Statistics of individuals with valley fever and related misdiagnosis to make the public aware
- Each year, more than 20,000 valley fever cases are reported in the United States, but researchers estimate the fungus is infecting more than 150,000 people. Many people go undiagnosed because they don't seek to find the cause of their illness.
- Everyone is at risk of breathing in the fungus, but people of African American or Asian decent, pregnant women in their third trimesters and people with weakened immune systems are at highest risk of developing the illness.
- Valley fever is not contagious.
