Overview

Mononucleosis
Infectious mononucleosis, often called mono, is a contagious viral infection. It commonly causes extreme tiredness, fever, sore throat, swollen lymph nodes, and sometimes an enlarged spleen or liver. Most cases are caused by Epstein-Barr virus. Symptoms often develop gradually and most people recover, although fatigue can continue for several weeks or occasionally longer.
Persistent Depressive Disorder
Persistent depressive disorder is a chronic form of depression in which a person has a persistently low or depressed mood over a prolonged period. It was previously called dysthymia. In addition to depressed mood, people may experience low energy, poor concentration, changes in sleep or appetite, low self-esteem, or feelings of hopelessness. Symptoms can interfere with work, relationships, self-care, and daily activities. Some people with persistent depressive disorder also experience episodes of major depression.

Diagnosis

Mononucleosis
Diagnosis is based on the symptoms and physical examination, including examination of the throat and lymph nodes and checking for enlargement of the liver or spleen. A healthcare provider may order blood tests to look for changes associated with mononucleosis or antibodies to Epstein-Barr virus. A rapid mono test may be used in appropriate circumstances, although additional testing may be needed when the result is unclear.
Persistent Depressive Disorder
Diagnosis is based on the history and pattern of depressive symptoms over time. A clinician evaluates mood, sleep, appetite, energy, concentration, self-esteem, hopelessness, functioning, and any associated mental health symptoms. The duration and persistence of symptoms are important because persistent depressive disorder is characterized by a long-standing course. Blood or urine tests may sometimes be used to look for medical conditions that can contribute to depressive symptoms.

Prevention

Mononucleosis
There is no vaccine that prevents infectious mononucleosis. The risk of spreading the infection can be reduced by avoiding kissing and by not sharing food, drinks, utensils, or lip balm with someone who has mono. Good hand hygiene is also useful. Because the virus may remain in saliva after symptoms improve, people should follow appropriate precautions during recovery and according to medical advice.
Persistent Depressive Disorder
There is no guaranteed way to prevent persistent depressive disorder, but early recognition of depressive symptoms and timely professional support may reduce their impact. Maintaining regular sleep, physical activity, healthy nutrition, supportive relationships, and meaningful daily activities can support overall mental health. People with a history of depression can work with their healthcare provider to recognize early signs of worsening and develop a plan for responding to them. Avoiding harmful substance use may also reduce complications.

Risk Factors

Mononucleosis
Mononucleosis is particularly common among teenagers and young adults, although infection can occur at any age. Risk increases with close contact with an infected person because the virus is commonly spread through saliva. Sharing drinks, food, utensils, or personal items that contact saliva can also transmit the infection. Previous lack of exposure to Epstein-Barr virus may make a person susceptible to symptomatic infection.
Persistent Depressive Disorder
Risk may be influenced by family history of depression, previous depressive episodes, prolonged stress, social difficulties, and other mental health or medical conditions. Persistent depressive disorder can occur at different ages, and symptoms may appear differently in children, adolescents, and adults. Older adults may experience additional difficulties with self-care, isolation, or cognitive symptoms. Having another form of depression or a history of significant psychological stress may increase the likelihood of persistent symptoms.
