Glandular fever, also known as 'infectious mononucleosis', is commonly caused by the Epstein Barr Virus (EBV). EBV infects and reproduces in the salivary glands. Direct contact with virus-infected saliva, such as by kissing, can transmit the virus. A person is infectious several days before symptoms appear and for some time after, possibly for months or, rarely, even years. |
