Due to the infectious nature of mumps and measles, it generally sweeps through entire neighborhoods and school disricts;
a reason for the sweep is that you or your children contract it as much as 10-18 days before the symptoms even show up.
Prior vaccination and school entry requirements may have already eliminated you , or your family being at risk.
One of the reasons why I updated on the infectious disease ping list is so that people are advised if it is found in their neighborhood,
or if they are at a family event where someone may be attending school in an infected area.
Many school districts require MMR vaccination (Measeles, Mumps, Rubella) prior to grammar school admission, and as shown in the earlier 11/11/16 report,
prior vaccination may require a "booster" shot, since peoples immune system may not have been activated.
YMMV
Thanks, TIK!
