Common sources of infection include contaminated food and water, person-to-person contact, sexual contact, contaminated objects, and airborne droplets from coughs and sneezes. In healthcare settings, healthcare-associated infections can also occur due to poor infection control practices.

Bacteria and viruses are the most common agents of infection. These are usually acquired by touching a contaminated surface or person. The best way to minimize risk of infection is to practice proper hand washing protocols.
