THE SPREAD - TRANSMISSION

THE SPREAD THE SPREAD

HUMAN-TO-HUMAN TRANSMISSION

Direct or indirect contact with infected secretions such as saliva and respiratory secretions or their respiratory droplets. The virus primarily spreads through these fluid droplets. Infected droplets are expelled whenever a carrier sneezes, coughs, speaks, or even breathes.

The virus may also become airborne when aerosols are generated in some process. New findings show that the previous minimum droplet size of 5 micrometers for transmission is incorrect, and that the virus stays on smaller particles (classified as “aerosols” which are airborne).

Airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed; i.e., endotracheal intubation and bronchoscopy.

GLOBAL TRANSMISSION AND IMPACT

AIR TRAVEL

With its origin in the city of Wuhan in China’s Hubei Province, COVID-19 has spread all across the globe. Its diffusion has been wild and cases are increasing at an exponential rate. The Above: As the map illustrates, harsh reality is that no one is immune to the virus, potentially the spread of making it a threat to humanity, considering the search for a vaccine the disease is still undergoing.
