Okay so last night I washed my hands at supper and took a shower later. Well,I woke up last night picking my nose on accident!! I must have been dreaming!! I'm really worried about norovirus! I know I washed my hands and took a shower, but I ended up touching my room doorknob plus the bathroom door knob and my phone, before I put my hands in my nose!! Can I get norovirus from this?
