I would be willing to bet that, even now, some significant percentage of people who are known to have had the disease would tell you that it was not a case that they experienced nothing at all. Ie, they didn't even know they had it.Yes, there are unusual facets like the rare neurological effects described which probably result from a deranged immune response to SARS2. Yes, there are unique factors to consider like whether antibody dependent enhancement is part of severe illness and may be an ongoing and increasing issue with future infection or with vaccination (ie second exposure to antigenically drifted coronavirus months or years later results in deranged immune response and worse disease). We don’t really know, and we don’t know what the future holds. However, RIGHT NOW, these complications are very rare and should be talked about as such until evidence warrants otherwise.
Anecdotally, the few people I know who've had it, have all reported symptoms, and usually significant symptoms that are temporary. But also usually more than nothing, long term.
I don't think it is unreasonable to suspect that something might happen with these people long term. I sure do hope not. I certainly hope not debilitating. That of course depends on how you define that. Is chronic pain, that makes you take meds every day to function normally, debilitating? Just throwing wild things out, with no proof. There of course can be no proof. We won't know, until later.
