TOKYO (Reuters) - Oil prices fell for a fifth day on Thursday to their lowest since January 2019 as a growing number of new coronavirus cases outside of China fuelled fears of a pandemic which could slow the global economy and lower crude demand.
Brent crude (LCOc1) was down 63 cents, or 1.2%, at $52.80 a barrel at 0414 GMT. The contract earlier fell to as low as $52.57, the lowest since Jan. 2, 2019.
West Texas Intermediate (WTI) futures (CLc1) fell by 65 cents, or 1.3%, to $48.08 a barrel. It earlier fell to as low as $47.84, the lowest since Jan. 4, 2019.
In the five trading sessions through Thursday, Brent has dropped 11%, while WTI has declined 10.6%, their biggest five-day percentage losses since August 2019.
On Wednesday, for the first time ever, the number of new coronavirus infections outside China, the source of the outbreak, exceeded the number of new Chinese cases.

On Wednesday, consultants Facts Global Energy forecast oil demand growth will only 60,000 barrels per day in 2020, or "practically zero", because of the widening outbreak.
U.S. President Donald Trump assured Americans on Wednesday evening that the risk from coronavirus remained "very low".

"Speculations that coronavirus may spread in the United States prompted a series of fresh selling," said Kazuhiko Saito, chief analyst at Fujitomi Co.
If an outbreak "continues to worsen in the United States, oil prices will likely decline further, especially with U.S. gasoline prices already plunging," Saito said.
The United States is the world's largest oil producer and consumer.
