Scientists warn of invasive longhorned tick carrying debilitating Ehrlichiosis infection

An invasive tick species is creeping its way into more parts of the country as warming temperatures help it spread a little-known infection that can leave people with debilitating symptoms and, in rare cases, dead. In May, scientists at the Connecticut Agricultural Experiment Station in New Haven discovered for the first time that the longhorned tick had become a carrier for the bacterium that causes the Ehrlichiosis infection. With cases already on the rise, that was a big cause of concern.
