It literally says: "While most of the breakthrough cases were mild or asymptomatic, seven out of 36 workers tracked at six weeks (19 percent) still had persistent symptoms. These long Covid symptoms included a mix of prolonged loss of smell, persistent cough, fatigue, weakness, labored breathing or muscle pain."
It's certainly not great data, but it's still the best information we have as of right now.
I'm starting to think you've never encountered someone with a disability in your life.
Having muscle weakness in your arms mean that you can't do things like raising your hands to chest level and squeezing someone's hand. In practice it means you can't do everyday things like opening doors, or else can only do them with great difficulty.
Having muscle weakness in the legs means that if you're lying on your back, you don't have the ability to raise your legs off the ground. In practice, it means that you can't do everyday things like walking, or else can only do them with great difficulty and probably some form of assistance.
It's obviously not exactly the same as being paralyzed, but it's not that far off either. On the spectrum from "I'm not setting new deadlift PRs lately" to "I'm likely going to hospice soon", it's a lot closer to the latter than the former. There's a good chance that it means using a wheelchair, possibly indefinitely. I think you're doing people an extreme disservice by underplaying how serious this is.
With paralysis, the cause is usually traumatic spinal cord injury. Whereas with muscle weakness, the cause is usually something more like an autoimmune disease attacking the tissue around your spinal cord. But in both cases the end result is nerve signals not getting properly transmitted, and the impact on everyday life is pretty similar.
