The first U.S. case of the potentially deadly COVID-19 virus was confirmed in Washington state in January. Since then, additional cases have been confirmed in at least 21 states. Washington, California and New York have since reported dozens of confirmed cases, while most other states have seen infections registering in just the single digits.
Department of Health and Human Services Secretary Alex Azar declared a public health emergency for the U.S. on Jan. 31 and, as the number of cases rises, states are following suit, taking precautionary measures ahead of feared local outbreaks.
