Is it implied by Aisha's hadith that she would leave the I'tikaf to go home for a need, and if so, who is the sick person mentioned in the hadith?

This hadith was narrated by Muslim, Ibn Majah, and Ahmad, and it states that Aisha used to enter the house when a sick person was in it to inquire about him as she passed by. It also states that the Prophet, peace and blessings be upon him, would put his head into her room from the mosque for her to comb his hair while he was in i'tikaf, and he would not enter the house except for a need. The phrase "for a need" refers to fulfilling a human need [such as using the restroom]. This means she would inquire about the sick person without stopping, because it is the Sunnah for one observing i'tikaf not to leave the mosque to visit the sick. The name of the sick person was not mentioned in any narration.
