Market Summary

Coronavirus disease (COVID-19) is an infectious disease caused by a new virus. COVID-19 can cause respiratory illness with symptoms including cough, fever, and difficulty breathing. Currently, there are no approved treatments or vaccines for COVID-19 and it is the center of the current pandemic. Because COVID-19 is a highly contagious disease, measures are in place to reduce the number of times people come into close contact with each other. There is a need to help people exhibiting COVID-19 symptoms know whether they need to travel to see a medical professional in-person.

Technical Summary

The C19Checker severity stratification tool allows for the mass screening of individuals exhibiting COVID-19-like symptoms in a non-hospital setting. The screen builds on the previous SORT algorithm developed at Emory, which relies on the CDC-developed CRB-65 risk stratification tool, a well-validated technique that includes assessment of the severity and potential risk of death due to a community acquired illness as well as a brief review of factors related to co-morbidity. The risk assessment screening tool developed at Emory University can be administered online and allows for effective screening of large numbers of individuals, while alleviating the surge of visits to a hospital or doctors’ office and lessening interactions with infected individuals within these settings. The content has also been adapted for use with a mobile SMS/USSD platform.
