Case 2
A woman in her mid-70s from Wuhan landed at Suvarnabhumi airport on 13 January. She travelled to Thailand with three family members as part of a tour group of 20 (including the case). An airport thermoscanner detected a fever of 38.0 °C that was confirmed with a tympanic thermometer. The patient reported a sore throat, that her fever onset date was 13 January and that she had a cough for an undetermined period. The patient was hospitalised at BIDI. Upon admission, she reported mild tachypnoea, and her CXR was compatible with pneumonia. Similar to case 1, the first CXR taken on 13 January, showed thickening interstitial lung marking at both lower lung fields and both perihilar regions because of interstitial infiltration or crowded lung marking, mild cardiomegaly and dilated aorta. Follow-up CXR on 17 January additionally showed recent hazy with reticular opacities at left middle lung field. The patient was not in severe condition but stable.
In the patient interview, she reported that she did not visit the Huanan Seafood Market or other markets. She also reported no contact with pigs, camels, other mammals (or areas with dead birds), or any consumption of raw or undercooked foods. She stated that she was not in contact with persons with respiratory symptoms.
A conventional nested RT-PCR test of this patient was positive for the CoV family [9]. Subsequent genome sequencing was again compatible with the SARS-CoV-2 and shared via the GISAID EpiCoV database (EPI_ISL_403963). A nasopharyngeal swab also tested positive by RT-PCR for adenovirus. The patient was no longer febrile as of 17 January, and after testing negative for the CoV family by conventional nested RT-PCR, she was discharged and she returned to China.
