Infectious diseases are the diseases caused by various pathogenic microorganisms such as virus, bacteria, protozoan, fungi, and other parasites. These infectious diseases can be transmitted by animals, humans, insects or other agents.

What are the main routes that infection can enter the body?

Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.

What are the 5 methods of disease transmission?

The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.

Which is the most common route of transmission?

Contact is the most frequent mode of transmission of health care associated infections and can be divided into: direct and indirect. An example of contact transmitted microorganisms is Noroviruses which are responsible for many gastrointestinal infections.

What are the three major components of the cycle of transmission?

It is a process that begins when (1) an infectious agent or pathogen (2) leaves its reservoir, source, or host through (3) a portal of exit, (4) is conveyed by some mode of transmission, (5) enters the host through an appropriate portal of entry, and (6) infects a susceptible host.

What are the 4 types of disease 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.

What is method of transmission?

A method of transmission is the movement or the transmission of pathogens from a reservoir to a susceptible host. Once a pathogen has exited the reservoir, it needs a mode of transmission to the host through a portal of entry. Transmission can be by direct or indirect contact or through airborne transmission.

How do viruses enter the human body?

In humans, viruses that cause disease like cold and flu are spread through bodily fluids, like spit or snot. The virus is so small that it leaves our bodies in these fluids, and can even float through the air in droplets from a sneeze or cough. The virus can enter the body through the eyes, nose, or mouth.
