If he answers in the affirmative, he pisses off China, and will likely see them retaliate by withdrawing from cooperation at a time when that could have severe impacts on the world's ability to deal with a pandemic.
If he answers in the negative, he pisses off Taiwan, a lot of people, and a lot of countries who are also not willing to stand up to China on this issue.
And what's the benefit for asking this of an epidemiologist. He's not there to give personal political opinions, he's there to be an expert on a specific subject.
As for the rest of the issues - I know you're not specifically saying it, but there's a lot of folks that blame the WHO for not warning people about this, or delaying announcements.
The WHO were quite early in warning that countries should be prepared for this, that there should be greater efforts put in attempting to limit it's spread.
There is some truth that they didn't declare it a pandemic as early as everyone wanted, they had to wait for it to meet official definitions of being a pandemic.
The WHO declaring a pandemic, however, didn't mean countries couldn't act earlier to stop it.
