The Centers for Disease Control and Prevention (CDC) today confirmed additional travel-related infections of 2019 Novel Coronavirus (2019-nCoV) in the United States, this time in Arizona and California. These patients recently returned to the U.S. from Wuhan, China, where an outbreak of respiratory illness caused by a novel coronavirus has been ongoing since December 2019. This brings the total number of 2019-nCoV infections detected in the United States to five.
Based on the patient’s travel history and symptoms, healthcare professionals suspected 2019-nCoV. Clinical specimens were collected and sent to CDC, where laboratory testing confirmed infection with 2019-nCoV. Investigations are underway to determine where these patients went after returning to the United States and any close contacts who were possibly exposed. CDC teams have been deployed to support these efforts.
It is likely there will be more cases reported in the U.S. in the coming days and weeks, likely including person-to-person spread. In previous outbreaks with MERS and SARS, the two other coronaviruses that have jumped the species barrier to cause severe illness in people, person-to-person spread has been seen, including among healthcare workers caring for patients ill with coronavirus infection.
