What is mono (mononucleosis)?
Mono (also termed mononucleosis or infectious mononucleosis) is a disease caused by the Epstein-Barr virus (EBV). Children are commonly infected with EBV and show few or no symptoms. Older individuals, teenagers, and adults may show symptoms when infected. These consist mainly of fatigue, fever, inflamed throat, and swollen lymph nodes in the neck. Infected people may also have a rash, swollen liver, or enlarged spleen. Most of the symptoms get better within two to four weeks, but some people can be fatigued for several months. The EBV virus can become inactive after infection, and some people reactivate EBV infection even years later.
Is mono contagious?
Mono is contagious from person to person, especially via an infected person's saliva. Other transmission methods include blood, semen, blood transfusions, and organ transplants. Unfortunately, EBV can also be spread by contact with objects like toothbrushes or eating utensils that are contaminated with EBV. Mono can be spread to babies, children, and adults. Individuals who have mono can be contagious without the characteristic symptoms of fever, fatigue, or swollen glands; some people can be contagious during the incubation period when no symptoms are present.
How do I know if I have mono?
Symptoms of EBV infection may include some or most of the following symptoms:
Many diseases produce similar symptoms, so the diagnosis is usually based on the patient's history, physical, and EBV antibody tests (for example, IgG, IgM, and VCA antibody tests, Monospot test, and others). Interpretation of these tests is not always definitive.
How is mono transmitted? What is the incubation period for mono?
Mono (mononucleosis) is spread from person to person. It is usually not spread by airborne droplets (it can be in some instances when saliva is sprayed and then inhaled) but by direct contact with an infected person's saliva. Because of the predominant way mono is spread (saliva), it has been termed the "kissing disease." The incubation period (from time of exposure to EBV to symptom development) is about four to seven weeks, and some people can spread the disease during the incubation period and up to 18 months later. Mono can be spread by blood, semen, and organ transplants. Saliva-contaminated toothbrushes, utensils, and contact with other EBV-contaminated objects may also spread the disease.
When will I know I am cured of mono?
Unfortunately, the term "cured" doesn't relate well to mono (mononucleosis) because, once infected, a person seems to be infected with EBV for life as occasional "reactivation" of the virus does occur even in healthy people who show no symptoms. Most people will never notice the reactivation of EBV, but according to researchers, these reactivated viruses are probably responsible for the occasional outbreaks in individuals who have not been infected with EBV. It's estimated that about 20%-80% of people infected with mononucleosis shed EBV occasionally for many years.
When should I contact a health care professional about mono?
The majority of individuals who get mono do not require treatment by a physician. However, if you have been diagnosed with mono and had treatment at home for seven to 10 days and you still have problems with poor energy levels, body aches, and swollen lymph nodes, you should contact a physician. If you have a severe sore throat that lasts longer than two to three days, you should also contact a physician. You should go to an emergency department if your tonsils become swollen and they interfere with swallowing and/or breathing, or if you have severe pain in the upper abdomen in the left side (possible spleen rupture).

Aches, Pain, FeverAlthough a fever technically is any body temperature above the normal of 98.6 F (37 C), in practice, a person is usually not considered to have a significant fever until the temperature is above 100.4 F (38 C). Fever is part of the body's own disease-fighting arsenal; rising body temperatures apparently are capable of killing off many disease-producing organisms.
Adenoids and TonsilsTonsillitis is a contagious infection with symptoms of bad breath, snoring, congestion, headache, hoarseness, laryngitis, and coughing up blood. Tonsillitis can be caused acute infection of the tonsils, and several types of bacteria or viruses (for example, strep throat or mononucleosis). There are two types of tonsillitis, acute and chronic. Acute tonsillitis lasts from one to two weeks while chronic tonsillitis can last from months to years. Treatment of tonsillitis and adenoids include antibiotics, over-the-counter medications, and home remedies to relieve pain and inflammation, for example, salt water gargle, slippery elm throat lozenges, sipping warm beverages and eating frozen foods (ice cream, popsicles), serrapeptase, papain, and andrographism Some people with chronic tonsillitis may need surgery (tonsillectomy or adenoidectomy).
Amoxicillin (Amoxil, Moxatag, Larotid) is an antibiotic that belongs to a class of antibiotics called penicillins. Common infections that amoxicillin is used to treat include middle ear infections, tonsillitis, laryngitis, bronchitis, pneumonia, skin, gonorrhea, and urinary tract infections.
Common side effects of amoxicillin include nausea, itching, vomiting, confusion, abdominal pain, and easy bruising.
