Come atteso, dagli Stati Uniti d'America arrivano i primi cenni di ripresa dell'attività influenzale .
Se si tratti oppure no della attesa e temuta " terza ondata " (per gli USA) è soon enough, but some indicators released yesterday by the CDC in Atlanta might lead us to think.
The chart published in this article indicates the number of hits ILI (influenza-like illness) in the USA and, although the most recent available, they updated the week 51 (from 20 to 26 December 2009 ).
At international level CDC confirmed that the serum samples by sentinel physicians continue to indicate a predominance of the pandemic strain A (H1N1) 2009 virtually throughout the Northern Hemisphere, except for a small percentage of the seasonal virus in Southeast Asia.
Apparently, at least for the week 51, the Influence season still does not spread to latitudes , leaving the field open to the pandemic virus.
will be interesting to follow the report that will be broadcast tomorrow ECDC European to make a comparison with the data now received from the U.S. CDC and see how the situation has evolved in the "old continent".
