Population-based surveillance for birth defects potentially related to Zika virus infection including 3-year mortality and developmental outcomes, and Early Intervention Program service use-New York City, 2016 birth cohort.

BACKGROUND: In response to the 2015-2017 Zika virus outbreak, New York City (NYC) identified and monitored infants with birth defects potentially related to congenital Zika virus. METHODS: Administrative data matches were used to describe the birth characteristics of children born in 2016 meeting screening criteria for birth defects potentially related to congenital Zika virus infection relative to other NYC births and to monitor mortality and Early Intervention Program use through age 2. RESULTS: Among 120,367 children born in NYC in 2016, 463 met screening criteria and 155 met the Centers for Disease Control and Prevention's case definition for birth defects potentially related to congenital Zika virus infection (1.3 per 1000; 95% confidence interval [CI], 1.1-1.5). Post-neonatal deaths occurred among 7.7% of cases (12) and 5.2% of non-cases (8). Odds of referral to the Early intervention Program among children who met screening criteria were lower among children of mothers who were married (OR, 0.60; 95% CI, 0.37-0.97) and among children not classified as cases whose mothers were born in Latin America and the Caribbean (OR, 0.59; 95% CI, 0.37-1.09). DISCUSSION: Prevalence of birth defects potentially related to congenital Zika virus infection was similar to that seen in other jurisdictions without local transmission. Birth defects attributable to congenital Zika virus infection may also have been present among screened children who did not meet the case definition.

Continuity of Early Intervention Services in New York City During the COVID-19 Pandemic.

In response to COVID-19, the New York City Early Intervention (EI) Program rapidly transitioned from in-person to teletherapy services. We describe the timing of service resumption among children who received EI services between March 1 and March 17, 2020. The proportion of children who transitioned to teletherapy-only was 25% as of March 24, rising to 78% by July 6. By December 31, 2020, 87% of the cohort had resumed either teletherapy or in-person services. Child age, race, language, and neighborhood poverty all predicted service resumption timing. Children with a diagnosis of autism spectrum disorder were more likely to transition to teletherapy, and children with only 1-2 domains of delay were more likely to discontinue services altogether. Continuity of EI services during the COVID-19 public health emergency was a critical priority. Timely policy changes facilitated swift return to services and avoided exacerbation of the long-standing racial disparities in access to EI services.
