Question about Dynamic Graphs of the Nimda worm

The Dynamic Graphs of the Nimda worm at
are interesting. To what degree do the graphs really tell us how many
hosts are infected? Or do they just tell us how many infected hosts
are observed every 15 minutes? I guess what I am asking is, is the
15 minute sample period causing the graph to under report the total
number of infected sites? How likely is it that the CAIDA monitor
will be visited at least once every 15 minutes by an infected system?
No matter what the answer to this question is, I do like the fact
that the trend is down.
