Standardization of Epidemiological Surveillance of Acute Rheumatic Fever

Area of Science:

• Rheumatology
• Infectious Diseases
• Public Health Surveillance

Background:

• Acute rheumatic fever (ARF) is an autoimmune inflammatory condition triggered by Streptococcus pyogenes (Strep A) infections.
• ARF disproportionately affects low- and middle-income countries and indigenous populations, often linked to undetected Strep A.
• A single ARF episode elevates the risk of developing rheumatic heart disease, a significant cause of long-term cardiac damage.

Purpose of the Study:

• To present updated case definitions for definite and possible ARF, including initial and recurrent episodes, based on the 2015 Jones Criteria.
• To review current diagnostic tests and outline surveillance methodologies for ARF.
• To discuss critical aspects of ARF surveillance, including secondary prophylaxis, follow-up, registers, community engagement, and ethical considerations.

Main Methods:

• Utilized the 2015 Jones Criteria for case definitions of Acute Rheumatic Fever (ARF).
• Reviewed existing diagnostic tests to support ARF diagnosis.
• Described various surveillance strategies, including active and passive methods, in diverse settings like schools and healthcare facilities.

Main Results:

• Established clear case definitions for ARF, differentiating between definite and possible cases, and initial versus recurrent episodes.
• Highlighted the importance of timely diagnosis and surveillance for preventing rheumatic heart disease.
• Provided a comprehensive framework for ARF surveillance, encompassing methodology, participant selection, and data collection.

Conclusions:

• Accurate case definitions and robust surveillance are essential for controlling ARF and preventing rheumatic heart disease.
• Effective ARF surveillance requires tailored methodologies, community engagement, and ethical considerations.
• The presented guidelines aid in standardizing ARF diagnosis and monitoring, particularly in high-risk populations.
