What infections can be passed through blood?
Bloodborne pathogens are microorganisms such as viruses or bacteria that are carried in blood and can cause disease in people. There are many different bloodborne pathogens, including malaria, syphilis, and brucellosis, and most notably Hepatitis B (HBV), Hepatitis C (HCV) and the Human Immunodeficiency Virus (HIV).
What are the 4 routes of infection?
Diseases can spread in many ways
- Airborne transmission. Airborne transmission occurs when infectious agents are carried by dust suspended in the air.
- Respiratory (droplet) transmission.
- Sexually transmitted diseases (STDs)
- Animal or insect transmission.
- Food or water transmission.
- Health care transmission.
Which of the following parasite can be found in peripheral blood film?

What are the 6 chains of infection?
The six links in the chain are:
- The Infectious Agent – or the microorganism which has the ability to cause disease.
- The Reservoir or source of infection where the microorganism can live and thrive.
- The Portal of Exit from the reservoir.
- The Mode of Transmission.
- The Portal of Entry.
- The Susceptible Host.
