viral transmission

Viral transmission is the process by which viruses spread from one person to another. This can happen through various routes such as respiratory droplets when an infected person coughs or sneezes, contact with contaminated surfaces, or bodily fluids like blood or saliva. Once the virus enters a new host, it can infect cells and replicate, potentially causing illness. Preventative measures include good hygiene, wearing masks, and vaccination. Understanding these routes helps in reducing the spread and protecting public health.
