What are potential effects of exposure to biohazards?

The potential effects of exposure to biohazards are extensive and can include a range of health consequences such as infection, disease transmission, or various adverse health effects. Biohazards typically involve biological substances that pose a threat to the health of living organisms, primarily humans. When an individual comes into contact with biohazards, they can be at risk of contracting infectious diseases caused by pathogens like bacteria, viruses, fungi, and parasites.

Infections can result from direct exposure or through vectors, leading to the transmission of diseases which might not be immediately visible. For instance, exposure to contaminated material can lead to infections such as hepatitis or HIV, among others. Additionally, adverse health effects can also encompass a wide variety of symptoms that differ in severity depending on the type of pathogen and the individual's health status.

The other choices focus on more limited aspects of potential biohazard effects. Skin irritation, allergic reactions, fever, and fatigue may occur as a result of exposure but do not encompass the full spectrum of risks associated with biohazards, which are fundamentally more serious and far-reaching. Therefore, understanding that biohazards can lead to infection and disease transmission highlights the importance of comprehensive training and safety protocols in hazardous environments.
