What is often the first symptom that appears when an employee is infected with hepatitis B?

Jaundice, which is characterized by a yellowing of the skin and eyes, is commonly associated with liver conditions, including hepatitis B. This symptom can manifest later in the course of the infection, often indicating that the liver is severely affected.

Hepatitis B infection typically has an incubation period of about 30 to 180 days, and during this time, the virus multiplies in the body without producing significant symptoms. As the infection progresses, symptoms may become more apparent. Jaundice is the result of high levels of bilirubin in the bloodstream, a byproduct of the liver processing waste material, and signifies liver impairment. In cases of hepatitis B, jaundice usually appears as the disease progresses, making it a notable and often identifiable symptom.

While fatigue and nausea can occur in the early stages of hepatitis B, jaundice is more distinctive and is prominently linked with liver damage, making it a key indicator in the context of this question.
