In brief: Mostly Bacterial
Bacteria are much more common, especially ecoli.
Viruses are the rare cause of bladder infection in an immunocompetent person, while they are increasing among immunocompromised patients especially in hemorrhagic cystitis, a type of bladder inflammation. Bk virus, adenovirus, and cytomegalovirus are the main ones. No matter what, bacterial bladder infection is much more common.

In brief: Bacterial
Most bladder infections, as we know them, are caused by bacteria with the most common bacteria being e.
Coli. Viral infections can occur in any part of the body and the urinary tract is not any different, however, it is difficult and uncommon to test for viral infections of the bladder.
