COVID-19 patients reinfected with the novel coronavirus might experience more severe symptoms than before, a study has claimed. The study, published in the journal Lancet Infectious Diseases, found evidence that an individual with no known immune disorders or underlying conditions was infected with the SARS-CoV-2 virus during two separate instances. According to scientists, the patient, a 25-year old male, was infected with two distinct SARS-CoV-2 variants within a 48-day time frame, while testing negative in between the two infections.
