You can see flights currently arriving/departing Male on the airport site mentioned above, but there's nothing today that looks helpful.
Washington has been saying they'll help Americans stranded overseas, but obviously there are limits on that help. Are there enough Americans in the Maldives to merit sending a plane? Apparently the US "embassy" in the Maldives is actually located in Colombo. No harm in getting on some contact list there in case a flight out is arranged.
But nothing's going to happen very quickly. (Unlike Wuhan, folks stranded in Male probably aren't at great health risk at the moment, just really inconvenienced.)
