Farmers lung (not to be confused with silo-fillers disease) is a hypersensitivity pneumonitis induced by the inhalation of biologic dusts coming from hay dust or mold spores or any other agricultural products. It results in a type III hypersensitivity inflammatory response and can progress to become a chronic condition which is considered potentially dangerous. Signs and symptoms
Acute Stage: Appears four to eight hours after exposure. Symptoms such as headache, irritating cough, and shortness of breath upon physical exertion. Subacute Stage: Symptoms persist without further exposure, and increase in severity. Symptoms include: shortness of breath upon exertion, chronic coughing, physical weakness, occasional fever and sweating, decrease in appetite, aches and pains. Chronic Stage: Debilitating effects are now considered long-term. Symptoms include: severe shortness of breath, chronic coughing, physical weakness, occasional fever and sweating at night, decrease in appetite, and general aches and pains.These symptoms develop between four and eight hours after exposure to the antigens. In acute attacks, the symptoms mimic pneumonia or flu. In chronic attacks, there is a possibility of the victim going into shock and dying from the attack. Causes
Permanent lung damage can arise due to ones inability to recognize the cause of symptoms. Farmers lung occurs because repeated exposure to antigens, found in the mold spores of hay, crops, and animal feed, triggers an allergic reaction within the farmers immune system.
The addition of clindamycin or gentamicin reduces toxin production and mortality. In some cases doctors will prescribe other treatments such as blood pressure medications (to stabilize blood pressure if it is too low), dialysis, oxygen mask (to stabilize oxygen levels), and sometimes a ventilator. These will sometimes be used to help treat side affects of contracting TSS. Prognosis
With proper treatment, people usually recover in two to three weeks. The condition can, however, be fatal within hours. TSS has a mortality rate of 30%–70%. Children who are affected by TSS tend to recover easier than adults do. Complications
Amputation of fingers, toes, and sometimes limbs 
Death
Liver or Kidney failure 
Heart problems 
Respiratory distress 
Septic shock 
Other abnormalities may occur depending on the case

Prevention
During menstruation:
Use pads at night instead of tampons
Try to keep up with changing a tampon every 4 to 8 hours
Use low absorbent tampons
Follow directions when using vaginal contraceptives (sponges or diaphragms)
Make sure to maintain good hygiene during a menstrual cycleFor anyone:
Keep open wounds clean
Watch wounds and cuts for signs of infection (e.g. pus, redness, and warm to touch)
Keep personal items personal (e.g.towels, sheets, razors)
Wash clothing and bedding in hot water

Epidemiology
Staphylococcal toxic shock syndrome is rare and the number of reported cases has declined significantly since the 1980s.
