BK Virus Infection Market Set to Grow by 2035 – BIS Research

The global BK virus infection market is expected to expand steadily through 2035, supported by the rising population of immunocompromised patients, particularly kidney transplant recipients. With BKV nephropathy affecting up to 6.6% of transplant cases, the demand for effective diagnostics and therapeutic solutions continues to increase. Growth is underpinned by increased routine screening, off-label antiviral use, pipeline immunotherapies, and expanding transplant programs worldwide.
Published 11 September 2025

What Is BK Virus Infection? 

BK virus is a polyomavirus that remains latent in most healthy individuals. However, in immunocompromised patients—especially kidney transplant recipients—it can reactivate, leading to BK virus nephropathy (BKVN). This condition damages transplanted kidneys, often progressing silently until graft function is impaired. Current management includes reducing immunosuppression and off-label antivirals, as there are no FDA-approved BKV-specific drugs. 

What Is the Market Outlook? 


  • Therapeutic Innovation: Development of targeted antivirals and immunotherapies, such as adoptive T-cell therapy, aimed at addressing unmet needs. 
  • Diagnostic Expansion: Increased adoption of PCR-based viral load testing and molecular assays enabling precision treatment. 
  • Commercialization Push: Biopharma players advancing clinical trials of BKV-specific therapies and integrating companion diagnostics.
