Well, the city of Santa Ana, CA with a 75% illegal alien population has at least one ‘resident’ with typhus and how did they explain it? The typhus victim lived near a school that has feral cats that carry fleas that PROBABLY carry typhus. They made this announcement before any tests were conducted to substantiate their claim. Seems they were in a hurry to pin the reason for this outbreak on something OTHER than an illegal immigrant from Mexico.
To be fair the cat-flea vector is more common for single cases of typhus.
Human to human transmission is vectored by infected lice and is generally epidemic rather than single cases.
