A 25 yr old patient in Nevada has a confirmed case of #COVID19 reinfection (48 days apart between 1st and 2nd PCR).
This time, unlike the case in Hong Kong, the immune system did not protect this person from reinfection or disease. (1/n)

During the 1st infection in April, patient recovered after about a month in isolation, testing negative for viral RNA in 2 subsequent tests. Patient was well until end of May, became ill and tested positive 2nd time. This time needing hospitalization & oxygen support. (2/n)
Viral genome of 1st and 2nd isolates differed significantly, indicating that reinfection occurred. (3/n) 
This case highlights the need for further examination of the range of outcomes from reinfection by #COVID19. As more and more reinfection cases will be reported, we should get a better sense of how well the immune system after natural infection protects against disease. (End)
