B25-B34: Other viral diseases

B27: Infectious mononucleosis

Infectious mononucleosis, commonly called 'mono', is a group of conditions typically caused by the Epstein-Barr virus (EBV). Individuals often get this virus through saliva, which is why it is sometimes referred to as the 'kissing disease'. However, it can also spread through coughs, sneezes, or by sharing eating utensils. Common symptoms include fatigue, sore throat, fever, and swollen lymph nodes. The spleen, located in the upper left part of the abdomen, may also swell in some cases. Most individuals feel better after two to four weeks, but it may take some people several months to recover completely. Keep in mind that even when symptoms decrease, you could still carry the virus and transmit it to others.
