A 64-year old lady was evacuated from Indonesia and admitted to the National University Hospital (NUH) on the 14th of March 2006 for medical treatment. On arrival at NUH, she was assessed and noted to be febrile. She was diagnosed to have pneumonia and immediately isolated in the Intensive Care Unit (ICU).

In view of her condition and travel history from Semarang Indonesia where H5N1 influenza infections in poultry and humans have been reported, a H5N1 influenza PCR test was conducted as a precautionary measure. Although the initial test suggested a positive result, all four subsequent tests (including tests on additional specimens) have been negative.

Both the Ministry and the hospital have been vigilant in monitoring for patients with undifferentiated fever, pneumonia and relevant travel history. All suspect cases are immediately isolated away from other patients. Strict infection control measures are also in place. NUH staff who had contact with the Indonesian patient were wearing personal protective equipment, and all of them are well.

In this instance, the early detection of a possible suspect case testifies to the robust surveillance systems and protocols that are in place. The public can be assured that tight surveillance and strict infection control measures will continue in our hospitals. MOH has also developed a protocol for the referral of foreign patients to Singapore. Our hospitals have been informed.

Avian Influenza A (H5N1) is an infectious disease of birds. However, human cases have been reported and these cases were mainly infected through direct close contact with infected birds. There is currently no evidence of human-to-human transmission of the disease.

Travellers to areas affected by avian influenza are advised to avoid contact with live poultry. They are also advised not to consume raw or undercooked poultry (including eggs). In addition, travelers to these places are advised to practise good personal hygiene and seek medical attention early if they develop influenza-like symptoms.
