Yeah, numbers mostly match; I haven't reviewed the patents & patent application publications to see which aspects of these viruses/illnesses they are covering. The CA one is Canada rather than US patent, and there is a 2 missing before the US 0070031450 patent application publication (i.e., should be 20070031450). I usually use patents.google.com , www.freepatentsonline.com , or worldwide.espacenet.com to look up patents and patent application publications.
