Oregon Tuberculosis Data
During 2020, 67 cases of TB disease were reported in Oregon, corresponding to an incidence of 1.6 cases for every 100,000 Oregon residents. This represents a 5% decrease from the 2019 incidence rate of 1.7/100,000.
Nationwide, in 2020 TB cases decreased by 20% during the COVID-19 pandemic to a rate of 2.2 cases for every 100,000 U.S. residents. This reduction in incidence is likely due to decreased transmission due to COVID-19 mitigation measures and/or reduced or delayed diagnosis of TB cases. Oregon remains a medium-incidence state for TB disease and despite the steep nationwide decline, is still well below the national case rate.
In 2020, 2 (4%) of tested isolates were resistant to isoniazid, a primary first-line TB drug, and there were no cases of multi-drug resistant TB (TB that is resistant to at least isoniazid and rifampin). Five cases of TB were treated in children under the age of 14, and there were no cases co-infected with TB and HIV.
