![]() Travel Health Advisory Avian Influenza A (H5N1): Human Activity in Asia and Europe Updated:
January 18, 2006
The Public Health Agency of Canada continues to closely monitor occurrences of avian influenza A (H5N1), or “bird flu”, in birds and in humans in Asia and Europe, with particular attention to the current outbreak in humans in Turkey. Situation Update: Turkey The World Health Organization and the Turkish Ministry of Health are currently reporting 21 laboratory confirmed human cases of A (H5N1), including four deaths.Evidence to date suggests that no sustained human-to-human transmission has occurred and that close contact with infected birds remains the principal source of infection. At this time, outbreaks of avian influenza A (H5N1), in poultry, have been confirmed in 12 of the country's 81 provinces. An additional 19 provinces experiencing outbreak activity are under investigation. Avian Influenza in Birds Since mid-December 2003, several Asian countries have reported avian influenza A (H5N1) activity in poultry and wild birds. In July of 2005, the disease, which had previously been confined to Asia, was confirmed in birds in an increasing number of European countries. According to the World Organization for Animal Health and based on criteria established in the Terrestrial Animal Health Code (2005), A (H5N1) large outbreaks among birds continue to persist in: Cambodia, China, Indonesia, Thailand, Vietnam, Russia, Kazakhstan, and Mongolia. More recently, the virus has been confirmed, in birds, in the previously unaffected countries of Turkey, Romania, Croatia, and Ukraine. For additional information about H5N1 and other avian influenza outbreaks among animals, visit the World Organization for Animal Health Web site. Source: World Health Organization, World Organization for Animal Health, EU - Europa Information on Avian Influenza A (H5N1) Avian influenza A (H5N1) is a contagious viral infection that is thought to affect all species of birds; although rare, infection in humans can occur. The first documented infection of humans with the avian influenza A (H5N1) virus occurred in Hong Kong in 1997, when the strain caused severe respiratory disease in 18 humans, six of whom died. The infection in humans coincided with an epidemic of H5N1 in Hong Kong's domestic poultry population. Investigation into human cases of H5N1 suggests that direct contact with infected poultry has been the primary, if not exclusive, means of infection; although, in a small number of instances a link to direct contact with infected poultry was not identifiable. In a few cases, it would appear that human-to-human transmission may have occurred. However, such cases involved extended close personal contact with an infected individual (i.e. providing bedside care for an infected relative) and no further transmission occurred. Several anti-viral drugs are available for the prevention and treatment of seasonal influenza in Canada. Although, none of the anti-viral drugs have been shown to prevent A (H5N1), studies done through the WHO Global Influenza Surveillance Network have shown that the anti-viral Oseltamivir may be effective in the treatment of A (H5N1). Recommendations As a precautionary measure, the Public Health Agency of Canada recommends that it would be prudent that travellers to Cambodia, China, Indonesia, Thailand, Vietnam, Russia, Kazakhstan, Mongolia, Turkey, Romania, Croatia, and Ukraine - where avian influenza A (H5N1) outbreaks in fowl are confirmed, consider the following measures:
Canadian Food Inspection Agency recommendations to prevent the introduction of avian flu into Canada's animal population:
As a reminder… The Public Health Agency of Canada routinely recommends that Canadian international travellers seek the advice of their personal physician or travel clinic prior to international travel, regardless of destination, for an individual risk assessment to determine their individual health risks and their need for vaccination, preventative medication, and personal protective measures.
The Public Health Agency of Canada recommends, as well, that travellers who become sick or feel unwell on their return to Canada should seek a medical assessment with their personal physician. Travellers should inform their physician, without being asked, that they have been travelling or living outside of Canada, and where they have been.
