WHO has published Human infection with avian influenza A(H7N9) virus – update. Excerpt:
On 12 February 2014, The Ministry of Health (MOH) Malaysia reported a human case of avian influenza A(H7N9) virus.
Details of the case are as follows:
A 67 year old woman tourist from Guangdong Province, China, arrived in Malaysia on 3 February in a tour group of 17 persons, including relatives, and stayed overnight in Kuala Lumpur, Malaysia. The tour group then went on a visit to Sabah, Malaysia from 4 to 6 February. On 7 February, she was admitted to hospital and later transferred to another hospital in Sabah. The patient is currently in a stable condition.
Four days prior to travelling to Malaysia, on 30 January 2014, she was treated in China for symptoms of fever, cough, flu, fatigue and joint pain. Given the onset of symptoms, and travel dates, the most likely exposure occurred before arrival in Malaysia.
The Malaysia Ministry of Health is conducting an investigation including contact tracing and is also coordinating information sharing with the Chinese Government.
Sporadic human cases
While the recent report of avian influenza A(H7N9) virus detection in live poultry exported from mainland China to Hong Kong SAR shows the potential for the virus to spread through movement of live poultry, at this time there is no indication that international spread of avian influenza A(H7N9) has occurred. However as the virus infection does not cause signs of disease in poultry, continued surveillance is needed.
Should human cases from affected areas travel internationally, their infection may be detected in another country during or after arrival. If this were to occur, community level spread is unlikely as the virus does not have the ability to transmit easily among humans. Until the virus adapts itself for efficient human-to-human transmission, the risk of ongoing international spread of H7N9 virus by travellers is low. The overall risk assessment has not changed.
