Documentary Enrichment: · General information

Essentials

Endemic mycosis of Southeast Asia affecting mainly people whose immunity is greatly diminished.

Agent
Talaromyces marneffei
Transmission or exposure
Environment · Respiratory tract

Situation and vulnerability

Advanced HIV, transplantation or other immune deficiencies increase the risk. South-East Asia, southern China and north-eastern India are contexts to be clarified.

Signs and limits of their interpretation

Small papules sometimes painless, fever, weight loss, cough or diarrhea are possible. Forms can reach blood and several organs.

Diagnosis and monitoring

Samples adapted to the affected site are examined in the laboratory by culture, microscopy or other methods. An isolated skin injury does not confirm this infection.

Prevention and care

The disease requires prescribed antifungal drugs. Drug prevention may be considered in some high-risk people; it is not decided on the destination alone.

Practical issues

Do the bamboo rats transmit the disease directly to humans?

The CDC indicated that there was no evidence to establish this transmission. Inhalation from the environment is considered as a route of acquisition; the disease is not transmitted between people.

Preparing for an exchange with a professional

  • Residences and trips in Asia, whether or not old
  • Immune status and treatments
  • Start of lesions, fever and weight loss

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.
