From the Overview: "This webpage provides information for workers and employers about the evolving coronavirus outbreak first identified in Wuhan City, Hubei Province, China. The information includes links to interim guidance and other resources for preventing exposures to, and infections with, 2019 novel coronavirus (2019-nCoV). According to the U.S. Department of Health and Human Services/Centers for Disease Control and Prevention (CDC), Chinese authorities identified the new coronavirus, which has resulted in confirmed human infections in China and exported cases outside of China, including in the United States, Thailand, Japan, and South Korea. China also has reported spread of the virus from infected patients to healthcare workers. There is no evidence of ongoing transmission of 2019-nCoV in the United States at this time. Without sustained human-to-human transmission, most American workers are not at significant risk of infection. However, workers involved in airline operations (including cabin crewmembers), healthcare (including clinical laboratory personnel), and border protection may have exposure to travelers infected with the virus in China or other affected areas. Business travelers from the United States who visit areas abroad where the virus is spreading may also be at some risk of exposure."
