How does the Corona Virus (COVID-19) spread?

Human to human spread

COVID-19 is a new disease and experts are still researching how it is spread and transmitted, the severity of the disease it causes, and the extent of its spread throughout the world.

This virus is thought to spread primarily from human to human, namely:

• Between people who touch and are close to each other (within a distance of about 6 feet).

• Through the spark of respiration produced when an infected person coughs or sneezes.

This spark can land on the mouth or nose of people who are nearby or may be inhaled into the lungs.

Can someone spread the virus without signs and symptoms of illness?

People are considered to be in the most infectious condition when they have the most severe symptomatic symptoms.

Some spread can occur before people show symptoms, although there have been reports of how this spread, but this is not considered as the main way of spreading the virus.

Spread from contact with contaminated surfaces or objects

It is possible for a person to get infected with COVID-19 by touching a surface or a virus contaminated object on it and then touching their own mouth, nose or eyes, but this is also not considered a primary way of spreading the virus.

How easily does the virus spread?

How easily the virus spreads from human to human can vary. Some viruses are very contagious (spread easily) such as measles, while other viruses do not spread easily. Another factor is whether the spread is continuous and spread continuously without stopping.

The COVID-19 virus appears to spread easily and sustainably in communities in several geographic areas affected.
