World - Influenza A (H1N1)
28 April 2009 - Several countries have confirmed cases of influenza A(H1N1). General information on the influenza A(H1N1) have been posted on the WHO website.
WHO does not recommend restricting international travel. As usual it is considered prudent for people who are ill to delay international travel and for people developing symptoms following international travel to seek medical attention.
Regarding the risk of being infected by an influenza virus, travellers are advised, whenever possible, to avoid crowded enclosed spaces and close contact with people suffering from acute respiratory infections. Hand-washing after direct contact with ill persons or their environment may reduce the risk of illness. Ill persons should be encouraged to practice cough etiquette (maintain distance, cover coughs and sneezes with disposable tissues or clothing, wash hands).
Regarding specific measures related to protection against influenza A(H1N1), information is presently insufficient to make recommendation on the use of antivirals. For the use of antivirals in treatment of influenza A(H1N1) virus infection, the clinicians have to make decisions based on the clinical and epidemiological assessment and harms and benefit of the treatment for the patient.
