What is already known about this topic?

Exposures to SARS-CoV-2 have commonly been described in congregate settings rather than broader community settings.

What is added by this report?

In a multistate telephone survey of 350 adult inpatients and outpatients who tested positive for SARS-CoV-2 infection, only 46% reported recent contact with a COVID-19 patient. Most participants’ contacts were a family member (45%) or a work colleague (34%). Two thirds of participants were employed; only 17% were able to telework.

What are the implications for public health practice?

Case investigation, contact tracing, and isolation of infected persons are needed to prevent ongoing community transmission, given the frequent lack of a known contact. Enhanced measures to ensure workplace safety, including social distancing and more widespread use of cloth face coverings, are warranted.
