In recent weeks, a novel coronavirus (2019-nCoV) was detected in Wuhan City, China, and the virus has spread to a growing number of countries, including the United States. The U.S. Centers for Disease Control and Prevention (CDC) is taking aggressive public health measures to help protect the health of Americans, including requesting that the CDC Foundation activate its Emergency Response Fund to provide support to rapidly emerging response needs. The CDC Foundation today announced a catalytic donation of $1 million from the Robert Wood Johnson Foundation in support of this fund.
