There are no specific 7 symptoms of mumps in adults. Common symptoms include enlarged parotid glands, sore throat and fever. 1. Enlarged parotid gland: Mumps is an infectious disease caused by the mumps virus. After an attack, the parotid gland may become inflamed, red, swollen or painful, resulting in an enlarged parotid gland. The enlarged parotid area may also have reddening of the skin. 2. Sore throat: The parotid gland is located around the earlobe, and inflammation will gradually cause swelling and pain from the earlobe downward. The area is close to the throat, so it can also irritate the mucous membrane of the throat and cause pain and inflammation during an attack. 3. Fever: Mumps is a contagious disease caused by a viral infection. The most typical complication is fever, both localized in the parotid gland and generalized, which needs to be treated promptly. Mumps itself is contagious, so you need to seek medical attention and personal protection after an attack.
