How to get my dog to eat? ?

Heyy guys!! Okay so my dog is about 4 years old and he got super super sick a couple weeks ago. ( my vet said he had a bad worm inside him that could catch onto people. But luckily no one in my family got it) but anyways he won't eat or drink anything. We also tried about 10 different types of dog food and canned dog food. And he's not eating it. And he drinks toilet water?!? And i know that's kinda bad for dogs, also it's nasty. So, what I'm asking is do any of you guys know how to get him to eat any type of food?? Or human food, because he wont even eat that. So yeah and also can you tell me how we can et him to drink ou of his bowl. Cuz uhm yea. But thanks and if u can anwser my question about how I can get him to eat any type of food and get him to drink? Thanks! :)
