Bartonella seldom meets or at all is absent in a frigid climate which is stood hardly by fleas - disease carriers, however it is quite widespread in the warm, wet area. Bacteria which are in blood of a cat within several months after infection are usually harmless to the majority of cats, and the infected cat does not show any symptoms. Kittens (cats is younger than one year) more often than adult cats, are an infection carrier.
Bartonella can infect people whom it scratched or (less often) the cat bit. The disease  is not transmitted from the person to the person.
