Symptoma

Symptoma provides differential diagnoses by analyzing user-reported symptoms with artificial intelligence to identify and rank possible diseases, including COVID-19.

Key Features:

• Extensive Disease Database: Differentiates among more than 20,000 diseases with reported accuracy exceeding 90%.
• High COVID-19 Identification Accuracy: Accurately distinguished COVID-19 in 96.32% of evaluated instances and identified all infected individuals when presented with three characteristic signs using symptoms and risk factors alone.
• AI-based Diagnostic Algorithm: Uses an artificial intelligence algorithm to analyze symptoms against its disease database and generate probability-ranked diagnoses.
• Free-text Input and Disease-specific Follow-up Questions: Collects symptom data via free-text input and refines responses using targeted follow-up questions for specific diseases.
• Superior to Simple Questionnaires: Demonstrates higher diagnostic accuracy compared with basic yes-no symptom questionnaires.
• Multilingual Support: Operates in 36 languages.

Scientific Applications:

• Prescreening: Serves as a prescreening mechanism to reduce burden on telephone hotlines during epidemics and high call volumes.
• Clinical Decision Support: Provides differential diagnoses to assist healthcare professionals in prioritizing and making clinical decisions.
• Public Health Surveillance: Supports identification of COVID-19 cases for use in monitoring and controlling infectious disease spread.

Methodology:

Symptoma employs an artificial intelligence-based algorithm that analyzes entered symptoms against its extensive disease database and outputs a probability-ranked list of potential diagnoses; it collects symptom data via free-text input and applies disease-specific follow-up questions to refine the diagnostic ranking.
