Immunosurveillance and Experiences of COVID-19 in North Dakota

About this project


The Immunosurveillance and Experiences of COVID-19 in North Dakota project seeks to better understand the level of population immunity to COVID-19 brought on from natural infection, vaccination, or both and to understand the COVID-19 experiences of the citizens of North Dakota. We will do this through the identification of antibodies and T-cells to SARS-CoV-2, the virus that causes COVID-19, or to the spike protein made from the vaccine. These different tests of immunity can help identify if people have been infected by the virus in the past (even if they never had symptoms), have developed an immune response to a vaccine, or both. PCR testing will identify presence of the virus indicating current infection. This information will provide insight into how our communities might be protected against later infection.

Participant Selection

The project has two arms: survey only (representative population sample of North Dakota) and survey with blood and saliva sample collection (Fargo, Grand Forks, Bismarck, Williston, Dickinson, Minot, and Sioux County). Participants will be recruited using two methods. Invitations were sent to a random sample of addresses selected from a list of all US Postal Service addresses in North Dakota to complete the survey. Each mailing for participants in this portion includes an invitation letter and a survey for one adult to complete. Participation will be based only on those that voluntarily return the survey. Participation for the sample collection events will be through recruited volunteers surrounding each of the seven communities (Fargo, Grand Forks, Bismarck, Williston, Dickinson, Minot, and Sioux County). Volunteers must be a North Dakota resident aged 18 years or older. Interested participants can fill out a registration form (found on the ‘Event Registration’ page) or can contact the project team at or 701-231-2219 to participate in the testing events.


The survey will collect information about people’s experiences during the COVID-19 pandemic in North Dakota. This information can be used to understand how citizens experienced COVID, identify gaps in the system response, and inform public health response to COVID-19, future outbreaks, or other public health emergencies. Survey data includes self-reported access to vaccine and testing, experiences with COVID-19 symptoms, access to healthcare and health insurance coverage during the pandemic, opinions about the COVID-19 response, as well as general health and demographic information. Both those recruited to the survey only arm and volunteers who participate in the sample collection events will be asked to fill out the survey.

Sample Collection

Sample collection events will be held in each of the seven communities (Fargo, Grand Forks, Bismarck, Williston, Dickinson, Minot, and Sioux County). Events will be staffed by project team members and phlebotomists from the North Dakota Department of Health, where blood samples and COVID-19 oral swabs will be collected. Blood samples will be tested using antibody tests for SARS-CoV-2, the virus that causes COVID-19. Saliva swabs will be used to identify  active SARS-CoV-2. PCR testing of the swabs will be conducted at the NDDoH lab.
