What Are The 5 Modes Of Transmission?

What are the methods of transmission?

Transmission can be by direct or indirect contact or through airborne transmission.

Direct contact is person-to-person transmission of pathogens through touching, biting, kissing, or sexual intercourse.

Microorganisms can also be expelled from the body by coughing, sneezing or talking..

What are the 8 different modes of transmission?

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

What are the four routes of transmission?

The main routes of transmission are listed below.Person-to-person. Touch. … Food. Microbes need nutrients for growth and they like to consume the same foods as humans. … Water. Some diseases are caused by drinking water that is contaminated by human or animal faeces, which may contain disease-causing microbes. … Insects. … Fomites.

What is the difference between a reservoir and a vector?

A disease reservoir is analogous to a water reservoir. But instead of supplying water, a disease reservoir serves as a supply for a virus or other pathogen. Vector: Any living creature that can pass an infection to another living creature.

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 5 basic modes of transmission of infection?

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 are the three main routes of transmission?

What disease can be transmitted through saliva?

Viruses responsible for diseases such as hepatitis viruses, herpesvirus infections (e.g., with Herpes simplex types 1 and 2, Epstein-Barr virus, Cytomegalovirus, and Kaposi syndrome herpesvirus), and papillomaviruses can be conveyed by kissing—as can potentially other viruses present in saliva such as Ebola and Zika …

What is the most common mode of transmission for infection?

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 4 ways infections 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?

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 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 are the modes of transmission of communicable diseases?

A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.
