EBV infection for 5 months can hardly lead to lymphoma. Although EBV infection may lead to inactivation of oncogenes in the body and active cellular proto-oncogenes, accompanied by decreased immunity, which may cause abnormal cell growth and malignant diseases such as lymphoma, this process is very long and usually takes several years to more than ten years, and it is very difficult to cause lymphoma within 5 months. In addition, lymphoma is the result of many factors, mostly considered to be related to viral infection, genetic factors and living environment, etc. EBV infection is only one of the reasons, and not all EBV infected people will evolve into lymphoma.
