@Dave R; many health workers such as those in NSW currently caring for the 61 Greater Sydneysiders in either ICU or on ventilators are deeply scarred by their experiences - some even suffering a PTSD.
During Victoria's second wave of Covid19 even those casual and under-trained staff working in Morrison's disgusting, neglectful aged care facilities had to be furloughed as Covid19 delivered horrible deaths to residents they did their best to care for.
Even if the pandemic ended tomorrow we'd have many people scarred and / or immuno-compromised because of their experience of Covid19.
