Major id conditions
Sepsis
Sepsis (Sepsis-3): life-threatening organ dysfunction from dysregulated host response to infection (SOFA score ≥2). Sepsis Hour-1 Bundle: blood cultures, lactate, fluids, antibiotics, vasopressors if needed.
Septic Shock
Septic shock: sepsis + vasopressor requirement to maintain MAP ≥65 mmHg + serum lactate >2 mmol/L despite adequate fluid resuscitation. Mortality ~40%. Norepinephrine is first-line vasopressor.
MRSA
MRSA (Methicillin-Resistant S. aureus): CA-MRSA (community — SSTIs) vs HA-MRSA (healthcare — bacteremia, pneumonia, device infections). Contact precautions mandatory. Vancomycin is standard treatment.
COVID-19
COVID-19 (SARS-CoV-2): respiratory illness ranging from mild (80%) to critical (5%). Risk: age, obesity, immunocompromise, DM, CVD. Antivirals and anti-inflammatories have improved outcomes significantly.
HIV/AIDS
HIV infection destroys CD4+ T cells. AIDS: CD4 <200 or AIDS-defining illness. ART (antiretroviral therapy) achieves viral suppression. U=U: Undetectable = Untransmittable. PrEP prevents HIV acquisition.
