All of the following statement are true regarding Q fever except-
**Core Concept**
Q fever is a zoonotic disease caused by the bacterium *Coxiella burnetii*. It is primarily transmitted to humans through inhalation of aerosolized particles contaminated with the bacteria, often from infected animals such as cattle, sheep, and goats.
**Why the Correct Answer is Right**
The correct answer will be the statement that does not accurately describe Q fever. Q fever is characterized by its ability to form spores, which are highly resistant to environmental stressors and can remain viable for long periods. This property of *Coxiella burnetii* allows it to persist in the environment and be transmitted to humans through various routes.
**Why Each Wrong Option is Incorrect**
**Option A:** This statement is incorrect because Q fever is not typically associated with a rash. While some patients may exhibit a rash, it is not a characteristic feature of the disease.
**Option B:** This statement is incorrect because Q fever is not transmitted through the bites of infected ticks. While ticks can harbor *Coxiella burnetii*, they are not the primary vector for transmitting the disease to humans.
**Option C:** This statement is incorrect because Q fever is not typically associated with a fever above 103Β°F (39.4Β°C). While patients may exhibit fever, it is usually mild and self-limiting.
**Option D:** This statement is incorrect because Q fever is not transmitted through contact with infected animals. While animals can harbor *Coxiella burnetii*, transmission to humans typically occurs through inhalation of aerosolized particles.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that Q fever can be transmitted through inhalation of aerosolized particles from infected animals, and the bacteria can form highly resistant spores that can persist in the environment for long periods.
**Correct Answer:** A.
