COVID-19 is transmitted through droplet or droplets of saliva. It usually occurs when a positive patient sneezes or coughs and is splashed with a liquid containing the virus. The spread of COVID-19 does not occur through airborne (air), but recent research has shown that a positive patient's saliva splash can stay in the air under several conditions.

On Thursday (9/7), the world health organization (WHO) officially acknowledged research evidence that shows transmission of the corona virus that causes COVID-19 can occur through the air.

This admission is a response to an open letter submitted by 239 scientists from 30 countries. The scientists urged WHO to review the research and revise recommended protocols for preventing transmission of COVID-19 in the community according to the new evidence.

Proof droplet COVID-19 patients can survive in the air and are contagious

Discussions about the potential for airborne transmission of COVID-19 have been going on for months. One piece of evidence published in the preprint journal medRxiv shows that COVID-19 can stay in the air for three hours in aerosol form. Viruses in the form of aerosols can be inhaled and make a person infected.

Aerosols are fine particles and can float in the air. An example of a liquid in the form of an aerosol is fog. It can stay in the air for hours and can be inhaled

Previously known, COVID-19 is transmitted through saliva or dropletwhich comes out when an infected person coughs, sneezes, or talks. Because the saliva splash is heavy, it can only be aired for a few seconds before falling to the surface due to the gravitational force. That's why one of the preventive protocols is to maintain a safe distance of about 2 meters.

However aerosols are a different physical state droplet. Viruses in the form of aerosols can stay in the air for a long time and have the potential to travel over long distances. For example, spread throughout the room.
