Hello, Welcome to HCM, Infectious mononucleosis is also called as kissing disease and glandular fever which is caused by the Epstein-Barr virus (EBV). Infectious mononucleosis is a contagious illness and the infection can be spread by saliva and the incubation period is four to eight weeks. This can be diagnosed by blood tests. People who have this disease continue to shed virus particles in their saliva throughout their lifetime. This can be best treated with antibiotics like penicillin or erythromycin and NSAIDS can be given for fever, headache and body ache. Thank you.
