What does the term 'biohazard' refer to in healthcare?

The term 'biohazard' specifically refers to any biological substance that poses a threat to human health. This includes materials that can carry infectious agents, such as blood, bodily fluids, tissue, and any other biological materials that could potentially transmit diseases. In a healthcare setting, biohazards are of significant concern because they can lead to infection and illness in patients and healthcare workers alike.

Identifying and handling biohazards appropriately is crucial for infection control and patient safety. The correct protocols and disposal methods are essential to minimize risk and ensure a safe environment in healthcare facilities. The other options do not accurately capture the scope of what constitutes a biohazard; they reference various materials or items associated with healthcare but do not encompass the specific risk associated with biological threats to health.
