⚠️ Toxic Shock Syndrome (TSS) is NOT restricted to tampon use in menstruating females.
It can occur from even a seemingly minor wound infection, surgical site, or skin/soft-tissue infection in healthy individuals of any age or sex.

🔴 Key warning signs: Hypotension, high fever, diffuse macular erythroderma (sunburn-like rash), vomiting/diarrhoea, myalgias, and later desquamation (palms/soles).
Causative toxin = TSST-1 exotoxin (or staphylococcal enterotoxins) from Staphylococcus aureus, acting as a superantigen causing massive cytokine release.

👉 Spot it early, remove source immediately, and start toxin-suppressing antibiotics + aggressive supportive care. Mortality can exceed 5–10% if delayed.

🦠 Type of Infection	📖 Description	💊 Management (2026 Evidence-Based)
Staphylococcal Skin & Soft-Tissue Infections (SSTI)	Boils (furuncles), carbuncles, impetigo, cellulitis, abscesses, and wound infections. Most common presentation; often community-acquired MRSA in USA. Can progress to deeper infection if untreated.	🧴 Topical: Mupirocin for localized impetigo (IDSA SSTI 2014). 💊 Oral antibiotics: Dicloxacillin or cephalexin (MSSA); clindamycin, TMP-SMX, or doxycycline if MRSA suspected (IDSA MRSA 2011). ✂️ Incision & drainage (I&D): Mainstay for all abscesses >5 cm or fluctuant lesions. 🧼 Hygiene: Daily handwashing, wound care, decolonization (mupirocin nasal + chlorhexidine baths) for recurrent cases.
Staphylococcal Bacteremia	S. aureus in bloodstream → high risk of sepsis, endocarditis, osteomyelitis, septic emboli. MSSA vs MRSA distinction critical (2025 IDSA MSSA Bacteremia Measure Set).	💉 IV antibiotics: Vancomycin or daptomycin (MRSA); nafcillin/oxacillin or cefazolin (MSSA) - β-lactam preferred for MSSA (IDSA 2025 Measures). 🩺 Source control: Remove infected catheters, drain abscesses; echocardiography (TEE preferred) in all cases. 🔄 Monitor: Repeat blood cultures every 48–72 h until negative; treat 2–6 weeks depending on complications.
Staphylococcal Endocarditis	Infection of native or prosthetic heart valves 💔. Common in IV drug users, prosthetic valves, or after bacteremia. High morbidity (20–40% mortality).	💉 IV antibiotics (4–6 weeks): High-dose vancomycin/daptomycin (MRSA); nafcillin/oxacillin (MSSA) (AHA 2015 + ongoing 2026 updates). 🪡 Surgery: Valve replacement/repair if heart failure, large vegetation (>10 mm), abscess, or persistent bacteremia. 💊 Supportive care: Multidisciplinary endocarditis team; treat complications (emboli, heart failure).
Staphylococcal Osteomyelitis	Bone infection via haematogenous spread or direct inoculation (trauma/surgery). Can become chronic with sequestra if not fully debrided.	💉 IV antibiotics (4–6 weeks minimum): Vancomycin/daptomycin (MRSA); nafcillin/cefazolin (MSSA) (IDSA MRSA 2011 & paediatric AHO 2021). 🪚 Surgical debridement: Essential - remove necrotic bone and hardware. 💊 Chronic cases: Long-term oral suppression (e.g., TMP-SMX + rifampin) after initial IV course.
Staphylococcal Toxic Shock Syndrome (TSS)	Rare but life-threatening toxin-mediated illness. Classic tampon association, but also post-surgical wounds, skin infections, or nasal packing. Superantigen-driven cytokine storm.	💉 IV antibiotics: Clindamycin (toxin suppression) + vancomycin/nafcillin (IDSA & CDC recommendations). 💧 Supportive care: Aggressive IV fluids, vasopressors, ICU monitoring for multi-organ failure. ⚔️ Source control: Immediate removal of tampon/foreign body + surgical debridement of any infected site.
Staphylococcal Food Poisoning	Caused by preformed heat-stable enterotoxins (A–E). Rapid onset (1–6 hours): severe nausea, vomiting, diarrhoea. Self-limited; no fever or systemic signs.	🥤 Supportive only: Oral or IV rehydration and electrolyte replacement. 🚫 No antibiotics: Toxin-mediated, not active bacterial infection. 🥗 Prevention: Proper food refrigeration (<4°C), hand hygiene, avoid cross-contamination.
