There is no proven treatment at this early stage but we will doubtless have more information about this soon. It can be assumed that non-pharmacologic approaches are effective such as fluid support, oxygen and ventilatory support. Most recently the national data suggests that 17.7%, 10.4% and 7.0% of all cases have disease requiring respiratory support in Wuhan, Hubei (not including Wuhan) and the rest of China (respectively). About a quarter of all require ventilation while 75% require oxygen support only. The variation in severity rates probably reflects the outcomes in an overwhelmed health system. Extra Corporeal Membrane Oxygenation (ECMO) is potentially of benefit and we will know more particularly when cities with higher technology health systems become affected and ECMO is truly tested in the most severely ill. ECMO is currently being used in China, however, its effectiveness is yet to be determined.
