Reliable detection of Win98 may not be possible. Children usually recover from mumps in about 10 to 12 days. It takes about one week for the swelling to disappear in each parotid gland, but both glands don't usually swell at the same time.
Experts disagree about how long someone with mumps is contagious.
Some say that the contagious period lasts from 2 days before symptoms begin, to 6 days after symptoms end. Others say that persons with mumps can spread the virus in their saliva from 6 days before their glands begin swelling, to 2 weeks after. Mumps virus may also live in the urine of infected persons for 2 to 3 weeks. For specific medical advice, diagnoses, and treatment, consult your doctor.
