“…In summary, the highest percentage of TTV infection is among Hepatitis B patients while the lowest is in cardiovascular diseases (CVD) patients. This result is in agreement with other studies which reported more than 70% TTV positivity (Koohi et al, 2012;Hussain et al, 2012b;Magu et al, 2015;Izadi et al, 2016) among hepatitis patients. The low percentage of TTV infection in non-hepatic diseases have been postulated to have an association with less exposure to blood transfusion.…”

Torque teno virus (TTV) is one of the "orphan" viruses that have been discovered almost two decades ago, with little information on the relationship of the infection to any diseases. It is one of the 45% of the commensal virus which is found throughout the population and becoming one of the most extensively studied viruses on its prevalence among the various level of health status. From healthy blood donors to patients who suffered severe illness, TTV infection level seems to be high and the findings have triggered interest from the researcher. Even though the study on TTV prevalence is actively performed, the actual pathogenesis of TTV to any specific diseases is yet to be ascertained. Many suggestions on the possible association of TTV infection with severe diseases such as acute respiratory diseases, liver-related diseases and even cancer have been discussed. However, one type of diseases which might have an association with TTV is hepatitis. Albeit, it remains a theory as the actual pathogenicity of TTV is not fully understood.

Background: Hepatitis E virus (HEV) infection poses a major public health issue in countries with poor drinking water supply, inadequate rd sanitation and improper disposal of human excretes. It causes fulminant hepatitis in pregnant women during 3 trimester with a high mortality rate of 20-30%. Aim:The aim of the study was to estimate the seroprevalence of HEVinfection among pregnant women in South India. Materials and methods: Atotal of 200 asymptomatic, pregnant women were included in the study was evaluated using a questionnaire form. 5ml of blood samples were collected from them and serum was separated to detect for the presence of HEV-antibodies and HEV-RNA by ELISA test and RT-PCR test respectively. Results: The prevalence of HEV-antibodies was found to be 11.5%. HEV-RNA was not present in any participants. A very high statistical signicance was seen associated with the risk factors such as educational status, source of drinking water, type of toilet system used, and the habit of hand washing after using toilets (P<0.01). Conclusion: Even though the prevalence of HEV among the pregnant women is low, periodic assessment and screening of the pregnant women should be done. Encouraging the public sector to strictly adhere to the personal hygienic measures will denitely have an impact in the maternal as well as perinatal mortality and morbidity

The Association of Prevalence and Genotypes of Torque Teno Virus (TTV) Among Chronic Hepatitis B and C Patients in Ahvaz, 2012

Abstract: Background: Torque teno virus (TTV) belongs to the Circoviridae family and was separated from Japanese patients with elevated levels of serum alanine transferase for the first time. Following this, extensive studies have been carried out around the world.
