Covid Severity Forecasting

Data and models (updated daily) for forecasting COVID-19 severity for individual counties and hospitals in the US. The data includes confirmed cases/deaths, demographics, risk factors, social distancing data, and much more.

Overview

Note: This repo is actively maintained - for any questions, please file an issue.

  • Data (updated daily): We have cleaned, merged, and documented a large corpus of hospital- and county-level data from a variety of public sources to aid data science efforts to combat COVID-19.
    • At the hospital level, the data include the location of the hospital, the number of ICU beds, the total number of employees, the hospital type, and contact information
    • At the county level, our data include socioeconomic factors, social distancing scores, and COVID-19 cases/deaths from USA Facts and NYT
    • Easily downloadable as processed csv or full pipeline
    • Extensive documentation available here
  • Paper link: "Curating a COVID-19 data repository and forecasting county-level death counts in the United States"
  • Project website: http://covidseverity.com/
  • Modeling: Using this data, we have developed a short-term (3-5 days) forecasting model for mortality at the county level. This model combines a county-specific exponential growth model and a shared exponential growth model through a weighted average, where the weights depend on past prediction accuracy.
  • Severity index: The Covid pandemic severity index (CPSI) is designed to help aid the distribution of medical resources to hospitals. It takes on three values (3: High, 2: Medium, 1: Low), indicating the severity of the covid-19 outbreak for a hospital on a certain day. It is calculated in three steps.
    1. county-level predictions for number of deaths are modeled
    2. county-level predictions are allocated to hospitals within counties proportional the their total number of employees
    3. final value is decided by thresholding the number of cumulative predicted deaths for a hospital (=current recorded deaths + predicted future deaths)

Quickstart with the data + models

Can download, load, and merge the data via: ```python import load_data

first time it runs, downloads and caches the data

df = loaddata.loadcountylevel(datadir='/path/to/data') ```

  • for more data details, see ./data/readme.md
  • see also the quickstart notebook
  • we are constantly monitoring and adding new data sources (+ relevant data news here)
  • output from running the daily updates is stored here

To get deaths predictions for our current best-performing model, the simplest way is to call the

add_preds
function (for more details, see ./modeling/readme.md)
from modeling.fit_and_predict import add_preds
df = add_preds(df, NUM_DAYS_LIST=[1, 3, 5]) # adds keys like "Predicted Deaths 1-day", "Predicted Deaths 3-day"
# NUM_DAYS_LIST is list of number of days in the future to predict
