no direct benefits to you from participating in this study. However, the information you provide
may help improve public health efforts with regards to the new coronavirus and, thus, reduce
harm from this epidemic. We cannot and do not guarantee or promise that you will receive any
benefits from this study.

PAYMENTS: You will receive $1.50 as payment for your participation.

PARTICIPANT'S RIGHTS: If you have read this form and have decided to participate in this

Start of Block: Introduction

Q4.2 A new virus (of the coronavirus family) emerged in Wuhan, China, in 2019. We will refer to
this virus from now on simply as “the new coronavirus”. We would love to find out what the
general public in the United States knows about this new virus.

For this research to be helpful to public health efforts, it is important that you refrain from looking
up any answers online. A lot of aspects about this virus and the illness it causes are still
unknown, so much of the time there is no correct answer. Please just give it your best guess. All
you need to do to receive your payment is to fill out the answers to the best of your knowledge.
