How to spell INFECTEDS correctly?

The word "infecteds" is not a correct spelling. If you mean to refer to multiple infected individuals, a correct form would be "infected people" or simply "infected". Alternatively, if you are discussing a specific group affected by a disease, you might use a more specific term such as "affected population" or "infected patients."
