I don't think this has been reported in the local media yet. Apparently some SARS like respiratory illness is going around.
Some sources report that the disease has been known since November 2019, with restrictions on flights coming in and out of Wuhan being screened for quite some time now.
Anyone thinking of cancelling their CNY trips?
We were there in May, no problems. We got some chest bug on a plane which put a damper on things but got some local antibiotics to get us through the trip. Keep your immune system strong and take the right supps with you.
