Timeline of 8 patients included in a study of TB diagnostic delays and treatment outcomes among patients with COVID-19, California, USA, 2020. Symptom onset is the date the first symptoms compatible with either TB or COVID-19 was identified. Symptom onset for patient 6 was in June 2019. Patient 7 was hospitalized for reasons unrelated to TB or COVID-19, and the TB diagnostic work-up was prompted by incidental findings on chest imaging. The healthcare visit of a missed opportunity to diagnose TB in a person with TB risk factors was a visit where >1 symptom or chest imaging finding was known. Yellow shading captures the number of days between the first missed opportunity and the first specimen collection for a TB diagnosis. Elevated COVID-19 incidence in California was considered >15 cases/100,000 population (7-day average rate). TB, tuberculosis.
