Are bloodborne pathogens the only disease-producing microorganisms?

• A. True
• B. False
• C. Only viruses
• D. Only bacteria

Answer: (B)

Disease-causing microorganisms come in many forms and can spread by different routes, not just through blood. Bloodborne pathogens are the subset of microbes that can be transmitted via blood, such as certain viruses and bacteria, but many other pathogens cause disease through other pathways. For example, tuberculosis and influenza spread through the air, norovirus and Salmonella through contaminated food or surfaces, and malaria through a bite from an infected mosquito. Fungi and parasites can also cause infections by various routes. Because of these diverse transmission methods, bloodborne pathogens are not the only disease-producing microorganisms. This distinction matters in infection prevention, which requires precautions for multiple routes of transmission beyond blood exposure.
