We report the case of a 93-year-old woman on haemodialysis treatment for more than 30 months and with multiple comorbidities who recovered from a Covid-19 infection without any significant clinical problems. The patient has shown a delay in viral clearance with swab test negativization (confirmed) after 33 days; after testing positive again, she has resulted persistently negative, (confirmed after 49 days).
After the first negative swab, IgG and IgM antibodies have been found; these have remained persistently positive after a month. As well as highlighting an unexpected resilience in an extremely fragile context, the analysis of this case draws attention to patients’ management and, potentially, to the need to arrange dialysis treatments in isolation for some time after their “laboratory recovery”.
