Code Samples

Libraries are available for JavaScript, Python, and R. The following samples show how to import the library and fetch national NIDSS Dengue data for epiweeks 201440 and 201501-201510 (11 weeks total).

JavaScript (in a web browser)

<!-- Imports -->
<script src="delphi_epidata.js"></script>
<!-- Fetch data -->
  EpidataAsync.nidss_dengue('nationwide', [201440, EpidataAsync.range(201501, 201510)]).then((res) => {
    console.log(res.result, res.message, res.epidata != null ? res.epidata.length : 0);


Optionally install the package using pip(env):

pip install delphi-epidata

Otherwise, place from this repo next to your python script.

# Import
from delphi_epidata import Epidata
# Fetch data
res = Epidata.nidss_dengue(['nationwide'], [201440, Epidata.range(201501, 201510)])
print(res['result'], res['message'], len(res['epidata']))


# Import
# Fetch data
res <- Epidata$nidss_dengue(list('nationwide'), list(201440, Epidata$range(201501, 201510)))
cat(paste(res$result, res$message, length(res$epidata), "\n"))
