Percy has two types of illness: ultimate hero who can fight through any cold or a sniffling child who refuses to leave the living room couch.

Annabeth's office appreciates when Percy leaves them a message about her needing to stay home from work, especially when they can hear her scratchy cries of protest in the back ground of the message.

Sally got an emergency call from the couple one winter, and arrived at their apartment to find the couple curled up on the couch with bright red noses and so many blankets she could only see their faces.

Percy likes to blame Annabeth for getting him sick.

Percy's pick for sick-day-soup is star chicken and noodle soup

Annabeth's pick for sick-day-soup is basil tomato

Every time Annabeth gets sick, Percy picks out her favorite pair of fuzzy socks and six books he knows she'll finish in two days despite how long they are
