Current Avian influenza (H5N1) affected areas
Recognition, reporting and testing of Severe Respiratory Illness
(SRI), including severe influenza-like illness (severe ILI), in current
avian influenza (H5N1) affected countries:
Health care Providers:
Continued vigilance is recommended for the surveillance, recognition, reporting and prompt investigation of patients with unexpected outcomes of severe influenza-like illness (severe ILI*) who are linked to H5N1 avian flu-affected areas (Table 1). For specific recommendations regarding screening, laboratory investigations and reporting, please consult your local or provincial/territorial health authorities.
_____________________
* Influenza-like illness (ILI) in the general population (FluWatch national case definition): Acute onset of respiratory illness with fever and cough and with one or more of the following - sore throat, arthralgia, myalgia, or prostration which could be due to influenza virus. In children under 5, gastrointestinal symptoms may also be present. In patients under 5 or 65 and older, fever may not be prominent.
Severe ILI may include complications such as: pneumonia, Acute Respiratory Distress Syndrome (ARDS), encephalitis and other severe and life threatening complications requiring hospitalization or resulting in death of otherwise healthy individuals.
Hospitals:
Enhanced SRI surveillance in hospitals is aimed at early detection of a re-emergence of SARS as well as other emerging respiratory infections, including novel influenza viruses of pandemic potential. Presently, enhanced surveillance is recommended for severe respiratory illness (including severe ILI) in persons linked to H5N1 avian flu-affected areas as well as SARS-affected areas.
Table 1, below, provides an up-to-date list of countries
experiencing human cases of H5N1 avian influenza. For detailed background
and recommendations on enhanced SRI surveillance in hospitals, please
consult your local or provincial/territorial health authorities. Also

Illness.
