CovsirPhy is a Python package for COVID-19 (Coronavirus disease 2019) data analysis with phase-dependent SIR-derived ODE models. We can download datasets and analyse it easily. This will be a helpful tool for data-informed decision making. Please refer to "Method" part of Kaggle Notebook: COVID-19 data with SIR model to understand the methods.
- Data preparation and data visualization
- Phase setting with S-R Trend analysis
- Numerical simulation of ODE models
- Stable: SIR, SIR-D and SIR-F model
- Development: SIR-FV and SEWIR-F model
- Phase-dependent parameter estimation of ODE models
- Scenario analysis: Simulate the number of cases with user-defined parameter values
- (In development): Find the relationship of government response and parameter values
- Monitor the spread of COVID-19
- Keep track parameter values/reproduction number in each country/province
- Find the relationship of reproductive number and measures taken by each country

We have the following options to start analysis with CovsirPhy. Datasets are not included in this package, but we can prepare them with DataLoader
class.
Installation | Dataset preparation | |
---|---|---|
Standard users | pip/pipenv | Automated with DataLoader class |
Developers | git-cloning | Automated with DataLoader class |
Kagglers (local environment) | git-cloning | Kaggle API and Python script and DataLoader |
Kagglers (Kaggle platform) | pip | Kaggle Datasets and DataLoader |
Installation and dataset preparation explains how to install and prepare datasets for all users.
Stable versions of Covsirphy are available at PyPI (The Python Package Index): covsirphy and support Python 3.6 or newer versions.
pip install covsirphy --upgrade
Development versions are in GitHub repository: CovsirPhy.
pip install "git+https://github.com/lisphilar/covid19-sir.git#egg=covsirphy"
Main datasets will be retrieved via COVID-19 Data Hub and the citation is
Guidotti, E., Ardia, D., (2020), "COVID-19 Data Hub", Journal of Open Source Software 5(51):2376, doi: 10.21105/joss.02376.
Quickest tour of CovsirPhy is here. The following codes analyze the records in Japan, but we can change the country name when creating Scenario
class instance for your own analysis.
import covsirphy as cs
# Download datasets
data_loader = cs.DataLoader("input")
jhu_data = data_loader.jhu()
population_data = data_loader.population()
# Check records
snl = cs.Scenario(jhu_data, population_data, country="Japan")
snl.records()
# S-R trend analysis
snl.trend().summary()
# Parameter estimation of SIR-F model
snl.estimate(cs.SIRF)
# History of reproduction number
_ = snl.history(target="Rt")
# History of parameters
_ = snl.history_rate()
_ = snl.history(target="rho")
# Simulation for 30 days
snl.add(days=30)
_ = snl.simulate()
