Is it safe to go back to school yet???

After being home sick from school for 4 days Zach is ready to feel better and get back to his "social life". Started off with a little cough and it turned into a massive painful cough, sore throat, headache and fever. He has never missed more than 1 day of school because of being ill but he couldnt go with a fever so he slept a ton and took like 3 baths a day to warm up. I have not washed more towels in all my life. Any how finally he is feeling like himself today. Thanks goodness because with all the sick stuff going around I was getting a little worried about the kido. Now hopefully I have cleaned well and disinfected everything so nobody else gets it.
