Quick Answer: What Are The 4 Types Of Disease Transmission?

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..

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 are the 6 modes of transmission?

Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)

What is the most effective way to prevent infection?

Simply put, yes. Hand washing is the single most effective way to prevent the spread of infections. You can spread certain “germs” (a general term for microbes like viruses and bacteria) casually by touching another person.

What causes infectious disease?

Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They’re normally harmless or even helpful. But under certain conditions, some organisms may cause disease.

What are the types of disease transmission?

There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person. Indirect contact transmission occurs when there is no direct human-to-human contact.

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.

What are the 4 major disease vectors?

Disease vectorsMalaria (protozoan): Anopheles species of mosquito.Lymphatic filariasis (nematode worm): Culex, Anopheles, Aedes species of mosquito.Dengue (virus): Aedes species of mosquito.Leishmaniasis (protozoan): mainly Phlebotomus species of sandfly.More items…

What is vehicle transmission of infection?

The term vehicle transmission refers to the transmission of pathogens through vehicles such as water, food, and air. Water contamination through poor sanitation methods leads to waterborne transmission of disease. Waterborne disease remains a serious problem in many regions throughout the world.

Which of the following is an example of vehicle transmission of disease?

Contaminated Drugs, Blood, Blood Products, or Medical Devices. 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 is the best way to break the chain of infection?

Break the chain by cleaning your hands frequently, staying up to date on your vaccines (including the flu shot), covering coughs and sneezes and staying home when sick, following the rules for standard and contact isolation, using personal protective equipment the right way, cleaning and disinfecting the environment, …
