It is a useful tool and germane to today's discussion; thanks!! I note that according to the map the United states has 2.6 million infected (which is low compared to some estimates) Canada; .25 million. Also...more of a question, if one looks at Mexico, one sees 3 genoype 1 groups; 1, 1a and 1b Do we surmise that they are genotype 1, but merely without sub-type?
