What causes Mono?

Mono is caused by a specific virus called the Epstein-Barr virus. Its mode of transmission is probably by saliva. The virus is not highly contagious so roommates or family members are unlikely to develop Mono unless there is close contact.

The incubation period (time from contact with the virus until sickness begins) averages 25 days. Once an individual has Mono, generally there is permanent protection against having Mono again

What symptoms may I have?

The most common features include fever, sore throat,and tender swollen glands. Fatigue is prominent and there may be a rash or vague upper abdominal pain (the result of an inflammed liver or spleen). Any combination may exist.

How does my physician know I have Mono?

Diagnosis depends on symptoms and observations on actual examination. Confirmation is based on positive blood tests. It may take a week or longer after you develop a fever before your blood test becomes positive.  There are two blood tests that can confirm a diagnosis of mono. A mono spot test tests for antibodies to the mono virus. Results are available quickly (usually in 24 hrs but there is a possibility of a false negative as there is a limited window period to test for the antibodies.) A second more specific test can check for the actual virus causing mono but this test can take 2 - 3 weeks for results. The doctor will decide which test is indicated based on your symptoms.

How long will I be sick?

It is very unpredictable. It will depend on the severity of the disease that may vary with individuals. If you have fever, sore throat, fatigue, or other problems, it may be necessary for you to be in bed. With good care, you should be up and around in 1 - 2 weeks. Generally speaking, the healthier your lifestyle, the shorter the duration of the illness.

It is advisable to get plenty of rest in the early stages of the disease. Your rate of recovery will depend on your psychological state. Strongly motivated persons will probably return to their normal activity more rapidly than depressed persons.

Fatigue is another matter. A few people have little to no fatigue. Others may be tired for 1 - 4 weeks gradually recovering their full strength and energy. Fatigue is NOT the cause of Mono, but the result.

When your liver or spleen is enlarged, you must be careful not to allow any blow to the chest or abdomen as this may cause damage to these organs.

Can Mono be cured?

Mono can be TREATED, not cured. Increased rest, and an analgesic to decrease the fever and muscle aches are the traditional methods of treating Mono. Some cases of Mono are complicated by streptococcal throat infections and may require antibiotic treatment.

When may I kiss?

This is a difficult question to answer. It is advisable to at least refrain from kissing while there are active symptoms present, i.e. sore throat, fever, swollen glands. Mono may be contracted form carriers (someone who has the organism causing the disease but who is not ill).

Should I drink alcohol?

While you are ill, your physician may advise you not to consume alcohol. Once you are well, you have no special susceptibility to alcohol’ s effects.

What do I do if I think I have Mono?

If symptoms described here make you suspect that you have Mono, don’t panic or self-diagnose. Seek a diagnosis through the University Health Services or your family physician.
