Visitor Essay by Kip Hansen — 19 November 2023
Valley Fever — which might typically be lethal and typically so innocuous as to be mistaken for a chilly or gentle flu — has now been added to the record of issues “attributable to local weather change”. Really, the actual declare is that the future unfold of Valley Fever, if it happens, might be attributable to local weather change as a result of “fashions”.
The paper is reported in an article within the Washington Put up, titled “An invisible killer” which was written by Joshua Partlow, Veronica Penney and Carolyn Van Houten and revealed Nov. 13 2023. The lede or sub-title is “A flesh-eating fungus is increasing its vary within the American West — and scientists suspect local weather change is driving the unfold”.
They first inform the story of a single man and his horrific encounter with Valley Fever. And it’s true that some individuals can get very sick with Valley Fever – however only a few.
The CDC says: “Valley fever, additionally referred to as coccidioidomycosis, is an an infection attributable to the fungus Coccidioides. The fungus is understood to reside within the soil within the southwestern United States and elements of Mexico and Central and South America. The fungus was additionally just lately present in south-central Washington. Folks can get Valley fever by respiration within the microscopic fungal spores from the air, though most individuals who breathe within the spores don’t get sick. Normally, individuals who get sick with Valley fever will get higher on their very own inside weeks to months, however some individuals will want antifungal remedy. Sure teams of individuals are at greater threat for turning into severely sick. It’s tough to stop publicity to Coccidioides in areas the place it’s widespread within the surroundings, however people who find themselves at greater threat for extreme Valley fever ought to attempt to keep away from inhaling giant quantities of mud in the event that they’re in these areas.”
Please take notice: Nowhere, in any description outdoors of the MSM (all of which appear to be quoting the Washington Put up), is the fungus that causes Valley Fever known as a “flesh-eating fungus”. There’s a situation referred to as Necrotizing Fasciitis however it’s attributable to micro organism (Strep A is the almost certainly wrongdoer), not a fungus and positively not Coccidioides. A search of the CDC web site returns no cases of any flesh-eating fungal infections.
Actually, our hard-working workforce of journalists are reporting, with extravagance, a few research achieved by Morgan Gorris in 2019. Her College of California, Irvine net web page says: “I research coccidioidomycosis, also referred to as valley fever, an infectious illness attributable to the inhalation of airborne fungal spores. As our local weather adjustments, the atmospheric transport patterns and liveable surroundings of this species is hypothesized to shift, inflicting new populations to be uncovered to the illness. I’m fascinated about relating previous epidemiological developments of valley fever circumstances to local weather and environmental components which affect the life cycle of the fungi. I then use these relationships to forecast what new populations could also be vulnerable to contracting valley fever in response to future local weather change.”
Her research “Growth of Coccidioidomycosis Endemic Areas in america in Response to Local weather Change” naturally used RCP8.5 to “predict the local weather” of the American West out to 2095, based mostly on precipitation and temperature, and produced this animated gif as an example the “hypothesized unfold” of Valley Fever.
The right down to earth fact is that scientists and medical doctors don’t know no matter how broadly the fungus that causes Valley Fever might be discovered within the western elements of america. Or precisely what the pure reservoir of the fungus is that causes Valley Fever when its spores or fungus fragments are inhaled by people. They solely know the place the fungus is discovered by the place Valley Fever circumstances are discovered. Within the final decade medical doctors had been shocked to discover a cluster of Valley Fever circumstances in japanese Washington State that had been confirmed to have been contracted regionally, and never in Southern California or Arizona. The fungi that trigger Valley Fever are Coccidioides immitis and Coccidioides posadasiii. In america, scientists have discovered C. immitis primarily in California, in addition to Washington State. C. posadasii is discovered primarily in Arizona, in addition to New Mexico, Nevada, Utah, Texas, and parts of southern California.
