If it covered him completely all at once — [if it was] from [a state of] taharah, he is tamei; — [if it was] from [a state of] tumah, he is tahor. One who becomes tahor from a status of confinement is absolved from letting his hair grow, from rending his garments, from shaving, and from the birds. [One who becomes tahor] from a state of confirmation is obligated to [do] all of them. Both cause tumah upon entering [a house].

One who comes completely white but has a patch of living skin the size of a lentil [whose nega] covered him completely and then the extremities reverted, R’ Yishmael says: It is like the reverting of the extremities of a large baheres. R’ Elazar ben Azaryah says: It is like the reverting of the extremities of a small baheres.
