Mold Causes Valley Fever in the Southwest

There is a mold that exists in the southwestern United States, different areas of South America, and the deserts of Mexico that the majority of people are not aware of when they visit the area. The people the most at risk for coming into contact with this mold are construction workers and archeologists, because they dig around in the soil where this mold tends to be found. What is it called and just how dangerous is it really?

Coccidioides immitis causes a skin disease that has been referred to as “Valley Fever” by some, but as Coccidioidomycosis to physicians. The features of this skin disease are typically rashes, coughing, myalgia, rashes, and headaches. Myalgia is synonymous with “muscle pain” and this can be a sign or symptom of many other different kinds of diseases, not just Valley Fever. The usual cause of myalgia is the over-use of a specific muscle or possibly an entire set of muscles. If a person does not have a medical history of overworking or accidents, then the myalgia is probably being caused by a bacterial or even a viral infection. If it is present in a person chronically, then it could possibly be a sign of some deficiency in the person’s nutrition.

The disease is known to be endemic in the states of New Mexico, California, and Arizona.

The most common cause of C. immitis exposure is due to the digging or disturbing of soil that has been contaminated. For the mold spores to get into the air and allow you to inhale them, this contaminated soil typically needs to be wet and recently, in order for archeologists to be able to dig in soil in the southwestern United States, they have ordered the soil be saturated with water first to avoid this exposure. This has been put into practice not only with archeologists, but also any other occupation that involves digging into the soil. Soil can also be stirred up due to natural disasters such as earthquakes or dust storms.

Those at the risk for developing the most serious aspects of the disease can include those who are pregnant and in their third trimester, African Americans, Asians, and anyone with a weakened immune system, such as those who have HIV or AIDS. Severe pulmonary disease could develop in these individuals in addition to the skin rashes, fever, and other symptoms that are associated with Valley Fever.
