One option is to fly out via Cebu - there should be flights from Tacloban and international flights from Cebu!
They are also allowing a certain number of international flights from Manila over the next 72h - that would be your second option...
While Manila has world-class hospitals & care and the number of reported is low, cases are likely under-reported due to lack of testing and the healthcare system is not equipped to handle an escalation of the situation. I'd recommend to leave while you can...
Unfortunately, even Cebu is also on lockdown, so I can't go to Manila nor Cebu if domestic flights are currently suspended. I have no choice but to wait until April.
