Okonkwo did not get sick. His daughter Ezinma, and his father Unoka, both got sick at different times.
Okonkwo's illness implied that he had not eaten for 2 days, that he was drinking too much and that he had not gotten proper sleep.
Okonkwo treats Ezinma's illness very seriously. He takes his aid of Ezinma very seriously as well.
Okonkwo's duty is to stay alive so that he and his family may go back to their village.

Okonkwo wanted his sons to grow up to be great warriors. So he told his sons about his wars stories, hoping to excite them and give them knowledge of wars.
He tells Okonkwo that the child is an ogbanje, a child who after dying re-enters their mother's womb to be born again.
This event did not happen. Ekwefi was still alive when Okonkwo hung himself. However, many of Ekwefi's children had died before.

Ogbuefi Ezeudu visits Okonkwo to deliver a message from the Oracle that the village has decreed for Okonkwo to be banished from the clan for seven years as punishment for committing a crime. Ezeudu delivers the message out of respect for Okonkwo's status in the community and warns him to not take any drastic actions.
"Okonkwo was a man." "Did you see that man, Okonkwo?" "You are my son. Okonkwo, I am your father!"
Firstly he calls together his sons and daughters and then Okonkwo, his nephew. He then challenges any of them to speak if they think they know more than he does; no one speaks up. Secondly, he asks Okonkwo a question to which he does not know. When Okonkwo says he does not know, Uchendu calls him a child.
Ezeudu warns Okonkwo not to participate in Ikemefuna's killing because Ikemefuna calls Okonkwo "father" and has been living with them for three years. Ezeudu fears that Okonkwo's involvement in the killing will bring him harm and cause his chi to turn against him.
