The C.A.T.C.H. Study has morphed into the StopCOVID Study

After three and a half years, the CATCH study is drawing to a close. We’ve worked with hundreds of participants and collected thousands of specimens, and we’ve improved our understanding of the transmission of respiratory viruses. We even had an article published recently: “Ventilation and laboratory confirmed acute respiratory infection (ARI) rates in college residence halls in College Park, Maryland” – Environment International 137 (2020) 105537, Zhu et al.

This program known as CATCH is ending, but there’s still quite a bit more work to be done! Go to our new study StopCOVID UMD at to find out more!


The CATCH study team

CATCH Year 4 is live!!!

Although our study is slightly different this year, our goal is still to figure out what makes people contagious, so we can prevent the spread of disease. With an improved understanding of what contributes to and impacts contagiousness, we may better prepare for – and possibly prevent – future outbreaks of influenza or other acute respiratory infections!

Acute respiratory infections (like the common cold or the flu) have been detrimental to civilizations for centuries. While research has come a long way, the annual influenza epidemic persists – indicating the need for improved understanding of viral transmission. The C.A.T.C.H. the Virus Study is designed to investigate ARI contagiousness and to help make our communities healthier.
