Fleas are capable of transmitting which of the following to humans?

• A. Bacterial infections
• B. Heartworms
• C. Tapeworms
• D. Lice

Answer: (C)

Fleas are known to be vectors for various parasites and diseases, making them significant in terms of public health. The correct answer relates to tapeworms, which are specifically linked to flea infestations. When a host animal ingests a flea that carries tapeworm larvae, it can become infected with the parasites. This is particularly relevant in pets, such as cats and dogs, which can then indirectly transmit tapeworms to humans, especially young children who may accidentally ingest fleas during play. While fleas can transmit certain bacterial infections, such as the bacteria responsible for the plague, the relationship with tapeworms is more direct and leads to infection through ingestion of the flea. Heartworms are a type of parasite transmitted by mosquitoes, not fleas, and lice are different parasites altogether that infest the hair or skin of mammals and birds, not transmitted by fleas. This specificity highlights why tapeworms are the most relevant concern when it comes to flea-borne transmission to humans.
