All three HA sequences (A/Mexico/InDRE1946/2011 and A/Mexico/InDRE1947/2011) are closely related to each other and have S165N and A189T, which is also found in recent (2011) isolates in the US. Earlier sequences with these markers were circulating in Galicia, Spain a year ago. The sequence from the fatal case also has D225N, which is a change associated with Ukraine and Russian fatalities in 2009 (and was frequently found in association with D225G). It is likely that this emerging sub-clade is present throughout Mexico and Venezuela, but only the three sequence from Chihuahua have been released thus far. More sequences from severe and fatal cases in Mexico and Venezuala, as well as 2011 sequences from the US, which have been withheld by the CDC, would be useful.
