Which element is commonly included on a notifiable disease reporting form?

• A. Passport number.
• B. Vaccination status.
• C. Shoe size.
• D. Hair color.

Answer: (B)

Vaccination status is included on notifiable disease reporting forms because immunization information helps public health track how well vaccines are protecting people, identify gaps in coverage, and assess vaccine effectiveness during outbreaks. Knowing who has been vaccinated and when can clarify patterns of disease spread and guide targeted interventions, such as booster campaigns or prioritized vaccination for at-risk groups. In contrast, details like passport number, shoe size, or hair color don’t inform disease surveillance or outbreak response and raise unnecessary privacy concerns, so they aren’t part of standard reporting.
