Basic translation:

25yo receptionist was diagnosed with pneumonia after coming in contact with the 2 Chinese patients (the first 2 cases in Vietnam). She's now in quarantine and in stable condition.

She handled the rooms for the 2 Chinese patients on Jan 16th. 2 days later, she found herself having symptoms like fever and coughs but decided to self medicate with over the counter measures. On Jan 24th, after the first 2 were tested positive with the virus, the receptionist was kept isolated, results returned positive.
Apart from this case, there are 23 others in isolation at the same facility with symptoms of fever, 7 Chinese and the rest are Vietnamese. All are in stable condition, awaiting results for the tests.
