What are the different ways in which infectious diseases can spread?
How infectious diseases spread
- Through the air. Droplets containing small particles of a disease, such as measles, chickenpox and influenza (the flu), can be present in the air when an infected person coughs or sneezes.
- Through direct contact.
- Through contact with contaminated surfaces or objects.
- Contaminated food or water.
What is the most common means of transmission of infectious diseases?
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.
How is disease transmitted?
Infectious diseases are commonly transmitted through direct person-to-person contact. Transmission occurs when an infected person touches or exchanges body fluids with someone else. This can happen before an infected person is aware of the illness. Sexually transmitted diseases (STDs) can be transmitted this way.
What are the five means of transmission of infection?
Five routes of disease transmission. There are five main routes of disease transmission: aerosol, direct contact, fomite, oral and vector, Bickett-Weddle explained at the 2010 Western Veterinary Conference. Diseases can be spread to humans (zoonotic) by those same five routes.
