I just managed to avoid a bug that my cousin had when I went to her house, now I'm going through YET another panic attack. I accidentally brushed my mouth against a christmas decoration that has been sitting in dust for one year. My question is, could I have caught anything? I washed my mouth with mouthwash, brushed my teeth and spat out the saliva before I swallowed after brushing my mouth against the decoration. Please help, I'm getting reeally nervous.
