Fact sheetVirus

Zoonotic avian influenza

Zoonotic avian influenza is a human infection with an influenza virus of animal origin. Exposure to infected animals or their environment is important in the assessment.

Documentary Enrichment: · General information

Essentials

Rare human infections associated with certain influenza viruses circulating in birds or other animals.

Agent
Avian influenza virus
Transmission or exposure
Animal/zoonosis · Close contact

Situation and vulnerability

Livestock farming, carcase handling or intervention in animal households may be exposed. The situation must be assessed with local health warnings.

Signs and limits of their interpretation

The disease may be mild or cause severe pneumonia. Inflammation of the eye may also be a manifestation of infection.

Diagnosis and monitoring

Animal exposure guides specific samples and tests. Signs similar to seasonal flu do not identify a zoonotic subtype.

Prevention and care

Avoid handling sick or dead animals and follow prescribed professional protections. Report conjunctivitis or respiratory signs after compatible exposure.

Practical issues

Does "highly pathogenic" indicate the severity in humans directly?

This classification describes the effects of the virus in poultry. It does not directly measure the severity of a human infection, which depends on several factors.

Preparing for an exchange with a professional

  • Species and nature of contact
  • Equipment and incident of exposure
  • Eye or respiratory symptoms and their dates

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.
