Well if you can move it to another part of the year (like October) --- my friend and I decided to move our flight (after a lovely 7.5 hour on hold with Lufthansa)--- anyways. We lost a small amount of money, mainly because the first hotel we booked was non-refundable (so $277 each but not bad for a huge expensive trip). Most plane carriers are being more forgiving now with the virus situation.
I think a bigger concern than getting sick is going somewhere then the country decides to shut down everything you planned on visiting. This was our primary issue. It is entirely unpredictable what the government will do - will they close museums, can you get food if restaurants are now all shut down, and grocery stores out of stock and you have no kitchen to cook in? Those are much larger concerns. If you can't eat anywhere good, and you can't visit the things you want to see, you'll just be hungry and annoyed. True you can go on a nice hike in those places, but you won't want to if you are starving. And being stuck in a hotel is not that fun.
I was quarantined in China in 2009 for the whole swine flu pandemic. 2 weeks in a hotel with 3 tv stations is torture. If you can reconsider or get your money back really try----
