• Most fungi are harmless, but some types can make you sick. Coccidioidomycosis, also called valley fever, is an illness caused by a fungus that is common in some parts of the United States.

What is Valley Fever

• Valley fever is caused by Coccidioides, a fungus that lives in soil in the southwestern United States and parts of Mexico, Central America, and South America.

• Inhaling the airborne fungal spores can cause an infection called coccidioidomycosis, which is also known as “cocci” or “valley fever.”

Valley fever cannot spread from person to person

• Most people who are exposed to the fungus do not get sick, but some people develop flu-like symptoms that may last for weeks to months

• In a very small proportion of people who get valley fever, the infection can spread from the lungs to the rest of the body and cause more severe conditions, such as meningitis or even death.

10 Things You Should Know About Valley Fever, According to the CDC

1. Valley fever is caused by a fungus that lives in the environment.

• There are an estimated 1.5 million species of fungi on Earth, but only about 300 of them can make people sick. Valley fever is a respiratory disease caused by a fungus called Coccidioides. Valley fever is becoming increasingly common, and it can be debilitating and costly. Nearly three-quarters of valley fever patients miss work or school because of their illness, for an average of two weeks, and more than a third of patients need to receive care in the hospital.

1. Valley fever is caused by a fungus that lives in the environment.

• The fungus Coccidioides lives in soil and dust in the southwestern United States and parts of Mexico, Central America, and South America. People get valley fever by breathing in the microscopic, airborne fungal spores. Sometimes, the number of people who get valley fever increases after there have been weather-related events that stir up more dust than usual, such as earthquakes or dust storms.

2. Valley fever is not contagious.

• Valley fever does not spread between people.

3. Symptoms of valley fever are usually similar to the flu.

• Approximately 40 percent of people who get the fungal infection do not show any symptoms. In the other 60 percent, valley fever can cause flu-like symptoms, including:

• Fever• Cough• Fatigue• Headache• Muscle aches• Joint pain

• The symptoms of valley fever typically appear between one and three weeks after someone inhales the fungal spores. In many people, the symptoms will disappear in a few weeks. However, in severe cases, the infection can cause chronic pneumonia, and the symptoms can last for years.

• In less than 1 percent of people who get valley fever, the infection can spread from the lungs to the rest of the body, causing meningitis (spine and brain infection) or infection in the bones and joints.

4. Valley fever is common in the southwestern United States.

• In the U.S., over 65 percent of all valley fever cases occur in Arizona, and 30 percent occur in California. Most other cases occur in Nevada, Utah and New Mexico. Valley fever is a risk for people who live in these states but also for people who visit there.

• Studies have shown that in some areas where valley fever is very common, such as southern Arizona, valley fever causes an estimated 15 percent to nearly 30 percent of all community-acquired pneumonias, but that less than 15 percent of patients with pneumonia symptoms are tested for valley fever. This suggests that there may be many more people with the disease than are reported.

5. Reported cases are increasing.• Some researchers estimate that

each year the fungus infects thousands more people, many of whom are sick without knowing the cause or have mild cases that aren't detected. In 2011, the most recent year for which there is data, more than 20,000 cases of valley fever were reported in the United States, and cases increased by about 15 percent each year from 1998 to 2011. Some researchers hypothesize that many milder cases go undiagnosed, which may mean that the reported cases are just the tip of the iceberg.

• The increase could be because of:• More people exposed to the

fungus because of increased travel or relocation to the southwestern United States

• Changes in the way cases of valley fever are being detected and reported to public health officials, or

• Changes in factors such as temperature and rainfall, which can affect the growth of the fungus in the environment and how much of it is circulating in the air.

6. Anyone can get valley fever.

• Anyone can get valley fever if they live in or have visited an area where the fungus Coccidioides lives, especially southern Arizona or California's Central Valley. Although people of any age can get valley fever, it is most common among older adults, particularly those ages 60 and older. People who have recently moved to an area where the disease naturally occurs are at higher risk for infection.

7. Some people are at higher risk for developing the severe form of valley fever.

• Groups of people who are more likely to develop the severe form of valley fever or develop an infection that spreads beyond the lungs include:

• African Americans• Asians• Pregnant women, particularly those in their third trimester

• People with weakened immune systems, such as those who have had an organ transplant or who have HIV/AIDS– Alpha1 Antitrypsin Disorder

• NOTE: The reasons why some racial groups are at higher risk are not completely understood but may have to do with genetics.

Alpha1 Antitrypsin Disorder

• Alpha-1 antitrypsin deficiency is an inherited disorder that may cause lung disease and liver disease. The signs and symptoms of the condition and the age at which they appear vary among individuals.

• People with alpha 1 antitrypsin def. have difficulty dealing with contaminants in their lungs and are therefore at an extremely high risk level for the sever form of Valley Fever

• People with alpha-1 antitrypsin deficiency usually develop the first signs and symptoms of lung disease between ages 20 and 50. The earliest symptoms are shortness of breath following mild activity, reduced ability to exercise, and wheezing. Other signs and symptoms can include unintentional weight loss, recurring respiratory infections, fatigue, and rapid heartbeat upon standing.

8. Some people will need antifungal treatment.

• In some people who get valley fever, the infection will go away on its own in a few weeks. However, antifungal treatment is recommended for certain patient groups, such as those at high risk for developing the severe forms of the disease. Because the symptoms of valley fever can be similar to those of other respiratory diseases, patients often experience delays in getting tested and receiving treatment, if they need it.

• EARLY DIAGNOSIS CAN:

• Reduce the amount of time and money spent looking for an alternative explanation for the patient's illness

• Avoid the use of unnecessary antibiotics, and

• Help alleviate patient anxiety about an unknown illness.

9. It can be difficult to avoid the fungus that causes valley fever.

• In areas where valley fever is common, it's difficult to completely avoid exposure to the fungus that causes valley fever. There is no vaccine to prevent the infection, although researchers are working to develop a vaccine. People with weak immune systems or who are at high risk for developing the severe form of the disease for another reason should consider trying to reduce their exposure to the fungus by limiting activities that disturb soil or generate dust, such as digging or excavation, in areas where the fungus lives.

10. Awareness is key.

• More awareness about valley fever among the general community and among healthcare providers is needed. Increased awareness could help avoid missed diagnoses. For example, one study showed that valley fever patients who knew about the disease before visiting a doctor were more likely to ask to be tested and were diagnosed sooner than patients who didn't know about the disease

10. Awareness is key.

• Health care providers should be aware that the symptoms of valley fever are similar to those of other common respiratory illnesses and should consider testing for valley fever in patients with flu-like symptoms who live in or have traveled to an area where it is common. People who have symptoms of valley fever and live in or have visited an area where the fungus is common should ask their doctor to test them for the disease.

Areas Where Fever Can be Found

E Light Policy

disorders it you are required to report this to your supervisor that you we can take measures to protect you.

E Light Policy

• E Light will evaluate the potential amount of exposure on each project within an affected area and develop a specific policy for the project.

• All projects in a potentially exposed area will stock respirators and will make available to any employee a respirator upon request provided the employee agrees to the voluntary respirator program

EXTREME POTENTIAL EXPOSURE AREAS

• EPE Areas will be designated by the Director of Education and Loss Prevention based on declared high exposure by local authorities in combination with documented and confirmed serious cases in the area

• In areas determined to be extreme exposure potential areas E Light will require the following all employees to be fit tested for respirators, remain clean shaven at work, and will implement a respirator program.
