PARIS, KOMPAS.com – Patients who experienced Covid reinfection may experience more severe symptoms the second time they are infected, according to a study released Tuesday.
The research finding was published in The Lancet Infectious Diseases journal confirming that it is possible for a person to experience Covid-19 reinfection.
The study charts the first confirmed case of Covid-19 reinfection of a Nevada man which indicates that exposure to the virus may not guarantee future immunity.

The Covid reinfection patient, a 25-year-old Nevada man, was infected with two distinct variants of SARS-CoV-2, the virus that causes Covid-19, within a 48-day time frame.
The second Covid-19 infection was more severe than the first, resulting in the patient being hospitalized with oxygen support.
The paper noted four other cases of reinfection confirmed globally, with one patient each in Belgium, the Netherlands, Hong Kong, and Ecuador.
