Public health officials think that most of these recent cases can be attributed to a larger, ongoing outbreak that started in December 2014 among people who were exposed to measles at a California amusement park. The alert is a reminder that measles still affects people in the U.S. and that vaccination is the best protection against this highly contagious infection that can have serious consequences.

A rapid test for syphilis has been granted a waiver by the FDA for use in a wider variety of healthcare settings, such as emergency rooms, clinics, and other outpatient settings.
