The Center for Disease Control is closely monitoring an outbreak of respiratory illness caused by a novel (new) coronavirus (termed “2019-nCoV”) that was first detected in Wuhan City, Hubei Province, China and which continues to expand. Chinese health officials have reported hundreds of infections with 2019-nCoV in China, including outside of Hubei Province. A number of countries, including the United States, have been actively screening incoming travelers from Wuhan. Human infections with 2019-nCoV have been confirmed in other countries, including the United States. The United States announced their first infection with 2019-nCoV detected in a traveler returning from Wuhan on January 21, 2020.
Early on, many of the patients in the outbreak in Wuhan, China reportedly had some link to a large seafood and animal market, suggesting animal-to-person spread. However, a growing number of patients reportedly have not had exposure to animal markets. Investigations are ongoing to learn more, but person-to-person spread of 2019-nCoV is occurring. Some viruses are highly contagious (like measles), while other viruses are less so. It’s not clear yet how easily 2019-nCoV spreads from person-to-person. It’s important to know this in order to better assess the risk posed by this virus, and our investigation is ongoing. While CDC considers this a serious public health concern, based on current information, the immediate health risk from 2019-nCoV to the general American public is considered low at this time. Nevertheless, CDC is taking proactive preparedness precautions.
This is a rapidly evolving situation and information will be updated as it becomes available.
