Pre-encounter symptom intelligence

Before outbreaks become official data, they become human symptoms.

SymptomSignal helps people report symptoms in any language by voice or text — then turns those reports into privacy-preserving early signals for public-health teams.

  • Private by design
  • All-language intake
  • Built for public health
  • Not a diagnostic tool
  • Human-reviewed alerts

One platform

Two urgent needs.

For people

Explain what you feel, in your own language.

Speak or type symptoms naturally. SymptomSignal asks a few clarifying questions, checks for warning signs, helps you track symptoms over time, and creates a doctor-ready summary when needed.

  • Voice or text symptom reporting
  • Daily symptom journal
  • Red-flag safety guidance
  • Doctor-ready summary export
  • Private by default
For public health

See the signal before the surge.

Aggregated symptom reports become privacy-preserving community signals, helping public-health professionals identify unusual patterns, monitor clusters, and decide what deserves investigation.

  • Privacy-safe heat maps
  • Composite signal scoring
  • Epidemiologist Workbench
  • Data quality labels
  • Lead-time and false-alarm tracking
How it works

From one symptom story to an early public-health signal.

01
People report symptoms
A person speaks or types what they are experiencing in their own language.
02
AI clarifies safely
AI asks only the questions needed: when symptoms started, severity, exposure, test results, and urgent warning signs.
03
Reports become structured signals
Symptoms are normalized into privacy-safe syndrome patterns such as respiratory illness, GI illness, fever+rash, or unknown clusters.
04
Public health sees what may be emerging
Aggregated signals appear in an Epidemiologist Workbench with confidence, data quality, geography, trend, and review status.
For people

Designed for a sick person, not a spreadsheet.

When someone feels unwell, the experience must be simple, calm, and useful in under 90 seconds.

For public health

Built for the questions public-health teams actually ask.

Is something unusual happening? Where? Since when? Compared to what baseline? How confident are we? What should we do next?

Investigation Summary

User-reported fever, cough, fatigue, and sore throat increased above baseline. Onset dates cluster within 72 hours.

Recommended next step: compare with ED, wastewater, lab, and school absenteeism data.

Privacy

Privacy is not a feature. It is the foundation.

Private by default

Users can keep symptom journals private and choose whether to contribute anonymously.

No exact public location

Public maps show only aggregated, privacy-safe regions. Individual reports are never displayed.

No diagnosis claims

SymptomSignal identifies symptom patterns and warning signs. It does not diagnose or replace clinicians.

Human-reviewed public-health alerts

AI can detect and summarize signals, but high-impact public-health actions require authorized human review.

Layered consent
Multilingual

Illness does not speak one language. Neither should public health.

SymptomSignal supports all-language intake from day one, with validated language quality expanding over time.

The platform accepts symptom reports in any Unicode language, detects language automatically, supports right-to-left layouts, and translates reports into structured symptom concepts. High-volume languages can be validated with reviewed symptom vocabulary, safety phrasing, and public-health messaging.

Use cases

Where early signals matter.

Schools and childcare

Track privacy-safe respiratory, fever+rash, and GI symptom patterns across classrooms or cohorts.

Cities and counties

Add community-reported symptom intelligence to public-health monitoring workflows.

Universities

Detect symptom clusters across campus before clinics and labs show a surge.

Events and conferences

Monitor post-event illness signals using anonymous QR-code reporting.

Senior living

Support early awareness of respiratory and GI illness patterns in high-risk settings.

Global health and NGOs

Enable multilingual symptom reporting in communities with limited formal healthcare access.

Signal fusion

Stronger signals come from multiple layers.

Composite Public Health Signal
Confidence-weighted, human-reviewed.

A symptom spike alone may be noise. A symptom spike with tight onset timing, geographic clustering, rising absenteeism, and external corroboration becomes a stronger signal.

Pilots

Start with a focused pilot. Prove the signal.

Respiratory illness pilot

Monitor fever, cough, sore throat, fatigue, and test results across a defined community.

School GI cluster pilot

Track vomiting and diarrhea signals with privacy thresholds and school nurse review.

Event watch pilot

Use QR-code reporting before and after large gatherings to detect emerging symptom patterns.

SymptomSignal does
  • Help people describe and track symptoms
  • Screen for urgent warning signs
  • Identify possible symptom patterns
  • Generate privacy-preserving community signals
  • Support public-health review workflows
SymptomSignal does not
  • Diagnose disease
  • Replace a clinician
  • Declare official outbreaks
  • Provide definitive disease probabilities
  • Sell symptom data
  • Display exact personal location publicly

Build earlier awareness before the next surge.

SymptomSignal helps communities share what they are feeling — safely, privately, and in their own language — so public-health teams can see what may be emerging sooner.

FAQ

Questions, answered plainly.

No. SymptomSignal helps people describe and track symptoms and screens for urgent warning signs. It does not diagnose disease and is not a substitute for medical care.
