So everyone gets sick at one point in their lives. And if you tell me that you've never gotten sick...

Just wait.

Anyways, so this is how things would be when the girls get sick.

Ace: doing everything he can to make her feel better. He's keeping her warm if she's cold, he's going to the doctors and asking what medicines to give her. He is hand feeding her soup, he's keeping her in bed. Meanwhile she's going "Ace, it's just a cold."

Luffy: having no knowledge of how to help someone who's sick, he'll take her directly to Chopper. He'll hover over Chopper and try to learn what to do to take care of her. After Chopper repeatedly tells Luffy he'll handle it, Luffy will just cuddle her.

Sabo: sitting by her bedside while doctors look over her. After doctors give her medicine and tell him to let her rest, he does everything to make sure she's comfortable. He'll play with her hair and speak softly to her to avoid giving her a headache.

Marco: he's pretty chill about it despite being worried. He'll get a doctor to check her over and when he knows what's wrong, he'll make sure she's comfortable and even gently massage where it hurts in her until she's asleep. Then he'll lie beside her in case she needs anything when she wakes up.

Law: he's a doctor. He knows what he's doing. But that's not going to stop him from worrying about her. If she's sick for longer than 2 days, he'll start to wonder if he's doing something wrong and get really frustrated. Then she'll ask him to cuddle with her. When she falls asleep in his arms, he'll remind himself that she's not dying. Just sick and not to freak out.

Zoro: lets Chopper do his thing. While Chopper checks her for the cause of illness, he'll -very embarassedly- ask Sanji to make her favorite soup. After she's released to rest and the soup is done, He helps her eat and then will cuddle her until she feels better, playing with her hair the entire time to relax her.

Now when the boys are sick.

Aoi: similar to Law. She's a doctor, she knows what she's doing, even if she has to fight with Ace to take his medicine. After finally forcing him to take the medicine, she'll sing soft love songs and lullabies to him to help him sleep. She'll also gently rub his tummy to relax him.

Aisuru: will be exteremly worried. She'll keep calm infront if Luffy and sing to him to help him sleep. But she will also sit outside of the door and cry worriedly. She did watch her mother die of disease and she'll be terrified of Luffy getting the same illness and dying. When he's finally better she'll spend a whole day just hugging him in relief.

Ginger: will sit by his bedside and refuse to leave for anything. Only if Sabo tells her to leave his side to take care of herself will she move. Then she'll take care of her needs quickly and be right back at his side, making sure he's comfortable, getting him anything he needs and, of course, cuddling him in to submission.

Yatsumi: surprisingly calm about the whole thing. She'll still take care of her duties, but will also check on Marco every few hours to make sure he's okay and get him anything he needs. When he asks her to stay, she'll sit on the bed beside him and rub his back until he falls asleep.

Aka: much like Ginger, Aka will refuse to leave Law's side. Though Law can't get her to leave simply by telling her to. Any time he tells her to go take care of herself, she will scold him and tell him that as a doctor he should take better care of himself and until his health is back, she will take care of him.

Ki: does every little thing Zoro asks her to. From adjusting his pillows to massaging his sore muscles, Ki won't do anything unless Zoro asks her to do it for him. When he's sick, he's her first priority. Everything else can wait.
