1 Surveillance Update TISWG May, 2011 Rachel Wiseman, MPH Epidemiologist Emerging and Acute Infectious Diseases May 18, 2011

2 VPDs in Texas, 2005-2010 200520062007200820092010 Hep A461330264259184139 Hep B742833741562420394 Peri Hep B813812 HIB8111411712 Measles307010 Meningo- coccal 614555705359 Mumps2558212040121 Pertussis2,2249541,0512,0463,3582,848 Pneumo- coccal 7359011,4171,8841,9521,912 Tetanus010310 Varicella8,33611,76810,0617,8394,4452,760

3 2010 Deaths Pertussis: NONE!! Meningococcal: 3 (lower than expected) Pneumococcal: 123 (expected) Varicella: 2 All other VPDs: NONE!! Unfortunately we did recently have a 2011 pertussis death  Too young for vaccination  No contacts with pertussis

4 Correctional Mumps Outbreaks, 2010-11 July-September 2010  Primarily Central, NE Texas  30 cases October 2010  Valley  9 cases December 2010-March 2011  Most of the state except N Texas, W Texas  35 cases

5 Measles 2011 89 cases reported to CDC in 2011  Annual average ~50 Outbreaks in Europe Endemic areas Outbreaks in multiple US states Texas has 6 cases in 2011  Most characterized by delays in diagnosis and/or reporting

6 2011 Measles Cases—Texas Case 1. Unvaccinated 23 mo from Houston area  Travel to Philippines  Parents “too busy” to vaccinate Case 2. Unvaccinated 7 mo from Houston area  Travel to India, probably exposed on flight home Children as young as SIX months can receive MMR if they are going to be traveling abroad

7 2011 Measles Cases—Texas (2) Exposed at Trade Show in Orlando Florida Case 3. Adult with 1 MMR Case 4. Unvaccinated spouse of above Case 5. Unvaccinated adult Case 6. Unvaccinated 11 month old child No secondary transmission except from 4 to 5. Two cases identified in other states, not Florida.

8 Peak: week 7

9 Texas Flu Summary, 2010-2011 Predominant influenza type: A  Subtype: H3N2 Seasonal peaks  ILINet peak: mid February  Laboratory peaks:  mid to late January  mid February

10 CDC Grant Objectives (1) 90% of VPD investigations are sent to CDC within 30 days of receiving report  Texas reality: <80% within 30 days Why timeliness is important  Many interventions have time restrictions  Detect state-wide or national trends/outbreaks Improvement Plan  Provide semi-annual feedback to locals/regions on timeliness  Improve turn around time at Central Office

11 CDC Grant Objectives (2) Known vaccination status for at least 90% of cases Texas reality  100% HIB <5 years  36% meningococcal  75% in <18 age group  70% mumps  93% in <18 age group  79% pertussis  92% in <18 age group

12 CDC Grant Objectives (2) Capturing vaccination status is important to assess control measures, vaccine efficacy/schedule, vaccination policies, etc Giving feedback to local and regional health departments on semi-annual basis  Include reminders about all possible ways to capture vaccine information Exploring ways to streamline data capture (can Immtrac talk to our database?)

13 Questions?
