Patient discussion about communicable disease

Q. Is psoriasis infectious? Last week I and my friends from high-school went to the pool. One of my friend has psoriasis on his back, and when the lifeguard noticed it he asked him to leave the pool because he has skin disease that may spread to the other people swimming in the pool. We told him it is psoriasis and not some fungus, but he told us that psoriasis is also infectious. Is that true? Can psoriasis infect people who come in touch with people with psoriasis? Can I go swimming with him or should be more cautious?

A. It is right that psoriasis is not a contagious skin condition. But your friend should take care. However keeping skin humid is better for Psoriasis patients as I recently read these tips at

Q. Is leukemia contagious? A friend of mine got leukemia (blood cancer), can I get it from him if he bleeds and I touch the blood? Like HIV I mean.

A. No, you don't have to be afraid, no chance of that. Your friend will need you to pass this terrible illness. So I recommend learning a bit about leukemia so you understand it better and won't avoid your friend.

Q. Is psoriasis contagious? My wife got psoriasis and I don’t want to get infected…

A. Psoriasis itself, as was written above, isn't contagious, i.e. if someone has psoriasis he or she can't transmit it to you. However, there is a form of psoriasis called psoriasis guttate that is associated with infection of the throat by a bacterium called streptococcus (which is contagious), so in some way it is contagious.
