Infectious mononucleosis, often referred to as “mono,” is a viral illness caused by the Epstein-Barr virus (EBV), which belongs to the herpes virus family. It primarily affects young adults, including college students, and causes symptoms such as fever, sore throat, and body aches. Mono is commonly known as the “kissing disease,” as it’s often transmitted through saliva and other bodily fluids.

If you or someone you know has recently been diagnosed with mono, you might be wondering how long mono lasts. While the duration of mono can vary from person to person, it usually lasts for two to four weeks. The most severe symptoms typically subside within a few weeks, but fatigue can persist for several months. 

In most cases, mono isn’t life-threatening, and getting plenty of rest and hydration is enough to fight the infection. Read on to learn more about mono, how long it lasts, and the stages of the infection. 

How long does mono last?

Mono can last for several weeks. However, some people may experience certain symptoms such as severe tiredness or fatigue for up to six months or longer. The incubation period, or the time from infection to symptoms, is around four to six weeks, which can delay when illness starts and partly explains the wide range in how long mono lasts.

A person can spread EBV for weeks even before severe symptoms. The virus can spread through:

• Sneezing
• Coughing
• Sharing eating utensils
• Kissing
• Sexual contact
• Organ transplants
• Blood transfusions

Recovery time can often depend on factors such as a person’s age, overall health, and daily habits. Getting enough sleep, managing stress effectively, and adhering to a healthy routine can all help a person recover more quickly.

What helps mono go away faster?

There isn’t a medicine that cures mono, so recovery comes down to giving the body time to heal. Rest and drinking plenty of fluids are at the top of the list when it comes to recovering. Over-the-counter (OTC) drugs like Tylenol (acetaminophen) and Advil (ibuprofen) can also help reduce fever, sore throat, and body aches. 

Other ways to help manage mono include the following:

• Gargle with warm salt water or sip tea with honey to ease a sore throat and swollen tonsils
• Use cool compresses to help manage body temperature during a fever and relieve body aches
• Stay away from contact sports or heavy lifting until a healthcare provider says it’s safe
• Avoid certain antibiotics like amoxicillin, which can trigger a rash during mono

If symptoms are bothersome and not improving after a couple of weeks, consult a healthcare provider. They can rule out complications and recommend options for symptom relief.

What are the stages of mono?

Mono can be divided into several stages, including the prodrome, acute, and convalescent stages.

1. Incubation period

During the initial infection, the virus enters the body and starts to multiply, usually within the lining of the mouth or throat. At this stage, individuals typically do not experience any symptoms. However, they can still transmit the virus to others through direct contact, such as kissing, or by sharing personal items like toothbrushes or utensils. This period may last for four to six weeks. 

2. Prodrome stage

During this stage, the virus has already entered the body and continues to multiply. An infected person may not show any symptoms of mono. However, for many people, mild symptoms may start to appear, such as sore throat, body aches, and headaches. This stage usually lasts for three to five days. 

3. Acute phase

The acute phase is when the most common symptoms of mononucleosis become more apparent, including sore throat, extreme fatigue, fever, and swollen lymph nodes in the neck and armpits. During this stage, people may also experience more severe headaches, muscle aches, an enlarged spleen, and a rash. A healthcare provider can confirm mono with blood tests, such as a Monospot test, which looks for specific antibodies. The acute phase generally lasts for two to six weeks.

4. Convalescent stage

This recovery stage occurs when symptoms begin to subside and the body starts to heal. A person might still feel fatigued, and swollen lymph nodes can stick around for some time. However, normal energy levels typically return over a period of three to six months. 

Do I need to isolate if I have mono?

If you have mono, it’s recommended to take appropriate measures to reduce the risk of spreading the infection to others. While complete isolation may not always be necessary, it is advisable to be cautious about contact with others, especially during the acute phase of the illness.

During the first few weeks of infection, it is best to avoid sharing eating utensils, drinking from the same glass, or kissing others. As the spleen could rupture while infected, it’s often recommended to avoid contact sports until a healthcare provider deems it safe to do so.

If you’re around someone with a weakened immune system, it’s best to give them some space while you’re recovering. Even sitting close for a long time or sharing the same air can increase the risk of spreading the virus. 

Mono treatment

Mono often goes away on its own without specific treatment. Some treatment options may help manage symptoms and reduce the severity of the illness. OTC pain relievers and fever reducers can be especially helpful for managing symptoms like fever and sore throat. Additionally, getting plenty of rest, eating nutritious foods rich in antioxidants, and drinking enough fluids can help support the body while fighting the infection.

Antibiotics aren’t given for mono since it’s not a bacterial infection. Although a virus causes mono, no antiviral medications are currently approved to treat it. Some antivirals, such as acyclovir and valacyclovir, may help reduce the replication of the virus but are not universally approved or recommended for mono. 

In rare cases, mono may lead to complications, including inflammation of the lining of the heart (pericarditis), inflammation of the liver (hepatitis), and anemia. However, most recover without serious problems or long-lasting effects.

The bottom line

Mono can leave you feeling drained for weeks or even months. While it’s not usually a serious issue, it requires time and care to recover. Rest, stay hydrated, and avoid spreading the virus to others.
