Woman tests coronavirus-positive for record 105 days

The patient with chronic lymphocytic leukaemia remained infectious for much of the time

An asymptomatic elderly woman with chronic lymphocytic leukaemia tested positive to coronavirus for a landmark 105 days, and remained infectious for much of that time, US researchers are reporting.

The case highlights the risk of immunocompromised patients shedding infectious virus for longer than expected because of their impaired ability to mount an immune response, say the researchers from the National Institute of Allergy and Infectious Diseases.
