Antigenic Characterization: CDC has antigenically characterized413 influenza viruses [17 2009H1N1 viruses, 281 influenza A (H3N2) viruses, and 115 influenza B viruses] collected by U.S.laboratories since October 1, 2012.

2009 H1N1 [17] All 17 2009 H1N1 viruses tested were characterized as A/California/7/2009-like, the

influenza A (H1N1) component of the 2012-2013 influenza vaccine for the NorthernHemisphere.

Influenza A (H3N2) [281]:

279 (99.3%) of the 281 H3N2 influenza viruses tested have been characterized asA/Victoria/361/2011-like, the influenza A (H3N2) component of the 2012-2013 NorthernHemisphere influenza vaccine.

2 (0.7%) of the 281 H3N2 viruses tested showed reduced titers with antiserum producedagainst A/Victoria/361/2011.

Influenza B (B/Yamagata/16/88 and B/Victoria/02/87 lineages) [115]:

Yamagata Lineage [79]: 79 (68.7%) of the 115 influenza B viruses tested so far this seasonhave been characterized as B/Wisconsin/1/2010-like, the influenza B component of the2012-2013 Northern Hemisphere influenza vaccine.

Victoria Lineage [36]: 36 (31.3%) of 115 influenza B viruses tested have been from theB/Victoria lineage of viruses.


4/28


Antiviral Resistance: Testing of 2009 H1N1, influenza A (H3N2), and influenza B virus isolates forresistance to neuraminidase inhibitors (oseltamivir and zanamivir) is performed at CDC using afunctional assay. Additional 2009 influenza A (H1N1) clinical samples are tested for a singlemutation in the neuraminidase of the virus known to confer oseltamivir resistance (H275Y). Thedata summarized below combine the results of both testing methods. These samples are routinelyobtained for surveillance purposes rather than for diagnostic testing of patients suspected to be

infected with antiviral-resistant virus.

High levels of resistance to the adamantanes (amantadine and rimantadine) persist among 2009influenza A (H1N1) and A (H3N2) viruses (the adamantanes are not effective against influenza Bviruses). As a result, data from adamantane resistance testing are not presented below.

The majority of currently circulating influenza viruses are susceptible to the neuraminidase inhibitorantiviral medications oseltamivir and zanamivir; however, rare sporadic cases of oseltamivir-resistant 2009 H1N1 and A (H3N2) viruses have been detected worldwide. Antiviral treatment withoseltamivir or zanamivir is recommended as early as possible for patients with confirmed or

suspected influenza who have severe, complicated, or progressive illness; who requirehospitalization; or who are at greater risk for serious influenza-related complications. Additionalinformation on recommendations for treatment and chemoprophylaxis of influenza virus infectionwith antiviral agents is available at http://www.cdc.gov/flu/antivirals/index.htm .

Novel Influenza A Virus: No new human infections with novel influenza A viruses were reported toCDC during week 52.

A total of 312 infections with variant influenza viruses (308 H3N2v viruses, 3 H1N2v viruses, and 1H1N1v virus) have beenreportedfrom 11 states since July 2012. More information about H3N2vinfectionscan be found at http://www.cdc.gov/flu/swineflu/h3n2v-cases.htm .

Influenza-Associated Hospitalizations: The Influenza Hospitalization Surveillance Network(FluSurv-NET) conducts population-based surveillance for laboratory-confirmed influenza-relatedhospitalizations in children younger than 18 years of age (since the 2003-2004 influenza season)and adults (since the 2005-2006 influenza season).

The FluSurv-NET covers more than 80 counties in the 10 Emerging Infections Program (EIP) states(CA, CO, CT, GA, MD, MN, NM, NY, OR, TN) and additional Influenza Hospitalization SurveillanceProject (IHSP) states. The IHSP began during the 2009-2010 season to enhance surveillanceduring the 2009 H1N1 pandemic. IHSP sites included IA, ID, MI, OK and SD during the 2009-2010season; ID, MI, OH, OK, RI, and UT during the 2010-2011 season; MI, OH, RI, and UT during the2011-2012 season; and IA, MI, OH, RI, and UT during the 2012-2013 season.

Data gathered are used to estimate age-specific hospitalization rates on a weekly basis, anddescribe characteristics of persons hospitalized with severe influenza illness. The rates provided


7/28


are likely to be an underestimate as influenza-related hospitalizations can be missed, eitherbecause testing is not performed, or because cases may be attributed to other causes ofpneumonia or other common influenza-related complications.

Between October 1, 2012 and December 29, 2012, 2,257 laboratory-confirmed influenza-associated hospitalizations were reported. This is a rate of 8.1 per 100,000 population. Among all

hospitalizations, 1,924 (85.2%) were associated with influenza A and 312 (13.8%) with influenza B.There was no virus type information for 19 (0.8%) hospitalizations. Among hospitalizations withinfluenza A subtype information, 475 (98.1%) were attributed to H3 and 9 (1.9%) were attributed to2009 H1N1. The most commonly reported underlying medical conditions among hospitalized adultswere metabolic conditions, cardiovascular disease, obesity, and chronic lung disease (excludingasthma). Among 36 hospitalized women of childbearing age (15-44 years), seven were pregnant.The most commonly reported underlying medical conditions in hospitalized children were asthma,neurologic disorders, and immune suppression. Approximately 40% of hospitalized children had noidentified underlying medical conditions. Additional FluSurv-NET data can be found at:http://gis.cdc.gov/GRASP/Fluview/FluHospRates.html .

