Mono Throat vs Strep Throat - How to Tell the Difference

Understanding Mono Throat vs Strep Throat

Both mono throat and strep throat can make swallowing difficult and painful. But there are key differences between these two common throat infections. Learning to distinguish mono from strep can help ensure proper diagnosis and treatment.

What is Mono?

Mononucleosis (mono) is an infectious illness caused by the Epstein-Barr virus (EBV). It's sometimes called "the kissing disease" because mono is easily spread through contact with saliva. But you can also get mono through close contact like coughing, sneezing, or sharing drinks or utensils.

Many people are exposed to EBV at some point. Mono symptoms usually show up 4-6 weeks after initial infection. The illness often surfaces in teens and young adults, but you can get mono at any age.

Common Signs of Mono

Mono throat is one of the classic symptoms of infectious mononucleosis along with:

• Fever
• Extreme fatigue
• Swollen lymph nodes in the neck and armpits
• Swollen liver or spleen

Mono throat typically involves some combination of pain, inflammation, and swelling in the back of the throat. Your tonsils may become enlarged and develop a thick white or yellow coating. This is where the term "mono kissing disease" comes from - kissing someone with mono can easily pass along the EBV virus.

How Long Does Mono Throat Last?

Mono throat discomfort often persists for 1-2 weeks. Most mono symptoms go away within 4 weeks. But fatigue can linger for 2-3 months after other signs disappear. Swollen lymph nodes and spleen may take even longer to return to normal size.

Key Features of Strep Throat

Strep throat is another common source of sore throat. It's caused by a Streptococcus bacteria rather than a virus like mono. Strep bacteria are highly contagious and easily passed through mucus and saliva.

Typical Strep Throat Symptoms

The most common signs of a strep throat infection include:

• Pain and difficulty swallowing
• Fever
• Pus on the tonsils
• Bright red throat or tonsils with white patches
• Tiny red spots on the roof of the mouth
• Swollen lymph nodes in the front of the neck
• Headache
• Upset stomach or vomiting

How Long Does Strep Throat Last?

Without treatment, strep throat symptoms typically last 3-7 days. Taking a full course of antibiotics can often knock out the infection in just 1-2 days. This helps prevent potential complications like sinus infections, ear infections, even kidney inflammation or rheumatic fever.

Key Differences Between Mono and Strep

Both mono and strep can lead to considerable throat discomfort. But there are some important distinctions between these two conditions:

Age Differences

Mono frequently arises in teens and young adults while strep throat can occur at any age. Strep may be slightly more common in children age 5-15 but still impacts people of all ages.

Contagious Period

Those with mono are most contagious in the 4-6 weeks before and after mono symptoms appear. In contrast, untreated strep throat is generally contagious for 2-5 days after the illness starts, sometimes up to a couple weeks.

Fatigue Level

Exhaustion and lack of energy are hallmark signs of mono that can last for weeks or months. Strep may trigger mild tiredness but does not lead to the profound fatigue mono often produces.

Treatment Options

While antibiotics can knock out a strep infection, they are not effective against viral mono. Treatment for mono centers on relieving symptoms and giving the body adequate rest.

However, a mono rash caused by an allergic reaction to antibiotics may require antihistamines or steroid treatment. Seek prompt medical care if a rash appears while taking antibiotics for suspected strep throat.

Getting Properly Diagnosed

Distinguishing mono from strep based on throat symptoms alone can be tricky. Throat cultures and blood tests may be needed for an accurate diagnosis:

Throat Swab Culture

A throat swab can detect the presence of streptococcal bacteria and confirm a strep throat infection. Negative swab results help rule out strep as the cause of sore throat.

Mono Blood Tests

Blood tests check for antibodies related to EBV. High antibody levels indicate mono even when throat symptoms are mild. A complete blood count may also show elevated white blood cells and abnormal liver enzymes with mono.

Prompt blood tests and throat cultures help guide appropriate treatment. Be sure to share your full range of symptoms with your healthcare provider.

Caring for Sore Throat at Home

To soothe throat discomfort while awaiting lab results:

• Drink cold beverages or suck on ice chips
• Gargle with salt water
• Use over-the-counter pain relievers like acetaminophen or ibuprofen
• Get extra rest
• Avoid irritants like smoke and strong chemicals

Severe dehydration can occur with mono or strep throat. Be sure to take in adequate fluids. Seek prompt medical help if you have difficulty breathing or swallowing.

Preventing Spread to Others

Practice good hand hygiene and avoid close contact with others when sick. Do not share food, drinks, utensils, towels or toothbrushes when symptoms are present.

With strep infections, continue isolation precautions for at least 24 hours after antibiotics are started. Those with mono should avoid kissing and contact sports for several weeks after symptoms resolve.

Prompt diagnosis and treatment of mono or strep throat reduces contagiousness. But staying home from school or work when actively ill also prevents these bugs from spreading through classrooms, sports teams, offices and other close communities.
