Can "kissing disease" heal on its own?

　　Kissing disease, also known as infectious mononucleosis, is an acute, self-limiting infectious illness caused by the Epstein-Barr virus (EBV). The vast majority of patients with infectious mononucleosis can recover spontaneously. However, if symptoms are severe, natural recovery may not occur easily. If there are any concerns, it is advisable to seek medical consultation promptly.

　　Infectious mononucleosis is self-limiting, and most patients can recover through their own immune defenses. In individuals with a healthy immune system, the body is typically able to quickly recognize and respond to the virus, resulting in milder illness and eventual clearance of the virus within a certain period, usually with symptoms gradually improving within 1 to 3 weeks.

　　However, if the illness is severe or the patient has a weakened immune system, complications such as persistent high fever, liver damage, or difficulty breathing may develop. In such cases, spontaneous recovery is unlikely, and timely medical treatment is necessary.

　　Infants' immune systems are not yet fully developed, making them more susceptible to EBV infection. Parents should take special care to avoid kissing infants on the mouth to prevent virus transmission.
