Infectious Mononucleosis (“kissing disease”) in teenagers: Is it preventable?
There are a few viruses that can be spread through kissing, with a common one being the Epstein-Barr virus (EBV). EBV more often than not leads to infectious mononucleosis, or mono, which refers to a group of symptoms specifically caused by the virus.
Key Takeaways
- Mononucleosis (the "kissing disease") is usually caused by the Epstein-Barr virus (EBV) and spreads mainly through saliva.
- Beyond kissing, EBV can spread through saliva shared via food, drinks, utensils or personal items.
- It is common in teenagers and young adults; at least 1 in 4 who contract EBV develop mono.
- Symptoms usually surface 4 to 6 weeks after infection, developing slowly rather than all at once.
- Most people develop mono only once, although EBV remains dormant in the body.
What are the symptoms of kissing disease in teenagers?
Most symptoms of infectious mononucleosis usually surface 4-6 weeks after you get infected with EBV. They may develop slowly and not all will occur at the same time.
- Fatigue
- Fever
- Sore throat
- Muscle weakness
- Body aches and headaches
- Swollen lymph nodes in the neck and armpit
- Rashes consisting of pink or purple spots on your skin or in your mouth
Occasionally in severe cases, your liver or spleen may also swell, but mononucleosis is rarely fatal. For some people, their liver or spleen or even both may remain swollen even after their fatigue ends. Most cases of mononucleosis are mild and resolve in 2-4 weeks. However, some people may still feel fatigued for another month or so and occasionally the symptoms can last 6 months or longer.
Can I get mononucleosis from kissing?
Infectious mononucleosis is usually caused by EBV, which is spread through direct contact with saliva from an infected person’s mouth, which explains the nickname “kissing disease”. It can also be spread through coughing or sneezing or sharing food and drinks and personal items with an infected person.
Mononucleosis can also be spread through sexual intercourse and blood transfusions, although this is a lot less common.
Am I at risk of infectious mononucleosis?
Anyone can get mono since it’s a condition spreadable by saliva contact, but if you fall into the following groups, you have a higher risk:
- Aged 15-30
- Students
- Nurses, caregivers and/or anyone who works in healthcare
- People on medication that suppress the immune system
The above are just common examples but generally, anyone who comes into close contact with large groups of people regularly are at an increased risk for mono — which explains why students are considered an at-risk group.
How to know if I have kissing disease: Help from an ENT specialist
Initial exam
Infectious mononucleosis is usually easily diagnosed based on symptoms and other factors — are you 15-25 years of age? Have you been in contact with anyone who has mono? Are you experiencing fever, sore throat and swollen glands? Besides taking your temperature, the ENT specialist in Singapore will also do a physical test and check your neck, armpits and groin and your upper left stomach to see if your spleen is enlarged.
Blood work
While lab tests are usually not necessary to diagnose mono, specific tests like blood work may be done to determine how severe your illness is and identify the cause of your illness.
Patients who have mono due to EBV typically show:
- High white blood cell count
- Unusual looking white blood cells
- Fewer than normal platelets
- Abnormal liver function
There is no specific treatment for mono as symptoms usually resolve on their own, but patients are usually advised to take medication for pain and fever or prescribed corticosteroids to reduce tonsil and throat swelling.
