Which of the following is NOT one of the five pathogens tracked by NWSS?

• A. Measles
• B. Influenza
• C. RSV
• D. Hepatitis B

Answer: (D)

NWSS focuses on a small set of pathogens that are most useful for rapid outbreak detection and timely public health action. Measles, influenza, and RSV are all acute, often outbreak-prone respiratory infections that are closely watched for seasonal patterns, vaccine effectiveness, and immediate control measures. Hepatitis B, by contrast, is typically a chronic infection with slower, long-term transmission dynamics and is monitored through different surveillance channels rather than the NWSS rapid-outbreak signal set. That’s why Hepatitis B isn’t included among the five pathogens tracked by NWSS.
