In 2015, there was an abrupt rise in Sonora cases with 80 fatal cases. [8] Approximately 0.5% of people who are infected die as a result. The rash has a centripetal, or "inward" pattern of spread, meaning it begins at the extremities and courses towards the trunk. Cases of Heartland virus have been identified in the Midwestern and southern United States, including Arkansas.

The bacterium is spread to humans through the bite of infected ticks, and so the disease is most common in months where ticks are active, such as summer. RMSF became reportable in North Dakota in 1944. Other tick species have been shown to be naturally infected with R. rickettsii or serve as experimental vectors in the laboratory. The characteristic rash observed in Rocky Mountain spotted fever is the direct result of this localized replication of rickettsia in blood vessel endothelial cells. I'm starting to wonder if these issues aren't related. [20], Studies have suggested that rOmpB is involved in this process of adhesion and invasion.

Rickettsia rickettsii initially infect blood vessel endothelial cells, but eventually migrate to vital organs such as the brain, skin, and the heart via the blood stream. Sometimes, when a tick feeds on a host it will pass along pathogens that can cause disease such as bacteria, viruses, and protozoa. After the tick develops into the next stage, the R. rickettsii may be transmitted to the second host during the feeding process. Verified cases reported from other US states are usually associated with travel to states with high rates of infection. [21] The bacteria are then taken up by the neighboring cell in a double membrane vacuole that the bacteria can subsequently lyse, enabling spread from cell to cell without exposure to the extracellular environment. There are no vaccines to prevent or medications to treat Heartland virus infections.The majority of Heartland virus patients required hospitalization but were able to return to their normal health in the weeks and months following their discharge.
