Can mumps heal on its own without treatment?
In general, mild cases of mumps may resolve spontaneously, but without treatment, severe cases or those with complications can worsen. The need for treatment should be determined based on individual circumstances. If in doubt, it is advisable to seek medical advice early. Detailed analysis is as follows:

If the mumps is mild and the patient has a strong immune system without significant symptoms such as fever or headache, recovery may occur within one to two weeks without specific treatment. In such cases, the body's immune system gradually clears the virus, and the swelling of the salivary glands will subside over time. However, isolation is necessary during this period to prevent spreading the virus to others, along with adequate rest and a light diet.
For severe mumps accompanied by high fever, intense headache, or complications such as orchitis or pancreatitis, lack of treatment may lead to disease progression. The virus could further affect other organs, causing more serious health issues or even long-term complications. These cases require prompt medical attention, with medication used to control symptoms and prevent complications.
After onset of mumps, symptoms should be closely monitored. Immediate medical care is needed if persistent high fever or unusual pain occurs. Patients should remain isolated during illness and avoid crowded places. After recovery, efforts should focus on improving physical fitness to reduce the risk of reinfection.
