Reinfection after getting covid19 once was thought not to happen as
patient would have developed immunity against the virus. But recently a
case has been reported from Hongkong where the second episode of
asymptomatic infection occurred 142 days after the first symptomatic
episode in an apparently immunocompetent patient. Epidemiological,
clinical, serological and genomic analyses confirmed that the patient
had re-infection with another strain of SARSCOV2 virus instead of
persistent viral shedding from first infection. Here we report two
children who got re-infected with SARSCOV2 after recovering fully and
developing IgG antibodies it.
