Canadians who feel ill should defer their travel plans until they're better, federal health officials said Wednesday when releasing new swine flu guidelines.

The Public Health Agency of Canada released new infection-control recommendations related to travel on planes, trains, ferries and intercity buses.

Health Minister Leona Aglukkaq encouraged travel companies to allow Canadians to rebook easily if they fall ill.

The guidelines include advice on:

* How to deal with sick passengers and crew.
* Availability of handwashing for passengers.
* Regular cleaning of public areas in stations and vehicles.
