Summary
This study developed a machine learning model to detect COVID-19 using only self-reported symptoms. Promising results show potential for inexpensive, scalable diagnostic tools, especially in resource-limited settings.
Area of Science:
- Infectious Diseases
- Machine Learning
- Public Health
Background:
- The COVID-19 pandemic caused by SARS-CoV-2 necessitated widespread public health measures, including lockdowns.
- Developing nations face challenges in accessing essential diagnostic resources for COVID-19.
- There is a need for accessible and scalable methods for COVID-19 detection.
Purpose of the Study:
- To develop and evaluate a machine learning approach for detecting COVID-19 infections based solely on self-reported symptoms.
- To assess the feasibility of an inexpensive and easily deployable diagnostic tool for COVID-19.
- To provide a potential solution for COVID-19 screening in resource-limited areas.
Main Methods:
- A machine learning model was trained using self-reported symptom data.
- The model's performance was evaluated using sensitivity, specificity, and ROC AUC metrics.
- The approach focused on symptom-based detection without requiring laboratory diagnostics.
Main Results:
- The best-performing model achieved a sensitivity of 0.752 and a specificity of 0.609.
- The receiver operating characteristic (ROC) curve area under the curve (AUC) was 0.728.
- These results indicate a promising performance for a symptom-based detection method.
Conclusions:
- Symptom-based machine learning models show potential for COVID-19 detection.
- This approach offers a cost-effective and scalable alternative or supplement to traditional diagnostics.
- Further research is warranted to refine these models for widespread application in COVID-19 screening.
