Covid19 Reinfection in Two Children with Cancer

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.
