| Characteristic | No. of molecular clusters identified in Wisconsin | No. of molecular clusters identified in NHSS |
|---|---|---|
| No. of persons included in analysis |
1,401 |
40,950 |
| No. of persons with ≥1 molecular linkage |

* A molecular cluster describes a set of ≥2 linked sequences in which each sequence is connected, either directly or indirectly, to all other sequences.
† Analysis included HIV-1 genetic sequences reported through August 15, 2017, to the Wisconsin Division of Public Health for persons with HIV infection diagnosed during 2014–2017.
