I had quite a disturbing email from my sister yesterday. In it she explained she can't speak as her throat is so sore. Her lungs are very painful and she can hardly walk without gasping for breath. She isn't sleeping well and is terribly worried that the virus has damaged her permanently. She first developed it about five weeks ago, and was discharged from the hospital two weeks ago, after having had ventilation and being on a drip.
She used to be so active and fit, but she fears her life has become a limited existence of tottering around in a feeble state.
I've heard that it can have long-term/permanent effects post-virally.
