That would mean roughly 3-4 million deaths in the United States.
The OP estimates 200,000 deaths
Yeah, somebody's math isn't quite right - probably the doctor's given they went to medical school and aren't accountants.
1 in 10,000 dead would be significanly less lethal than the average seasonal flu, which kills anywhere from 35K to 50K each year, in the US alone. Of course, the difference is virtually all the deaths from seasonal flu come from much older and ailing people that have already compromised immune systems.
If this new strains starts to kill people who are actively engaged in the workforce, and it's distributed across the country, that's where some complexions will come from.
