Viral infections are risk factors for cervical cancer, 80% of liver cancers, and 15–20% of the other cancers. [2] This proportion varies in different regions of the world from a high of 32.7% in Sub-Saharan Africa to 3.3% in Australia and New Zealand. [1] A virus that can cause cancer is called an oncovirus or tumor virus.
Healthy individuals can be infected with the virus and show no signs or symptoms, due to the immune system's ability to keep the infection in check. Infection is of particular concern to the immunocompromised. Cancer patients receiving chemotherapy, AIDS patients, and organ transplant patients are all at a high risk of showing signs of infection.
Genital herpes is a herpes infection of the genitals caused by the herpes simplex virus (HSV). [1] Most people either have no or mild symptoms and thus do not know they are infected. [ 1 ] When symptoms do occur, they typically include small blisters that break open to form painful ulcers . [ 1 ]

[ 3 ] [ 25 ] It is the second-most common cause of female-specific cancer after breast cancer , accounting for around 8% of both total cancer ...
A Phase I/II study completed in 2008 evaluating NV1020 for treatment of metastatic colorectal cancer in the liver. [19] The study assessed tumour response by CT scan and FDG-PET scans, showing 67% of patients had an initial increase in tumour size then followed by a decrease in 64% of patients. [20] [18]
Herpes simplex, often known simply as herpes, is a viral infection caused by the herpes simplex virus. [5] Herpes infections are categorized by the area of the body that is infected.

It can cause a woman to have a potentially deadly ectopic pregnancy, in which the egg implants outside of the uterus. However, chlamydia can be cured with antibiotics. The two most common forms of herpes are caused by infection with herpes simplex virus (HSV). HSV-1 is typically acquired orally and causes cold sores; HSV-2 is usually acquired ...
HHV-6 re-activation causes severe disease in transplant recipients and can lead to graft rejection, often in consort with other betaherpesviridae. Likewise in HIV/AIDS, HHV-6 re-activations cause disseminated infections leading to end organ disease and death. Although up to 100% of the population are exposed (seropositive) to HHV-6, most by 3 ...