Data from the Influenza Hospitalization Surveillance Network (FluSurv-NET), a population-based surveillance for influenza

related hospitalizations in children and adults in 15 US states. Incidence rates are calculated using the National Center for

Health Statistics (NCHS) population estimates for the counties included in the surveillance catchment area.

Asthma includes a medical diagnosis of asthma or reactive airway disease; Cardiovascular diseases include conditionssuch as coronary heart disease, cardiac valve disorders, congestive heart failure, and pulmonary hypertension (does notinclude isolated hypertension); Chronic lung diseases include conditions such as bronchiolitis obliterans, chronicaspiration pneumonia, and interstitial lung disease; Immune suppression includes conditions such as immunoglobulindeficiency, leukemia, lymphoma, HIV/AIDS, and individuals taking immunosuppressive medications; Metabolic disordersinclude conditions such as diabetes mellitus, thyroid dysfunction, adrenal insufficiency, and liver disease; Neurologicdiseases include conditions such as seizure disorders, cerebral palsy, and cognitive dysfunction; Neuromusculardiseases include conditions such as multiple sclerosis and muscular dystrophy; Obesity was assigned if indicated inpatients medical chart or if body mass index (BMI) >30 kg/m

2; Pregnancy percentage calculated using number of female

cases aged between 15 and 44 years of age as the denominator; Renal diseases include conditions such as acute orchronic renal failure, nephrotic syndrome, glomerulonephritis, and impaired creatinine clearance; No known conditionindicates that the case did not have any known underlying medical condition indicated in medical chart at the time ofhospitalization.Only includes cases for which data collection has been completed through the medical chart review stage.

Outpatient Illness Surveillance: Nationwide during week 52, 5.6% of patient visits reportedthrough the U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet) were due toinfluenza-like illness (ILI). This percentage is above the national baseline of 2.2%. This increasemay be attributed in part to a reduced number of routine health care visits during the Christmasholidays, which has been observed in previous seasons.

(ILI is defined as fever (temperature of 100F [37.8C] or greater) and cough and/or sore throat.)

ILINet Activity Indicator Map:Data collected in ILINet are used to produce a measure of ILIactivity* by state. Activity levels are based on the percent of outpatient visits in a state due to ILIand are compared to the average percent of ILI visits that occur during spring and fall weeks withlittle or no influenza virus circulation. Activity levels range from minimal, which would correspond toILI activity from outpatient clinics being below the average, to high, which would correspond to ILIactivity from outpatient clinics being much higher than average.

During week 52, the following ILI activity levels were experienced: New York City and 29 states experienced high ILI activity (Alabama, Arkansas, Colorado,

Florida, Georgia, Illinois, Indiana, Kansas, Louisiana, Massachusetts, Michigan, Minnesota,Mississippi, Missouri, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma,Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia,and Wyoming).

Nine states experienced moderate ILI activity (Alaska, Arizona, Delaware, Iowa, Nebraska,North Dakota, Oregon, Washington, and West Virginia).

Four states experienced low ILI activity (Kentucky, New Hampshire, South Dakota, andWisconsin).

Six states experienced minimal ILI activity (California, Connecticut, Hawaii, Maine, Montana,

and Nevada). Data were insufficient to calculate an ILI activity level for the District of Columbia and 2

states (Idaho and Maryland).

*This map uses the proportion of outpatient visits to health care providers for influenza-like illness to measure the ILI activity level within astate. It does not, however, measure the extent of geographic spread of flu within a state. Therefore, outbreaks occurring in a single citycould cause the state to display high activity levels.Data collected in ILINet may disproportionally represent certain populations within a state, and therefore, may not accurately depict thefull picture of influenza activity for the whole state.Data displayed in this map are based on data collected in ILINet, whereas the State and Territorial flu activity map is based on reportsfrom state and territorial epidemiologists. The data presented in this map is preliminary and may change as more data is received.Differences in the data presented here by CDC and independently by some state health departments likely represent differing levels ofdata completeness with data presented by the state likely being the more complete.

Geographic Spread of Influenza as Assessed by State and Territorial Epidemiologists: Theinfluenza activity reported by state and territorial epidemiologists indicates geographic spread ofinfluenza viruses, but does not measure the severity of influenza activity.

During week 52, the following influenza activity was reported: Widespread influenza activity was reported by 41 states (Alabama, Alaska, Arkansas,

Colorado, Connecticut, Florida, Georgia, Kentucky, Idaho, Illinois, Indiana, Iowa, Kansas,Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Nebraska,Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, NorthDakota, Ohio, Oklahoma, Pennsylvania, South Carolina, Rhode Island, Tennessee, Texas,Utah, Vermont, Virginia, West Virginia, Wisconsin, and Wyoming).

Regional influenza activity was reported by 7 states (Arizona, California, Missouri, Montana,Oregon, South Dakota, and Washington).

The District of Columbia reported local influenza activity. Sporadic influenza activity was reported by 1 state (Hawaii). Guam reported no influenza activity.

Puerto Rico, the U.S. Virgin Islands, and 1 state (Delaware) did not report.
