About GNU Health Patchsets

We provide "patchsets" to stable releases. Patchsets allow applying bug fixes and updates on production systems. Always try to keep your
production system up-to-date with the latest patches.

Patches and Patchsets maximize uptime for production systems, and keep your system updated, without the need to do a whole installation.

NOTE: Patchsets are applied on previously installed systems only. For new, fresh installations, download and install the whole tarball (ie, gnuhealth-3.6.4.tar.gz)

Updating your system with the GNU Health control Center

Starting GNU Health 3.x series, you can do automatic updates on the GNU Health HMIS kernel and modules using the GNU Health control center program.

Please refer to the administration manual section ( )

The GNU Health control center works on standard installations (those done following the installation manual on wikibooks). Don't use it if you use an alternative method or if your distribution does not follow the GNU Health packaging guidelines.

Summary of this patchset

GNU Health 3.6.4 includes:
The most relevant features on this version are:

  • health_contact_tracing package: Allows to trace people that have been in contact with a person suspected of being positive of a infectious disease. Name, demographics, place and date of contact, sanitary region (operational sector), type of contact, exposure risk and follow-up status are some of the information that is recorded per contact.

  • Epidemiological Surveillance: A new report that provides epidemiological information on an specific health condition. Data on prevalence of the disease as well as the incidence over a period of time. It produces epi curves for new confirmed cases, deaths related to the disease (both immediate cause as well as underlying conditions) from death certificates. It also shows very relevant charts on the population affected from a demographic and socioeconomic point of view (age, gender, ethnicity, socioeconomic status).

  • Lab and lab crypto packages: When a disease is confirmed from a positive lab test result, GNU Health LIMS automatically includes the health condition in the patient medical history upon the validation of the lab manager.

  • GH Control center and gnuhealth-setup have been updated.
