Everything you need to know about the data
We strongly believe not only in making data open, but also in making it useful to other people.
To that end, we've done our best to document where these data come from, what they mean, and any known limitations about how they should be used.

Where do our data come from?
The majority of our data is provided to CViSB through a partnership with the Kenema Government hospital (KGH) in Sierra Leone. KGH is home to Sierra Leone's only Lassa fever isolation ward, which was used during the 2014-2016 West African Ebola outbreak to treat Ebola as well. Read more about the isolation ward in the height of the Ebola outbreak .
Building off of schema.org's data models, we created schema to organize and standardize our patient, sample, dataset, experiment, and other related data.
... will be coming soon. In the meantime, peruse our schema, which contain information about how we define variables in our datasets.
Patients are grouped into four cohorts: Ebola, Lassa, Control, or Unknown. People in the Ebola or Lassa group are not necessarily infected with the virus. Rather, they are either patients suspected of infection (pending diagnostic confirmation), or contacts of these patients who have suspected exposure to the virus. For specific analyses, you will need to decide how to define the cohort.
Patients are grouped into five outcomes: survivor, dead, contact, control, or unknown.
- Survivors are patients who were alive at least 10 days after presenting at a treatment center.
- Dead are patients who have a confirmed death related to the virus.
- Contacts are people who have been exposed to a patient infected with a virus.
- Controls are healthy people who show no symptoms of infection.
- Unknowns are people whose status is not known 10 or more days after presentation.
Please note that this data is still based on work in progress and should be considered preliminary. If you intend to include any of these data in publications, please let us know – otherwise please feel free to download and use without restrictions. We have shared this data with the hope that people will download and use it, as well as scrutinize it so we can improve our methods and analyses. Please contact us if you have any questions or comments.
