The stage of illness during which a person regains normal health status

Convalescent period.

Explanation:

The word convalescence originates from the Latin convalescentia, which means to regain strength. The recovery time that a person spends after a disease is called convalescence. It is during this period that the body needs to gradually recover from some disease, because your body is returning to normal health. The person who is in the convalescent state is called the convalescent.

Just as each patient has a unique response to the disease, the convalescence period varies with each specific pathology. Other factors such as age and general health of the patient are also taken into account. Because of all these criteria, the idea of convalescence time is very flexible and broad, ranging from just a few days to several months.
