General Cluster Information

Low morbidity jurisdiction?

Person Completing Report:

Email address:

1. Date cluster first detected    

2. Date form completed 

3. Local Cluster ID entered into eHARS   
A local cluster ID must be populated on this form and in eHARS.
For molecular clusters, the recommended nomenclature is the two-letter jurisdiction
abbreviation followed by the year and month in which the cluster was first identified
and Secure HIV TRACE cluster ID (e.g., GA_YYYYMM_10-5)
For time-space clusters, the recommended nomenclature is the two letter jurisdiction
abbreviation followed by the year and month in which the cluster was first identified
and cluster ID with the initials ‘TS’ (e.g., GA_YYYYMM_TS789). Jurisdictions may use any
naming convention to develop the cluster ID as long as it includes the initials ‘TS’ and
does not contain personal identifiers.

4. National Cluster ID (if applicable)  

5. Initial cluster detection method that identified this cluster (please select one; if 'other' is selected, use the box to the right to
describe):
For clusters identified by time-space analysis, please enter the county or other geographic area of the alert.

5a County of time-space alert
5b Other geographic area of alert
6. For clusters identified through molecular analysis, does this cluster meet national priority cluster criteria? (for cluster defined at 0.5% genetic distance threshold ≥5
diagnoses in past 12 months, or ≥3 diagnoses in past 12 months for low-morbidity jurisdictions) 

7. Had this cluster been identified by any other method?

7a. If the cluster overlaps with another cluster identified by a different method, please
select the method of identification, date of detection and cluster ID

12. Number of people with HIV in the molecular cluster at time of detection who have a report of HIV in your jurisdiction:
13. If additional people with HIV with a report of HIV in your jurisdiction have been added to the molecular cluster (based on any
subsequent data analysis) since first identification, enter current numbers:

Other (specify):
Non-Molecular Clusters. Complete this section only for clusters detected through other methods (i.e. time-space analysis or provider notification).

9. Please describe the characteristics of the cluster that have raised concern (e.g. an increase in diagnoses over a baseline, an
increase in IDU-associated HIV-infections, etc.). 
9b. Please describe the case definition you are using to determine which cases are included in this cluster (i.e., inclusion criteria for
person, place, and time).
10. What is your current level of concern for this cluster?
(Note: Select 'High' if additional response is needed, 'Medium' if additional information about the cluster is needed, or 'Low' if no additional investigation activities are needed at this time. It is not necessary to
report clusters of low priority to the CDC unless the cluster meets national priority cluster criteria, or if enhanced response activities have been initiated)
11. Please briefly describe data review and investigation/response activities conducted to date for this cluster, and any notable
findings.

13. If additional people with HIV with a report of HIV in your jurisdiction have been added to the molecular cluster (based on any
subsequent data analysis) since first identification, enter current numbers: 
14. At what genetic distance threshold(s) is this cluster defined?  (If 'other' is selected, use the box to the right to describe)

Public reporting burden of this collection of information is estimated to average 60 minutes per response, including the time for
reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing
the collection of information. An agency may not conduct or sponsor, and a person is not required to respond to a collection of
information unless it displays a currently valid OMB control number. Send comments regarding this burden estimate or any other aspect
of this collection of information, including suggestions for reducing this burden to CDC/ATSDR Information Collection Review Office,
