February 5 in the afternoon, autonomous medical expert group is now working with medical experts in Nanning treatment plan. Currently, the patient is conscious, in stable condition.
The above translation from the February 4 and February 5 H7N9 bird flu updates from the Guangxi Department of Health identifies two confirmed H7N9 case (41F & 5M). The two cases create a pattern seen in earlier cluster in Guangdong and Hunan provinces, where the index case is hospitalized several days after disease onset (6 days for the above case, 41F), which is followed by a child (5M) from the identical location who is hospitalized 0-2 days after disease onset, with relatively mild conditions. This pattern yields cases that are reported within 1-2 days of each other, but with significant differences in disease onset dates (8 days for the above cluster) signaling human to human (H2H) transmission within the cluster.
The H2H transmission is further supported because this is an imported case. The index case developed symptoms while in Zhongshan City in Guangdong Province, but was diagnosed in Hengxian in Guangxi Province (see map). However, the child developed symptoms a week after the adult returned to Hengxian., signaling H2H transmission.
