Why Do I Keep Getting Strep Throat in Adults?

Repeated bouts of strep throat can be frustrating for adults. While it’s a common bacterial infection, its recurrence suggests specific underlying factors. Understanding these factors can help address the persistent nature of these infections.

Understanding Recurrent Strep Throat in Adults

Strep throat, caused by the bacterium Streptococcus pyogenes (Group A Streptococcus or GAS), infects the throat and tonsils. Symptoms include a sore throat that comes on quickly, painful swallowing, fever, and sometimes swollen neck lymph nodes. Tonsils may appear red, swollen, or have white patches.

Unlike viral sore throats, strep throat is bacterial and requires antibiotics. Prompt treatment alleviates symptoms and prevents complications like rheumatic fever or kidney inflammation, though these are rare in adults. While more common in children, adults can contract it, especially if around school-aged children.

Recurrent strep throat in adults often indicates specific issues beyond simple re-exposure. This pattern differs from typical childhood cases, where re-exposure in school is a common explanation.

Factors Contributing to Repeated Infections

Incomplete antibiotic treatment is a common reason for recurrence. Individuals may stop medication once symptoms improve, but before the bacteria are fully eradicated. This premature cessation allows remaining bacteria to multiply and cause a rebound infection.

Asymptomatic carriers are another significant factor. These individuals harbor Streptococcus pyogenes without symptoms but can still transmit the bacteria to others through respiratory droplets. If a close contact, such as a family member or coworker, is an untreated carrier, it can lead to repeated exposure and reinfection.

Frequent re-exposure in certain environments also contributes to recurrent infections. The bacteria spread easily through respiratory droplets released during coughing or sneezing, and through direct contact or shared items like utensils. Environments with close contact, such as households with children, schools, or workplaces, can facilitate continuous transmission.

The immune system can also play a role in susceptibility. Individuals with compromised immune systems, chronic illnesses, or high stress levels may find it harder to fight off the bacteria.

Antibiotic resistance in Streptococcus pyogenes is generally uncommon for first-line treatments like penicillin. However, some strains may show resistance to alternative antibiotics, such as macrolides. If the bacteria develop resistance to the prescribed medication, it can lead to treatment failure and recurring symptoms.

Strategies for Preventing Recurrence

A primary strategy for preventing recurrent strep throat is to consistently complete the entire course of prescribed antibiotics, even if symptoms improve quickly. This ensures the complete elimination of the bacteria and reduces the chance of a relapse or the development of antibiotic resistance.

Practicing good hygiene is an effective way to limit bacterial spread. This includes frequent handwashing with soap and water for at least 20 seconds, especially after coughing, sneezing, or before eating. Avoiding the sharing of eating utensils, cups, and other personal items also helps prevent transmission. When coughing or sneezing, cover your mouth and nose with a tissue or your elbow.

Identifying and treating asymptomatic carriers within a household or close contact group can be beneficial, particularly in situations of persistent family spread. While not routinely recommended for all carriers, treatment may be considered if recurrent infections are disrupting a family’s health or if there is a history of specific complications. Replacing toothbrushes after a strep infection, or at least before finishing antibiotics, can also help prevent reinfection.

Maintaining cleanliness in shared environments can reduce bacterial presence. Regularly disinfecting frequently touched surfaces, such as doorknobs, light switches, and phones, helps control the spread of germs. This is particularly important during periods of increased illness.

Supporting overall immune health through healthy lifestyle choices contributes to reducing infection risk. This involves ensuring adequate sleep, consuming a balanced diet rich in fruits and vegetables, engaging in regular physical activity, and managing stress effectively. Staying well-hydrated also helps keep mucous membranes moist, making it more challenging for bacteria to establish an infection.

When to Seek Specialized Medical Advice

If strep throat recurs frequently, it may be time to seek specialized medical advice. Recurrent strep throat is generally defined as experiencing multiple infections within a specific timeframe, such as three to four times in a year, or seven or more times in a single year. The decision to seek further evaluation is also influenced by the impact these infections have on an individual’s quality of life.

A healthcare provider may consider additional interventions if recurrent infections significantly disrupt daily activities, lead to frequent absences from work, or cause considerable discomfort. One such consideration is a tonsillectomy, the surgical removal of the tonsils. This procedure might be recommended for individuals with chronic tonsillitis or persistent strep throat, especially if they are identified as carriers or experience severe complications.

It is important to understand that even after a tonsillectomy, a person can still contract strep throat, as the bacteria can infect other parts of the throat. Consulting with an Ear, Nose, and Throat (ENT) specialist is advisable for a thorough evaluation of persistent issues. This includes discussing the risks and benefits of surgical options or exploring other management strategies. They can provide a tailored approach based on the specific patterns of recurrence and individual health factors.
