What is the typical incubation period for piroplasmosis in horses?

Incubation period for piroplasmosis in horses is the interval from the tick-borne infection to when clinical disease and detectable parasitemia appear. After a horse is bitten and the parasite begins its life cycle, it takes several days to weeks for the parasite to multiply to levels that cause fever, anemia, and other signs. The typical timeframe is about 5 to 28 days, which best fits the usual course observed in equine piroplasmosis. Shorter intervals like 1–2 days are too rapid for the parasite to establish infection, while much longer periods (30–60 or 60–90 days) are not the typical incubation window for this disease. Individual variation in tick bite intensity, parasite species, and host immunity can shift this a bit, but 5–28 days remains the standard expectation.
