Answer
This procedure aims to prevent the transmission of the disease by first removing the threat (diseased animals) and then protecting the healthy population through vaccination.
Step 2
Vaccinate all animals so that healthy animals do not develop the disease and spread it further.

Answer
This action is effective in containing the disease and preventing interaction with healthy animals, making it a viable option to limit spread.

Answer
Although this method may help reduce pathogens on the animal's surface, it does not directly address the disease transmission from diseased to healthy animals.
