Until Wednesday, Dallas County's 2016 and 2017 uptick in mumps activity was contained to cases that came in ones and twos. Despite North Texas seeing two and a half times more mumps cases in 2016 than the longstanding statewide average of about 20, Dallas County had yet to see an outbreak.
That streak appears to be over.
Late Wednesday afternoon, Dallas County Health and Human Services announced that 22 students and one staff member have been diagnosed with mumps at a North Texas high school. While it's impossible to know if any of the high school cases overlap, three high school cases announced in February — DCHHS keeps tight lips with regard to any information that could identify potential patients — Wednesday's announcement does seem to add at least 20 cases to the 10 that had already been recorded by DCHHS so far this year.
DCHHS warned local healthcare providers Wednesday that they expect additional mumps cases in the county, and that doctors should be on the lookout for patients exhibiting fever, headache and swelling of the salivary glands, fatigue, muscle aches and loss of appetite — all of which are potential symptoms of mumps.
