A healthcare worker has been exposed to potentially infectious bodily fluid
and exhibits the following symptoms: weight loss, low-grade fever, night
sweats, and vulnerability to pneumonia and intestinal disorders. What
bloodborne disease might this employee have?
Select the best option.

Hepatitis B
Hepatitis C
HIV

Answers

Answer:

According to the symptoms presented, the blood-borne disease that the employee exposed to potentially infectious bodily fluid could have is HIV.

Explanation:

HIV infection is a disease that can be transmitted by contact with blood or body fluids of a sick person, being a biological risk for health personnel.

Acquired immunodeficiency syndrome is the result of HIV infection.This virus produces a state of immunosuppression that leads to symptoms such as weight loss, low-grade fever, night sweats, increased susceptibility to infections such as pneumonia, and digestive disorders such as chronic diarrhea.

Depending on the symptoms, the employee may have acquired HIV infection.

The other options are not correct because:

    Acute hepatitis B or C virus infections cause abdominal pain, high fever and acute weight loss, but do not increase susceptibility to pneumonia or gastrointestinal disorders.

A healthcare worker who has been exposed to potentially infectious bodily fluid and exhibits the symptoms above described might have HIV.

Human immunodeficiency virus (HIV) is a virus that causes damages to the immune system, leading to a disease called acquired immunodeficiency syndrome (AIDS).

Some common symptoms of AIDS include fever, chills, night sweats, muscle aches, fatigue, etc.

HIV can be transmitted through blood or other fluids of the body, only when viral load is high.

It has been estimated that healthcare professionals who are exposed to potentially infectious HIV fluids may have a 0.23% risk of becoming infected.

In conclusion, a healthcare worker who has been exposed to potentially infectious bodily fluid and exhibits the symptoms above described might have HIV.
