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 is a vehicle for indirect contact transmission?
Vehicles that may indirectly transmit an infectious agent include food, water, biologic products (blood), and fomites (inanimate objects such as handkerchiefs, bedding, or surgical scalpels). A vehicle may passively carry a pathogen — as food or water may carry hepatitis A virus.
Which of the following is an example of indirect contact transmission?
Indirect contact transmission involves transfer of microorganisms via an object. Examples include, hands not washed between residents, contaminated gloves, objects in the resident’s bed space or environment, medical equipment, and/or contaminated instruments. Indirect contact is also a common mode of transmission.
What is the most common vehicle for disease transmission?
Drugs, transfusions of blood or blood products (e.g., clotting factors for hemophiliacs), and medical devices are all considered “common vehicles,” and contamination of these medical products can cause small or large disease outbreaks.
What are the three types of transmission based precautions?
There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.
How can you become infected by direct or indirect contact?
Examples of direct contact are touching, kissing, sexual contact, contact with oral secretions, or contact with body lesions. Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air.
What are the 5 modes 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.
What are examples of direct and indirect contact quizlet?
What are examples of direct and indirect contact? Direct contact – touching an open wound on an infected person. Indirect contact – inhaling the air after an infected person has sneezed or handling soiled bed sheets from an infected patient.

Which source is a vehicle for infection transmission?
Common vehicle transmission: Common vehicle transmission refers to transmission through a contaminated source. Examples include food, medication, intravenous fluid, or equipment that transmits infection to multiple hosts. This transmission may result in a large-scale outbreak.
What is the most common means of transmission of infectious diseases?
Person to person. Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.
What are the 6 chains 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.
