WHO has a form for member states to report individual confirmed COVID-19 cases in countries where the virus is not yet widely circulating. From the WHO guidelines:
WHO requests that national authorities report probable and confirmed cases of COVID-19 infection within 48 hours of identification, by providing the minimum data set outlined in the “Revised case reporting form for 2019 Novel Coronavirus of confirmed and probable cases” through the National Focal Point and the Regional Contact Point for International Health Regulations at the appropriate WHO regional office.
This form can also be useful for local reporting or as an example for other contexts. @seadowg and I have built a downloadable WHO COVID-19 confirmed case report XLSForm that anyone can use and leave feedback on.
The field names match WHO’s data dictionary.
The original paper form is broken into two ODK forms to be filled in at different times and linked on the case identifier.
If there is interest, I can share a process for using Excel to join data between the two forms and put it into the provided template for line listing.
