Exposure risk calculator

A points-based read on your parasite exposure risk, weighing the factors that actually move the needle, travel, food, water, animals, and environment. Your answers stay in your browser.

Educational estimate only

This calculator weighs known risk factors, it does not detect or diagnose infection. High exposure risk does not mean you have a parasite, and low risk does not rule one out. Only testing can confirm.

However your risk lands, the best next step is the same: don't guess. If symptoms are present, get the right test. If not, focus on prevention.
