Heartland Virus Cases Increase
The Heartland Virus, a new arthropod-harbored contagion, is drawing increased attention from hospitals and public health officials. As it stands now, five new cases have been documented in different parts of Missouri, and a dozen cases have been documented worldwide.

The Heartland Virus is contracted when the Lone Star tick, endemic to the plains region of America (thus the name), attaches to an individual and begins drinking the blood. While drinking, the tick regurgitates some fluid to help dissolve skin layers to make feasting easier. This regurgitated fluid contains the virus, which spreads in the blood stream as the tick feeds. Other tick borne illnesses, such as Lyme disease, Rocky Mountain Spotted Fever, and tularemia, are spread in the same manner.
Symptoms begin with fever and general malaise. As the disease progresses symptoms include headaches, muscle aches, diarrhea, loss of appetite, or nausea, with decreases in leukocytes, or cells that help fight infection. Most patients require hospitalization, where they fully recover. Only one patient has died since the virus was discovered in 2012.
Currently there are no specific treatments for Heartland Virus infections, mainly because the limited number of cases, low lethality, and recent discovery of the disease have not given scientists and health care workers time and resources to develop a substantial cure. To prevent acquiring Heartland Virus, or any tick-borne infection, the CDC recommends four major steps be taken:
- · Use insect repellents
- · Wear long sleeves and pants
- · Avoid bushy and wooded areas
- · Perform thorough tick checks after spending time outdoors
