Verified step by step guidance

1. Understand the definition of bloodborne pathogens: these are microorganisms such as viruses, bacteria, or parasites that are present in human blood and can cause disease.
2. Recognize that bloodborne pathogens are not limited to viruses; they can include bacteria and parasites as well, so the statement that they are exclusively viruses is false.
3. Know that bloodborne pathogens are transmitted through contact with infected blood or other potentially infectious materials, not through airborne droplets.
4. Evaluate each option by comparing it to the correct definition and transmission routes of bloodborne pathogens.
5. Conclude that the true statement is: 'They are microorganisms that can be transmitted through contact with infected blood.'
