state of being cut off from others
a state where a person, group, or place is away from other people and has very little contact with them
用法パターン：
in isolation from [someone/something]
よくある間違い：
Learners sometimes use "isolation" when they only mean a positive, peaceful time alone. In that case, "solitude" or "privacy" may be better. They also sometimes confuse "isolation" with "insulation" (used for keeping heat or sound in or out).
類義語
loneliness (focuses more on the sad feeling of being alone, while isolation can be more neutral or physical.)

対義語
context (refers to all the other related facts and situations, which is what is missing when something is seen in isolation.)

medical separation to stop infection
a state where a sick person, or someone who may be sick, stays away from other people so they do not spread disease
用法パターン：
be in isolation for [length of time]
よくある間違い：
Learners sometimes use "quarantine" and "isolation" as if they are always the same. In medical English, "isolation" usually means keeping people who are known or strongly suspected to be infectious away from others, while "quarantine" is often for people who may have been exposed but are not known to be sick yet.
類義語
quarantine (very close in meaning, but "quarantine" is often used more generally for keeping people or animals away after possible exposure, while "isolation" usually refers to confirmed or likely cases.)
対義語
