What distinguishes diseaseBacterial zoonose most often transmitted by small mammalian fleas; the lung form can be transmitted by droplets.Zoonosis acquired mainly by inhalation of contaminated dust from infected farm animals.Respiratory Zoonosis associated with inhalation of dust from secretions or fients of infected birds.
PreventionAvoid dead or sick animals in the affected areas and immediately monitor health measures in case of alert.Health care of low-income people, safe management of animal waste and respiratory protection in exhibiting activities.Cage hygiene, ventilation, dust reduction and protection of exposed professionals.

Diagnosis and monitoringThe clinical picture and exposure guide an urgent assessment. Confirmation and care are organized by the medical services; do not wait for all signs.Blood tests are looking for infection. The results can take time; the professional may decide to treat a suspicion before they return.Blood or respiratory samples may be requested. Tests are not available everywhere; the history of contact with birds helps guide research.
Preparing for an exchange with a professional
  • Place and dates of exhibition
  • Puces, rodents or sick animals
  • Lowering and proximity of herds
  • Pregnancy and history of heart or vascular disease
  • Species and Origin of Birds
  • Cleaning cages or poultry work

What this table allows to understand

The selected records cover 1 agent family/families. They share the following routes or contexts in our catalogue: Animal / zoonosis · Respiratory. These associations describe the selected data; they do not measure contagiousness, severity or personal risk.

To review a comparison, choose one row and open the reference for each column. A preventive measure mentioned in one record and absent from another is not necessarily unnecessary in the second situation: the summaries and their scope may differ.

If symptoms occurThe table does not select any test or treatment. A fever after a stay in the malaria area should be reported promptly, even if prevention has been taken.
