Hong Kong's Disneyland announced it was shutting its doors on Sunday until further notice over the deadly virus outbreak in central China, a day after city authorities classified the crisis as an emergency.
The park said it was taking the step to protect "the health and safety of our guests and cast members", mirroring a similar move by Shanghai's Disneyland.
Ocean Park, a rival amusement park on Hong Kong's main island, said it was also closing its doors.
On Saturday, Hong Kong classified the outbreak as an "emergency" -- the city's highest warning tier -- and announced ramped-up measures to reduce the risk of further infections.
The move came as city leader Carrie Lam faced criticism in some quarters over her administration's response to the crisis.
Calls have been made by politicians and some medical experts to halt, or limit, arrivals from the Chinese mainland where the epidemic began.

The closure of Disneyland and Ocean Park will pile fresh misery on Hong Kong's tourism, leisure and retail sectors which have already been battered by more than seven months of often-violent pro-democracy protests.
Ocean Park is on track to receive a HK dollar 10.6 billion (USD 1.3 billion) government bailout over grim ticket sales in recent years.
Combined with the US-China trade war fallout, the protests have helped tip Hong Kong into recession and the virus outbreak has only compounded the city's economic woes. Lam's approval ratings are languishing at record lows after the protests but Beijing has doggedly stuck by her.
