Bad beginning, but your writing is ok. This whole passage seems like a beginning, even though everyone dies. You need to have more of an attachment to the character, then if you wish let them...die, sadly. It's much more of an impact on the reader and they want to read more. When you wrote that Matthew had the plague less severely, you wrote he was going to die. Why even say it wasn't as severe if it still meant death? One more thing, try to fix your mistakes, like you don't need to make a capital letter after every start quote...EX: "m..my...my arms.. there covered..".. "Sister"? It's still the same sentence. Good writing, for just a boredom story. Keep practicing.
