The coronavirus outbreak is causing travel demand across the whole Asia Pacific region to slump, data showed on Thursday, as the impact of the flu-like illness on future bookings spreads beyond China.

ForwardKeys, a travel analytics company, said that airline bookings from across the region were 10.5% lower for March and April 2020 compared with last year. That drop excludes trips to and from China and Hong Kong.

Deaths from the virus rose to 1,350 on Thursday and airlines are bracing for lower ticket sales as worries over the virus’s spread hit appetite for travel and caused conferences and events to be scrapped.
