RESUMO
Pregnant, postpartum, and lactating people, and infants have unique needs during public health emergencies, including nuclear and radiological incidents. This report provides information on the CDC Division of Reproductive Health's emergency preparedness and response activities to address the needs of women of reproductive age (aged 15-49 years), people who are pregnant, postpartum, or lactating, and infants during a radiation emergency. Highlighted preparedness activities include: (1) development of a quick reference guide to inform key questions about pregnant, postpartum, and lactating people, and infants during radiation emergencies; and (2) exercising the role of reproductive health experts during nuclear and radiological incident preparedness activities.

Objective(s): The opioid crisis affects the health and health care of pregnant and postpartum people and infants prenatally exposed to substances. A Learning Community (LC) among 15 states was implemented to improve services for these populations. States drafted action plans with goals, strategies, and activities. Materials and Methods: Qualitative data from action plans were analyzed to assess how reported activities aligned with focus areas each year. Year 2 focus areas were compared with year 1 to identify shifts or expansion of activities. States self-assessed progress at the LC closing meeting, reported goal completion, barriers and facilitators affecting goal completion, and sustainment strategies. Results: In year 2, many states included activities focused on access to and coordination of quality services (13 of 15 states) and provider awareness and training (11 of 15). Among 12 states participating in both years of the LC, 11 expanded activities to include at least one additional focus area, adding activities in financing and coverage of services (n = 6); consumer awareness and education (n = 5); or ethical, legal, and social considerations (n = 4). Of the 39 goals developed by states, 54% were completed, and of those not completed, 94% had ongoing activities. Barriers to goal completion included competing priorities and pandemic-related constraints, whereas facilitators involving use of the LC as a forum for information-sharing and leadership-supported goal completion. Sustainability strategies were continued provider training and partnership with Perinatal Quality Collaboratives. Conclusion: State LC participation supported sustainment of activities to improve health and health care for pregnant and postpartum people with opioid use disorder and infants prenatally exposed to substances.

Opioid use disorder (OUD) poses a significant public health concern impacting maternal and infant outcomes. In 2018, the Centers for Disease Control and Prevention (CDC) partnered with the Association of State and Territorial Health Officials (ASTHO) to develop the Opioid use disorder, Maternal outcomes, and Neonatal abstinence syndrome Initiative Learning Community (OMNI LC) to identify and disseminate best practices and strategies for implementing systems-level changes in state health departments to address OUD affecting pregnant and postpartum persons and infants prenatally exposed to opioids. In 2019, the OMNI LC incorporated a field placement approach that assigned temporary field placement staff in five select OMNI LC states to provide important linkages, facilitate information sharing, and strengthen capacity among state and local health departments and other partners supporting maternal and child health communities affected by the opioid crisis. Using an implementation science framework, the field placement approach was assessed using five implementation outcome measures: appropriateness, acceptability, implementation cost, sustainability, and feasibility. Written responses from the participating OMNI LC states on these implementation outcome measures were analyzed to (1) highlight key strategies used by field placement staff, (2) assess the implementation of the OMNI LC field placement approach within the context of implementation science, and (3) identify implementation barriers. This report describes the implementation of a temporary field placement approach and suggests that this approach could be replicated to enhance state and local capacity to respond to the opioid crisis or other high-consequence events.

BACKGROUND: There is a continuing risk for COVID-19 transmission in school settings while transmission is ongoing in the community, particularly among unvaccinated populations. To ensure that schools continue to operate safely and to inform implementation of prevention strategies, it is imperative to gain better understanding of the risk behaviors of staff and students. This secondary analysis describes the prevalence of COVID-19 risk behaviors in an exposed population of students and school staff in the pre-vaccine era and identifies associations between these behaviors and testing positive for SARS-CoV-2. METHODS: From December 2020-January 2021, school staff and students exposed to confirmed COVID-19 cases in a Georgia school district were tested for SARS-CoV-2 and surveyed regarding risk behaviors in and out of school. Prevalence of risk behaviors was described by age group and school level, and associations with SARS-CoV-2 positivity were identified using chi squared tests. RESULTS: Overall, 717 students and 79 school staff participated in the investigation; SARS-CoV-2 positivity was 9.2%. In the 2 weeks prior to COVID-19 exposure, 24% of participants reported unmasked indoor time at school, 40% attended social gatherings with non-household members, and 71% visited out-of-school indoor locations, including 19% who ate indoors in restaurants. Frequencies of risk behaviors increased by age. Among students, 17% participated in school sports, of whom 86% participated without a mask. SARS-CoV-2 positivity was significantly associated with school sports and unmasked time in sports. Among K-5 students, positivity was associated with exposure to a teacher index case. CONCLUSIONS: This analysis highlights the high prevalence of risk behaviors in an unvaccinated population exposed to COVID-19 in school and identifies an association between student sports participation and SARS-CoV-2 positivity. These findings illustrate the importance of school-level prevention measures to reduce SARS-CoV-2 transmission, including limiting close-contact indoor sports and promoting consistent mask use in unvaccinated individuals. Future research could explore the role of community vaccination programs as a strategy to reduce COVID-19 transmission and introductions into school settings.

