Today my friend woke up with a cold, but felt it was okay to come over. He was sneezing, coughing, and constantly wiping his nose with a tissue he held in his hand. After a few hours, I felt it was best he go home. I wiped down my surfaces, remotes, phone, ect. with disinfecting wipes. My concern is, he also used his hand to pet my cat through out the time he was here. He used the same hand to pet my cat that he also used to hold his tissue. Am I at risk of catching a cold if I also pet my cat?
