Genetics of COVID-19 Susceptibility and Manifestations

Official Study Title: Genetics of COVID-19 Susceptibility and Manifestations (COVIDcode)

The goal of this study is to learn more about the genetic contributions to the severity of disease in COVID-19. We hope to use this information to develop therapies to reduce the severity of symptoms of COVID-19 in some people.

What does the study involve?

Participants will complete a questionnaire about their health history and COVID-19 symptoms.

Participants will give a blood or saliva sample. It will be about 2 tablespoons of blood, or we will send a saliva collection kit. Researchers will use this blood or saliva sample to study the participant’s DNA.

Who can participate?

Anyone located in the United States who has tested positive for SARS-CoV-2 infection may be eligible to join (including NIH staff).

Where is it taking place?

We will work with you to collect a blood sample or will send a saliva collection kit.

Is there a cost?

There is no cost to participate.

Is compensation provided?

We offer compensation of up to $70 for completing protocol activities.

Number of visits

There will only be one visit required for a blood draw.
