Looking for WET v3.1?

As of September 23, 2014, version 3.1 of the Web Experience Toolkit is no longer supported. The source code and documentation have been moved to the wet-boew-legacy repository.

The Text highlighting component highlights any text within a pre-defined area that matches case-insensitive search criteria specified through the URL's query string. Supports multi-word strings, including spaces and basic punctuation.

Note: Search criteria using special regex characters such as ", |, ?, +, ( or ) may be partially or fully excluded from the results.

How Do I Use It?

  1. Define your search area. Add the wb-txthl class to the tag whose contents you want to search in.
  2. Specify the search criteria in a URL query string. Add txthl=<text_1>+<text_2>+<text_3> to the query string.
    Note: HTML markup validation requires all spaces in links to be replaced by %20.

Avian Influenza (H5N1) Worldwide

Updated: March 17, 2010

Travel Health Notice

Travellers are reminded that countries around the world continue to report cases of avian influenza (H5N1), or "bird flu".

While avian influenza (H5N1) commonly causes sickness in birds, it can also infect people. People who contract avian influenza can get very ill, and more than half die from it.

If you are travelling to a region where avian influenza (H5N1) is known to be present, the Public Health Agency of Canada (PHAC) recommends that you:

  1. Avoid all high-risk such as poultry farms and live animal markets.
  2. Avoid eating undercooked eggs or poultry.
  3. Wash your hands frequently.
  4. See a health care provider if you develop flu-like symptoms while travelling or after you return to Canada

About Avian Influenza (H5N1)

Avian influenza (H5N1), commonly known as "bird flu", is a viral infection that can spread easily and quickly among birds.

A particularly strong subtype called the Highly Pathogenic (H5N1) has been found in birds in parts of Asia, Europe, the Middle East and Africa. Humans have become infected with this virus.

Symptoms
  • Can take two to eight days and possibly longer to appear.
  • Usually include symptoms similar to human influenza such as fever, cough, aching muscles and sore throat.
  • In more severe cases people may develop serious respiratory conditions such as pneumonia which may lead to death. Fatality rates among hospitalized patients with confirmed infection is high (about 60%).
Transmission
  • Most human cases have been traced to direct contact with live infected birds or their droppings.

Where is Avian Influenza (H5N1) a Concern?

  • Asia, the Middle East, Europe and Africa have all had outbreaks of avian influenza (H5N1) in poultry since 2003.   
  • Since 2009, cases of humans having caught H5N1 have been reported from Cambodia, China, Egypt, Indonesia and Vietnam.
  • From 2003 to early 2010, there have been nearly 500 confirmed human cases in 15 countries.
  • Worldwide, almost 300 people have died from avian influenza (H5N1).

The World Health Organization (WHO) posts information on the total number of human cases of avian influenza and maps of where human cases of avian influenza have occurred.
