Features

Decode encoded patient age to any time unit (years, months, etc)
Convert .dbc files to DBF databases or read them into pandas dataframes. DBC files are basically DBFs compressed by a proprietary algorithm.
Read SINAN dbf files returning DataFrames with properly typed columns
Download SINASC data
Download SIH data
Download SIA data
Download SIM data
Download CIHA data
Download SINAN data (only case investigation tables)

Instalation

There are some dependencies which can't be installed through pip, namely libffi. Therefore on an ubuntu system:

sudo apt install libffi-dev

Then you can proceed to

sudo pip install PySUS

Running from a Docker container

If you use windows, or for some other reason is not able to install PySUS on you OS, you can run it from a docker container.

First, clone the Pysus repository:

git clone https://github.com/fccoelho/PySUS.git

then from within the PySUS directory build the container

cd PySUS
docker build -t pysus .

You only have to do this once. On the first time it will take a few minutes. Then you can launch jupyter from the container a just use PySUS:

docker run -p 8888:8888 pysus:latest

Point your browser to http://127.0.0.1:8888 and have fun. Once you are done, you can stop the container with a simple ctrl-c from the terminal you started it or use the following command:

# to find the container ID
docker ps 
docker stop <CONTAINER ID>

Mounting your working directory in the container

If you don't want you work to disappear when you stop the container, you must mount your working directory on the container. In the example below, I am mounting the /home/fccoelho/Downloads/pysus on the /home/jovyan/work directory inside the container. This means that everything that is saved inside the work directory will actually be saved in the /home/fccoelho/Downloads/pysus. Modify according to your needs.

docker run -e NB_USER=fccoelho -e NB_UID=1000 -v /home/fccoelho/Downloads/pysus:/home/jovyan/work -p 8888:8888 pysus:latest

For more options about interacting with your container check jupyter-docker-stacks documentation.

Changing cache directory

You can change the default directory where PySUS stores files downloaded from DataSUS public repository by setting an environment variable called PYSUS_CACHEPATH with the desired location. If the folder does not exist, it will be created on the package's first invocation.

In MacOS or an Unix-based system, run:

export PYSUS_CACHEPATH="/home/me/desired/path/.pysus"

You can also add this line at the end of your ~/.profile or ~/.bashrc files to make this setting persist.

In Windows, you can set a new environment variable by running:

setx PYSUS_CACHEPATH "C:\Users\Me\desired\path\.pysus"

In Docker, just add an extra parameter -e PYSUS_CACHEPATH="/home/me/desired/path/.pysus" when starting the container:

docker run -p 8888:8888 -e PYSUS_CACHEPATH="/home/me/desired/path/.pysus" pysus:latest
