Blastomycosis (cont.)

What Is the Prognosis for Blastomycosis?

The prognoses (outcomes) for blastomycosis is variable; about 50% of infections do not even produce symptoms. Those patients diagnosed and treated appropriately usually have a good outcome although they need to take medications for many months. Immunosuppressed patients with blastomycosis have outcomes that range from good to poor. Although some may recover completely, the mortality rate (death rate) is about 29%. It can be as high as 40% with patients with AIDS, and 68% with ARDS.

How Can I Prevent Blastomycosis?

Prevention of blastomycosis is difficult because the fungi are widespread in the U.S. and many other countries. The CDC recommends that immunocompromised people avoid going into thickly wooded areas where the fungi occur in high numbers. Currently, there are no vaccines available to protect individuals from the fungi that cause blastomycosis, but researchers are trying to develop a vaccine.
