A viral outbreak occurs when a virus spreads rapidly among a population, leading to an increase in infections. This can happen through direct contact, respiratory droplets, or contaminated surfaces. Common examples of viruses that cause outbreaks include influenza, COVID-19, and norovirus. During an outbreak, public health measures are often implemented to control the spread, such as vaccination, quarantine, and promoting hygiene practices. Health organizations monitor the situation to provide guidance and support to affected communities, aiming to reduce transmission and protect public health.
