Hubby has a fever/flu

I got a flu shot but am nervous about catching his flu. I called my doc to see if he'd put husband on antibiotics, but he said for him to drink Sprite with salt instead. Then I reminded him I'm pregnant and it could be dangerous if I get it. He said, "if you get it, drink the same thing." What the f*** kind of advice is that?
Anyone have experience with this? If I get the flu with a fever, should I just go to the hospital? 
At this point I trust all of you more than my doc 👍🏽😊  
Thanks!
