Why it matters

Mumps is a highly contagious viral illness that can lead to serious complications if not properly contained. The public health advisory aims to raise awareness, encourage vaccination, and provide guidance to medical professionals and the community to limit the spread of the disease.

The details

The Berkeley Public Health Office said the incubation period for mumps is up to 25 days. The advisory urges medical professionals to test for mumps when diagnosing inflammation and swelling of the salivary glands, and to verify patients' measles, mumps, and rubella vaccination status. People with suspected or confirmed mumps must isolate for five days after the onset of salivary gland swelling and avoid school, childcare, extracurricular activities, and other congregate settings.
