Valley Fever Causes

Valley Fever Causes-various aspects-

Valley fever, also known as coccidioidomycosis, is caused by inhaling spores of the fungus Coccidioides. These spores, which are microscopic and can be carried by wind, reside in the soil of certain desert and semi-arid regions, particularly in the southwestern United States and parts of Central and South America. When these spores are inhaled, they can lodge in the lungs and cause an infection, which may manifest as flu-like symptoms or more severe complications in some individuals.

Here’s a more detailed explanation:

Fungal Infection:

Valley fever is a fungal infection caused by the Coccidioides fungus, specifically Coccidioides immitis and Coccidioides posadasii.
Inhalation of Spores:
The primary way to contract valley fever is by inhaling spores from the soil when it’s disturbed by activities like construction, farming, or even strong winds.
Geographical Distribution:
The Coccidioides fungus thrives in specific geographic regions, particularly in the southwestern United States (Arizona, Nevada, Utah, New Mexico, California, Texas, and Washington) and parts of Mexico, Central, and South America.
Symptoms:
Many individuals who inhale Coccidioides spores experience no symptoms or have mild, flu-like symptoms that resolve on their own. However, in some cases, the infection can cause more serious symptoms, such as fever, cough, headache, chest pain, fatigue, and joint pain. In rare cases, the infection can spread to other parts of the body, causing complications like meningitis.
Risk Factors:
Factors that increase the risk of developing valley fever include residing or traveling to endemic areas, engaging in outdoor activities that involve soil disturbance, having a weakened immune system (due to HIV, AIDS, or certain medications), and certain ethnicities (Filipino, Hispanic Amerindian, Native North American, and Asian individuals may have a higher risk of developing symptomatic infections).

Valley fever occurs when an individual breathes in spores from specific fungi. The fungi responsible for valley fever — Coccidioides immitis or Coccidioides posadasii — reside in the soil located in regions of Arizona, Nevada, Utah, New Mexico, California, Texas, and Washington. It is named after California’s San Joaquin Valley.

Overview

Valley fever is a fungal infection caused by coccidioides (kok-sid-e-OY-deze) organisms. It can result in symptoms and signs such as fever, cough, and fatigue.
Two species of coccidioides fungi are accountable for causing valley fever. These fungi are usually found in soil in specific regions. The spores of the fungi can become airborne due to soil disturbances initiated by activities such as farming, construction, and wind.
People may subsequently inhale the fungi into their lungs. The fungi can lead to valley fever, which is also known as acute coccidioidomycosis (kok-sid-e-oy-doh-my-KOH-sis). Mild cases of valley fever typically resolve without treatment. In more serious situations, healthcare providers manage the infection with antifungal therapies.

Causes

Valley fever results from an individual inhaling spores from specific fungi. The fungi responsible for valley fever — Coccidioides immitis or Coccidioides posadasii — reside in the soil in areas of Arizona, Nevada, Utah, New Mexico, California, Texas, and Washington. It is named after California’s San Joaquin Valley. The fungi are also frequently located in northern Mexico and Central and South America.

Similar to many other fungi, coccidioides species have a complicated life cycle. In the soil, they develop as a mold with elongated filaments that detach into airborne spores when the soil is disturbed. An individual can subsequently inhale these spores.

The spores are incredibly tiny and can be propelled over long distances by the wind. Once they enter the lungs, the spores replicate, perpetuating the disease cycle.

Risk factors

Risk factors for valley fever include:

Environmental exposure. Any individual who breathes in the spores that lead to valley fever faces a risk of infection. Those residing in regions where the fungi are prevalent — particularly individuals who frequently engage in outdoor activities — experience an elevated risk.

Also, individuals employed in occupations that expose them to dust are at the highest risk — including construction, road and agricultural workers, ranchers, archaeologists, and military personnel during field operations.

Race. For reasons that are not fully comprehended, individuals of Filipino and African descent are more prone to developing serious fungal infections.
Pregnancy. Expecting mothers are at risk of more severe infections if they contract the infection during the third trimester. New mothers are at risk immediately after the birth of their babies.
Weakened immune system. Anyone with a compromised immune system has an elevated risk of serious complications. This encompasses individuals living with acquired immunodeficiency syndrome (AIDS) or those receiving treatment with steroids, chemotherapy, and anti-rejection medications following transplant surgery. Individuals with specific autoimmune diseases, such as rheumatoid arthritis or Crohn’s disease, who are undergoing treatment with anti-tumor necrosis factor (TNF) drugs, are also at a higher risk of infection.
Diabetes. Individuals with diabetes may face a heightened risk of severe lung infections.
Age. Elderly individuals are more likely to contract valley fever. This may be attributed to their immune systems being less effective or due to the presence of other health conditions impacting their overall well-being.

Complications

Certain individuals, especially pregnant women, those with weakened immune systems — including persons with human immunodeficiency virus (HIV)/AIDS — and individuals of Filipino or African ancestry are at a heightened risk of encountering a more severe form of coccidioidomycosis.
Complications of coccidioidomycosis may encompass:
Severe pneumonia. Most people recover from pneumonia related to coccidioidomycosis without complications. However, some, particularly individuals of Filipino and African descent as well as those with compromised immune systems, might become seriously ill.
Ruptured lung nodules. A small percentage of people develop thin-walled nodules (cavities) inside their lungs. Many of these eventually heal without causing any problems, but some may rupture, resulting in chest pain and breathing difficulties. A ruptured lung nodule might require tube placement in the area surrounding the lungs to remove the air or surgical intervention to repair the damage.
Disseminated disease. This denotes the most serious complication of coccidioidomycosis, though it is uncommon. If the fungus spreads throughout the body, it can result in complications such as skin ulcers, abscesses, bone lesions, severe joint pain, inflammation of the heart, urinary tract issues, and meningitis — a potentially fatal infection that affects the membranes and fluid encasing the brain and spinal cord.

Prevention

There is currently no vaccine available to prevent valley fever.
If you live in or visit areas where valley fever is common, take sensible precautions, especially during the dry season after a rainy period when the risk of infection is higher.
Consider these recommendations:
Wear a mask.
Avoid extremely dusty areas, such as construction sites.
Remain indoors during dust storms.
Moisten the soil before digging in it, or avoid soil if you are at an elevated risk of infection.
Ensure doors and windows are tightly closed.
Clean skin injuries with soap and water.
