So two days ago I had diarrhea twice in the morning and then nausea and a slight fever throughout the day. I was over it by the next day. So then two day later (today) my dad woke up with diarhea and nausea. So I had thought that my weird sickness was due to a chicken sandwich that I ate the night before but now since my dad has a similar thing, I'm thinking that it could have been contagious? But he was barely around me so I'm a little confused. The only reason I am worried is because my dad mom and I all had El Pollo Loco last night so I'm worried that he has food poisoning and that I'll get it too but it just hasnt hit me yet?? This whole situation is pretty weird. I feel like I would have felt way worse when I was sick if it was a contagious sv. Any advice?
