From Recombinomics, an update on the ongoing health disaster in the Ukraine...

The above tally is from the latest update from the Ukraine Ministry of Health.  The 344 dead represents an increase of 16 from yesterday's total, which is similar to recent daily increases (see map).  The steady climb in fatal cases highlights the importance of the release of sequences by Mill Hill a WHO regional center in London.

Included in the sequences from 10 isolates were four HA sequences with the receptor binding domain change, D225G, which was found in the one throat and three lung samples.  The change was not found in isolates from nasopharyngeal washes, suggesting D225G may lead to high concentrations of H1N1 in patient's lungs.  The high concentration of virus leads to a cytokine storm that destroys the lungs in a few days.

...this is very similar to what happened in 1918 with the "Spanish" flu that killed millions.
