What is active Epstein-Barr virus infection?

Active EB virus infection usually refers to chronic active EB virus infection, a viral disease caused by persistent or recurrent Epstein-Barr virus (EBV) infection. The detailed analysis is as follows:

Active EB virus infection is a disease triggered by extensive replication of the Epstein-Barr virus after it invades the human body. EB virus primarily spreads through saliva. Once entering the body, it infects lymphocytes and replicates within them. When viral replication is active, the immune system is activated, leading to symptoms such as fever, sore throat, and swollen lymph nodes. Some individuals may also experience fatigue, rash, and enlargement of the liver or spleen. This infection commonly occurs in people with weakened immune systems, particularly adolescents and children. Close contact with an infected person's saliva, or sharing items such as eating utensils or toothbrushes, increases the risk of infection.

Daily care should focus on strengthening physical health and preventing transmission. During infection, ensure adequate rest and avoid staying up late or engaging in strenuous exercise, allowing the body sufficient energy to fight the virus. Choose light, easily digestible foods and consume plenty of fresh fruits and vegetables to supplement vitamins. Avoid spicy or irritating foods that could worsen throat discomfort. Maintain good personal hygiene by washing hands frequently, not sharing personal items, and covering the mouth and nose when coughing or sneezing. Use physical methods to reduce fever; if symptoms persist or worsen, seek medical attention promptly. After recovery, continue maintaining healthy lifestyle habits, including regular sleep patterns and a balanced diet, to enhance immunity and reduce the risk of reinfection.
