Some observations (maybe stating the obvious): https://tools.wmflabs.org/pageviews/#start=2016-01-16&end=2016-02-14&am… the double peak seems to confirm PV count on wp:en is not correlated much with spread of the disease, but of course wp:es is much more relevant https://tools.wmflabs.org/pageviews/#start=2016-01-16&end=2016-02-14&am… As Wikipedia probably isn't much of a household name in some Spanish countries, absolute PV values per country/region are mostly incomparable, even when normalized for population count in the region, and again for percentage people with internet connections (let alone the latter numbers will be unreliable to start with). A detection of highest relative changes week over week could tell us something. (the oldest week in the comparison should have a minimum PV value, or relative changes from almost zero to negigible with stand out as false remarkables. Of course a decline could indicate saturation in information demand, but not per se in number of people affected.

Subject: Re: [Analytics] [Wiki-Medicine] Zika The link to microcephaly has become clearer this week: https://en.wikipedia.org/w/index.php?title=Zika_virus&oldid=704879995#c… states "A complete ZIKV genome sequence [..] was recovered from brain tissue" (of a fetus whose mother had been infected with Zika virus). Given that the mass media are currently all over Zika, simple page view stats are essentially useless for tracking the spread of the disease - the PLOS Computational Biology article that Anthony has linked states "Wikipedia data have a variety of instabilities that need to be understood and compensated for. For example, Wikipedia shares many of the problems of other internet data, such as highly variable interest-driven traffic caused by news reporting and other sources." However, correlating geolocated view stats or searches with external info like http://www.healthmap.org/zika/#timeline might be useful. In addition, if we had some representation of clickstreams for Zika-related articles in languages spoken in affected areas, this could help guide the development of Zika-related content in those languages. Beyond Wikipedia, there is a page on Wikidata to coordinate activities around Zika: https://www.wikidata.org/wiki/Wikidata:WikiProject_Medicine/Zika . Cheers, d.
