Epidemiology and Surveillance

Epidemiology and Surveillance

Detecting outbreaks, implementing control measures,  program planning, and evaluation require collection, analysis, interpretation and reporting of disease morbidity and mortality data and vaccination coverage data.

Program activities must be conducted to ensure compliance with the Communicable Disease Prevention and Control Act (Health and Safety Code, Chapter 81), the Texas Administrative Code (Title 25, Part 1, Chapter 97), the Emerging and Acute Infectious Disease Guidelines (Stock No. 6-106), and the NBS Data Entry Guidelines.

If you have questions or need to submit a data request, please contact Imm.Epi@dshs.texas.gov for vaccination data. For vaccine preventable disease data or surveillance questions, please contact feedback.IDCU@dshs.texas.gov

Perinatal Hepatitis B Prevention Program

Perinatal Hepatitis B prevention happens through an organized and coordinated approach, Combining case management, provider education, and policy recommendation.

The DSHS PHR PHBPP Coordinators and LHD case managers should conduct case management on HBsAg-positive mothers, their infant(s), and household contacts ≤ 24 months of age according to the PHBPP guidelines. 

Case management in the PHBPP involves:

  1. Identifying and interviewing HBsAg-positive mothers and performing tasks such as providing information (brochures).
  2. Educating HBsAg–positive women, their families, and their healthcare providers.
  3. Ensuring children born to HBsAg-positive mothers receive appropriate prophylaxis at birth and receive the hepatitis B vaccine series on time and are appropriately evaluated for immunity or infection after receiving the series.
  4. Making recommendations for referral.
  5. Collecting contact information (sexual and household) for appropriate referrals.
