Abstract
Sir—TT virus (TTV), which was discovered in 1997, is the first identified circovirus-like virus that infects humans. To date, TTV has not been formally associated with any disease in humans, even when highly divergent TTV isolates that belong to the SEN family are present, as reported by Chamberland in a recent review [1]. In the general population, reported prevalences of TTV infection are up to 80% [2], and the virus is most often detected in serum and saliva [3]. Transmission of the virus is suspected to occur through multiple pathways and, in particular, through saliva droplets. Mother-to-infant transmission of TTV is uncertain and is not well documented [4, 5]. We report the findings of early follow-up of a full-term female newborn, along with the findings for both parents.
