It does not matter whether it continues to flow out of his body or is blocked. It will make him "unclean." Here is how his liquid body waste will make him "unclean."

" 'Suppose you are "clean." And suppose the man who has the flow of liquid waste spits on you. Then you must wash your clothes. You must take a bath. You will be "unclean" until evening.
Suppose you touch any of the things that were under him. Then you will be "unclean" until evening. Even if you pick up those things, you must wash your clothes. You must take a bath. You will be "unclean" until evening.
" 'Suppose the man who has the liquid flow touches you. And suppose he does it without rinsing his hands with water. Then you must wash your clothes. You must take a bath. You will be "unclean" until evening.
" 'Suppose the man has been healed from his liquid flow. Then he must wait seven days. He must wash his clothes. He must take a bath in fresh water. After that, he will be "clean."
" 'On the eighth day he must get two doves or two young pigeons. He must come to the Lord at the entrance to the Tent of Meeting. There he must give the birds to the priest.
The priest must sacrifice them. One is for a sin offering. The other is for a burnt offering. In that way the priest will pay for the man's sin in the sight of the Lord. He will do it because the man had a liquid flow.
" 'Suppose a man makes love to a woman. And suppose semen flows from his body and touches both of them. Then they must take a bath. They will be "unclean" until evening.
" 'Suppose a man makes love to that woman. And suppose blood from her monthly period touches him. Then he will be "unclean" for seven days. Any bed he lies on will be "unclean."
" 'Suppose blood flows from a woman's body for many days. And it happens at a time other than her monthly period. Or blood keeps flowing after her period is over. Then she will be "unclean" as long as the blood continues to flow. She will be "unclean," just as she is during the days of her period.
" 'Any bed she lies on while her blood continues to flow will be "unclean." It is the same as it is when she is having her period. Anything she sits on will be "unclean." It is the same as it is when she is having her period.
" 'The priest must sacrifice them. One is for a sin offering. The other is for a burnt offering. In that way he will pay for her sin in the sight of the Lord. He will do it because her flow of blood made her "unclean."
" 'You must keep the people of Israel away from things that make them "unclean." Then they will not die for being "unclean." And they will not die for making the place where the Lord lives "unclean." It is in the middle of the camp.' "

They apply to a woman who is having her monthly period. They apply to a man or woman who has a liquid flow. And they apply to a man who makes love to a woman who is not "clean."
