US stocks continued their sharp two-day sell-off on Tuesday as the CDC told Americans to brace for a possible coronavirus outbreak.

The Dow Jones industrial average has now fallen more than 1,910 points over two days.

The torrid decline adds to a more than 1,000-point sell-off in the Dow Jones industrial average on Monday, which erased the index's losses for the year.

The S&P 500 also entered the session fresh off its worst day since February 2018.

The biggest declines on Tuesday were absorbed by airlines, air freight and logistics, and consumer finance stocks.
