In the first outbreak (July-August), 49 people were investigated, 25/49 (51.0%) cases, 10/25 (40.0%) staff, 15/25 (60.0%) patients, 8/25 (33.3%) medical clinic, 16/25 medical (66.7%) medical clinic and 21/25 (84.0%) symptomatic. Among the cases in patients, 15/11 (73.3%) had onset of symptoms after 7 days of hospitalization. Use the 5W2H matrix as an action plan. After the execution of the actions, there were active cases for 7-10 days. The patient was presented at the same time 35 days, the most critical moment occurred after 17 days of the symptom, there were 15 patients active at the same time and the R was 2.92. In the second outbreak (September-October), 127 people were investigated and there were 6/127, of these 2/6 (33.3%) staff, 4/6 (66.6%) patients, 4/6 (66.6% ) ) medical clinic, 2/3 (33.3%) clinic 6, 4/6 (4/6) symptomatic.
