WHO is not recommending travel restrictions related to the outbreak of the influenza A(H1N1) virus. Today, global travel is commonplace and large numbers of people move around the world for business and leisure. Limiting travel and imposing travel restrictions would have very little effect on stopping the virus from spreading, but would be highly disruptive to the global community.

Influenza A(H1N1) has already been confirmed in many parts of the world. The global response now focuses on minimizing the impact of the virus through the rapid identification of cases, and providing patients with appropriate medical care, rather than on stopping its spread internationally.

Although identifying signs and symptoms of influenza in travelers can help track the path of the outbreak, it will not reduce the spread of influenza, as the virus can be transmitted from person to person before the onset of symptoms.

Scientific research based on mathematical modeling shows that restricting travel would be of limited or no benefit in stopping the spread of disease. Historical records of previous influenza pandemics, as well as experience with SARS, validate this.

People who are ill should delay travel plans. Returning travelers who become ill should contact their health care provider.

Travelers can protect themselves and others by following simple prevention practices that apply while traveling and in daily life.
