For reports from the 2009-2010 season, please see http://www.dshs.state.tx.us/idcu/disease/influenza/surveillance/2010/. During week 51 in Texas: The influenza (flu) activity level (geographic spread of influenza) for Texas was "regional" and the ILINet Activity Level Indicator was "low". For more information please see http://www.cdc.gov/flu/weekly/fluactivity.htm and the national FluView weekly report at http://www.cdc.gov/flu/weekly/. One hundred and six (16.6%) specimens tested by NREVSS laboratories in Texas were positive for influenza. Two specimens were positive for influenza B by PCR testing; the remaining positive results were obtained by antigen detection test. The percentage of visits for influenza-like illness as reported by ILINet providers in Texas was below the state baseline but above the regional baseline. No influenza-associated pediatric deaths were reported. No outbreaks or school closures were reported. Reports from Health Service Regions Reports were received from all Health Service Regions (HSRs) for week 51. HSRs 4/5N, 8, 9/10, and 11 reported an increased level of flu activity compared to week 50. HSRs 1, 6/5S, and 7 reported the same level of flu activity compared to week 50. HSR 2/3 reported a decreased level of flu activity compared to week 50. For a map of Health Service Regions please visit the following website: http://www.dshs.state.tx.us/regions/state.shtm Laboratory Results Influenza During week 51, seven hospital laboratories and public health agencies across Texas reported conducting a total of 640 influenza tests (antigen, culture, and PCR) to the National Respiratory and Enteric Virus Surveillance System (NREVSS) sponsored by the Centers for Disease Control and Prevention (CDC). Eighty-six percent of the influenza tests reported to NREVSS were antigen detection tests; these tests cannot identify the subtype of influenza detected. The results from Texas participants in NREVSS are summarized in the table below. Testing Information Week 51 No. of specimens tested 640 No. of positive specimens (%) 106 (16.6%) Positive specimens by type/subtype Influenza A Subtyping performed A (2009 H1N1) A (other H1N1) A (H3N2) 91 (85.8%) 0 (0%) 0 (0%) 0 (0%) 0 (0%) Subtyping not performed 91 (100%) Influenza B 15 (14.2%) Additional influenza test results (rapid tests, culture, PCR) were reported from providers and public health departments throughout the state (see county map at the end of this report). Other Respiratory Viruses The NREVSS system collects information on a variety of respiratory viruses in addition to influenza including parainfluenza, respiratory syncytial virus (RSV), rhinovirus, human metapneumovirus (HMPV), and respiratory adenovirus. The results from week 51 are summarized below. Virus Number of Percentage Laboratories Tests Positive of Tests Testing Performed Tests Positive Adenovirus (respiratory) 3 133 5 3.76% HMPV 2 67 2 2.99% Parainfluenza 2 132 3 2.27% Rhinovirus 1 54 22 40.74% RSV 12 636 143 22.48% Antigenic Characterization Since July 2010, CDC has reported antigenic characterization results from 1 influenza A (H1N1) virus, 7 influenza A (H3N2) viruses, and 7 influenza B viruses received from the Texas Department of State Health Services (DSHS) Laboratory. Influenza A (H1N1) [1] One virus was related to A/California/07/2009-like (H1N1), the influenza A (H1N1) component of the 2010-2011 influenza vaccine for the Northern Hemisphere. Influenza A (H3N2) [7] Seven viruses were related to A/Perth/16/2009-like (H3N2), the influenza A (H3N2) component of the 2010-2011 influenza vaccine for the Northern Hemisphere. Influenza B [7] o o Victoria lineage [7] Seven influenza B viruses were related to B/Brisbane/60/2008-like, the influenza B component of the 2010-2011 influenza vaccine for the Northern Hemisphere. Yamagata lineage [0] No influenza B viruses of the Yamagata lineage have been characterized since 2009. The national antigenic characterization and antiviral resistance testing results may be found in the final CDC weekly flu report at www.cdc.gov/flu/weekly/. The DSHS Laboratory sends a representative sample of influenza viruses to the CDC throughout the flu season. Antiviral Resistance Since July 2010, CDC has not reported any antiviral resistance testing results on influenza isolates received from Texas laboratories. Influenza–Associated Pediatric Mortality No influenza-associated pediatric deaths were reported during week 51. One influenzaassociated pediatric fatality has been reported in Texas since the beginning of the 2010-2011 influenza season. Seven deaths have been reported during calendar year 2010. Please see the table below for more information.

Please see http://www.dshs.state.tx.us/idcu/investigation/conditions/ for more information. Influenza-Associated Deaths in Pregnant and Postpartum Women No new influenza-associated deaths were reported in pregnant or postpartum women during week 51. DSHS is requesting reporting of influenza-associated deaths in pregnant or postpartum (up to 6 weeks) women during the summer of 2010 and continuing throughout the 2010-2011 influenza season. There has been 1 death reported since the beginning of the summer 2010. All influenza types and subtypes should be reported; a positive rapid influenza test is sufficient for confirmation. School Closures and Institutional Outbreaks No school closures or institutional outbreaks were reported during week 51. Information on the control of influenza in various settings may be found on the CDC website at http://www.cdc.gov/flu/professionals/infectioncontrol/. U.S. Outpatient Influenza-like Illness Surveillance Network Fifty-seven providers in Texas reported data to the U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet) (formerly known as the U.S. Influenza Sentinel Provider Surveillance System) on patients with influenza-like illness (ILI) and total patients seen for any reason during week 51. Of the 52 providers who saw patients, 38 (73%) saw at least one patient with ILI. Of all patient visits during this week, 5.34% were due to ILI. The Texas ILI baseline is 6.09% for the 2010-2011 season. The ILI baseline for HHS Region 6 (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas) of the United States is 4.9% for the 2010-2011 season. The baseline is the mean percentage of patient visits for ILI during non-influenza weeks for the previous three seasons plus two standard deviations. The baselines displayed on the graph below were calculated for the official influenza reporting season only (approximately October to May).

International Influenza Activity The CDC compiles information from several sources and releases an international influenza summary. This report can be found at http://www.cdc.gov/flu/international/activity.htm. 1 Influenza activity level corresponds to current MMWR week only and does not reflect previous weeks' activity. 2 The majority of influenza cases are not reportable by law to the Texas Department of State Health Services. This map contains data from sentinel sites and does not represent all influenza cases in the state. 3 Positive laboratory results are reported according to specimen collection date or date received in the lab if the former is unknown. 2010 - 2011 Texas Influenza Surveillance Information --- Flu Reports For the week ending: 10/09/10; 10/16/10; 10/23/10; 10/30/10; 11/06/10; 11/13/10; 11/20/10; 11/27/10; 12/04/10; 12/11/10; 12/18/10; 12/25/10; 01/01/11; 01/08/11; 01/15/11; 01/22/11; 01/29/11; Return to the Top of the Page Last updated March 21, 2011 Antiviral Guidance Conferences Other Sites Influenza FAQs Vaccine Reporting Surveillance Immunization Branch Suggested Items o Cold-Flu Prevention o Avian Flu o Vaccine Preventable Diseases Contact Us | Visitor Information | Site Map | Search | Topics A-Z | Compact with Texans | File Viewing Information Internet Policy | HHS Agencies | Homeland Security | Statewide Search | Texas.gov | Privacy Practices | Report Fraud
