What is Histoplasmosis?

21:54 - 4 May , 2021

Disease

It is an infectious disease caused by inhaling spores of the fungus Histoplasma capsulatum found in the fecal matter of birds and bats, which affects the lungs and can invade other parts of the body.

Anyone can get it, especially those with a weakened immune system and exposure to the droppings of the aforementioned animals.

Histoplasmosis is not contagious, but it can occur repeatedly, with less intensity each time. The most vulnerable groups are:

  • People with a depressed immune system due to diseases or drug treatments.
  • Young children and elderly people.
  • Farmers.
  • Poultry farm workers.
  • Speleologist.
  • Gardeners.
  • People who control pests.
  • Construction workers.

Signs and symptoms Histoplasmosis

The symptoms will depend on the number of spores you have inhaled, so you may or may not have symptoms, which appear between 5 and 18 days after exposure to the fungus, the most frequent being:

  • Headache.
  • Joint and muscle pain.
  • Chills.
  • Tiredness.
  • High fever.
  • Chest pain.
  • Coughing fits.

Chronic histoplasmosis includes:

  • Weight loss.
  • Coughing up blood

Potential risks:

  • Lung damage.
  • Adrenal glands insufficiency.
  • Meningitis.
  • Problems in the pericardium, affecting the heart’s ability to pump blood.
  • Death.

Diagnosis and treatment Histoplasmosis

Once your doctor reviews your symptoms and medical history, they will perform a physical examination and order blood and urine tests, as well as samples of: 

  • Bone marrow.
  • Pulmonary secretions.
  • Lung tissue.

If your symptoms are mild and tests show no problems, you probably won’t need treatment. But if the infection has spread or you have chronic ailments, you’ll need antifungal medication for several months to a full year.

You can prevent histoplasmosis infection by avoiding exposure to closed, polluted environments such as henhouses, wearing a protective mask, and spraying water on the spot to counteract exposure to dust.
