What is the primary route by which humans spread Ebola to other humans?

• A. Inhalation of aerosols from distant individuals
• B. Contact with blood or body fluids of sick people (broken skin/mucous membranes, or bodies of those who have died)
• C. Contaminated water only
• D. Casual contact with healthy people

Answer: (B)

The main idea is that Ebola spreads mainly through direct contact with infectious bodily fluids, not by casual or airborne means. When a person who is sick or has died from Ebola has their blood or other body fluids (such as saliva, vomit, feces, urine, sweat, or semen) touched or comes into contact with broken skin or mucous membranes (eyes, nose, mouth), the virus can enter the body. Surfaces or objects contaminated with these fluids, like clothing, bedding, or medical equipment, can also transmit the virus if someone handles them and then touches their face or has open skin contact. This is especially high risk during caregiving or handling bodies at death. In contrast, normal inhalation of aerosols from distant individuals is not the primary mode of transmission, contaminated water is not a typical route, and casual contact with healthy people generally does not spread the virus.
