|Location||Traditional bird roosts, poultry farms, enclosed buildings where birds or bats have roosted, and natural and organic fertilizers where spores are widespread|
|Description||Respiratory disease caught from breathing in spores spread by the wind|
|Cause||Bird droppings enrich the soil and promote fungus growth|
|Symptoms||A mild case may go unnoticed
A severe case may cause acute respiratory illness with flu-like symptoms or it could result in the dissemination of fungus through the blood stream
|Treatment||Seek medical attention from a physician|
|Prevention||Disperse large numbers of birds if they are living close to humans or livestock and posing a threat.
Test an area for Histoplasmosis before beginning work
Wear a self-contained breathing apparatus or face mask with a dust filter (less than two microns)
Wear protective clothing, boots, gloves and disinfect everything
Clear or bulldoze an old bird roost when the weather is wet or cold or dampen the area with water before beginning work
Decontaminate an old bird roost with a three–five percent solution of formaldehyde before clearing.
|Other Facts||Histoplasmosis fungus grows beneath bird roosts but it can’t form spores because of the acidic conditions in fresh droppings.
Spores can be released after droppings have dried out or been leached by the rain or if the soil is stirred up under dusty conditions.
