Professional Context
With a 25% increase in reported cases, hitting the 95% quality assurance benchmark for disease surveillance data within the next 6 weeks is crucial, and Epidemiologists must optimize their workflow to achieve this metric, all while maintaining a time-to-completion rate of under 3 days and an error rate below 2%.

4 Expert PromptsOutbreak Cluster Detection
Given a dataset of 10,000 reported cases of influenza, with variables including age, sex, location, and date of onset, use spatial and temporal analysis to identify clusters of cases that exceed the expected rate by more than 2 standard deviations, and provide a list of the top 5 clusters ranked by likelihood ratio, along with a map visualizing the geographic distribution of these clusters. Assume a Poisson distribution for the underlying rate and account for seasonal trends using a sine-cosine model. Use a 4-week moving window to define the baseline rate.
Vaccine Effectiveness Analysis
Using a cohort study design, analyze the effectiveness of a new COVID-19 vaccine in preventing severe illness, given a dataset of 50,000 vaccinated individuals and 20,000 unvaccinated controls, with variables including age, underlying health conditions, and date of vaccination or symptom onset. Calculate the hazard ratio and 95% confidence interval using a Cox proportional hazards model, adjusting for confounding variables using a propensity score. Provide a forest plot visualizing the results and a table summarizing the model coefficients.
Disease Surveillance Data Quality Audit
Conduct a quality audit of a disease surveillance dataset containing 5,000 records, with variables including case ID, date of report, symptom onset date, and diagnostic test result. Check for missing or duplicate values, invalid or inconsistent data entries, and outliers or anomalies in the distribution of variables. Provide a report detailing the number and percentage of records with errors or inconsistencies, along with recommendations for data cleaning and validation. Use a combination of statistical and machine learning-based methods to detect anomalies, including z-score calculation and isolation forest algorithm.
Real-time Trend Analysis of Emerging Infectious Disease
Monitor and analyze real-time data on an emerging infectious disease outbreak, with a focus on detecting changes in the trend or patterns of transmission. Use a combination of statistical process control methods, including exponential smoothing and regression analysis, to identify anomalies or shifts in the data. Provide a dashboard visualizing the current trend, along with a table summarizing the key metrics, including the 7-day moving average, growth rate, and R-squared value. Update the analysis daily using new data from a variety of sources, including social media, news reports, and official surveillance systems.
