Tell me everything I need to clean/disinfect after being sick for a month?

Keep a can of lysol with you for a day or two. Spray everything that you touch. Toss your toothbrush for a new one and wash your bedsheets in hot water. That should be enough. It's not likely that you'll get sick from the same germs that made you sick the first time. It's the germs outside your home you should be more concerned about.
