Most common viral disease affecting parotid glands
**Core Concept**
Mumps is a viral infection caused by the mumps virus, leading to inflammation of the parotid glands. The parotid glands are responsible for producing saliva, and their inflammation can cause symptoms such as swelling, pain, and fever.
**Why the Correct Answer is Right**
The mumps virus primarily targets the salivary glands, including the parotid glands, and causes an immune response leading to inflammation. This results in symptoms such as swelling, pain, and difficulty swallowing. The virus replicates in the epithelial cells of the salivary glands, leading to the release of pro-inflammatory cytokines and chemokines, which contribute to the inflammatory response.
**Why Each Wrong Option is Incorrect**
**Option A:** Meningitis is an infection of the meninges, which are the protective membranes surrounding the brain and spinal cord, and is not directly related to the parotid glands.
**Option B:** Viral pharyngitis is an inflammation of the pharynx caused by a viral infection, but it does not specifically target the parotid glands.
**Option C:** Herpangina is a viral infection that causes small, painful blisters in the back of the throat, but it is not primarily associated with parotid gland inflammation.
**Clinical Pearl / High-Yield Fact**
Mumps is a highly contagious disease that can be prevented through vaccination, and its symptoms can be managed with supportive care, such as pain relief and hydration.
**Correct Answer: D. Mumps**
