Long COVID

A disease produces specific signs or symptoms; symptoms are reported by patients and largely subjective, and signs are elicited by physicians and have a more objective quality. A syndrome is a set of symptoms suggesting the presence of an underlying disease or condition. COVID is a disease, long COVID remains, an often ill-defined syndrome.
Active immunity means your body’s immune system gets revved up and primed by previous infection or exposure to vaccine antigens, whether it’s the real thing, i.e., getting sick with COVID, or via exposure to a human-made varietal from a vaccine (mRNA or conventional). Yet, somehow there’s this hue and cry that getting the real thing just isn’t as good as getting jabbed. Is it true? 
Daily infections and deaths have been the main coronavirus public health concerns. Little attention has been given to the grab bag of lingering symptoms collectively known as “long-haul” or “post-COVID-19 syndrome,”  affecting about 15% of the U.S. population. Here we use public data from two ongoing research projects to summarize the current state of knowledge.
We're learning more every day about the SARS-CoV-2 virus, but it will likely present surprises. The best strategy is still to prevent new infections.
Perhaps. A new study in Science suggests a very high prevalence of the Epstein-Barr virus in patients with Multiple Sclerosis (MS). This strong evidence may aid those suffering from MS and give us all a better sense of how endemic infections may have long-term consequences that we are slow to recognize because of the long delay between infection and symptoms.
Most COVID-19 concerns have focused on daily infections and their accumulated impacts. Relatively little attention has been given to the lingering symptoms known as “long-haul COVID,” even though it comprises some 30% of cases. The available data are spotty but amenable to the same kinds of population analysis that has been applied to daily cases.
The strange neurological symptoms of "long-COVID" may have an explanation: another virus. A study has examined whether COVID promotes the reactivation of the Epstein-Barr Virus, an ubiquitous herpes virus that causes mono in teens. The evidence suggests that this is, indeed, the case, and it's EBV that's causing some of the long-COVID symptoms.
The pandemic is not a monolithic event; it is a dance of the virus and our behavior. What we have learned about pandemics from the mistakes in our models. What about “long” COVID? Why does “if it bleeds, it leads” make sense?
