Patient's question:
How infectious is the Epstein-Barr virus? The child has been like this for a while, and they are reluctant to give medication. Please give the doctor some advice.Doctor's answer:
Hello, the infectivity of EB virus is not very high. Contact with family members of patients can lead to transmission. Patients and EBV carriers are the sources of infection. The virus is abundant in salivary glands and saliva, and can persistently or intermittently shed for weeks, months, or even years. It can occasionally be transmitted through blood transfusions and feces. This disease is more common in children and adolescents, with no significant gender differences. Children under 6 years old often have asymptomatic or mild infections, while infections after 15 years of age more commonly present with typical symptoms. After onset, persistent immunity is acquired, and secondary infections are rare. The main transmission route is through close oral contact (oral-oral transmission), although droplet transmission is also possible.
