Mononucleosis infection

Infectious mononucleosis, also called "mono" or "kissing disease," can be debilitating for a while but is usually not dangerous in itself.

Several viruses cause mononucleosis. It spreads easily through saliva and other body fluids. Sharing a drinking glass or a spoon, or kissing someone who has the virus – even they show no symptoms – will transmit the disease. It can also be sexually transmitted.

Due to lifestyle, teenagers and young adults seem to be the most susceptible.

Symptoms include tiredness, sore throat, fever, rash, body aches, swelling in the neck and armpits, and sometimes swollen liver and spleen. The symptoms alone are usually enough for the doctor to make a diagnosis.

Because mononucleosis is caused by a virus, antibiotics will not help. Treatment consists of bed rest, fluids, and good nutrition. The patient should still be under a doctor's care due to the risk of secondary infections or damage to the heart, liver, and spleen.

Handwashing, cleanliness, not sharing dishes or drinking glasses, and not having unprotected sex are the best ways to prevent mononucleosis.

Rarity: Common

Top Symptoms: fatigue, headache, loss of appetite, abdominal pain (stomach ache), cough

Urgency: Primary care doctor

Tooth abscess (infection)

A tooth abscess is a collection of infected material (pus) in the center of a tooth. It is due to bacterial infection.

Top Symptoms: severe jaw or tooth pain, swollen jaw, jaw stiffness, tooth pain that gets worse with hot, cold, or sweet beverages, warm and red jaw swelling

Symptoms that always occur with tooth abscess (infection): severe jaw or tooth pain

Urgency: Primary care doctor
