The short answer is: YES, human beings can carry fleas from one house to another.
The bugs will hitchhike your clothes, shoes, skins, or hair.
Unlike pets’ skin, human skin has no hair/fur, and thus fleas will jump off to a furry area when you get home.
How long do fleas live in your house?

How do fleas spread in the house?
Fleas and Flea InfestationsFleas don’t have wings, but they have flat bodies and strong legs, which allow them to jump long distances. They travel by jumping from one person or animal to another. Your home may become infested with fleas if your pet brings these parasites into your house.
How do you not bring fleas home with you?
Keep Your Home Clean.So vacuum at least once a week, and more often if you spot fleas. When you vacuum, don’t just cover the center of the room. Fleas avoid high-traffic areas, so be sure to hit baseboards, under furniture, under cushions, and anywhere your pets sleep or spend time.
