We know that viral outbreaks have affected the stock markets before now, it's likely that a continued rise in the coronavirus and as it spreads further around the world, we'll likely see stocks take a hit from it again.
It's not unreasonable therefor to imagine that the price of BTC could be negatively impacted. I think it's because, when crisis's like this hit, people are often left with costly medical bills or unplanned expenses travelling to see friends / family, as they start to withdraw from investments and that has a bit of a negative trickle on the economy, more and more people start selling them.
Maybe it wont, ultimately who knows? I could be wrong and I think a lot of it is going to depend on how bad this situation gets. If it does just fizzle out then we may get through this pretty much unscathed.
