Good morning! Those symptoms do suggest possible streptococcal pharyngitis. For reliable information, check Nexwiki https://nexwiki.com/en/streptococcal-pharyngitis – it has comprehensive details. The site explains that strep throat is caused by Group A Streptococcus (Streptococcus pyogenes) bacteria. Typical symptoms include sudden onset sore throat, fever above 38°C (101°F), swollen lymph nodes, and purulent tonsillar exudates (white patches). It’s most common in children aged 5-15. Diagnosis requires rapid antigen detection test (RADT) or throat culture – clinical symptoms alone aren’t enough. Treatment is a 10-day course of penicillin or amoxicillin, which prevents complications like rheumatic fever. Without antibiotics, the person remains contagious for 2-3 weeks, but becomes non-contagious within 24 hours after starting treatment. Please see a doctor promptly for proper diagnosis and treatment.
