What are the mode of transmission of communicable disease?

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.

What are the indirect modes of transmission of infectious disease?

Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air. If healthy people inhale the infectious droplets, or if the contaminated droplets land directly in their eyes, nose or mouth, they risk becoming ill.

What are the modes of direct transmission?

Modes of transmission

Direct contact occurs through skin-to-skin contact, kissing, and sexual intercourse. Direct contact also refers to contact with soil or vegetation harboring infectious organisms. Thus, infectious mononucleosis (“kissing disease”) and gonorrhea are spread from person to person by direct contact.

What is droplet transmission of infection?

Droplet transmission occurs when bacteria or viruses travel on relatively large respiratory droplets that people sneeze, cough, or exhale. They travel only short distances (usually less than 2 meters) before settling.

How are diseases transmitted?

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 is the most common mode of infection transmission in the healthcare environment?

Contact is the most frequent mode of transmission of health care associated infections and can be divided into: direct and indirect. An example of contact transmitted microorganisms is Noroviruses which are responsible for many gastrointestinal infections.

What are the sources of infection and their modes of transmission in a healthcare setting?

Among patients and health care personnel, microorganisms are spread to others through four common routes of transmission: contact (direct and indirect), respiratory droplets, airborne spread, and common vehicle.
