Oh, now it's not just measles that is spreading.
From the Idaho Statesman:
Mumps broke out in September at the University of Idaho's Moscow campus.
Since then, the illness has spread from north Idaho. Idaho now has 21 confirmed and probable cases, including six in the Boise area, according to the Idaho Department of Health and Welfare. Two cases in Washington also are associated with the outbreak.
Mumps is a contagious virus that spreads from person-to-person via droplets of saliva or mucus from the mouth, nose, or throat of an infected person, usually when the person coughs, sneezes, or talks. An infected person can spread the virus before being sick. The virus is also spread when someone with mumps touches items or surfaces without washing their hands, and then someone else touches the same item or surface and rubs their mouth or nose.
Symptoms, which can appear up to 25 days after being exposed, may include fever, headache, muscle aches, tiredness, loss of appetite, and swollen or tender salivary glands under the ears on one or both sides of the head. The most common complication of mumps infection in adults is testicular inflammation, which can lead to infertility. Rare complications include meningitis, encephalitis, inflammation of the ovaries, and deafness. Anyone experiencing mumps symptoms should contact a healthcare professional. Nearly half of people with mumps have very mild or no symptoms and might not know they are infected.
