وفاة 1300 على الأقل في أمريكا بسبب الأنفلونزا
Influenza Sickens Millions Across US, at Least 1300 Deaths: CDC
https://www.medscape.com/viewarticle/92 ... _flu&faf=1
Influenza activity increased again during the week ending December 7 (week 49), according to a report from the Centers for Disease Control and Prevention (CDC).
Influenza activity has now been at or above the national baseline for 5 weeks and almost half of the country is experiencing widespread illness. Influenza activity is at or above the baseline in all 10 regions of the United States.
CDC estimates that at least 2.6 million illnesses, 23,000 hospitalizations, and at least 1300 deaths have resulted from influenza so far this season.
One indicator — the proportion of outpatient visits for influenza-like illness (ILI) — fell slightly to 3.2% from 3.5% the week before, a decrease that was likely a result of the Thanksgiving holiday, the CDC explains.
Similar dips have occurred at this point during previous influenza seasons as well. Last season at this time, the proportion of outpatient visits was 2.2% and did not reach current levels until week 51, when it was 3.3%.
Nationally, the predominant strain is B/Victoria, followed by A(H1N1)pdm09 and A(H3N2). It is unusual to have B/Victoria as the predominant strain this early in the season, according to the CDC. Influenza A(H1N1) viruses are also increasing. Last season at this time, influenza A viruses predominated.
Influenza activity was high in Puerto Rico and 11 states (AL, AR, GA, MS, NE, NM, SC, TN, TX, VA, and WA) and moderate in New York City and 11 states (AZ, CO, CT, HI, KY, MD, MN, NV, NJ, OK, and OR). The rest of the country had low or minimal activity.
Influenza activity was "widespread" in 23 states (AL, AZ, CA, CT, GA, ID, IN, KY, LA, MD, MA, NE, NV, NM, NY, NC, OR, PA, SC, TN, TX, VA, WA) and "regional" in Puerto Rico and 14 states (AK, CO, FL, IL, MI, MN, MS, MT, NJ, OH, OK, RI, UT, and WI). Activity was local or sporadic in the remaining jurisdictions.
