None of these instances is proof that the current pandemic cases in those countries was sourced from those early cases, but it is fairly conclusive evidence that the virus was around months before the authorities knew of its existence.
It would be interesting to see historic analysis of sewage for Wuhan to determine how long it was before the Chinese first recognised that there was a new virus circulating. I suspect it was months. There may have been a subsequent Chinese cover-up, but given the virus was present in other countries months before it was identified as such, I think it is safe to assume that it also took the Chinese some time to realise what they were dealing with, by which time the virus had taken hold.
I did a 30-minute session on the bike trainer this morning without much hip flexor pain. Later, I limped around the block feeling very sore. Walking clearly causes more pain than cycling. During that limp, I filled a prescription for anti-inflammatories that was given to me by my GP prior to our aborted Continental Divide Trail hike. I'm not going to start taking them yet, because the discomfort is tolerable, but will take them when we start the cycling trip if I really need them.
I used many kinds anti-inflammatories during my running prime with mixed results. I have come to the view that inflammation is the body's way of repairing injuries and that anti-inflammatories may slow that healing process. I also know, from bitter experience, the pain-masking attributes of anti-inflammatories can entice you to cause more damage to the injured tissue. Better to feel the pain and know how you are going, unless it is intolerable and there are things that must be done.
