Which disease primarily spreads through blood or bodily fluids?

The disease that primarily spreads through blood or bodily fluids is HIV (Human Immunodeficiency Virus). HIV is transmitted through direct contact with infected bodily fluids such as blood, semen, vaginal fluids, and breast milk. This makes it distinct from the other diseases listed.

Influenza, for example, is primarily spread through respiratory droplets when an infected person coughs, sneezes, or talks, rather than through blood or bodily fluids. Chickenpox is another viral infection that spreads through respiratory droplets as well as direct contact with the rash, and its transmission does not involve blood. Tuberculosis is an airborne disease that spreads through the inhalation of droplets from coughs or sneezes of an infected person, rather than through blood or bodily fluids.

Recognizing these modes of transmission is crucial in understanding how to prevent the spread of infectious diseases, especially in clinical and esthetic environments where exposure to bodily fluids may occur.
