# Medical Symptom Checker

An interactive medical symptom checker that helps users explore symptoms and related diseases using vector similarity search and a database of medical conditions.

## Features

- Enter symptoms to find related diseases
- See semantically similar symptoms through vector search
- Discover related symptoms from matching diseases
- Interactive UI for refining symptom selection

## How It Works

1. **Vector Search**: Uses Sentence Transformers and ChromaDB to find semantically similar symptoms
2. **Database Matching**: Finds diseases that match all selected symptoms
3. **Related Symptoms**: Shows other symptoms from matching diseases

## Usage

Enter a symptom in the search box (e.g., "fever", "cough", "headache") and click "Search" or press Enter.

The system will:
1. Show diseases that have that symptom
2. Display semantically similar symptoms
3. Show other symptoms from the matching diseases

Click on any symptom in the "Similar Symptoms" or "Related Symptoms" sections to add it to your selection. This will narrow down the diseases to those that have ALL selected symptoms.

## Technical Details

- **Frontend**: HTML, CSS, JavaScript
- **Backend**: FastAPI, SQLite
- **Vector Search**: Sentence Transformers, ChromaDB
- **Data**: Diseases and symptoms dataset

## Deployment
