As COVID-19 is a new disease we still do not know the long-term effects. There is active research into this area but the results will not be available for some time. We know from experience with other diseases that people with critical illness requiring a long term stay in intensive care can experience long term consequences, such as psychological effects including anxiety, depression and post traumatic stress disorder. There may also be long-term effects on organ function such as kidney and lung function; and muscle wasting and weakness. It is important to note, however, that not everyone requiring intensive care admission will experience these long term consequences.
