As previously, the graph is based on a sample of retweets containing the hashtags #Zika and #microcephaly. There are, of course, not comprehensive, since they don’t capture tweets in which these terms are used without the hashtag, and also exclude the more recent #Zikavirus hashtag, although for consistency with our previous postings we have retained the same search strings.