OBJECTIVE: To assess consistency of state neonatal risk-appropriate care policies with the 2012 AAP policy seven years post-publication. STUDY DESIGN: Systematic, web-based review of all publicly available 2019 state neonatal levels of care policies. Information on infant risk (gestational age, birth weight), technology and equipment capabilities, and availability of specialty staffing used to define neonatal levels of care was extracted for review. RESULT: Half of states (50%) had a neonatal risk-appropriate care policy. Of those states, 88% had language consistent with AAP-defined Level I criteria, 80% with Level II, 56% with Level III, and 55% with Level IV. Comparing policies (2014-2019), consistency increased in state policies among all levels of care with the greatest increase among level IV criteria. CONCLUSION: States improved consistency of policy language by each level of care, though half of states still lack policy to provide minimum standards of care to the most vulnerable infants.

BACKGROUND: To inform prevention strategies, we assessed the extent of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission and settings in which transmission occurred in a Georgia public school district. METHODS: During 1 December 2020-22 January 2021, SARS-CoV-2-infected index cases and their close contacts in schools were identified by school and public health officials. For in-school contacts, we assessed symptoms and offered SARS-CoV-2 reverse-transcription polymerase chain reaction (RT-PCR) testing; performed epidemiologic investigations and whole-genome sequencing to identify in-school transmission; and calculated secondary attack rate (SAR) by school setting (eg, sports, elementary school classroom), index case role (ie, staff, student), and index case symptomatic status. RESULTS: We identified 86 index cases and 1119 contacts, 688 (61.5%) of whom received testing. Fifty-nine of 679 (8.7%) contacts tested positive; 15 of 86 (17.4%) index cases resulted in ≥2 positive contacts. Among 55 persons testing positive with available symptom data, 31 (56.4%) were asymptomatic. Highest SARs were in indoor, high-contact sports settings (23.8% [95% confidence interval {CI}, 12.7%-33.3%]), staff meetings/lunches (18.2% [95% CI, 4.5%-31.8%]), and elementary school classrooms (9.5% [95% CI, 6.5%-12.5%]). The SAR was higher for staff (13.1% [95% CI, 9.0%-17.2%]) vs student index cases (5.8% [95% CI, 3.6%-8.0%]) and for symptomatic (10.9% [95% CI, 8.1%-13.9%]) vs asymptomatic index cases (3.0% [95% CI, 1.0%-5.5%]). CONCLUSIONS: Indoor sports may pose a risk to the safe operation of in-person learning. Preventing infection in staff members, through measures that include coronavirus disease 2019 vaccination, is critical to reducing in-school transmission. Because many positive contacts were asymptomatic, contact tracing should be paired with testing, regardless of symptoms.

