The male patient, aged 75 with underlying illnesses, travelled to Changping, Dongguan alone on November 28 and attended a hospital there for chest discomfort on December 8. He returned to Hong Kong via Lo Wu on December 9 and was directly admitted to North District Hospital by ambulance for cough with sputum, shortness of breath, runny nose and chest discomfort. His nasopharyngeal swab tested positive for enterovirus/rhinovirus and negative for influenza virus upon testing by the CHP's Public Health Laboratory Services Branch (PHLSB).

The patient subsequently developed fever on December 17 and the clinical diagnosis was pneumonia. His nasopharyngeal aspirate collected on 19 December was confirmed to be positive for influenza A(H7N9) virus by the PHLSB tonight.
