Tuberculosis cases reported in the United States appear to be returning to levels seen before the Covid-19 pandemic, according to a new report from the US Centers for Disease Control and Prevention.

The US incidence of tuberculosis, or TB, increased slightly last year after a substantial 20.2% decline in 2020 and a 9.8% increase in 2021, according to the data published in the CDC’s Morbidity and Mortality Weekly Report on Thursday, just a day ahead of World Tuberculosis Day.

“TB incidence increased during 2022, compared with that during 2020 and 2021,” CDC researchers wrote in the report. Now, the incidence “appears to be returning to prepandemic levels among U.S.-born and non-U.S.-born populations.”
