Heartland virus (HRTV) is spread to people by the bite of an infected tick. Most cases have been reported from states in eastern, southeastern, and south-central U.S.
The lone star tick (Amblyomma americanum) is suspected to be involved with spread of the virus.
Although there are no specific treatments for Heartland virus, the lone star tick can also carry bacteria such as Ehrlichia which can be treated with antibiotics.
There have been cases where a person was infected with both.

Transmission
Based on human case reports and laboratory studies, the Lone Star tick (Amblyomma americanum) is primarily responsible for transmitting Heartland virus.
The Asian Longhorn tick (Haemaphysalis longicornis) has also been shown to be a potential transmitter in the laboratory.
Symptoms
Symptoms of Heartland virus include fever, fatigue (feeling tired), decreased appetite, headache, nausea, diarrhea, and muscle or joint pain.
These symptoms can also be seen with tick-transmitted bacterial infections such as Rocky Mountain spotted fever and ehrlichiosis.
