According to a study in China, scientists observed an individual spread coronavirus in a closed environment up to 4.5 meters away. It was also observed that the virus lingered in the area for at least 30 minutes to infect more individuals.
There’s also the topic of if warmer temperatures will affect the virus. According to the article:
The length of time it lasts on the surface depends on factors such as temperature and the type of surface, for example at around 37C (98F), it can survive for two to three days on glass, fabric, metal, plastic or paper.
We all know China is not known for their honesty and integrity, but we must rely on the information available until we have studies available to us from more reputable countries and organizations.
Tl;dr – Coronavirus observed to spread further and linger longer than previously observed.
