The virus causes measles, a highly contagious disease transmitted by respiratory aerosols that triggers a temporary but severe immunosuppression.Symptoms include fever, cough, runny nose, inflamed eyes and a generalized, maculopapular, erythematous rash and a pathognomonic Koplik spot seen on buccal mucosa opposite to lower 1st and 2nd molars.
Pneumonia is the most common fatal complication of measles infection and accounts for 56–86% of measles-related deaths. [89] Possible consequences of measles virus infection include laryngotracheobronchitis, sensorineural hearing loss, [51] and—in about 1 in 10,000 to 1 in 300,000 cases [90] —panencephalitis, which is usually fatal.

HPV is the most common virus that infects the reproductive tract. Infection can lead to the development of cervical cancer in women. Viral infection is a major risk factor for cervical and liver cancer. [61] A virus that can cause cancer is called an oncovirus.
HIV does not directly cause cancer, but it is associated with a number of malignancies, especially Kaposi's sarcoma, non-Hodgkin's lymphoma, anal cancer and cervical cancer. Kaposi's sarcoma is caused by human herpesvirus 8. AIDS-related cases of anal cancer and cervical cancer are commonly caused by human papillomavirus.
Measles is considered one of the most contagious diseases, Russo notes, making it easy to spread quickly among unvaccinated people. "Some of these diseases are potentially lethal," he says.
Efforts to induce this phenomenon have used cancer vaccines (derived from cancer cells or selected cancer antigens), or direct treatment with immune-stimulating factors on skin cancers. [53] Some oncolytic viruses are very immunogenic and may by infection of the tumour, elicit an anti-tumor immune response, especially viruses delivering ...
Measles was eliminated in the Americas last year, but there's one reason for lingering outbreaks. Officials: Measles outbreak caused by anti-vaccination campaign Skip to main content
Subacute sclerosing panencephalitis (SSPE), also known as Dawson disease, is a rare form of progressive brain inflammation caused by a persistent infection with the measles virus. The condition primarily affects children, teens, and young adults. It has been estimated that about 2 in 10,000 people who get measles will eventually develop SSPE. [1]
