Well, I've heard of ways like saliva when coughing and sneezing.. But really, tears? Well, if it is inside us we can transmit it to someone else by only breathing the same air.. or just being in the same enclosed space and touching the same things.. That is how my friend got the virus. He was just for some minutes in the same room where previously was a patient and some days later he got fever and he did a
coronavirus antigen test and it was positive. So yeah, be careful everyone.. !
