The Pennsylvania Department of Health (DOH) issued new guidance on October 19, 2026, requiring healthcare providers to immediately report suspected measles cases in pregnant patients or newborns to local health departments or the DOH [6][11]. This advisory comes as Pennsylvania has reported 1,286 confirmed measles cases across 42 counties as of October 19, 2026 [1][7].

This new directive aims to address a serious public health concern, as measles during pregnancy can lead to severe complications for both mother and baby, including miscarriage, early labor, low birth weight, and congenital measles in newborns [4][5]. Cases of congenital measles, where babies are born infected, have appeared in Pennsylvania for the first time in decades, with at least six babies born infected, two requiring intensive care, and one newborn dying shortly after birth [2][5].

## What the records show

On October 19, 2026, the Pennsylvania Department of Health alerted doctors about an increase in measles infections among pregnant women and a rise in congenital measles cases [2][5]. The alert mandates that providers caring for pregnant patients with suspected or confirmed measles, or evaluating newborns for possible congenital measles, must immediately report these cases to their local public health department or the Pennsylvania DOH [6][11]. The DOH can be reached at 877-PA-HEALTH (877-724-3258) for reporting and consultation [6][11].

The guidance also advises that unvaccinated pregnant women exposed to measles should receive immunoglobulin, an antibody treatment, within six days of exposure [3][11][19]. This treatment can reduce the chances of infection and lessen the severity of illness if they do get sick [19]. Since the outbreak began in April, 66 pregnant women in Pennsylvania have been diagnosed with measles [5]. The virus can transmit from a pregnant mother to her baby, and approximately one-third of babies born to mothers with measles rash onset within 14 days of delivery will develop congenital measles [6].

## The timeline

Pennsylvania's measles outbreak has been ongoing, with the state reporting 1,286 confirmed cases across 42 counties as of October 19, 2026 [1][7]. This number was an increase of 26 cases from the last update just days prior [7]. The state has also reported 247 hospitalizations and five measles-associated deaths [1]. On October 7, the Pennsylvania DOH submitted a formal Epi-Aid request to the Centers for Disease Control and Prevention (CDC) for assistance [15]. A CDC Epidemic Intelligence Service Officer joined the DOH on-site this week to support measles response efforts [1][15]. Nationally, the CDC reported 4,410 confirmed measles cases in the United States as of October 15, 2026 [13].

## What changed and for whom

The new guidance from the Pennsylvania DOH directly impacts healthcare providers, requiring them to alter their reporting procedures for measles cases involving pregnant patients and newborns [6][11]. For non-immune pregnant women, the advisory provides a critical six-day window for immunoglobulin treatment post-exposure, a measure that was not explicitly emphasized in this context before [3][11]. This shift in guidance reflects the escalating severity of the measles outbreak, particularly its impact on vulnerable populations like pregnant women and infants [4]. The state's health officials are now warning about congenital measles cases, which had not been recorded in the US for decades prior to this outbreak [2][4].

## What the subject has said publicly

The Pennsylvania Department of Health has issued an alert stating that measles cases during pregnancy are increasing and that congenital measles has been identified for the first time in decades [18]. The department also urged women to receive the measles, mumps, rubella (MMR) vaccine before pregnancy to protect against measles and congenital measles [3][4]. According to the DOH, measles during pregnancy is associated with increased maternal risk and can lead to serious health issues for newborns, including brain inflammation and death [4][6]. A DOH spokesperson stated that measles during pregnancy raises the risk of miscarriage, early labor, and low birth weight [5]. The DOH has also been working closely with the CDC, consulting specialists and securing federal guidance on issues like pregnancy-related information for healthcare providers [15].

## What we could not confirm

The CDC dashboard lists three measles deaths this year, despite Pennsylvania confirming five deaths [9][18]. The reason for this discrepancy in reported death tolls between state and federal agencies is not detailed in the available records [9]. The specific details about the locations or circumstances of the five measles-associated deaths in Pennsylvania, beyond the state's total, are also not available [1].
