A well-fed, ill-mannered ten year old boy wiping his snotty nose on his hands and wanting to shake yours is not exactly a leper.
Being Catholic doesn’t mean jumping in front of a speeding train.
My daughter’s father in-law is immuno supressed. He has a donated organ and takes anti-rejection drugs. If he gets a cold or flu it is a serious matter and he gets ill often. The normal healthy person might get a cold from the snotty kid and have some temporary discomfort. For the very elderly their next cold could be their last.
A friend of mine specializes in anti-terrorism. Among other things he studies how bioterrorism might be enacted and countered. Some years ago he spoke in front of a group of about 300 people, consisting of ambasadors, the vice-president at the time, various administration federal officials and secretaries. He spoke about how pathogens might deliberately be spred quickly through any population. Seceretly, he put a chemical on his right hand before entering the hall. People he knew and to whom he was introduced shook his hand. They shook the hands of others. At the conclusion of his talk he told the audience that on the way out the door they should put their hand under a black light to see if they were infected, or came in contact with what could have been a deliberate attempt to infect them with some deadly pathogen. The harmless chemical was visible under the light.
Every person in the room lit up including the VP of the United States and his secret service body guards there to protect him.
There is a difference between being a germophobe and being prudent.
Another friend is an usher at a local parish. He knows everyone and greets everyone with a handshake. When I go there I am glad to see him and shake his hand, but am also aware that this means I have indirect contact with numerous sick people. I don’t carry sanitizer, but accept the risk. Today I have a bit of a sore throat coming on and slightly swollen glands. Should I be physically contacting my fellow parishoners? When people greet me and put their hand out and I am sick I tell them not to shake my hand, because I don’t want to make them sick. Many will grab my hand anyway and say they do not care and go off and greet others. Is that prudent?
My daughter is an RN working in a hospital in labor and delivery. She is trained to wash her hands every time she leaves a patient’s room, which could be dozens of times in a 12 hour shift, and her patients are not even sick.
It seems like we take all of this information about how disease is spred and how the spred can be prevented and throw it out the window when we go to Church.
So what if the snotty kid is not a leper. He is infectous and his parents should keep his nose wiped and keep him away from others until he is well, or better yet, keep him home.
