I have a lengthy trip to China coming up in a couple of months. Not really worried about the virus, but if more cities are locked down and tourist sites closed it will affect our holiday plans. Our booked visit to the panda breeding centre in Chengdu is already looking unlikely.
For now we'll just watch and let events unfold, but if things get significantly worse we'll have to hope that the government issues a travel advisory and/or that BA will start allowing passengers to cancel and/or rebook to other destinations.
