This article discusses the challenges of contact tracing among people experiencing homelessness. It suggests combining the traditional person-based approaches to contact tracing with location-based contact tracing approaches when conducting investigations among unhoused individuals. Location-based approaches collect data on the places people have visited in the past 48 hours, rather than the individuals with whom they interacted. Facility-wide testing and resources can be provided in locations where someone accessed support services.

The Public Health-Seattle and King County evaluated its case investigation and contract tracing program for effectiveness and found that contract tracing helped nearly three in four people surveyed stay in isolation. This demonstrates the value of contact tracing and case investigation as a public health tool for COVID-19 mitigation.

New York City’s Test & Trace Corps worked to reduce Covid-19 testing inequities by developing a mobile testing program focused on communities disproportionately affected by Covid-19. The model engaged community partners to determine the best methods of outreach and utilized multiple testing strategies. Based on the whether and community needs, free testing was offered outdoors, from vehicles, or at community spaces. Testing was both clinician-administered and patient-administered. Community organizations and organizers facilitated outreach to residents in their neighborhoods. The practice was successful in increasing access to testing, contact tracing, and isolation/aftercare support in these communities.

A mini-review that summarizes lessons learned from HIV among pregnant women and LGBTQI+ communities. The recommendations include: 1) de-stigmatization, 2) decentralized care, 3)contact-tracing and follow up, 4) use of technology/mobile/digital tools, 5) develop mechanisms to combine routine management of other diseases and COVID-19, and 6) community-specific interventions.

In northwest Arkansas, the Marshallese community has experienced a disproportionate COVID-19 burden. This response plan, funded by the CARES act, hired English/Marshallese bilingual staff to provide contact tracing, navigation, and other types of response. Staff that were not bilingual participated in cultural humility training.

In June 2020, Northwest Arkansas was a COVID-19 hotspot, with serious racial and ethnic disparities. Existing community-engaged partnerships utilized their collaborative capacity to address COVID-19 disparities in the Latinx and Pacific Islander communities. Eighteen key partners held weekly meetings and regular communication and developed four strategies: (1): health education (prevention, testing, quarantine, and follow-up care) and prevention (communication re: practices to reduce risk); (2) testing; (3) a dedicated contact tracing center with bilingual workers; (4) enhanced case management and supported quarantine.

This guidebook was designed to increase equity and access in COVID-19 testing and contact tracing in Virginia. The guidelines included a health equity framework, recommendations for working with communities, common barriers to COVID-19 testing faced by the most at-risk populations, and how to identify areas with unmet testing needs. Descriptions of how to determine appropriate interventions for testing, contact tracing, and building trusting community relationships are included.

This article discusses the effectiveness of a test-trace-quarantine model of COVID-19 response in lieu of mobility limiting interventions. A computer analysis was done using a program called Covasim to generate predictions of community impact, and real-world data was also collected showing a transition from mobility limiting interventions (such as school and work closures) to test-trace-quarantine interventions. Results indicate that this type of intervention can be successful in limiting the impact of COVID-19 when all parts of the model have strong performance.

This article summarizes COVID-19 mitigation within the Blackfeet Tribal Reservation and changes in incidence depending on the enforcement of masking, stay-at-home orders, and contact tracing. The combination of these efforts was associated with a 33-fold reduction in COVID-19 incidence from October 5 to November 7 in 2020.

This resource discusses Project: ACE-IT which is a school-based testing intervention implemented in Pennsylvania. The goal of the program was to reduce in-school transmission risks through routine testing for symptomatic and possibly asymptomatic staff and students. This program was originally adapted from a school-based program in Texas, and has expanded using a ‘train the trainer’ model with materials available on the website.
