COVID-19 moving toward a pandemic
The virus has been named SARS-CoV-2, and the disease it causes has been named COVID-19. The virus was first detected in Wuhan City, China, and has now been identified in 32 countries, including the U.S.
The Centers for Disease Control and Prevention (CDC) says the potential public health threat posed by COVID-19 is high globally and across the U.S.
"Large numbers of cases are now beginning to occur in South Korea. How and whether it spreads from there, as well as in Western Europe, will be determinative in understanding how far and easily this virus will spread worldwide," says Dr. Poland.
A pandemic refers to a global epidemic — one that has spread over several countries or continents affecting a large number of people.
