Quarantine is most effective during the susceptibility stage of a communicable disease. At this point, individuals have not yet been exposed to the disease, which means they are still at risk of infection. Implementing quarantine measures here helps prevent potential exposure to pathogens among susceptible populations. By isolating individuals who may be at risk or who have been exposed to a communicable disease, public health officials can significantly reduce the chances of the disease spreading.

In contrast, during later stages such as the subclinical disease or clinical disease stage, individuals may already be infected and potentially contagious. Quarantine at this stage is less effective in halting the spread, as those with the disease can interact with others before they are identified and isolated. The resolution stage indicates recovery from the disease, at which point quarantine is unnecessary and not beneficial since the risk of spreading the disease has diminished significantly. This rationale clarifies why the susceptibility stage is critical for implementing effective quarantine measures.
