Previous reports of person to person transmissions have all occurred in family clusters, suggesting that either common exposures or genetic susceptibility might contribute to the infection.
The study describes two patients who shared the same ward in a district hospital in Zhejiang Province, China in February 2015.
The first (index) case was a 49 year old man who became ill after buying two chickens from a live poultry market for the wedding ceremony of his elder daughter. He developed a fever, cough, and sore throat and was admitted to a district hospital on 18 February.
He was diagnosed with H7N9 virus on 24 February and was admitted to a specialist hospital ward with intensive care facilities. He died of multi-organ failure on 20 April.
The second case, a 57 year old man with a history of chronic lung disease (COPD), developed flu-like symptoms after staying on the same ward of the district hospital as the index case for five days (18 to 23 February).
He was diagnosed with H7N9 virus on 25 February and died of respiratory failure on 2 March.
A total of 38 close contacts of both cases, including family members and health workers, were tested for the virus.
Two samples taken from the chickens purchased by the index patient as well as five of 11 samples from the live poultry market he visited were positive for H7N9 virus.
The second patient had no history of poultry exposure for 15 days prior to his illness. Samples from his home, from chickens raised by his neighbours, and a local chicken farm were all negative for H7N9 virus.
Yet the genetic sequence of H7N9 virus from the second patient was nearly identical to that from the index patient, and genetically similar to the virus samples taken from the live poultry market visited by the index patient.
