  1. CuV cutavirus, M man, W woman, y year
  2. a A total of 46 subjects could be tested for CuV DNA in the second specimens
  3. b Defined as the presence of CuV DNA at the two consecutive visits with an interval of approximately 6 months
  4. c Defined as the new detection of CuV DNA that was not detected at the first visit
  5. d Second specimens were obtained from subjects who tested positive for CuV DNA in the first specimens and measured for viral copy number after an interval of approximately 6 months
  6. e Second specimens were obtained from subjects who tested negative for CuV DNA in the first specimens and measured for viral copy number after an interval of approximately 6 months
