How Can You Get Strep Throat?

Strep throat is a common infection, particularly among children, but how exactly do you catch it? Understanding how strep throat spreads is key to prevention and staying healthy. This article will explain the ways you can get strep throat, its symptoms, and what you should know to protect yourself and others.

Understanding Strep Throat

Strep throat is a bacterial infection of the throat and tonsils. It’s caused by group A Streptococcus bacteria, often referred to as group A strep. While most sore throats are caused by viruses, strep throat is specifically bacterial and requires different management.

It’s important to know that strep throat is quite common, especially in certain age groups. Approximately 3 in 10 children and 1 in 10 adults with a sore throat actually have strep throat. This highlights that while sore throats are frequent, strep throat is a significant portion of them, especially in kids.

How Strep Throat Spreads: Catching the Bacteria

Strep throat is contagious, meaning it spreads from person to person. The primary way to get strep throat is through direct contact with respiratory droplets from someone who is infected. These droplets are released when an infected person coughs, sneezes, or talks.

Here are the main ways strep throat is transmitted:

Close Contact with Infected Individuals: This is the most common way strep throat spreads. When someone with strep throat coughs or sneezes, they release tiny droplets containing the bacteria into the air. If you are close to them, you can inhale these droplets and become infected. This is particularly common in households where one family member gets strep throat, as the bacteria easily spreads to others living in the same space.
Sharing Food and Drinks: Sharing utensils, cups, or food with someone who has strep throat can also transmit the bacteria. If an infected person’s saliva is on a fork or glass, and you use the same item, you can ingest the bacteria.
Touching Contaminated Surfaces: While less common than droplet transmission, it’s possible to get strep throat by touching surfaces contaminated with the bacteria and then touching your mouth or nose. The bacteria can survive for a short time on surfaces like doorknobs, toys, or countertops.
Direct Contact with Sores: Although strep throat primarily affects the throat, group A strep bacteria can also cause skin infections. Direct contact with sores or wounds infected with group A strep could potentially lead to strep throat if the bacteria are then introduced to your mouth or nose.

Risk Factors That Increase Your Exposure

While anyone can get strep throat, certain factors increase your risk of exposure and infection:

Age: Strep throat is most common in children between 5 and 15 years old. It is less common in children younger than 3 years old. This age group is often in close proximity at school and daycare, facilitating the spread of infection.
Contact with Children: Adults who are parents of school-aged children or who work with children, such as teachers and daycare providers, are at a higher risk of getting strep throat. This is due to increased exposure to children who are more likely to carry and spread the bacteria.
Crowded Settings: Group A strep bacteria can spread more easily in crowded environments. Places like daycare centers, schools, military training facilities, correctional facilities, and homeless shelters can see higher rates of strep throat due to the close proximity of many individuals.

Recognizing Strep Throat: Symptoms to Watch For

Symptoms of strep throat usually appear 2 to 5 days after exposure to the bacteria. Knowing the symptoms is important for early detection and treatment.

Common Symptoms:

Sore throat that starts quickly: Strep throat often comes on rapidly and can be quite painful.
Pain when swallowing: Swallowing can become difficult and painful due to the inflammation in the throat.
Red and swollen tonsils: The tonsils may appear red and enlarged.
White patches or streaks of pus on the tonsils: This is a classic sign of strep throat.
Tiny, red spots on the roof of the mouth (petechiae): These small red spots can appear on the soft palate.
Fever: An elevated temperature is a common symptom of infection.
Swollen lymph nodes in the front of the neck: The glands in your neck may become tender and swollen.

Less Common Symptoms:

These symptoms are more frequently seen in children:

Headache
Stomach pain
Nausea or vomiting
Rash (scarlet fever): A fine, red rash that feels like sandpaper can sometimes accompany strep throat.

Potential Complications of Strep Throat

If left untreated, strep throat can lead to more serious complications as the bacteria can spread to other parts of the body. These complications can include:

Abscesses: Pockets of pus can form around the tonsils or in the neck.
Ear infections
Sinus infections
Rheumatic fever: A serious condition that can damage the heart, joints, brain, and skin.
Post-streptococcal glomerulonephritis: A kidney disease.

Prevention Strategies: How to Avoid Getting Strep Throat

Preventing strep throat primarily involves practicing good hygiene to minimize the spread of bacteria:

Wash your hands frequently: Wash your hands thoroughly with soap and water for at least 20 seconds, especially after coughing, sneezing, or being in public places.
Cover your mouth and nose when you cough or sneeze: Use a tissue to cover your mouth and nose, and then dispose of the tissue properly. If a tissue isn’t available, cough or sneeze into your elbow, not your hands.
Avoid sharing personal items: Do not share drinks, food, utensils, towels, or handkerchiefs with others, especially when someone is sick.
Stay away from people who are sick: If possible, limit close contact with individuals who have strep throat or other respiratory infections.
Clean and disinfect surfaces: Regularly clean and disinfect frequently touched surfaces like doorknobs, light switches, and phones, especially in shared spaces.

Diagnosis and Treatment

If you suspect you have strep throat, it’s important to see a healthcare provider for diagnosis. They can perform a rapid strep test or a throat culture to determine if you have a strep infection.

Strep throat is treated with antibiotics. Antibiotics help to kill the bacteria, reduce the duration and severity of symptoms, prevent complications, and reduce the spread of infection to others. It’s crucial to complete the full course of antibiotics prescribed by your doctor, even if you start feeling better, to ensure the infection is completely eradicated.

Strep Throat vs. Viral Sore Throat

It’s important to differentiate strep throat from viral sore throats, as they require different approaches. Viral sore throats are more common and often accompanied by symptoms like:

Cough
Runny nose
Hoarseness
Conjunctivitis (pink eye)

If you experience these symptoms along with a sore throat, it’s more likely to be a viral infection. However, it’s always best to consult a healthcare professional for accurate diagnosis and guidance.

In Conclusion

Getting strep throat happens through close contact with the bacteria, mainly via respiratory droplets. By understanding how it spreads and practicing good hygiene, you can significantly reduce your risk. If you suspect you or your child has strep throat, seek medical advice for proper diagnosis and treatment to prevent complications and ensure a speedy recovery.
