Clin Infect Dis 2023 77 (2) 212-219 BACKGROUND: Public health programs varied in ability to reach people with COVID-19 and their contacts to encourage separation from others. For both adult cases of COVID-19 and contacts, we estimated the impact of contact tracing activities on separation behaviors from January, 2020 until March, 2022. METHODS: We used a probability-based panel survey of a nationally representative sample to gather data for estimates and comparisons. RESULTS: An estimated 64,255,351 adults reported a positive SARS-CoV-2 test result; 79.6% isolated for >5 days, 60.2% isolated for >10 days, and 79.2% self-notified contacts. 24,057,139 (37.7%) completed a case investigation and 46.2% reported contacts to health officials. More adults who completed a case investigation isolated than adults who did not (>5 days, 82.6%; >10 days, 69.8% versus >5 days, 78.2% and >10 days 54.8%; p-values for both measures <0.05).84,946,636 adults were a contact to a COVID-19 case; 73.1% learned of their exposure directly from a case; 49.4% quarantined for >5 days, 18.7% quarantined for >14 days, and 13.5% completed a contact tracing call. More who completed a contact tracing call quarantined than those who did not (>5 days, 61.2%; >14 days, 25.2% versus >5 days, 48.5%; >14 days, 18.0%; p-values for both measures <0.05). CONCLUSIONS: Engagement in contact tracing positively correlated with isolation and quarantine. However, most adults with COVID-19 isolated and self-notified contacts regardless of whether the public health workforce was able to reach them. Identifying and reaching contacts was challenging, and limited the ability to promote quarantining, and testing. |
Establishing a timeline to discontinue routine testing of asymptomatic pregnant women for Zika virus infection - American Samoa, 2016-2017

MMWR Morb Mortal Wkly Rep 2017 66 (11) 299-301 The first patients with laboratory-confirmed cases of Zika virus disease in American Samoa had symptom onset in January 2016. In response, the American Samoa Department of Health (ASDoH) implemented mosquito control measures, strategies to protect pregnant women, syndromic surveillance based on electronic health record (EHR) reports, Zika virus testing of persons with one or more signs or symptoms of Zika virus disease (fever, rash, arthralgia, or conjunctivitis), and routine testing of all asymptomatic pregnant women in accordance with CDC guidance. All collected blood and urine specimens were shipped to the Hawaii Department of Health Laboratory for Zika virus testing and to CDC for confirmatory testing. Early in the response, collection and testing of specimens from pregnant women was prioritized over the collection from symptomatic nonpregnant patients because of limited testing and shipping capacity. The weekly numbers of suspected Zika virus disease cases declined from an average of six per week in January-February 2016 to one per week in May 2016. By August, the EHR-based syndromic surveillance indicated a return to pre-outbreak levels. The last Zika virus disease case detected by real-time, reverse transcription-polymerase chain reaction (rRT-PCR) occurred in a patient who had symptom onset on June 19, 2016. In August 2016, ASDoH requested CDC support in assessing whether local transmission had been reduced or interrupted and in proposing a timeline for discontinuation of routine testing of asymptomatic pregnant women. An end date (October 15, 2016) was determined for active mosquito-borne transmission of Zika virus and a timeline was developed for discontinuation of routine screening of asymptomatic pregnant women in American Samoa (conception after December 10, 2016, with permissive testing for asymptomatic women who conceive through April 15, 2017). |
