Epidemiology
Modes of Disease Transmission
Understanding how pathogens move from a reservoir to a susceptible host.
Direct vs Indirect
- Direct: Person-to-person contact, droplets, or sexual contact.
- Indirect: Fomites, contaminated water, or foodborne.
- Vector-borne: Transmission via insects like mosquitoes or ticks.
- Airborne: Droplet nuclei remaining in the air for extended periods.
Nursing Precautions
- Implement contact, droplet, or airborne precautions based on transmission route.
- Emphasize hand hygiene to interrupt indirect transmission.
- Ensure proper PPE usage to protect the host interface.