Drug interactions, dosing, storage, and pregnancy and breastfeeding safety should be reviewed prior to taking penicillins.
Dispermox, Trimox, Wymox, Utimox, and Polymox are discontinued brands and are no longer available in the US.
Amoxicillin vs Levaquin
Amoxicillin and Levaquin are antibiotics used to treat various bacterial infections of the throat, lungs, skin, prostate, and bladder. Amoxicillin is a penicillin while Levaquin belongs to a class of antibiotics called fluoroquinolones. Penicillins and fluoroquinolones work differently in killing bacteria. Both drugs have similar side effects, for example, abdominal pain, headache, rash, itching, insomnia, diarrhea, nausea, and vomiting.
Amoxicillin also causes side effects that include easy bruising, heartburn, insomnia, confusion, bleeding, and dizziness.
Levaquin has serious side effects, for example, sun sensitivity, low blood sugar (hypoglycemia), high blood sugar (hyperglycemia), abnormal heart beats, liver problems, C. diff associated diarrhea.
Dosage depends upon the drug and type of infection. Amoxicillin has few drug interactions while Levaquin interacts with certain mineral supplements, nonsteroidal anti-inflammatory drugs (NSAIDs), and blood thinners like warfarin (Coumadin, Jantoven). Neither drug is recommended to take if you are pregnant or breastfeeding.
Enlarged SpleenAn enlarged spleen or splenomegaly, is generally caused by other diseases or conditions such as infections, cancers, blood disorders, or decreased blood flow. Symptoms of an enlarged spleen are often unnoticed. A feeling of fullness after eating a small amount of food and not being able to eat large meals may be a symptom of an enlarged spleen. Treatment for an enlarged spleen depends upon the cause.
Epstein-Barr Virus (EBV)The Epstein-Barr virus (EBV) is a common cause of mononucleosis (viral pharyngitis). Symptoms and signs of an EBV infection include swollen lymph nodes, fever, rash, sore throat, malaise, and a swollen liver and/or spleen. Treatment focuses on reducing the severity of the symptoms and signs. There is no vaccine to prevent EBV infections.
Fatigue can be described in various ways. Sometimes fatigue is described as feeling a lack of energy and motivation (both mental and physical). The causes of fatigue are generally related to a variety of conditions or diseases, for example, anemia, mono, medications, sleep problems, cancer, anxiety, heart disease, and drug abuse.Treatment of fatigue is generally directed toward the condition or disease that is causing the fatigue.
Infectious MononucleosisInfectious mononucleosis is a virus infection in which there is an increase of white blood cells that are mononuclear (with a single nucleus) "Mono" and "kissing disease" are popular terms for this very common illness caused by the Epstein-Barr virus (EBV).

Is Sore Throat Pharyngitis ContagiousThe medical term for a sore throat is pharyngitis. There are many causes of a sore throat such as medications, diseases (GERD, cancer, AIDS), infections (Streptococcus or strep, mononucleosis), allergies, and smoking. Symptoms are a red, swollen throat; fever, and swollen lymph nodes. Treatment for sore throat depends on the cause.
Labyrinthitis (Inner Ear Inflammation)
Labyrinthitis is inflammation of the labyrinth (the part of the ear responsible for balance and hearing). Doctors do not know the exact cause of labyrinthitis; however, they often are associated viral infections of the inner ear. Symptoms of labyrinthitis are ear pain or earache, ear discharge, problems with balance and walking, ringing in the ears, dizziness, nausea, vomiting, and vertigo. Viral infections associated with labyrinthitis are contagious.
Home remedies may help labyrinthitis symptoms and signs. Over-the-counter (OTC) and prescription medication may treat inner ear infections, labyrinthitis symptoms like vertigo and nausea, and help ear pain.
RashThe word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.
Sore Throat (Pharyngitis)
Sore throat (throat pain) usually is described as pain or discomfort in the throat area. A sore throat may be caused by bacterial infections, viral infections, toxins, irritants, trauma, or injury to the throat area. Common symptoms of a sore throat include a fever, cough, runny nose, hoarseness, earaches, sneezing, and body aches. Home remedies for a sore throat include warm soothing liquids and throat lozenges. OTC remedies for a sore throat include OTC pain relievers such as ibuprofen or acetaminophen. Antibiotics may be necessary for some cases of sore throat.
Swollen Lymph NodesLymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly, but may include fever, night sweats, toothache, sore throat, or weight loss. Causes of swollen lymph nodes also vary, but may include cancer, the common cold, mono, chickenox, HIV, and herpes. The treatment of swollen lymph nodes depends upon the cause.