The opioid crisis has impacted vulnerable populations, specifically pregnant and postpartum women, and infants prenatally exposed to substances, including infants with Neonatal Abstinence Syndrome. Lack of access to clinical and social services; potential stigma or discrimination; and lack of resources for provision of services, including screening and treatment, have impacted the health of these populations. In 2018, using a systems change approach, the Association of State and Territorial Health Officials (ASTHO) and the Centers for Disease Control and Prevention (CDC) convened an Opioid use disorder, Maternal outcomes, Neonatal abstinence syndrome Initiative Learning Community (OMNI LC) that included other federal agencies, national clinical and nonclinical organizations, and 12 state leadership groups. The purpose of the OMNI LC was to determine areas of focus and identify strategies and best practices for implementing systems change to improve maternal and infant outcomes associated with opioid use disorder (OUD) during the perinatal period. Activities included in-person convenings with policy goal action plan development, virtual learning sessions, intensive technical assistance (TA), and temporary field placements. The OMNI LC partnering agencies and state teams met bimonthly for the first year of the initiative. At the in-person convening, state teams identified barriers to developing and implementing systems change in activity-specific action plans within five areas of focus: financing and coverage; access to and coordination of quality services; provider training and awareness; ethical, legal, and social considerations; and data, monitoring, and evaluation. State teams also identified stakeholder partnerships as a necessary component of strategy development in all areas of focus. Four virtual learning sessions were conducted on the areas of focus identified by state teams, and ASTHO conducted three intensive TA opportunities, and five states were identified for temporary field placement. To successfully address the impact of the opioid crisis on pregnant and postpartum women and infants, states developed innovative strategies focused on increasing support, services, and resources. Moving forward, state teams will participate in two additional in-person meetings, continue to identify barriers to the work, refine and customize action plans, and set new goals, to effect broad-ranging systems change for these vulnerable populations.

Since 1999, the rate of opioid use disorder (OUD) has more than quadrupled, from 1.5 per 1,000 delivery hospitalizations to 6.5 (1), with similar increases in incidence of neonatal abstinence syndrome (NAS) observed for infants (from 2.8 per 1,000 live births to 14.4) among Medicaid-insured deliveries (2). CDC's response to the opioid crisis involves strategies to prevent opioid overdoses and related harms by building state capacity and supporting providers, health systems, and payers.* Recognizing systems gaps in provision of perinatal care and services, CDC partnered with the Association of State and Territorial Health Officials (ASTHO) to launch the Opioid Use Disorder, Maternal Outcomes, and Neonatal Abstinence Syndrome Initiative Learning Community (OMNI LC). OMNI LC supports systems change and capacity building in 12 states. Qualitative data from participating states were analyzed to identify strategies, barriers, and facilitators for capacity building in state-defined focus areas. Most states focused on strategies to expand access to and coordination of quality services (10 of 12) or increase provider awareness and training (nine of 12). Fewer states focused on data, monitoring, and evaluation (four of 12); financing and coverage (three of 12); or ethical, legal, and social considerations (two of 12). By building capacity to strengthen health systems, state-identified strategies across all focus areas might improve the health trajectory of mothers, infants, and families affected by the U.S. opioid crisis.

Ensuring access to and promoting use of effective contraception have been identified as important strategies for preventing unintended pregnancy (1). The importance of ensuring resources to prevent unintended pregnancy in the context of public health emergencies was highlighted during the 2016 Zika virus outbreak when Zika virus infection during pregnancy was identified as a cause of serious birth defects (2). Accordingly, CDC outlined strategies for state, local, and territorial jurisdictions to consider implementing to ensure access to contraception (3). To update previously published contraceptive use estimates* among women at risk for unintended pregnancy and to estimate the number of women with ongoing or potential need for contraceptive services,§,¶ data on contraceptive use were collected during September-December 2016 through the Behavioral Risk Factor Surveillance System (BRFSS). Results from 21 jurisdictions indicated that most women aged 18-49 years were at risk for unintended pregnancy (range across jurisdictions = 57.4%-76.8%). Estimates of the number of women with ongoing or potential need for contraceptive services ranged from 368 to 617 per 1,000 women aged 18-49 years. The percentage of women at risk for unintended pregnancy using a most or moderately effective contraceptive method** ranged from 26.1% to 65.7%. Jurisdictions can use this information to estimate the number of women who might seek contraceptive services and to plan and evaluate efforts to increase contraceptive use. This information is particularly important in the context of public health emergencies, such as the recent Zika virus outbreak, which have been associated with increased risk for adverse maternal-infant outcomes (2,4-6) and have highlighted the importance of providing women and their partners with resources to prevent unintended pregnancy.

