State Health Commissioner Dr. Kris Box has become reinfected with COVID-19. She tested positive after developing symptoms on Monday, and has been isolating at home.
Box also tested positive for COVID-19 in October 2020 after members of her family got sick – she was asymptomatic. She is fully vaccinated and received her booster shot in November.
The Indiana Department of Health said in a news release Box’s PCR test will be sequenced to determine if she has been infected with the omicron variant.
Box is an example of both a reinfection and a breakthrough case. Indiana has reported more than 16,000 reinfections since Sept. 1. Nearly 113,000 fully vaccinated Hoosiers have had breakthrough cases.

The Centers for Disease Control and Prevention says it anticipates more breakthrough cases with the highly transmissible omicron strain. But it also says vaccines are still effective at preventing serious illness and death.
