The fungus that causes Valley fever lives in the soil in the southwestern United States, south-central Washington State, and parts of Mexico and Central and South America. The maps on this page show the following topics:
•Approximate areas where we know or suspect the fungus lives
•Places where Valley fever outbreaks have happened
•Cases of Valley fever detected by public health surveillance
Scientists are still learning about where the fungus that causes Valley fever can be found.

These maps show the approximate areas where we know or suspect the fungus that causes Valley fever lives. These are considered endemic areas for Coccidioides, the fungus that causes Valley fever. 1–6 Much of what is known about where the fungus lives in the southwestern United States is based on skin testing studies performed in the late 1940s and early 1950s. 2 The U.S. map also shows the locations of several outbreaks and locations of Valley fever cases acquired outside of the areas identified by those studies. Coccidioides might also live in similar areas with hot, dry climates that are not shaded on the map.
These maps show CDC’s current estimate of where the fungi that cause coccidioidomycosis (Valley fever) live in the environment. These fungi are not distributed evenly in the shaded areas, might not be present everywhere in the shaded areas, and can also be outside the shaded areas. Darker shading shows areas where Coccidioides is more likely to live. Diagonal shading shows the potential range of Coccidioides.

Most cases of Valley fever are not part of an outbreak. However, Valley fever outbreaks linked to a common source do occasionally occur, particularly after events that disturb large amounts of soil. This map shows the locations of 40 Valley fever outbreaks that happened during 1940–2015. 7 Some of these outbreaks happened in places where scientists did not expect the fungus to live. Investigating Valley fever outbreaks helps public health officials understand:
•Where the fungus lives,
•Activities that may make someone more likely to get Valley fever, and

Sep 15, 2022 · Rocky Mountain spotted fever (RMSF) is a life-threatening tick-borne disease documented in North, Central, and South America. In California, RMSF is rare; nonetheless, recent fatal cases highlight ecological cycles of the two genera of ticks, Dermacentor and Rhipicephalus, known to transmit the disease. These ticks occur in completely different ...

Feb 16, 2024 · Rocky Mountain spotted fever (RMSF) is a potentially lethal, but curable tick-borne disease, which was first described in Idaho in the 19 th century. In 1906, Howard Ricketts demonstrated that RMSF was an infectious disease transmitted by ticks [ 1 ].
