Advice to returned travellers from
countries affected by swine influenza
Symptoms of swine influenza are similar to those of seasonal influenza, usually a feverish illness
accompanied by one or more or more of cough, sore throat, headache and muscle aches. For most people
this illness appears to be mild. Infection with this virus is treatable with the anti-viral drugs oseltamivir
(Tamiflu®) and zamanivir (Relenza®).
What should I do if I have returned from a country affected by swine influenza?

identified, it is important for you to monitor your health closely for seven days after your visit to the
affected area. There is no need for you to isolate yourself from other people as long as you remain well.
If during this period you develop a feverish illness accompanied by one or more of cough, sore throat,
headache and muscle aches, you should contact your GP by phone or seek advice from NHS Direct (0845

travel to an area affected. Depending on your symptoms you may be advised that further investigations may

your tests are back. Your household contacts should also monitor their health and follow the above advice
