Herpes simplex virus type 2 infection is a quite common but frequently asymptomatic, therefore undiagnosed condition. Genital HSV-2 infection may cause neonatal herpes, enhances HIV transmission and may play a role in infertility. To evaluate the prevalence of HSV-2 in Hungary we tested 2500 serum samples for the presence of anti-HSV-2 IgG by ELISA method. According to our results Hungary belongs to the low-infected countries, the HSV-2 seroprevalence grows with age and is significantly higher among women than in men. We also examined the serostatus of 512 pregnant women and 539 women attending infertility clinics. Results show that the HSV-2 prevalence is significantly higher among women attending infertility clinics and the seropositivity of pregnant women is similar to that of the general Hungarian women population with the same age.

Torque teno virus (TTV) belongs to the floating genus of
. It was discovered in a human patient, and later it was also found in animals including pigs. The aim of this study was to investigate the presence and estimate the prevalence of swine TTV in Hungarian pig herds for the first time, and to characterise the viruses found. Serum samples of 82 adult swine from 13 piggeries and 44 weaned pigs from one large herd were tested by PCR for the presence of TTV DNA. Viral DNA was found in 30% of the adult swine and 73% of the weaned pigs tested. Liver and intestine of weaned pigs were also tested and found to be infected at a lower rate. The TTV sequences found in sera and intestines were similar and could be clustered as swine genogroup 1. However, the sequences derived from one liver were remarkably different from all other known genogroups and seemed to represent a new genogroup.
