The diagnosis of mono is suspected by the doctor based on the above symptoms and signs. More specific blood tests, such as the monospot and heterophile antibody tests, can confirm the diagnosis of mono. These tests rely on the body's immune system to make measurable antibodies against the EBV. Infectious mononucleosis, also called “mono, ” is a contagious disease. Epstein-Barr virus (EBV) is the most common cause of infectious mononucleosis, but other viruses can also cause this disease. Epstein-Barr Virus and Infectious Mononucleosis Epstein-Barr virus, or EBV, is one of the most common human viruses in the world. It spreads primarily through saliva. Mono caused by EBV is most common among teens and adults. Tests for antibodies to Epstein-Barr viral capsid antigen or Epstein-Barr nuclear antigen are the most sensitive, are highly specific, and are also the most expensive for diagnosing infectious mononucleosis (strength of recommendation [SOR]: C, based on validating cohort study). This is called the incubation period. Once your symptoms do appear, they may last for two to four weeks. You can pass the virus to other people through your saliva for up to three months after your symptoms subside. Some studies have reported that you may still be contagious for up to 18 months.

Less commonly, viral infections such as mononucleosis or cytomegalovirus can cause hepatitis. There are 2 main kinds of hepatitis: acute hepatitis (short-lived) and chronic hepatitis (lasting at least 6 months). When the inflammation doesn't go away in 6 months, the person has chronic hepatitis.

Infectious mononucleosis, "mono, " "kissing disease, " and glandular fever are all terms popularly used for the very common infection typically caused by the Epstein-Barr virus (EBV), but other viruses can also cause the disease.

Even though it's called the kissing disease, there are other ways you can get mono. They usually involve contact with saliva (spit). So sharing straws, toothbrushes, or food from the same plate can spread mono. At first, people don't feel sick after getting infected with the EBV virus.

Mono is contagious. It spreads from person to person through contact with saliva (spit). It's nicknamed "the kissing disease" because it can spread through kissing. Mono can also spread through sexual intercourse and blood transfusions, but this is much less common.

Anemia, a ruptured spleen, and liver problems are all complications that can result from mononucleosis. Sometimes they can be very serious. When teens and adults get mononucleosis, they can experience debilitating symptoms such as extreme exhaustion, muscle aches, and sore throat.

It can take four to six weeks after exposure to feel symptoms, so you may never know whose saliva (or which beer-pong cup) is to blame. Healthy again? Wait at least four to kiss anyone.

Once you have had mono, it is extremely unlikely that you will get it again unless you have a serious problem with your immune system. The basic blood test for mono can stay positive for a year or longer, even after you have fully recovered from mono.

Mono isn't usually a serious illness, but you can have complications that make it more dangerous. The symptoms of mono can range from mild to severe. You may not be able to take part in your normal daily activities for several weeks.

A lot of doctors will do blood tests to confirm mono, though. If someone has symptoms of mono, the doctor may order a complete blood count to look at the lymphocytes, a type of white blood cell that shows specific changes when a person has mono. A doctor may also order a blood test called a monospot.

If you have mono, your CBC will typically show an elevated white blood count (WBC) with more lymphocytes than usual, which is known as lymphocytosis. These lymphocytes will also have an atypical appearance when the medical technologist examines the blood under the microscope.

While the mono itself is not affected by antibiotics, these secondary bacterial infections can be treated with them. Your doctor probably won't prescribe amoxicillin or penicillin-type medications when you have mono. They can cause a rash, a known side effect of these drugs.

Your doctor may also take a sample of blood to check for abnormal white blood cells. This blood test checks for Epstein Barr virus. Doctors usually don't need EBV test results to diagnose mono. But it can help them find out if the Epstein Barr virus is to blame.

Epstein-Barr virus (EBV) is a herpes virus that's spread through saliva. EBV infection increases the risk of Burkitt lymphoma, some types of Hodgkin's and non-Hodgkin's lymphoma and stomach cancer.

The incubation period for an Epstein-Barr virus infection is about four to seven weeks. The symptoms and signs of an EBV infection may include malaise, fever, muscle aches, headaches, sore throat, lymph node swelling, liver swelling, rash, and spleen swelling.
