A study at Duke University recently discovered a possibly deadly fungus afflicting humans and animals in British Columbia and the northwestern United States. The fungus, which was previously a risk only to AIDS and transplant patients, or to those with immune disorders, has mutated into a new strain that is now believed to affect healthy subjects as well.
According to the National Institute of Health, the airborne Cryptococcus gattii is likely to spread to surrounding areas. Researchers calculated its mortality rate at approximately 25 percent based on 21 cases in the U.S.
"Between 2003 and 2006, the outbreak expanded into neighboring mainland British Columbia and then into Washington and Oregon from 2005 to 2009," said Edmond Byrnes of Duke University. "Based on this historical trajectory of expansion, the outbreak may continue to expand into the neighboring region of Northern California, and possibly further."
Infection from the fungus can occur upon inhalation, according to National Geographic News. A vaccine or other form of prevention for the new strain has yet to be developed, however, antifungals can treat infections.
Onset of symptoms can appear two weeks or longer after infection and can include chest pain, headache, shortness or breath, weight loss and fever.
