The virus is generally a non-living cell when it is outside the body, living when it enters the body and uses the body resources to survive.
You may have seen spikes coming out of virus cell-like antennas. They are glycoproteins that help the virus to stick to our healthy cells.
The latest virus you have heard is Novel Corona Virus, referred to as COVID-19 by WHO.
It is derived from the Greek word Corona which means crown. Highly Contagious, which means it spreads quickly.
So, stay at home, stay safe, and ensure cleanliness.
