What is a common initial symptom of Tularemia?

The correct answer highlights that skin ulcers are a common initial symptom of Tularemia. This zoonotic disease, caused by the bacterium Francisella tularensis, often presents with a distinctive ulcer at the site of infection. Typically, if the disease is contracted through a skin abrasion or direct contact with an infected animal, a painful ulcer may develop at the entry point. It’s important to note that these skin ulcers can be quite characteristic, appearing as a sore with a raised, red border.

In Tularemia, other symptoms can manifest later or in different forms depending on the mode of transmission, but the appearance of skin ulcers is particularly noteworthy as it is a classic sign of the infection. Other common symptoms like high fever, headaches, and joint pain can also occur, but they may not be as uniquely indicative of Tularemia as the skin ulcer is. Thus, recognizing skin ulcers as an initial symptom is essential for early diagnosis and treatment.
