Resources for STD Case Notification

Syphilis Surveillance Tools

Syphilis is an STI that follows a progression of stages. However, identifying the stage of syphilis in adults can be challenging. See the following resources for guidance on staging syphilis in adults for surveillance purposes.

The Council of State and Territorial Epidemiologists (CSTE) Syphilis Case Definition provides clinical, laboratory, and epidemiological criteria used to stage syphilis.

See the CSTE Syphilis Case Definition

 

CDC’s Adult Syphilis Staging Algorithms provide additional guidance on staging syphilis in adults who may or may not have signs or symptoms. The staging algorithms do not supersede the CSTE syphilis case definition.

The CSTE syphilis case definition and CDC’s staging algorithm should not be used for determining staging for clinical care. For more information on clinical staging and treatment recommendations for syphilis, see CDC’s STI Treatment Guidelines.

The Council of State and Territorial Epidemiologists (CSTE) offers a free “Case-based Surveillance for Syphilis” course. The course is divided into multiple lessons and discusses both adult and congenital syphilis surveillance.

Automated Record Search and Review Algorithm for Syphilis

Public health agencies prioritize investigations of syphilis cases using:

  • Lab results (i.e., nontreponemal test titer)
  • Age and sex at birth
  • Prior syphilis history

However, these traditional methods miss potential cases. They also require many resources. CDC with the Florida Department of Health and New York City Department of Health and Mental Hygiene developed a new algorithm for prioritizing case investigations. The new algorithm automates the traditional process.

Reporting Guidance for the National Electronic Telecommunication System for Surveillance and the National Electronic Disease Surveillance System

The National Electronic Telecommunication System for Surveillance (NETSS) and the National Electronic Disease Surveillance System (NEDSS) are data transfer and information technology architectural standards. NETSS and NEDSS are used by public health agencies to report STD surveillance information including:

  • Numbers of new STDs
  • Results from laboratory tests
  • Information on STD treatment
