At least 12 US states have declared states of emergency so far over the coronavirus outbreak as global cases exceed 110,000.

On February 29, the US reported the first death from the novel coronavirus in the country, in Washington state.

On March 2, the governor of Washington state declared a state of emergency. In total, 23 people have died from the virus statewide.

The current death toll nationwide is 28 and more than 800 people are infected across the US.

Since then, California, Maryland, Utah, Kentucky, New York, Oregon, Florida and New Jersey have all declared states of emergency.

Two deaths each have been reported from the virus in California and Florida while New Jersey has reported one death.

The latest states to declare emergencies are North Carolina, Colorado and Massachusetts.

North Carolina Gov. Roy Cooper said the decision came after a meeting with health experts, business leaders and emergency management in the state and other states.

"The new cases and the advice of these experts have led us to give new guidance to North Carolina residents and to declare a state of emergency for our state," Cooper said at a press conference Tuesday.

The coronavirus, officially known also COVID-19, was first detected last December in Wuhan, China.

The global death toll from the coronavirus is now over 4,260, with more than 118,100 confirmed cases, according to Johns Hopkins University.

The virus has since spread to six continents and more than 100 countries.
