What are sequelae in a medical context?

Sequelae in a medical context refer to secondary conditions or long-term complications that result from an initial infection or disease. They are often the lasting effects that continue after the primary condition has resolved. For instance, someone who has recovered from a severe case of chickenpox may experience lingering symptoms such as scarring or shingles later in life; these are considered sequelae of the original infection. Understanding sequelae is crucial in public health to anticipate and manage these ongoing health issues, ensuring proper follow-up care and resource allocation for affected patients. The other choices do not accurately capture the concept of sequelae, as they describe other aspects of health conditions rather than the long-term consequences resulting from earlier illnesses.
