What is babesiosis?
Babesiosis refers to a malaria-like illness caused by the parasite Babesia. It is transmitted from animals to humans by various ticks. Babesia species of protozoan parasites infect cattle, horses, dogs, cats, and mice – humans are opportunistic hosts. Humans get this zoonotic infection incidentally, when bitten by adult ticks or nymph. Individuals with babesiosis may not show any symptoms. However, babesiosis can severely affect the elderly or other people without spleen with a weak immune system. It may even lead to death.
