Key Flu Indicators
According to this week's FluView report, flu activity is increasing in parts of the country and following an upward trend nationally. Anyone 6 months and older who has not gotten a flu vaccine yet this season should get one now. Below is a summary of the key indicators for the week of December 1-7, 2013:
•For the week of December 1-7, the proportion of people seeing their health care provider for influenza-like illness (ILI) increased, and is now slightly above the national baseline. Three regions reported ILI activity above their region-specific baseline level. The other seven regions reported activity levels below region-specific baselines.
•Four states (Alabama, Louisiana, Mississippi and Texas) experienced high ILI activity this week; an increase from two states in the previous week. Five states (Arkansas, Colorado, Oklahoma, South Carolina, and Utah) experienced low ILI activity. Forty-one states experienced minimal ILI activity. The District of Columbia did not have sufficient data to calculate an activity level. ILI activity data indicate the amount of flu-like illness that is occurring in each state.
•Fourteen states reported regional geographic influenza activity; an increase from six jurisdictions in the previous week. Thirteen states reported local activity. This is an increase from ten states last week. The District of Columbia, Guam, Puerto Rico, and 27 states reported sporadic influenza activity. The U.S. Virgin Islands and one state (Vermont) reported no influenza activity. Geographic spread data show how many areas within a state or territory are seeing flu activity.
•Since October 1, 2013, 531 laboratory-confirmed influenza-associated hospitalizations have been reported. This translates to a cumulative rate of 2.0 hospitalizations per 100,000 people in the United States.
◦Hospitalization data are collected from 13 states and represent approximately 9% of the total U.S. population. The number of hospitalizations reported does not reflect the actual total number of influenza-associated hospitalizations in the United States.
•The proportion of deaths attributed to pneumonia and influenza (P&I) based on the 122 Cities Mortality Reporting System increased, but remains below the epidemic threshold.
•No influenza-associated pediatric deaths were reported to CDC during the week of December 1-7. A total of three influenza-associated pediatric deaths have been reported for the 2013-2014 season.
•Nationally, the percentage of respiratory specimens testing positive for influenza viruses in the United States during the week of December 1-7 increased for the seventh consecutive week from 11.1% to 13.3%. During the last three weeks, the regional percentage of respiratory specimens testing positive for influenza viruses ranged from 3.3% to 16.8%.
•Influenza A (H3N2), 2009 influenza A (H1N1), and influenza B viruses have all been identified in the U.S. this season. During the week of December 1-7, 780 of the 830 influenza-positive tests reported to CDC were influenza A viruses and 50 were influenza B viruses. Of the 395 influenza A viruses that were subtyped 3.5% were H3 viruses and 96.5% were 2009 H1N1 viruses.
•CDC has antigenically characterized 221 influenza viruses, including 184 2009 influenza A (H1N1) viruses, 31 influenza A (H3N2) viruses, and 6 influenza B virus, collected since October 1, 2013.
◦All 184 of the 2009 influenza A (H1N1) viruses tested were characterized as A/California/7/2009-like. This is the influenza A (H1N1) component of the Northern Hemisphere quadrivalent and trivalent vaccines for the 2013-2014 season.
◦All 31 of the influenza A (H3N2) viruses tested were characterized as Texas/50/2012-like. This is the influenza A (H3N2) component of the Northern Hemisphere quadrivalent and trivalent vaccines for the 2013-2014 season.
◦Two of the six influenza B viruses tested belonged to the B/Yamagata lineage of viruses, and were characterized as B/Massachusetts/02/2012-like. This is an influenza B component for the 2013-2014 Northern Hemisphere quadrivalent and trivalent influenza vaccines.
◦The four other influenza B viruses belonged to the B/Brisbane lineage of viruses, were characterized as B/Brisbane/60/2008-like. This is an influenza B component of the 2013-2014 Northern Hemisphere quadrivalent influenza vaccine.
•Since October 1, 2013, CDC has tested 395 2009 influenza A (H1N1), 55 influenza A (H3N2), and 13 influenza B virus samples for resistance to neuraminidase inhibitors. While the majority of the tested viruses showed susceptibility to the antiviral drugs oseltamivir and zanamivir, one additional 2009 H1N1 virus proved resistant to oseltamivir during the week of December 1-7, though the virus was sensitive to zanamivir. In total, seven 2009 H1N1 viruses have shown resistance to oseltamivir so far this season, though each of the viruses has been sensitive to zanamivir.
◦High levels of resistance to the adamantanes (amantadine and rimantadine) persist among 2009 influenza A (H1N1) and A (H3N2) viruses. Adamantanes are not effective against influenza B viruses.
