Searches for bookings during the April 4-6 Tomb Sweeping Holiday, or Qing Ming Festival, jumped 138 percent on Feb 23 from a week earlier, while those for flights in the Labor Day break from May 1 to 5 increased 84 percent, the Hong Kong-listed company said in a statement Friday.

Coronavirus cases continue to spread further afield, with Nigeria confirming the first reported infection in sub-Saharan Africa on Thursday. The number of cases in South Korea has crossed 2,000, while infections have cropped up in countries from New Zealand to Lithuania.
