Probable person to person transmission of novel avian influenza A (H7N9) virus in Eastern China, 2013: epidemiological investigation.

ABSTRACT:

Objective

To determine whether the novel avian influenza H7N9 virus can transmit from person to person and its efficiency.

Design

Epidemiological investigations conducted after a family cluster of two patients with avian H7N9 in March 2013.

Setting

Wuxi, Eastern China.

Participants

Two patients, their close contacts, and relevant environments. Samples from the patients and environments were collected and tested by real time reverse transcriptase-polymerase chain reaction (rRT-PCR), viral culture, and haemagglutination inhibition assay. Any contacts who became ill had samples tested for avian H7N9 by rRT-PCR. Paired serum samples were obtained from contacts for serological testing by haemagglutination inhibition assays.