INTRODUCTION: Zika virus infection during pregnancy causes serious birth defects and might be associated with neurodevelopmental abnormalities in children. Early identification of and intervention for neurodevelopmental problems can improve cognitive, social, and behavioral functioning. METHODS: Pregnancies with laboratory evidence of confirmed or possible Zika virus infection and infants resulting from these pregnancies are included in the U.S. Zika Pregnancy and Infant Registry (USZPIR) and followed through active surveillance methods. This report includes data on children aged ≥1 year born in U.S. territories and freely associated states. Receipt of reported follow-up care was assessed, and data were reviewed to identify Zika-associated birth defects and neurodevelopmental abnormalities possibly associated with congenital Zika virus infection. RESULTS: Among 1,450 children of mothers with laboratory evidence of confirmed or possible Zika virus infection during pregnancy and with reported follow-up care, 76% had developmental screening or evaluation, 60% had postnatal neuroimaging, 48% had automated auditory brainstem response-based hearing screen or evaluation, and 36% had an ophthalmologic evaluation. Among evaluated children, 6% had at least one Zika-associated birth defect identified, 9% had at least one neurodevelopmental abnormality possibly associated with congenital Zika virus infection identified, and 1% had both. CONCLUSION: One in seven evaluated children had a Zika-associated birth defect, a neurodevelopmental abnormality possibly associated with congenital Zika virus infection, or both reported to the USZPIR. Given that most children did not have evidence of all recommended evaluations, additional anomalies might not have been identified. Careful monitoring and evaluation of children born to mothers with evidence of Zika virus infection during pregnancy is essential for ensuring early detection of possible disabilities and early referral to intervention services.

BACKGROUND: Ships destined for, or departing from, U.S. ports of entry must report certain signs and symptoms of potentially communicable diseases of public health interest among travelers to the Division of Global Migration and Quarantine (DGMQ) at the Centers for Disease Control and Prevention. METHODS: We reviewed ships' varicella case and outbreak reports from January 2010 through December 2015. RESULTS: DGMQ received 967 reports of varicella and 13 reports of herpes zoster. Most varicella case-patients were 20-49 years of age (84.7%, 472/557) and were cruise ship crew members (78.4%, 758/967). Most often, cruise ship crew member case-patients were born in or held passports from Indonesia (21.7%, 80/369), Philippines (17.6%, 65/369), or India (17.3%, 64/369). Ninety-nine varicella outbreaks were reported, including 439 varicella cases and one herpes zoster case; 97 (98.0%) outbreaks occurred on cruise ships, and 90.2% of associated cases were among crew members (397/440). Most varicella cases were in crew members, who are adults often from tropical regions where varicella immunity is acquired later in childhood or young adulthood or without varicella vaccination programs. CONCLUSION: Varicella vaccination as appropriate for susceptible travelers, particularly crew members, before maritime travel may decrease risk of varicella infection and prevent outbreaks on ships.

BACKGROUND: Deaths and certain illnesses onboard ships arriving at US ports are required to be reported to the US Centers for Disease Control and Prevention (CDC), and notifications of certain illnesses are requested. METHODS: We performed a descriptive analysis of required maritime illness and death reports of presumptive diagnoses and requested notifications to CDC's Division of Global Migration and Quarantine, which manages CDC's Quarantine Stations, from January 2010 to December 2014. RESULTS: CDC Quarantine Stations received 2891 individual maritime case reports: 76.8% (2221/2891) illness reports, and 23.2% (670/2891) death reports. The most frequent individual illness reported was varicella (35.9%, 797/2221) and the most frequently reported causes of death were cardiovascular- or pulmonary-related conditions (79.6%, 533/670). There were 7695 cases of influenza-like illness received within aggregate notifications. CDC coordinated 63 contact investigations with partners to identify 972 contacts; 88.0% (855/972) were notified. There was documentation of 6.5% (19/293) receiving post-exposure prophylaxis. Three pertussis contacts were identified as secondary cases; and one tuberculosis contact was diagnosed with active tuberculosis. CONCLUSION: These data provide a picture of US maritime illness and death reporting and response. Varicella reports are the most frequent individual disease reports received. Contact investigations identified few cases of disease transmission.

