With the program planned out to the meet you would have to skip the rest of this week and keep moving forward. With that in mind, there still might be things you can do or modifications you can make. Most lower body stuff will be out at least until the acute pain is gone, but for upper body stuff consider changing out all benching for floor pressing and trying to get your legs involved as little as possible. Static ab exercises (planks, buzzsaws, etc) should still be good, and upper back tricep work as long as you can take the legs out of it.
Once your strep is gone I’d try getting back into it with some modifications.
Once the back feels better you can start back light with lower body stuff
