When someone is "sent to the isolation," it generally means they are being separated from others due to illness or a contagious condition. However, there are various synonyms that can be used for "sent to the isolation." For instance, someone might be "quarantined," "isolated," "segregated," or "sequestered." These terms are relevant depending on the context and the reason for separating the individual. For example, "quarantine" and "isolation" are often used in medical contexts, while "segregated" and "sequestered" typically refer to social or legal actions. Using the right synonym can help to add precision and clarity to a discussion about isolating individuals for reasons of health or safety.