Zika virus infection during pregnancy remains a serious health threat in Puerto Rico. Infection during pregnancy can cause microcephaly, brain abnormalities, and other severe birth defects (1). From January 1, 2016 through March 29, 2017, Puerto Rico reported approximately 3,300 pregnant women with laboratory evidence of possible Zika virus infection (2). There is currently no vaccine or intervention to prevent the adverse effects of Zika virus infection during pregnancy; therefore, prevention has been the focus of public health activities, especially for pregnant women (3). CDC and the Puerto Rico Department of Health analyzed data from the Pregnancy Risk Assessment Monitoring System Zika Postpartum Emergency Response (PRAMS-ZPER) survey conducted from August through December 2016 among Puerto Rico residents with a live birth. Most women (98.1%) reported using at least one measure to avoid mosquitos in their home environment. However, only 45.8% of women reported wearing mosquito repellent daily, and 11.5% reported wearing pants and shirts with long sleeves daily. Approximately one third (38.5%) reported abstaining from sex or using condoms consistently throughout pregnancy. Overall, 76.9% of women reported having been tested for Zika virus by their health care provider during the first or second trimester of pregnancy. These results can be used to assess and refine Zika virus infection prevention messaging and interventions for pregnant women and to reinforce measures to promote prenatal testing for Zika.

Pregnant women living in or traveling to areas with local mosquito-borne Zika virus transmission are at risk for Zika virus infection, which can lead to severe fetal and infant brain abnormalities and microcephaly (1). In February 2016, CDC recommended 1) routine testing for Zika virus infection of asymptomatic pregnant women living in areas with ongoing local Zika virus transmission at the first prenatal care visit, 2) retesting during the second trimester for women who initially test negative, and 3) testing of pregnant women with signs or symptoms consistent with Zika virus disease (e.g., fever, rash, arthralgia, or conjunctivitis) at any time during pregnancy (2). To collect information about pregnant women with laboratory evidence of recent possible Zika virus infection* and outcomes in their fetuses and infants, CDC established pregnancy and infant registries (3). During January 1, 2016-April 25, 2017, U.S. territories with local transmission of Zika virus reported 2,549 completed pregnancies§ (live births and pregnancy losses at any gestational age) with laboratory evidence of recent possible Zika virus infection; 5% of fetuses or infants resulting from these pregnancies had birth defects potentially associated with Zika virus infection¶ (4,5). Among completed pregnancies with positive nucleic acid tests confirming Zika infection identified in the first, second, and third trimesters, the percentage of fetuses or infants with possible Zika-associated birth defects was 8%, 5%, and 4%, respectively. Among liveborn infants, 59% had Zika laboratory testing results reported to the pregnancy and infant registries. Identification and follow-up of infants born to women with laboratory evidence of recent possible Zika virus infection during pregnancy permits timely and appropriate clinical intervention services (6).

BACKGROUND: In collaboration with state, tribal, local, and territorial health departments, CDC established the U.S. Zika Pregnancy Registry (USZPR) in early 2016 to monitor pregnant women with laboratory evidence of possible recent Zika virus infection and their infants. METHODS: This report includes an analysis of completed pregnancies (which include live births and pregnancy losses, regardless of gestational age) in the 50 U.S. states and the District of Columbia (DC) with laboratory evidence of possible recent Zika virus infection reported to the USZPR from January 15 to December 27, 2016. Birth defects potentially associated with Zika virus infection during pregnancy include brain abnormalities and/or microcephaly, eye abnormalities, other consequences of central nervous system dysfunction, and neural tube defects and other early brain malformations. RESULTS: During the analysis period, 1,297 pregnant women in 44 states were reported to the USZPR. Zika virus-associated birth defects were reported for 51 (5%) of the 972 fetuses/infants from completed pregnancies with laboratory evidence of possible recent Zika virus infection (95% confidence interval [CI] = 4%-7%); the proportion was higher when restricted to pregnancies with laboratory-confirmed Zika virus infection (24/250 completed pregnancies [10%, 95% CI = 7%-14%]). Birth defects were reported in 15% (95% CI = 8%-26%) of fetuses/infants of completed pregnancies with confirmed Zika virus infection in the first trimester. Among 895 liveborn infants from pregnancies with possible recent Zika virus infection, postnatal neuroimaging was reported for 221 (25%), and Zika virus testing of at least one infant specimen was reported for 585 (65%). CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: These findings highlight why pregnant women should avoid Zika virus exposure. Because the full clinical spectrum of congenital Zika virus infection is not yet known, all infants born to women with laboratory evidence of possible recent Zika virus infection during pregnancy should receive postnatal neuroimaging and Zika virus testing in addition to a comprehensive newborn physical exam and hearing screen. Identification and follow-up care of infants born to women with laboratory evidence of possible recent Zika virus infection during pregnancy and infants with possible congenital Zika virus infection can ensure that appropriate clinical services are available.
