Answer
This approach is effective as it ensures diseased animals are removed from contact with healthy ones, reducing the risk of disease transmission. Vaccinating healthy animals further strengthens herd immunity.
Step 2
Vaccinate all animals so that healthy animals do not develop the disease and spread it further.

Answer
While vaccination is crucial, this method does not address the immediate risk of contact between diseased and healthy animals. It works best when combined with isolation.
Step 3
Move the diseased animals into another enclosure to quarantine them from the healthy animals.

Answer
Quarantine is an effective way to prevent further spread of the disease as it physically separates the infected from the uninfected.
Step 4
Wash all animals with antiseptic solution so that the pathogen causing the disease cannot be spread from diseased animals to healthy animals.

Answer
Although washing can reduce pathogens, it doesn't address the direct risk from diseased animals still having contact with healthy ones.
