Case Surveillance and Contact Tracing Efforts Across Jurisdictions HAN alert (NYC: AIDS Institute, Inter- City ID Rounds, NYS DOH, NJ DOH, CDC, PR TB Control, NTCA) Watch list of all HIV-infected contacts (NYC TB surveillance, NYS DOH, NJ DOH) Continue monthly registry checks (NYC prison, DHS/HASA, TB registry, NYC death registry) –Found 1 d/c resident found through NYC death registry match Cause of death: metastatic esophoegeal cancer 11/05 NYS prison search –Found 2 more d/c residents Both fully evaluated and on TLTBI with MXF

Summary Extensive transmission Rapid progression to disease Active case finding identified one additional MDR TB case Home visits and contact with providers proved effective Registry match with HIV surveillance was useful Shared genotyping and outbreak information with other jurisdictions vital

Lessons Learned Case finding activities should be initiated in settings for HIV-infected individuals where TB transmission is evident Alerts to neighboring jurisdictions should occur earlier –Confidentiality and privacy issues Expansion to other jurisdictions for contact tracing extremely useful –Routine information sharing around outbreaks Partnering with other DOHMH Bureaus (HIV, Correctional Health) very helpful
