Rapid increase in total torquetenovirus (TTV) plasma viremia load reveals an apparently transient superinfection by a TTV of a novel group 2 genotype.
An apparently transient infection by a superimposed torquetenovirus (TTV) in a subject who already carried three different genotypes of the virus is described. The superinfection induced a rapid increase in the plasma TTV load and a decline in immunocomplexed virus. The superinfecting TTV was a novel group 2 genotype.
