The famously busy streets of New York City have been much emptier than usual as a state of emergency takes effect.

More than 400 infections have been reported in the state, prompting authorities to open a drive-through mobile testing centre.

It is operating in New Rochelle, about 25 miles (40km) from New York City, where a containment zone is in place.
