Polyomavirus infections after transplantation and immunosuppression could result from endogenous reactivation, but proof of this concept is lacking.
Last, we do not believe that our study represents polyomavirus infections during childhood worldwide.

Most polyomavirus infections documented by urine cytology or serology are asymptomatic and are believed to be of minimal clinical significance.[1]
Seroepidemiologic data for BKV, JCV, and MCPyV indicate that human polyomavirus infections are ubiquitous and generally occur without apparent disease.
BK virus (BKV) and John Cunningham virus (JCV), for example, are ubiquitous human polyomavirus infections. Seroconversion for both occurs largely in childhood, with BKV seroprevalence reaching 75% among children >9 years of age and JCV seroprevalence estimated at >23% among those >10 years of age (17).

Polyomavirus belongs to Papovaviridae, among which, BC virus (BCV) and JC virus (JCV) can induce diseases.1,2 It has been reported that,3 patients who undergo renal transplant usually have weak immune function, which improves possibility of polyomavirus infection. Polyomavirus can be activated again in about 10% ~ 60% renal transplant recipients, but without affecting renal function; 1%~10% renal transplant recipients may have polyomavirus-associated nephropathy (PVAN).
