Diagnosis of cytomegalovirus (CMV) primary infection is reliable, but diagnosis of CMV non-primary infection (NPI) is questionable. Our aim is to highlight the difficulties met in diagnosis of CMV NPI. We illustrate that in proven cases of CMV NPI, very different serologic and molecular patterns may be observed and that routine serologic testing may fail to help with diagnosis. These results point out that many data available in literature concerning the prevalence of NPI, materno-fetal transmission rates and consequences of NPI may be wrong. We need to know how frequently they occur, are transmitted and cause fetal damages. Diagnosis of NPI must be improved, along with our understanding of the mechanisms leading to intrauterine CMV transmission and congenital infection in babies born to women with preexisting immunity.

Cytomegalovirus (CMV) is the most common cause of viral infection in newborn babies, and affects 1 in 200 of all live born infants in high-income countries; and 1 in 71 in low- and middle-income countries. It is a major cause of hearing loss and brain damage. Women may get CMV infection for the first time during pregnancy (primary infection) or may experience 'non-primary' infection, either by reactivation of previous CMV infection or by a new infection with a different strain of the virus.

Objective: Chronic hepatitis B virus (HBV) infection is a major disease that seriously affects the health of patients. In this paper, the relationship among MTHFR gene polymorphism, MTRR gene polymorphism and 1762/1764 mutation in the BCP region of HBV gene with disease progression in chronic HBV patients was studied.
Methods: A total of 144 chronic HBV infection patients from January 2021 to June 2022 in the Third People's Hospital of Zigong City, were included as the study subjects.
