What is the life cycle of the common cold virus and how does it impact its transmission and spread among individuals?

The common cold virus typically enters the body through the nose or mouth. It then attaches to cells in the respiratory tract and starts replicating. This leads to symptoms like a runny nose and coughing. The virus can be spread through respiratory droplets when an infected person coughs or sneezes, or by touching contaminated surfaces. The virus can survive on surfaces for a few hours to a few days, increasing the chances of transmission. Overall, the life cycle of the common cold virus and its ability to spread easily among individuals contribute to its high transmission rate.
