Using syndromic surveillance systems to detect pneumonic plague

Area of Science:

• Public Health
• Epidemiology
• Infectious Disease Surveillance

Background:

• Syndromic surveillance systems rely on pre-diagnostic data for early disease outbreak detection.
• Understanding the initial presentation of diseases is vital for effective surveillance.
• Pneumonic plague, a zoonotic disease, poses a significant public health threat.

Purpose of the Study:

• To determine the earliest signs and symptoms of pneumonic plague for syndromic surveillance.
• To inform the design of effective syndromic surveillance queries for pneumonic plague.
• To explore the utility of integrating animal data into human disease surveillance systems.

Main Methods:

• Review of medical literature on the sequence of signs and symptoms of pneumonic plague.
• Analysis of early-stage patient presentations, focusing on gastrointestinal and respiratory indicators.
• Examination of zoonotic disease surveillance strategies, including animal data integration.

Main Results:

• Early pneumonic plague patients predominantly exhibit gastrointestinal symptoms with minimal respiratory signs.
• Failure to recognize these early gastrointestinal signs can delay detection in syndromic surveillance.
• Animal data from sources like park rangers and veterinarians may offer valuable early evidence.

Conclusions:

• Syndromic surveillance systems must account for the earliest, often non-respiratory, symptoms of pneumonic plague.
• Integrating human and animal health data can enhance the early detection of zoonotic diseases like plague.
• Literature reviews are essential for designing targeted and effective syndromic surveillance queries.
