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.
