Measles cases at highest point since 2006 as outbreaks continue to spread

What controls are there on this data?

Under an earlier report [1] I posed questions about how the World Health Organisation compiles its measles data [2,3]. Of what we were being told how many cases were merely reported, how many confirmed, how many just projections, how much of the trend was an artefact of looking for cases?

It may be noted that no one replied to me apart from a further polite enquiry from Dr Anand [4]. And now we have another report of what the WHO says [5] but it is information which is currently impossible to assess for the reasons already outlined, and coincidentally in the same year as the WHO named "vaccine hesitancy" as a "threat" to global health [6].
