It is possible that once efficient human-to-human transmission of H5N1 occurs certain countries may close their borders sporadically believing (rightly or wrongly) that this measure would be effective in reducing the spread of influenza. Screening (with quarantine measures) could be established at borders. If justified by risk/benefit analysis it may be advisable to request employees to consider postponing non-essential travel outside Canada when the pandemic starts. Arrangements may also be required for employees who are stranded outside of the country because borders are closed. In addition, it may be advisable to develop an impact analysis model taking.
