Difficulty: EasyDisease Surveillance and Outbreak Management

Match each infectious disease presentation to the most appropriate mandatory public health action or infection control protocol.

  • A 35-year-old patient confirmed to have active pulmonary tuberculosis.Requires airborne isolation and routine notification to the local health department.
  • A 24-year-old food handler presenting with acute hepatitis A infection.Mandates immediate exclusion from the workplace and post-exposure prophylaxis for close contacts.
  • A 6-year-old unimmunized child suspected of having paralytic poliomyelitis.Demands urgent reporting escalating to the World Health Organization (WHO) under International Health Regulations.
  • A 45-year-old hospitalized patient with uncomplicated seasonal influenza.Necessitates standard droplet precautions without individual case reporting to the health department.

Answer

Active pulmonary tuberculosis pairs with airborne isolation and local reporting. The hepatitis A infected food handler pairs with workplace exclusion and contact prophylaxis. Suspected paralytic poliomyelitis pairs with urgent international WHO reporting. Uncomplicated seasonal influenza pairs with droplet precautions and no individual reporting.
The correct pairings accurately align the infectious disease with its corresponding public health protocol based on transmission risk and severity. Tuberculosis requires airborne precautions and local tracking. Hepatitis A in a food handler risks a significant fecal-oral outbreak, necessitating work exclusion. Polio is a global eradication target requiring international notification. Seasonal influenza is managed with standard droplet precautions without individual local reporting.

Step-by-Step Solution

1
Evaluate the transmission route and public health threat of active pulmonary tuberculosis.
Recognized as an airborne pathogen requiring local health department tracking.
To ensure strict isolation protocols and initiate contact tracing for a highly contagious, reportable disease.
2
Assess the specific occupational risk of a food handler with hepatitis A.
Identified high risk for point-source outbreaks via fecal-oral transmission.
Food handlers must be immediately excluded from work, and exposed individuals need post-exposure prophylaxis to prevent an outbreak.
3
Determine the global significance of a new paralytic poliomyelitis case.
Classified as an infectious disease targeted for global eradication.
International Health Regulations mandate escalating reports of wild poliovirus to the WHO to prevent international spread.
4
Review standard reporting and isolation requirements for seasonal influenza.
Requires droplet precautions but no routine individual reporting.
Seasonal flu is endemic and widespread; individual reporting in adults would overwhelm systems, so sentinel surveillance is used instead.

Key Concept

Public health interventions are stratified based on the disease's transmission route, severity, and potential for widespread outbreaks. Mandatory reporting guidelines vary from local notification to international alerts depending on the pathogen.
