What are the most commonly experienced symptoms, causes, and treatments?

Flu

A person who needs a flu checkup has aches, pain, fever, fatigue, and other symptoms of the flu, an infection caused by a virus that attacks the lungs, nose, and throat. The flu is caused when you inhale bodily fluids from an infected person who coughs, sneezes, or propels the virus into the air. The flu can be mild to severe to life-threatening, but most cases can be treated at home with over-the-counter medication and lots of fluids and rest.

Common Causes: Viral germs acquired from an object or when they travel via air droplets after someone coughs, sneezes, or talks.

Common Treatment(s): Prescription Antiviral Medication, Cold Medicine, Bed Rest, Fluids.

How Does Symptom Checker Work?

Everyday Health’s Symptom Checker is a certified (CE marked class 1) preliminary diagnosis and triage tool powered by Infermedica that leverages artificial intelligence, data science experts, and physicians to assess more than 1,500 symptoms and 800 conditions.

All content featured in the tool is created through a rigorous content development process. Infermedica’s team of data scientists and medical professionals, led by Chief Medical Officer Irv Loh, MD, regularly analyzes statistical information collected by the tool to identify content areas that need to be expanded.

Medical content editors create the new content, adding an original source to each piece of new medical information. The content is then peer-reviewed by another medical content editor to validate all sources and identify potential areas for improvement.

After the content is peer-reviewed, Infermedica’s doctors identify literature-based clinical cases from sources such as The BMJThe New England Journal of MedicineThe American Journal of MedicineMayo Clinic Proceedings, BioMed Central, and Oxford journals to create clinical test cases.

The clinical test cases are then added to the medical database and validated against a diagnostic engine. A specialist verifies the newly created content and a data scientist identifies and corrects potential issues, such as duplicate symptoms.

The new conditions and symptoms content undergo regression testing to ensure the stability of the tool and are also manually tested by a team of doctors. The content is then published to the cloud-based API and made available to all users of Infermedica products.
