PCR analysis showed that DNA from human anellovirus species TTV and TTMDV, but not TTMV, were more prevalent in febrile patient specimens compared to afebrile controls.

<p><b>A–C</b>. PCR identified TTV (<b>A</b>) and TTMDV (<b>B</b>) in a higher percentage of febrile patients compared to afebrile controls while TTMV (<b>C</b>) was present in equivalent percentages (plasma TTV, p = 0.0567; NP TTV, p = 0.0182; patient TTV, p = 0.0026). <b>D</b>. The majority of patients were either positive or negative for TTV, TTMDV, and TTMV DNA in both their plasma and NP specimens. P-values determined by chi-squared test.
