The alarming rise in measles cases has finally reached Pittsburgh, with four cases confirmed after exposure to an unvaccinated adult with measles. These people visited the airport, grocery stores, a thrift store, a car rental agency and untold other venues, exposing untold other people. This has fueled reactions in the general public from righteous anger (how dare these idiots remain unvaccinated and endanger my vulnerable loved ones with a preventable serious disease?) to outright fear (I can’t take my infant/immunocompromised relative out of the house now!).
