Pennsylvania

The Pennsylvania Department of Health issued a health alert Monday over an increase in congenital measles cases, measles transmitted from a pregnant person to a newborn, a development not seen in the United States for decades. The alert comes as the state struggles with a large measles outbreak that has fueled the re-emergence of this preventable condition.

Pennsylvania has confirmed six measles-associated deaths as its outbreak reached 1,222 cases, up from 86 the week before, and the US Centers for Disease Control and Prevention said it will send a 'disease detective' and nearly $4 million to support the state's response. The CDC reported 4,410 measles cases nationally as of Friday, an increase of 330 in a week.
