The treatment of streptococcal infections aims to quickly eliminate the pathogens, alleviate symptoms, and prevent complications. Treatment strategies typically combine the use of antibiotics with supportive therapy to inhibit bacterial proliferation and restore the immune system. Physicians will develop individualized plans based on the type of infection (such as pharyngitis or skin infections) and the patient's condition, emphasizing the importance of early diagnosis and regular medication.
The treatment goals include four core objectives: first, to rapidly suppress pathogen growth and prevent the spread of infection; second, to relieve uncomfortable symptoms such as fever and sore throat; third, to reduce transmissibility and avoid community spread; and fourth, to prevent subsequent complications such as nephritis or rheumatic fever. During the treatment process, patients must strictly adhere to medication instructions and cooperate with lifestyle adjustments to enhance efficacy.
Currently, the treatment of streptococcal infections is primarily divided into two categories: pharmacological and non-pharmacological. Pharmacological treatment focuses on antibiotics, especially for Group A Streptococcus (GAS) infections, as antibiotics can directly kill bacteria or inhibit their proliferation. Non-pharmacological treatment emphasizes symptom management and physical recovery, such as antipyretics and rest arrangements. Treatment plans need to be adjusted based on the site of infection, severity, and patient age; for example, certain antibiotics may be avoided in children.
The key to antibiotic treatment is "adequate dosage and complete course," meaning that even if symptoms improve after 24-48 hours, the full course must be completed to avoid antibiotic resistance. Common treatment combinations include oral antibiotics and topical ointments, while severe infections may require intravenous administration. Non-pharmacological therapies include symptom relief measures, such as using saline gargles or cold drinks for sore throats, and keeping skin infections clean to promote healing.
Penicillin-type drugs are the first-line treatment, such as penicillin V or phenoxymethylpenicillin, which work by disrupting bacterial cell wall synthesis. For those allergic to penicillin, cephalosporins or macrolides (such as azithromycin) can be used instead. The treatment duration is typically 10 days; even if symptoms improve within 24-48 hours, the full course must be completed to prevent resistance and complications.
During treatment, attention must be paid to drug interactions and side effects. For example, alcohol should be avoided while taking penicillin, and macrolides may cause gastrointestinal discomfort. Severe infections (such as complicated abscesses) may require hospitalization for intravenous antibiotics, such as penicillin G or vancomycin. Physicians will adjust the medication plan based on the extent of the infection and the patient's allergy history.
Treatment for children must calculate dosages based on weight, and aspirin should be avoided to prevent Reye's syndrome. For pregnant women with infections, penicillin-type drugs are a safe choice, while tetracyclines are limited to those over 18 years of age. Immunocompromised individuals may require extended treatment courses or the combination of other antimicrobial agents to ensure complete eradication of the pathogens.
The challenge of treating antibiotic-resistant streptococci is increasing, so physicians may choose combination antibiotics or conduct bacterial sensitivity tests in suspected resistant cases. Additionally, in cluster infection events, contacts may need to receive prophylactic antibiotics to block transmission.
Non-pharmacological measures can accelerate recovery and reduce symptom discomfort. Symptom relief strategies include using local cold compresses to reduce redness and swelling, saline gargles to soothe sore throats, and analgesics (such as acetaminophen) to control fever. Skin infections require keeping the wound dry and clean, avoiding scratching to prevent secondary infections.
Adjustments during the recovery period can enhance treatment efficacy. Adequate rest allows the immune system to focus on combating the infection, and consuming a high-nutrition diet (such as chicken soup and fruits) can replenish energy. Avoid overusing the throat or damaged skin areas; for example, reducing talking can lessen throat irritation, and avoiding tight clothing can reduce pressure on skin infections.
To prevent reinfection, hygiene habits must be strengthened: wash hands with soap for at least 20 seconds daily, avoid sharing items with infected individuals, and regularly clean frequently touched surfaces. Contacts showing symptoms should seek medical attention immediately, as early treatment can interrupt the transmission chain. In terms of diet, it is recommended to supplement with vitamin C and probiotics to support the immune system and gut health.
The issue of antibiotic resistance has prompted the medical community to develop new treatment strategies. Research includes novel antibiotics targeting bacterial biofilms and using phage therapy to specifically eliminate certain strains. Additionally, for cases of recurrent infections, gene therapy may enhance disease resistance by modulating the host's immune response.
Vaccine development is key for long-term prevention. Currently, a vaccine for Group A Streptococcus is in clinical trials, aiming to induce broad immune protection and reduce community infection rates. Furthermore, artificial intelligence-assisted diagnostic systems can accelerate infection classification, making treatment more precise.
Seek immediate medical attention if the following occurs: fever lasting more than 48 hours without resolution, worsening redness and swelling of the throat, expansion of skin infection, or signs of complications such as joint pain or skin rashes. If symptoms do not improve within 48 hours after treatment or if symptoms recur after completing the antibiotic course, reevaluation is necessary.
Special populations, such as immunocompromised patients, pregnant women who have been in contact with confirmed cases, or individuals with chronic diseases, should proactively discuss prophylactic medication or enhanced monitoring with an infectious disease specialist. If symptoms such as pus formation or lymphadenopathy persist after initial treatment, referral to an infectious disease or dermatology specialist for further examination is required.
Generally, within 24 hours of receiving antibiotic treatment, patients' transmissibility significantly decreases, but the complete course of 7 to 10 days must be finished to avoid bacterial resistance. It is recommended to wait 24 to 48 hours after symptoms have resolved and there is no fever before resuming group activities to reduce the risk of secondary transmission.
Why do doctors recommend completing the full course of antibiotics even if symptoms disappear?Not completing the course may result in bacteria not being completely eradicated, and remaining bacteria may develop resistance, making subsequent treatment more difficult. Additionally, incomplete healing may lead to complications involving the heart or joints, so strict adherence to the physician's instructions to complete all medications is necessary.
After recovering from a streptococcal infection, do household items need special disinfection?Streptococci survive for a short time in the environment and are typically transmitted through contact with droplets or secretions. It is recommended to disinfect frequently touched surfaces with regular household cleaners and to enhance handwashing, but antiviral-grade disinfectants are not necessary. Utensils and toothbrushes used by the infected individual should be replaced or thoroughly cleaned.
Can I eat normally during treatment? Are there any dietary principles to pay special attention to?During treatment, it is advisable to choose soft or liquid foods that are easy to swallow and to avoid spicy, hot, or rough foods that may irritate the throat. It is recommended to increase fluid intake and vitamin C, but specific foods that should not be taken with antibiotics (such as avoiding dairy products with tetracyclines) should be followed according to the pharmacist's instructions.
If symptoms reappear after treatment, does that mean the treatment has failed?Recurring symptoms may be due to secondary infections, incomplete isolation during treatment, or antibiotic-resistant bacteria. A follow-up visit should be scheduled immediately for re-examination; the physician may adjust the type of antibiotics or increase the evaluation for complications, and one should not extend the use of medication on their own.
