Essentials

Mycosis acquired by inhalation of environmental spores, most often affecting the lungs.

Agent
Blastomyces spp.
Transmission or exposure
Environment · Respiratory tract

Situation and vulnerability

Some of the infections remain silent. Immunodepression increases the risk of serious forms and spread to other organs.

Signs and limits of their interpretation

Fever, cough, shortness of breath, night sweats and weight loss are possible. Humps, blisters or skin ulcers may also occur.

Diagnosis and monitoring

The balance sheet can use blood, urine or tissue tests and lung imaging. Travel and lack of improvement under antibiotics can guide research.

Prevention and care

A stay in an area where the fungus lives and persistent pneumonia are useful information to report. A precise assessment guides the tests and antifungal management.

Practical issues

Do the symptoms always appear immediately after exposure?

No: The CDCs describe a typical delay of several weeks to a few months. It is useful to mention previous activities and trips, not just those of the last days.

Preparing for an exchange with a professional

  • Travel and activities in the last three months
  • Skin injury and respiratory disorders
  • Immunodepression and response to treatments

Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.

Individual decisionThe choice of a test, treatment or prevention depends on the local situation and recommendations. In case of distress, call 911.
