CAMRT Radiography Practice Exam

Which of the following diseases requires airborne precaution?

1. TB

2. Varicella

3. Rubella

4. TB and Varicella

The correct answer is: TB and Varicella

Airborne precautions are essential for diseases that spread through tiny respiratory droplets that remain suspended in the air for extended periods. Tuberculosis (TB) is a well-known airborne disease characterized by its long incubation period and potential for transmission through coughing or sneezing, making strict airborne precautions necessary to protect healthcare workers and other patients. Varicella, commonly known as chickenpox, also requires airborne precautions due to its highly contagious nature. The varicella virus can be transmitted through respiratory droplets as well as through direct contact with lesions, but airborne precautions are implemented to prevent the spread of the virus through the air. Thus, both TB and Varicella necessitate airborne precautions to prevent transmission in healthcare settings. It’s important to note that while rubella is contagious, it primarily spreads through respiratory droplets rather than airborne routes, typically requiring droplet precautions instead. Understanding the specific precautions required for each disease helps healthcare providers implement appropriate infection control measures, ensuring the safety of patients and staff.
