Few Americans have been diagnosed with COVID-19 themselves, but many more say they know someone with a positive diagnosis. More than one-in-four U.S. adults (28%) say they personally know someone who has been diagnosed by a health care provider as having COVID-19. A smaller share of Americans (20%) say they know someone who has been hospitalized or who has died as a result of having the coronavirus.

Only 2% of U.S. adults say they have been officially diagnosed with COVID-19 by a health care provider, according to a Pew Research Center survey. And 2% say they have taken a blood test that showed they have COVID-19 antibodies, an indication that they previously had the coronavirus. But many more Americans (14%) say they are “pretty sure” they had COVID-19, despite not getting an official diagnosis. And nearly four-in-ten (38%) say they’ve taken their temperature to check if they might have the disease.

One aspect of personal risk for exposure to the coronavirus is whether someone is employed in a setting where they must have frequent contact with other people, such as at a grocery store, hospital or construction site. Given the potential for the spread of the coronavirus within households, risk to individuals is also higher if other members of the household are employed in similar settings. Among people who are currently employed full-time, 35% are working in a job with frequent public contact. Among those working part-time, almost half work (48%) in such a setting. For those living in a household with other adults, 35% report that at least one of those individuals is working in a job that requires frequent contact with other people.

Taken together, nearly four-in-ten Americans (38%) have this type of exposure – either currently working in a job that requires contact with others, living in a household with others whose jobs require contact, or both. Hispanics (at 48%) are more likely than either blacks (38%) or whites (35%) to have this type of personal or household exposure.

Interpersonal exposure in the workplace is also more widespread among younger adults. And there is a 10 percentage point difference between upper- and lower-income Americans in exposure, with lower-income adults more likely to work in situations where they have to interact with the public, or to live with people who do.

Self-reports of an underlying health condition vary greatly by age. Among those ages 18 to 29, just 16% say they have a condition; this rises steadily with age to 56% among those 65 and older. Whites are a little more likely than blacks and Hispanics to report having a health condition, but both blacks (at 54%) and Hispanics (52%) are far more likely than whites (32%) to say that the coronavirus outbreak is “a major threat” to their health.
