Then in August he visited Spain and while returning to Hong Kong he was found positive again at the airport. In the first he was symptomatic while he was asymptomatic in the second infection. Hong Kong researchers did a genome sequencing on the patient and confirmed reinfection, revealing that in the first instance he was infected with the prevalent Asian strain of SARS-CoV-2 an
