Blood-Borne Diseases Quiz

Vector-borne diseases are transmitted by insects or other vectors, while blood-borne diseases are spread through contamination by blood and other body fluids. Examples of vector-borne diseases include West Nile virus, zika fever, and malaria, while examples of blood-borne diseases include HIV, hepatitis B, and hepatitis C.

Blood-borne diseases pose a significant risk due to the potential contamination of blood and other body fluids with various pathogens, including microorganisms like bacteria and parasites, as well as viruses such as HIV, hepatitis B, and hepatitis C. This poses a risk to health workers through occupational exposure and to the general population through various means of transmission, such as high-risk sexual behavior or intravenous drug use.

Blood-borne diseases can also be contracted through high-risk sexual behavior or intravenous drug use. Examples of high-risk sexual behavior include unprotected sexual intercourse with an infected person, while examples of intravenous drug use include sharing contaminated needles.
