Chennai's northeast monsoon (November to January) brings 60% of the city's annual rainfall in two months, causing severe flooding in Velachery, Tambaram, Chromepet, Perambur, and Saidapet. Post-monsoon dengue, typhoid, and leptospirosis surges are a consistent annual pattern. blood culture and sensitivity is used when doctors suspect a bloodstream infection, often as part of sepsis workup or infectious disease evaluation. It is ordered for symptoms like high fever, chills, low blood pressure, fast heart rate, or unexplained severe illness.
