Transmissible viral infections

Transmissible viral infections are illnesses caused by viruses that can spread from one person to another. Viruses are tiny infectious agents that invade cells in the body, causing illness. They spread through various ways, such as respiratory droplets when someone coughs or sneezes, contact with infected blood or bodily fluids, or touching surfaces contaminated with the virus. Common examples include the flu, COVID-19, and HIV. Preventive measures include good hygiene, vaccination, and avoiding close contact with infected individuals. Understanding transmission helps in controlling outbreaks and protecting public health.
