Scientists have identified persistent damage in the lungs of COVID-19 patients at least three months after they were discharged from hospital, and for some patients even longer. Once deemed virus-free and ready to be sent home, the often-long road to recovery – including rebuilding lung capacity and overall respiratory health – begins. A 50% increase in lung X-ray findings within 24 to 48 hours was considered an early warning indicator of impending conversion to critical disease. In our model, this is quickly brought under control by T cells, another type of immune cell which is dispatched for this very purpose. A Thick Sludge.
