SARS-COV2 Pandemic Serosurvey and Blood Sampling

Sponsored by National Institute of Allergy and Infectious Diseases (NIAID)

Respiratory virus outbreaks and pandemics, such as SARS, MERS, and the new SARS-COV2 virus, have major impacts worldwide. Researchers must act quickly to learn about the exposures and immunity in the general population. This can be done by studying people's blood serum to find those with antibodies to the virus. This knowledge can help in current and future pandemics.

In this study, researchers want to find people who have anti-SARS-COV2 antibodies but no known exposure or illness.


Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. The virus that causes COVID-19 is a novel coronavirus that was first identified during an investigation into an outbreak in Wuhan, China.

How is this study designed?

Participants will give a blood sample. They can go to the NIH Clinical Center or do home blood sampling.

Study Type: Observational Estimated Enrollment: 1000 participants Estimated Study Start Date: April 15, 2020 Estimated Study Completion Date: March 31, 2022

Who is this study for?


  • >= 18 years of age.
  • Willing and able to complete a verbal telephone consent.
  • Willing to undergo one blood draw or home blood sampling.
  • Willing to have blood samples stored for future research.


  • Confirmed history of COVID19 infection or exposure
  • Current symptoms consistent with COVID19 infection

* The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

What should I expect?

Participants will enroll and give consent over the phone. They will be screened over the phone with a health assessment questionnaire. They will be screened for COVID19 using the NIH COVID19 screening questionnaire.

Participants will give a blood sample. They can go to the NIH Clinical Center or do home blood sampling. In-person collection at NIH is preferred.

  • If participants go to NIH, 2 tubes of blood will be taken.
  • If participants do home sampling, they will be sent a home sampling kit. The kit contains gauze, an alcohol pad, a lancet, collection devices, and shipping materials. It also contains detailed instructions. They will collect 80ul of blood and mail it to the NIH lab.

Participants may enroll in the study up to 4 times. They cannot enroll within 30 days of previous enrollment.
