The COVID-19 outbreak that began in China has sickened 2 million worldwide.
By Monday, the novel coronavirus outbreak in the United States had grown to more than 577,000 cases in all 50 states, the District of Columbia and Puerto Rico. There are outbreak clusters in New York, Washington state and California, according to Johns Hopkins University, which is tracking reports and confirming them with local health departments.
The number of cases in the U.S. and worldwide is the subject of some debate, as testing has been rolled out unevenly and the criteria for diagnosis (through clinical means or a lab test) has varied from country-to-country.
