Understanding the distinction is critical for tracking outbreaks and guiding public health action. R0 (Basic Reproduction Number): The Potential R0 is the average number of secondary infections one infected person would cause in a fully susceptible population, with no immunity and no interventions in place. It's a theoretical baseline — a measure of a pathogen's inherent transmissibility under ideal conditions for spread.https://ahmed-azeez.github.io/2025/05/16/diagnostic-tests/Fri, 16 May 2025 00:00:00 +0000https://ahmed-azeez.github.io/2025/05/16/diagnostic-tests/Before you run a single regression or ANOVA, there is a step that separates rigorous analysis from shaky conclusions: diagnostic testing. Think of it as a pre-flight checklist for your data. Skip it, and you risk landing in entirely the wrong place. Why Diagnostics Matter Most statistical methods rest on assumptions — about how data are distributed, how variables relate to one another, and how errors behave. When those assumptions break down silently, the model keeps running and happily produces numbers that mean very little.https://ahmed-azeez.github.io/2024/02/10/public-health-ethics/Sat, 10 Feb 2024 00:00:00 +0000https://ahmed-azeez.github.io/2024/02/10/public-health-ethics/What is Ethics?

Ethics are the set of rules that govern our expectations of our own and others' behavior. The term 'ethics' is derived from the Greek word ethos that can mean custom, tradition, personality or disposition.https://ahmed-azeez.github.io/2024/01/15/epi-outbreak/Mon, 15 Jan 2024 00:00:00 +0000https://ahmed-azeez.github.io/2024/01/15/epi-outbreak/Introduction Data Exploration Feature Engineering Cleaning Data Clustering data Predicting Outbreak Severity Introduction Early detection and classification of infectious disease outbreaks is one of the most consequential challenges in public health. Syndromic surveillance systems collect weekly data on case counts, fatality rates, vaccination coverage, and environmental conditions — yet translating this information into actionable severity classifications remains difficult. In this project, I apply supervised machine learning to a multi-district epidemiological surveillance dataset to predict outbreak severity level: Mild, Moderate, or Severe.
