How does outbreak happened?

Answer 1

Outbreaks typically occur when a pathogen, such as a virus or bacterium, spreads among a population, often due to factors like increased human interaction, environmental changes, or compromised immunity. Transmission can happen through various routes, including direct contact, contaminated food or water, or vectors like insects. Poor sanitation, crowded living conditions, and lack of vaccination can exacerbate the spread. Once the pathogen finds a conducive environment, it proliferates, leading to an outbreak.
