About CATS

Welcome to the website for the Covid-19 and Trust in Science (CATS) Project. CATS is housed at the Interdisciplinary Center for Innovative Theory and Empirics at Columbia University, led by Gil Eyal, Cristian Capotescue, and Larry Au.

We are interested in the experiences of recovering or recovered Covid-19 patients. We are especially interested in those who have Long Covid (or Long Haul Covid or Post-Covid Syndrome), which is understood broadly as the persisting symptoms and complications arising from Covid-19 that last for weeks and months, well beyond the period of acute illness [1]. These symptoms vary according to patient, but include symptoms such as fatigue, brain fog, and respiratory distress [2]. Researchers have estimated that about 10 to 35% of those with Covid-19 develop Long Covid [3].

CATS aims to document: (1) the experience of recovering Covid-19 patients and Long Covid patients as they attempt to gain access to medical care and support; and (2) the sources of trustworthy information that Long Covid patients rely on to make decisions about their own health and wellbeing.

If you have recovered from Covid-19, are recovering from Covid-19, or consider yourself to be a Long Covid patient and are aged 18 or above, we would be grateful if you could complete the CATS survey. At the end of the survey, you will be asked if you would be interested in participating in a follow up interview conducted by one of the CATS researchers where we hope to learn more about your experience. Any information you provide will be used to inform our research, and your name and contact information will be kept confidentially. Participants who successfully complete an interview will receive a $25 gift card.
