A paper to be published in May in the U.S. Centers for Disease Control and Prevention's (CDC/US) journal Emerging Infectious Diseases (EID) shows that a first exposure to COVID-19 in mild or asymptomatic cases may not produce an immune response, and that a person can reinfect himself or herself with the same variant. The second infection can cause stronger symptoms than the first, the study indicates.
