The patient had not left Langfang City between June 30 and July 9, so presumably she contracted H7N9 locally. Her onset seems to have been July 10, when she took her own temperature (38ºC=100.4ºF). Three days later she went to the community hospital in Langfang and was treated as an outpatient. But next day, July 14, she was running a 40ºC temperature (104ºF) and went into the China Petroleum Pipeline Bureau Langfang General Hospital, where X-rays showed pneumonia in her left lung. A course of antibiotics predictably had no effect.
On the afternoon of July 18 she was referred to Chaoyang Hospital in Beijing, where her symptoms worsened and she was placed on a ventilator. On the 19th she tested positive for H7N9 and was move to intensive care.
On the morning of July 20 the Beijing Municipal Health Bureau convened several experts who diagnosed her with "viral pneumonia, acute respiratory distress syndrome, severe sepsis, acute kidney injury, disseminated intravascular coagulation."
Meanwhile, the patient's 9 family members have been tested and isolated, with none so far showing a temperature or symptoms.
She is now in a single room with negative pressure and staff are using gowns, masks and goggles. She is being given antiviral drugs and ECMO.
And here's an English-language report from China Daily that confirms many of the details and adds a few more—notably a comment from a flu specialist who's perplexed at a flu case turning up in a sweltering north-China July.
