What are the types of indirect contact?

Indirect contact

• Airborne transmission. Some infectious agents can travel long distances and remain suspended in the air for an extended period of time.
• Contaminated objects.
• Food and drinking water.
• Animal-to-person contact.
• Animal reservoirs.
• Insect bites (vector-borne disease)
• Environmental reservoirs.

What is a direct contact disease?

These are diseases caused by microorganisms that are spread by person-to-person contact or indirect contact with contaminated objects.

What are the 4 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.

What is an example of indirect contact transmission?

Indirect contact transmission occurs when there is no direct human-to-human contact. Contact occurs from a reservoir to contaminated surfaces or objects, or to vectors such as mosquitoes, flies, mites, fleas, ticks, rodents or dogs.

What are the 3 main ways infection can get into the body?

Pathogens can enter the body by coming into contact with broken skin, being breathed in or eaten, coming into contact with the eyes, nose and mouth or, for example when needles or catheters are inserted.

What are the 6 steps in the chain of infection?

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.

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.

Is cholera spread by direct contact?

The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water. The infection is not likely to spread directly from one person to another; therefore, casual contact with an infected person is not a risk factor for becoming ill.

What is the most common mode of transmission?

Contact transmission. The most common mode of transmission, contact transmission is divided into two subgroups: direct contact and indirect contact.

What is indirect contact mode of transmission?

Is airborne transmission direct or indirect?

With airborne transmission, direct contact is not needed to spread disease (as compared with respiratory droplet transmission). Infection may be transmitted over short distances by large droplets, and at longer distances by droplet nuclei generated by coughing and sneezing.
