Cats and rats.
Snort.
Per the CDC: “Transmission
Typhoid fever and paratyphoid fever are transmitted commonly through the consumption of drinking water or food contaminated with the feces of people who have typhoid fever cases or are chronic carriers.”
Typhus is a different disease than typhoid although understandable people, incl me, get the two confused.
Apparently there are different types of typhus. There is is flea-borne variety of typhus which IS spread by rats, raccoons, feral cats, etc. It is not considered very life threatening, clearing up after a round of antibiotics. The fact that there are rats and the like in L.A. is a consequence of people living in a filthy manner. The feral cats are an unfortunate result of negligent uncaring people who fail to spay or neuter their cats and who toss them into the street like refuse instead of cherishing them for the loving pets they are.
