From MedicalXpress:

Person-to-person transmission of SARS-CoV-2 occurred between two people with prolonged, unprotected exposure while the first patient was symptomatic. Despite active monitoring and testing of 372 contacts of both cases, no further transmission was detected

New research published in The Lancet, describes in detail the first locally-transmitted case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19, in the USA, from a woman who had recently travelled to China and transmitted the infection to her husband. No further transmission was detected, despite monitoring contacts for symptoms and testing all those who developed fever, cough, or shortness of breath, as well as a sample of asymptomatic healthcare professionals who had come into contact with the patients.

On January 23, 2020, Illinois reported the state's first laboratory-confirmed case (index case) of COVID-19 in a woman in her 60s who returned from Wuhan, China in mid-January, 2020. Subsequently, the first evidence of secondary transmission in the USA was reported on January 30, when her husband, who had not travelled outside the USA but had frequent, close contact with his wife since her return, tested positive for SARS-CoV-2.

"This report suggests that person-to-person transmission of SARS-CoV-2 might be most likely to occur through unprotected, prolonged exposure to an individual with symptomatic COVID-19", says Dr. Jennifer Layden, Chief Medical Officer of the Chicago Department of Public Health, USA, who co-led the research. "Our experience of limited transmission of SARS-CoV-2 differs from Wuhan where transmission has been reported to occur across the wider community and among healthcare professionals, and from experiences of other similar coronaviruses. Nevertheless, healthcare facilities should rapidly triage and isolate individuals suspected of having COVID-19, and notify infection prevention services and local health departments for support in testing, management, and containment efforts."

1. It's pretty clear Covid-19 has been present and spreading in the US since at least mid-January.