When the phrase reservoir is used with a disease-causing issue (comparable to a germ, micro organism, virus) this implies “a number of epidemiologically related populations or environments during which the pathogen might be completely maintained and from which an infection is transmitted to the outlined goal inhabitants” [ source ]. In different phrases, the place the pathogen lives when earlier than it’s transmitted to and infects a human (on this case). For malaria, it’s typically incorrectly believed that mosquitos are the reservoir however this isn’t true. People themselves are the reservoir for malaria (and dengue and others) and mosquitos are solely the vector.
For Valley Fever, an surroundings of a specific kind appears to be the reservoir: the recent, dry, dusty soils discovered within the dry areas of the American West.
The variety of Valley Fever circumstances is rising:
Crucial components for Valley Fever stats are: Elevated surveillance (many states require reporting circumstances, many don’t) which additionally means extra medical doctors trying and testing for Valley Fever; and the variety of individuals exposing themselves to Valley Fever – extra individuals four-wheeling and off-roading within the deserts of the American West. The variety of circumstances outdoors of Arizona, California, Nevada and Utah is so small it’s tough to see it within the CDC chart (above).
We all know that the Valley Fever fungus is discovered within the dry soils of the American southwest, extra simply discovered within the holes that rodents dig and reside in: whether or not or not the rodents have any relationship to the fungus or if the rodents are simply digging and exposing the underground rising fungus just isn’t recognized. Valley Fever was first discovered within the San Juaquin Valley of California, largely among the many farm employees there, who’re almost certainly to be uncovered to mud within the fields. Contraction of the illness is normally related to inhalation of superb soil mud, and extra so, it appears, when the soils re-dry after heavy rains.
The concept Valley Fever may have an expanded vary got here from a confirmed cluster of circumstances in japanese Washington State, a child landed on his face within the dusty desert from his off-road cycle and inhaled a lungful of mud. He developed Valley Fever. Since that case was confirmed, extra individuals had been examined.
In 2007, Valley Fever circumstances had been reported within the following areas:
The U.S. CDC shares this map of the vary of Coccidioides:
So, there we’ve got it. The CDC is aware of the place Valley Fever circumstances happen, and maps the suspected present vary of Coccidioides – Darker shaded “areas the place Coccidioides is extra more likely to reside”. This map was developed by monitoring Valley Fever circumstances, and never by soil testing for the fungus. Diagonal shading exhibits the potential vary of Coccidioides, the place the fungus is perhaps discovered if the soils had been examined, however even then, it could be discovered solely by probability, as it’s within the areas it’s recognized to be extant. The CDC states explicitly: “These maps present CDC’s present estimate of the place the fungi that trigger coccidioidomycosis (Valley fever) reside within the surroundings. These fungi aren’t distributed evenly within the shaded areas, may not be current all over the place within the shaded areas, and may also be outdoors the shaded areas.”
As we will see beneath, the Gorris projection for 2095 could be very near the CDC assertion of the place Coccidioides already is suspected of present:
Backside Line:
For those who reside in Arizona or the Joaquin Valley of California and are a devoted desert dust-eater (four-wheeling, off-road Jeeping, prospecting in dusty soils, or doing archaeology out West), you want to pay attention to Valley Fever and put on protecting respiration gear to maintain the mud out of your lungs.
The fungi Coccidioides is perhaps discovered within the soils anyplace west of the Rockies and medical doctors and nurses ought to concentrate on the potential for Valley Fever circumstances.
The remainder of us can ignore the alarmist press on it.
Coccidioides is NOT a flesh-eating fungi. (It will possibly trigger a rash.)

Authors Remark:
If this story (nicely, a wise, non-alarmist model of it) had appeared within the Phoenix Solar or any native southwestern newspaper, it could be a public good, reminding individuals of the potential for Valley Fever and its causes and signs. Its look within the Washington Put up, “flesh-eating fungus”, can solely be propaganda.
COP28 hysteria on local weather change – which, apparently, causes every part unhealthy and nothing good.
I spent a number of my youth within the deserts of California, Nevada and Arizona – didn’t get Valley Fever – did get Cat Scratch Fever although.
Thanks for studying.
