A new study from the University of Utah suggest there’s a 12% chance of getting the novel coronavirus from someone in your home who has the virus.

The study — a part of Phase One of the Utah Hero Project from the University of Utah — tested thousands of Utah residents.

  • 8,500 Utahns from ages 12 and up were tested.
  • The subjects were from Davis, Salt Lake, Summit, and Utah counties.

“Close examination of COVID-19 cases worldwide has already taught us that new coronavirus infection spreads more readily when people are close to one another indoors for long periods of time. That characterizes the living condition of many homes — and yet spread from one person in a household to another fails to happen about 88% of the time. What, then, could make the difference between who is likely to spread the virus and who is not?” — University of Utah Health’s Julie Kiefer wrote, according to KSL.com.

Kiefer said one of the reasons for high infection rates is due to “superspreaders.” According to Kiefer, 10% to 20% of infected people can create 80% of cases, according to KSL.com

Another study said something similar

Back in mid-August, data from the Utah Department of Health found that just under 18,000 of the state’s near first 47,000 confirmed cases since the pandemic began were transmitted between family members or roommates, as the Deseret News reported.

State public health officials warned large households to be cautious.

  • “If there’s someone vulnerable in your household, all family members should take extra precautions to avoid exposure to COVID-19. If possible, those at high risk should avoid caring for children. Sick family members should be separated from the higher risk person. All family members should wear face masks in public, keep physical distance in public and wash their hands whenever they return home,” state health department officials said at the time, according to the Deseret News.
