VALLEY FEVER SPREADING IN PRISONS

COALINGA, Calif. — When any of the 5,300 inmates at Pleasant Valley State Prison begin coughing and running a fever, doctors do not think flu, bronchitis or even the common cold.

They think valley fever; and, more often than they would like, they are right.

In the past three years, more than 900 inmates at the prison have contracted the fever, a fungal infection that has been both widespread and lethal.

At least a dozen inmates here in Central California have died from the disease, which is on the rise in other Western states, including Arizona, where the health department declared an epidemic after more than 5,500 cases were reported in 2006, including 33 deaths.

Endemic to parts of the Southwest, valley fever has been reported in recent years in a widening belt from South Texas to Northern California. The disease has infected archaeologists digging at the Dinosaur National Monument in Utah and dogs that have inhaled the spores while sniffing for illegal drugs along the Mexican border.

In most cases, the infection starts in the lungs and is usually handled by the body without permanent damage. But serious complications can arise, including meningitis; and, at Pleasant Valley, the scope of the outbreak has left some inmates permanently disabled, confined to wheelchairs and interned in expensive long-term hospital stays.

About 80 prison employees have also contracted the fever, Pleasant Valley officials say, including a corrections officer who died of the disease in 2005.

What makes the disease all the more troubling is that its cause is literally underfoot: the spores that cause the infection reside in the region’s soil.

When that soil is disturbed, something that happens regularly where houses are being built, crops are being sown and a steady wind churns, those spores are inhaled.
