I would wait until June to make a decision and try to travel this year. Everything is going to be empty and you will enjoy it more.
My sister works in tourism in Peru and she tells me that a lot of people are re-scheduling for next year in the same months they are cancelling now. So, on one hand, there are a lot of bookings for next year, and a lot of space this year. And in the other, I am sure that next year when a Chinese person sneezes, most countries will re-impose security measures because of the social fear brought by what is happening now, and that might disrupt your plans next year.
