Study Notes
Communicable Diseases
- A communicable disease is a disease that can be transmitted from one person to another through various modes of transmission.
Causes of Communicable Diseases
- Infectious agents such as bacteria, viruses, fungi, and parasites
- Poor hygiene and sanitation
- Inadequate immunization
- Contaminated food and water
- Insect vectors such as mosquitoes and ticks
Modes of Transmission for Communicable Diseases
- Direct contact: physical contact with an infected person or their bodily secretions
- Indirect contact: contact with contaminated objects or surfaces
- Airborne transmission: through the air when an infected person talks, coughs, or sneezes
- Vector-borne transmission: through the bite of an infected insect or tick
- Waterborne transmission: through contaminated water
- Foodborne transmission: through contaminated food
Direct Contact
- Direct contact involves physical contact with an infected person or their bodily secretions, such as:
- Touching
- Kissing
- Sharing needles
- Skin-to-skin contact
Air Contamination
- Air contamination occurs when an infected person talks, coughs, or sneezes, releasing droplets into the air that can be inhaled by others
- Airborne transmission can occur through:
- Inhaling droplets that contain infectious agents
- Touching contaminated surfaces and then touching one's face or mouth
