Scarey!

A deadly, airborne new strain of fungus has emerged in Oregon. It has killed nearly one out of four known affected people so far and might also attack animals ranging from dogs to dolphins. And it is likely to spread, researchers now warn.

The new strain known as VGIIc of the fungus Cryptococcus gattii not only targets humans but has also proven capable of infecting dogs, cats, alpacas, sheep and elk. Other strains have even infected porpoises.

Although it can spread to mammals, it does not jump from animal to animal. Instead, people and other animals get it from inhaling spores released by samples of the fungus that infect trees.

Symptoms can appear two or more months after exposure. Most people never develop symptoms, but those infected may have a cough lasting weeks, sharp chest pain, shortness of breath, headache related to meningitis, fever, nighttime sweats and weight loss. In animals the symptoms are a runny nose, breathing problems, nervous system problems and raised bumps under the skin.

Treatment requires months to years of antifungal medications, and even surgery to remove the large masses of the fungus known as cryptococcomas that can develop in the body. So far it cannot be prevented, as there is no vaccine.
