Having experienced the symptoms of the cronavirus infection twice , I realize that the virus has not been vaporized but it is being with us all the time . Those who advocate that the virus should have disappeared Must be mentally efficient .

The dominating symptoms I am having now are dizziness , fatigue and lower back pain . And I learned that the dizziness was not caused by Hypertension but virus ,although my blood pressure is high .

完全不要掉以轻心。必须严阵以待，随时加强抵抗力

妈呀 别瞎我

Our immune system will be enhanced or improved to a level high enough to maintain normal interaction with virus, as I believe.
How long is the time period required? Well, that depends. Each individual responds quite differently even to the same invasion of virus.
