BBC News – Coronavirus: Should Americans be worried?

The president’s political rivals have also renewed criticisms over his 2018 decision to dismantle the National Security Council global health unit. The CDC’s global health division also saw drastic cuts that year.

What are the main concerns?

High medical costs make the virus particularly problematic – many Americans avoid doctor’s visits because of unaffordable charges.

Last month, a Florida man with symptoms had a coronavirus test and was handed a $3,270 bill from his insurance company.

Taking sick leave is another concern. Not all employers offer paid leave and workplace culture often pushes employees to go to work ill.

This is from May 2018.  Probably not a big deal, back then.
