Delay to First Diagnosis, Number of Cumulative Cases at First Diagnosis, and Number of Tests Conducted to Diagnose a First Case, by Testing Strategy, in the Context of a Simulation of a SARS-CoV-2 Outbreak in a LTCF

Testing Strategy∗	Delay to First Diagnosis, Mean d (Median, IQR)	Cumulative Cases at First Diagnosis, Mean (Median, IQR)	Number of Tests Conducted, Mean
1. Test 100% every 14 d	7.9 (7.0, 8.0)	13.3 (5.0, 9.0)	218
2. Test 50% every 7 d	6.6 (6.0, 6.0)	7.3 (4.0, 5.0)	192
3. Test 100% every 7 d	4.0 (3.5, 4.0)	3.8 (2.0, 3.0)	278
4. Test 50% twice a wk	3.5 (3.0, 4.0)	3.2 (2.0, 3.0)	260
5. Test 20% on weekdays	3.3 (3.0, 4.0)	2.8 (2.0, 3.0)	251
6. Test 14% daily	3.3 (3.0, 4.0)	2.7 (2.0, 2.0)	252
7. Test 100% twice a wk	1.7 (1.0, 1.0)	1.8 (1.0, 1.0)	372

^∗All individuals are susceptible at baseline, 1 infectious case is imported randomly in the first 2 weeks of simulation, and the model tracks individual disease status daily until a first case is diagnosed. Results for 1000 iterations.
