Can Someone Who s Had Mono Catch It Again From Soneone Else
- Most people will non be able to get mono twice in their life.
- That's because one time you're infected with the virus that causes mono, it remains inactive in your body.
- Notwithstanding, those who are immunocompromised may exist at a higher hazard for the virus reactivating, and experiencing mono symptoms more than than once.

Infectious mononucleosis, or mono for short, is spread by the Epstein–Barr virus (EBV), a member of the herpes family unit, through saliva or respiratory droplets.
More than 90% of people worldwide are infected with EBV. The virus volition remain inactive for many of these people, and they'll never have whatever symptoms of mono.
However, at least 25% of young people who get infected with EBV will develop symptoms of mono, according to the Centers for Disease Control and Prevention (CDC). But in that location's some adept news — if yous get mono, information technology's almost impossible to become it again. Here's why.
Can yous become mono twice?
In one case y'all've had mono, information technology's extremely unlikely that you'll go it again months or even years later.
When you lot've been infected with EBV, information technology remains in your pharynx and blood cells for the rest of your life — simply is usually latent, or inactive. Your immune system produces antibodies in your blood that assistance protect you against a recurrence of EBV.
"This will give you lot permanent amnesty from communicable the virus again," says Dimitar Marinov, MD, an banana professor in the section of hygiene and epidemiology at Medical University in Varna, Bulgaria. "That's the reason why yous cannot get mononucleosis twice."
Nonetheless, EBV may periodically reactivate in your torso, leading to college levels of the virus in your saliva. Even if EBV does reactivate, in that location are ordinarily no symptoms of mono in otherwise healthy people, Marinov says.
However, y'all could mayhap still spread EBV to others, regardless of how long information technology's been since you were first infected, the CDC notes. That'due south why mono can exist contagious long after you've displayed symptoms.
People with weak immune systems are more likely to go mono twice
However, if you take a weakened or suppressed immune arrangement, also known as existence immunocompromised, and so yous're more at adventure of getting mono more than once. If you have the following conditions, you are more likely to show symptoms of mono if EBV reactivates.
- People with autoimmune diseases such every bit lupus, multiple sclerosis, or rheumatoid arthritis
- People taking immunosuppressant medications, such as corticosteroids like prednisone, to treat autoimmune diseases
- Cancer patients
- People with AIDS
Although it is unclear what can trigger a reactivation of EBV, it may be due to an activation of B cells — a type of white blood cells in your immune system — in response to an unrelated infection.
EBV invades your B cells and makes your body produce an excessive number of lymphocytes, the round white blood cells in your lymph tissues, and produce fewer neutrophils, the white blood cells that heave your immune organisation's ability to fight infection.
EBV-invaded B cells may proliferate more in people with weakened allowed systems. This makes them more likely than people with healthy immune systems to take astringent symptoms acquired by EBV.
In very rare cases, an EBV infection may develop into chronic active EBV (CAEBV). Instead of going fallow, EBV remains active and can pb to serious complications such as a weakened immune arrangement, lymphomas, or organ failure. The only current cure for CAEBV is hematopoietic (blood cells) stem cell transplantation.
People from Asia, South and Central America, and Mexico are more at risk for CAEBV, and it's mostly caused by genetic factors. "There are people with genetic variations in their immune cells who are more susceptible to a CAEBV infection," Marinov says.
Other common illnesses that y'all might mistake for mono
It'southward rare that you'll really go mono twice. And so, if you've already had mono once, and you recall yous're getting it once again, it'southward more likely that y'all actually have some other illness with similar symptoms, such as strep throat or influenza.
Mono symptoms usually begin four to six weeks subsequently you've been infected with EBV. The symptoms typically last from ii to vi or more weeks, which is much longer than they usually last for other viral infections.
Unlike mono, the mutual influenza is caused by an flu virus that can be transmitted not but through saliva, but through the air and by touching contaminated objects.
Flu symptoms commonly begin suddenly, soon after you get infected, rather than over fourth dimension equally they do with mono. The flu typically lasts from a week to 10 days.
And while mono and the influenza are acquired past viruses, strep throat is caused past group A Streptococcus leaner, so it can exist treated with antibiotics and will commonly final less than ane week.
The bottom line
If you've already had mono, and call back you may have it again, bank check with your doctor, who tin can determine if that's the case — or if you just take another common disease, similar strep pharynx or influenza.
However, in some cases, serious conditions tin can as well display symptoms similar to mono. This includes hepatitis B, a virus that causes inflammation of the liver and has additional symptoms likewise those for mono, such as dark urine and yellowing of your skin. You lot should see a medico right away if you take these symptoms.
