Contaminated objects.

Food and drinking water.

Animal-to-person contact.

Animal reservoirs.

Insect bites (vector-borne disease)More items….

What are 3 ways in which diseases can be transmitted?

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.

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 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 the three types of transmission based precautions?

There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.

How many types of disease transmission modes are there?

Contact transmission is the most common form of transmitting diseases and virus. 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.

What are the 6 modes of transmission?

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

What are the 5 major types of infectious agents?

Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Some common pathogens in each group are listed in the column on the right. Infectious agents can grow in various body compartments, as shown schematically in Fig.

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 is a mode of infection?

The term modes of transmission refer to how an infectious agent, also called a pathogen, can be transferred from one person, object, or animal, to another. Viruses, bacteria, parasites, or fungi can spread infectious diseases.

What is contagious disease?

Contagious diseases (such as the flu, colds, or strep throat) spread from person to person in several ways. One way is through direct physical contact, like touching or kissing a person who has the infection. Another way is when an infectious microbe travels through the air after someone nearby sneezes or coughs.

What are the four 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 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 are the 3 major portals of entry for disease?

Portals of entry into the human body include:Inhalation (via the respiratory tract)Absorption (via mucous membranes such as the eyes)Ingestion (via the gastrointestinal tract)Inoculation (as the result of an inoculation injury)Introduction (via the insertion of medical devices)

What is an example of vehicle 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.
