Name one disease commonly transmitted through bodily fluids.

Hepatitis B is a viral infection that affects the liver and is indeed commonly transmitted through bodily fluids, including blood, semen, and vaginal secretions. It is a significant public health concern due to its high potential for transmission in various settings, including healthcare environments and through sexual contact. The virus can survive outside the body for at least seven days, making it a strong candidate for transmission even through small amounts of contaminated fluid. Other infections that share this mode of transmission include HIV and hepatitis C.

In contrast, diabetes mellitus, cardiovascular disease, and hypertension are not primarily transmitted through bodily fluids but are instead related to genetic, lifestyle, and environmental factors. Diabetes, for instance, is typically associated with metabolic issues that stem from insulin resistance or inadequate insulin production. Cardiovascular disease and hypertension are largely influenced by diet, exercise, and other risk factors rather than infectious agents. Thus, Hepatitis B stands out as the appropriate choice when considering diseases associated with fluid transmission.
