How can infectious agents be transmitted?
Subsequently, one may also ask, what are four ways that infection can be spread?
Infectious diseases can spread in a variety of ways: through the air, from direct or indirect contact with another person, soiled objects, skin or mucous membrane, saliva, urine, blood and body secretions, through sexual contact, and through contaminated food and water.
Subsequently, question is, what are the 6 modes of transmission? The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting this chain at any link.
Keeping this in view, what are the 3 modes of transmission?
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. The portal of entry is the means by which the infectious microorganisms gains access into the new host. This can occur, for example, through ingestion, breathing, or skin puncture.
How are the germs that cause infections and contagious diseases spread?
Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. Some — but not all — infectious diseases spread directly from one person to another. Contagious diseases (such as the flu, colds, or strep throat) spread from person to person in several ways.
