth, nose or eyes.

When people that are infected with the Covid-19 virus sneezes, coughs or touches objects and surfaces they might leave infected droplets on these surfaces. (e.g. tables, doorknobs, handrails). If other people touches these surfaces and then touches their eyes, noses or mouths before cleaning their hands they might become infected by the Covid-19 virus.

Several outbreaks of Covid-19 is reported from some closed settings such as restaurants, nightclubs, public transports, places of worship or places of work where people may be shouting, singing or talking. Aerosol transmission cannot be ruled out in these locations, particularly not in indoor locations which are crowded and inadequately ventilated and where infected people spend long periods of time with other people.
SOURCE
Certain medical procedures that are conducted on people infected by Covid-19 can produce very small droplets, aerosols. These aerosols may potentially be inhaled by others not wearing appropriate personal protective equipment protecting eyes, mouth and nose. Therefore it is essential that all health workers performing these medical procedures take appropriate airborne protection measures.

Based on the current information about the Covid-19 virus transmission primarily occurs from people when they already have symptoms but can occur just before they develop symptoms. Some people who are infected but never develop symptoms can also pass the Covid-19 virus but it is still not clear to what extent this occurs.

Where the potential risk to health and social care workers cannot be established prior to face-to-face assessment or delivery of care within 2 meters, the recommendation is for health and social care workers in any setting to have access to and where required wear aprons, FRSMs, eye protection and gloves.

In the largest study conducted so far in order to find out in what extent face masks as well as eye protection prevents the transmission of Covid-19 virus the findings showed that eye protection is associated with less infection.
