I suspect a few expats might well be concerned at the possibility of coronavirus spreading in Indonesia, but the chances of a major problem are pretty slim.
A number of Indonesian expats are stuck over there at the moment, and the suspected local cases so far have not been confirmed, or dismissed as common flu after testing.
Airports are screening arrivals and hospitals are taking possible cases very seriously, assuming it is the virus until proven otherwise, exactly the right thing to do.
Note - Watch out for ridiculous hoax stories put out for political reasons - A few are already doing the rounds, even one in a US comic pretending to be a newspaper.
In other words, so far at least, there's little to worry about unless you're a hotel owner with lots of cancelled bookings due to the lockdown in China.
