What is the second step in the cleaning protocol for suspected rodent-contaminated areas?

• A. Wet contaminated areas with detergent or liquid to deactivate the virus
• B. Put on latex gloves
• C. Spray dead rodents with disinfectant
• D. Open the building to air out

Answer: (A)

The main idea being tested is how to sequence steps to reduce the risk from rodent-contaminated areas by preventing the virus from becoming airborne during cleanup. Wetting contaminated areas with detergent or a cleaning liquid is the best second step because it directly lowers the chance of aerosolizing any virus particles that may be present in droppings, urine, or dust. The liquid deactivates or loosens materials, making it safer to remove and disinfect later, and it helps keep dirt and contaminants from becoming airborne as you proceed with cleanup. Wearing gloves and other protective gear should come first to protect you during cleaning, and ventilation or opening the area to air out is handled as part of preparation, but wetting the surfaces is the key next move to minimize exposure before you continue with removal and disinfection.
