Hello Doctor, My Husband Has Been In Bed All Day

Hello doctor, my husband has been in bed all day with chills, diarrhea, stomach cramps. He was sweating all night. WE ate Chinese take away and he had beef on Sunday, he had the leftovers yesterday, I didn't. WE both had chicken yesterday too, I'm fine. How long before I should take him to urgent care? He's been on Sprite, water and I just bought him electrolytes. He doesn't want to eat, I bought him soda crackers and offered him plain rice. He's had no food. Thank you very much. I appreciate your answer and time. Laura
