Infographic Details

In the past 24-hours of reporting there has been one new case, reported from Fujian Province and no new fatalities. This brings the total for China to 127-cases including 24-deaths and Taiwan to 1-case without loss of life. Note that this includes asymptomatic cases.

To date 18.8% of all known cases have been fatal. For context the Case Fatality Rate of SARS was 10.9%.

There were no new announcements on discharges today. With no new data the current count of recoveries remains at 25 (19.5%) and asymptomatic cases at one (0.8%).

The most recent fatality reported by Chinese media was on the 29th April 2013 via Xinhua.

Recovery by Age Cohort

A lot has been made in recent weeks of the concentration of older victims of H7N9.

The average age of those who have died has been 65 but looking at it from a different angle, the average age of those who have recovered currently stands at 45.9.

Today’s additional chart looks at those patients who have been discharged from hospital and where we have their age data. It should be noted that I’ve included Meng, the two-year old from Shanghai as a boy even though his or her gender has not been confirmed.

Whereas 56.5% of the H7N9 deceased have been aged 65 or greater only 29.2% of those who recovered are in a similar age cohort. If you make a similar comparison of those aged 55 or above then its 73.9% fatalities against 45.8% recoveries.

To date, no one aged below 25 has died of the disease.
