Which of the following is a typical sign of a fungal infection?

Fever is indeed a typical sign of a fungal infection. When the body is fighting off an infection, including fungal infections, it often raises its temperature as part of the immune response. This elevation in body temperature helps to create an environment that is less favorable for the fungi and encourages the body’s immune cells to work more efficiently. In the context of systemic fungal infections, such as candidemia or aspergillosis, fever is commonly noted as one of the hallmark symptoms indicative of an ongoing infection.

In contrast, the other options listed do not specifically point to a fungal infection. Rapid heartbeat can be associated with a variety of medical conditions, including but not limited to anxiety and cardiovascular issues. Generalized itching might be more closely related to skin reactions, allergies, or even other types of infections, but it is not a definitive indicator of a fungal infection. Indigestion is typically related to gastrointestinal issues and is not a common symptom of fungal infections. Thus, fever remains the most specific and relevant sign associated with fungal infections in the provided choices.
