IMPORTANCE Limited data on vertical and perinatal transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and health outcomes of neonates born to mothers with symptomatic or asymptomatic coronavirus disease 2019 (COVID-19) are available. Studies are needed to inform evidence-based infection prevention and control (IP&C) policies. OBJECTIVE To describe the outcomes of neonates born to mothers with perinatal SARS-CoV-2 infection and the IP&C practices associated with these outcomes. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort analysis reviewed the medical records for maternal and newborn data for all 101 neonates born to 100 mothers positive for or with suspected SARS-CoV-2 infection from March 13 to April 24, 2020. Testing for SARS-CoV-2 was performed using Cobas (Roche Diagnostics) or Xpert Xpress (Cepheid) assays. Newborns were admitted to well-baby nurseries (WBNs) (82 infants) and neonatal intensive care units (NICUs) (19 infants) in 2 affiliate hospitals at a large academic medical center in New York, New York. Newborns from the WBNs roomed-in with their mothers, who were required to wear masks. Direct breastfeeding after appropriate hygiene was encouraged. EXPOSURES Perinatal exposure to maternal asymptomatic/mild vs severe/critical COVID-19. MAIN OUTCOMES AND MEASURES The primary outcome was newborn SARS-CoV-2 testing results. Maternal COVID-19 status was classified as asymptomatic/mildly symptomatic vs severe/critical. Newborn characteristics and clinical courses were compared across maternal COVID-19 severity. RESULTS In total, 141 tests were obtained from 101 newborns (54 girls [53.5%]) on 0 to 25 days of life (DOL-0 to DOL-25) (median, DOL-1; interquartile range [IQR], DOL-1 to DOL-3). Two newborns had indeterminate test results, indicative of low viral load (2.0%; 95% CI, 0.2%-7.0%); 1 newborn never underwent retesting but remained well on follow-up, and the other had negative results on retesting. Maternal severe/critical COVID-19 was associated with newborns born approximately 1 week earlier (median gestational age, 37.9 [IQR, 37.1-38.4] vs 39.1 [IQR, 38.3-40.2] weeks; P = .02) and at increased risk of requiring phototherapy (3 of 10 [30.0%] vs 6 of 91 [7.0%]; P = .04) compared with newborns of mothers with asymptomatic/mild COVID-19. Fifty-five newborns were followed up in a new COVID-19 Newborn Follow-up Clinic at DOL-3 to DOL-10 and remained well. Twenty of these newborns plus 3 newborns followed up elsewhere had 32 nonroutine encounters documented at DOL-3 to DOL-25, and none had evidence of SARS-CoV-2 infection, including 6 with negative retesting results. CONCLUSIONS AND RELEVANCE No clinical evidence of vertical transmission was identified in 101 newborns of mothers positive for or with suspected SARS-CoV-2 infection, despite most newborns rooming-in and direct breastfeeding practices.
As the COVID-19 pandemic continues to spread worldwide, it is crucial that we determine populations that are at-risk and develop appropriate clinical care policies to protect them. While several respiratory illnesses are known to seriously impact pregnant women and newborns, preliminary data on the novel SARS-CoV-2 Coronavirus suggest that these groups are no more at-risk than the general population. Here, we review the available literature on newborns born to infected mothers and show that newborns of mothers with positive/suspected SARS-CoV-2 infection rarely acquire the disease or show adverse clinical outcomes. With this evidence in mind, it appears that strict postnatal care policies, including separating mothers and newborns, discouraging breastfeeding, and performing early bathing, may be more likely to adversely impact newborns than they are to reduce the low risk of maternal transmission of SARS-CoV-2 or the even lower risk of severe COVID-19 disease in otherwise healthy newborns.
During the early months of the COVID-19 pandemic, infection prevention and control (IP&C) for women in labor and mothers and newborns during delivery and receiving post-partum care was quite challenging for staff, patients, and support persons due to a relative lack of evidence-based practices, high rates of community transmission, and shortages of personal protective equipment (PPE). We present our IP&C policies and procedures for the obstetrical population developed from mid-March to mid-May 2020 when New York City served as the epicenter of the pandemic in the U.S. For patients, we describe screening for COVID-19, testing for SARS-CoV-2, and clearing patients from COVID-19 precautions. For staff, we address self-monitoring for symptoms, PPE in different clinical scenarios, and reducing staff exposures to SARS-CoV-2. For visitors/support persons, we address limiting them in labor and delivery, the postpartum units, and the NICU to promote staff and patient safety. We describe management of SARS-CoV-2-positive mothers and their newborns in both the well-baby nursery and in the neonatal ICU. Notably, in the well-baby nursery we do not separate SARS-CoV-2-positive mothers from their newborns, but emphasize maternal mask use and social distancing by placing newborns in isolates and asking mothers to remain 6 feet away unless feeding or changing their newborn. We also encourage direct breastfeeding and do not advocate early bathing. Newborns of SARS-CoV-2-positive mothers are considered persons under investigation (PUIs) until 14 days of life, the duration of the incubation period for SARS-CoV-2. We share two models of community-based care for PUI neonates. Finally, we provide our strategies for enhancing communication and education during the early months of the pandemic.
We describe a premature infant with congenital measles. Laboratory testing confirmed measles in the mother (polymerase chain reaction-and IgM-positive) and congenital measles in the infant (polymerase chain reaction-positive, culture-positive and IgM-positive). The infant never developed a rash, pneumonia, or neurologic complications. This case supports using compatible laboratory findings to diagnose congenital measles in infants without clinical manifestations of measles.
Background: Measles can cause miscarriages and preterm birth in nonimmune pregnant women. During the 2018–2019 measles outbreak in New York, a woman with measles delivered an extremely low birth weight preterm infant at our Women and Children’s Hospital. We describe our measles preparedness strategies and infection prevention and control (IPC) management relevant to congenital measles. Methods: Because of the measles outbreak, in Q4 2018, IPC verified measles immunity in all obstetric and pediatric staff, per state regulations, and recommended determining the measles immune status of all pregnant women. To prevent measles exposure, visitor restrictions for the neonatal intensive care unit (NICU) were implemented (May 2019); only 3 visitors were permitted for each infant, including parents. All visitors had to provide written documentation of immunity to measles, regardless of epidemiologic risk factors or receive an MMR vaccine prior to visiting. New York state and New York City health departments performed measles diagnostic testing for maternal and infant specimens. Results: Our hospital was informed of the imminent transfer of a woman in preterm labor with suspected measles. To avoid any exposure, the mother was masked in the ambulance bay and taken by commandeered elevator to the obstetrical operating room suite, which was cleared of other patients. She delivered by C-section and was transferred to an airborne infection isolation (AII) room. The 25-week-gestation infant was transported by isolette to the NICU and was placed on AII. Testing confirmed measles in the mother (measles PCR- and IgM-positive) and congenital measles in the infant (Table 1). The mother was allowed to visit the NICU when her respiratory symptoms and rash resolved, as confirmed by her provider, ~10 days after discharge. The infant never developed a rash, pneumonia, or neurologic findings. AII was discontinued on day of life 61 in consultation with the health departments. The infant was discharged at ~36 weeks gestation. No secondary cases of measles occurred among patients, visitors, or staff. Conclusions: We safely cared for an extremely preterm infant with congenital measles. Laboratory testing suggested prolonged presence of measles virus, but it is unknown how long an infant in the NICU should remain on AII. The current Council of State and Territorial Epidemiologists case definition for measles requires the presence of rash. This case provides support to revise this case definition if laboratory findings are consistent with congenital measles.Funding: NoneDisclosures: None
