TABLE 3. Clinical findings, hospitalization status, and real-time PCR test results in patients* with confirmed psittacosis cases (n = 13) associated with a psittacosis outbreak — Georgia and Virginia, 2018.

Abbreviations: BAL = bronchoalveolar lavage; Ct = cycle threshold; ICU = intensive care unit; Neg = negative; NP = nasopharyngeal; PCR = polymerase chain reaction; Pos = positive.

* All specimens associated with an individual patient were collected on the same day unless otherwise noted. For example, sputum, NP swab, and stool specimens for patient A were all collected on the same day, but specimens from patient A were not necessarily collected on the same day as were those from patient B.

^† ”Pos” indicates Chlamydia psittaci was detected. “Neg” indicates C. psittaci was not detected. Ct values represent the real-time PCR amplification cycle at which CPSIT_RS01985 amplification was first detected. Ct values are displayed only for C. psittaci–positive specimens, because CPSIT_RS01985 was not detected in C. psittaci–negative specimens.

^§ Radiograph-confirmed pneumonia.

^¶ Dashes indicate specimen type was not submitted to CDC.

** Sputum was collected 3 days after the NP swab.

^†† Sputum was collected 1 day after the NP swab.

^§§ Two NP swabs were tested; one tested positive and one tested negative. The negative NP swab was collected 2 days after the positive NP swab.
