It was a serious news even though it had long been suspected from the nature of COVID19 being systemic vasculitis. In a word, some parts of the patient are liable to cardiovascular diseases earlier in their lives possibly in severer manner.
The article in a recent issue of Nature; here.
The cohort was followed up for a year. They should be observed further before this finding is concluded as a sequel of COVID19.
The pathophysiological findings of brain fog has been reported in the same journal last fall. It was quoted here in this blog. It has been turned out to be endothelial apotheosis with the viral infection. It could be an expression of vasculitis in the brain.
The long term sequel of this viral infection should be focused on by the administrative authority and/or the government as well as the people themselves. It could be a burden not only for the patient but also for the society as demand for social security. A WHO related organization, European Observatory on Health Systems and Policies warns that; here.
From UK, a report on the incidence of long COVID in childhood/adolescence was reported; here. The follow up period is relatively short, that is, 3 months in this study. But the fact that more than 30% of the cases have been symptomatic and quite some portion of them have had neurological issues should be directed attention to since they are on the process of growth and may have issues in the future.
For a journal for ordinary people, Scientific Americans also published an article which announces to pay attention for the long COVID in the Omicron variant epidemic; here.
The Omicron variant has milder symptoms with relatively low mortality so far. The high peaking prevalence rate could jeopardize the medical care system as happens in some big city areas in Japan right now. In addition to the on going devastation in the medical care systems, this long COVID due to the pathophysiology of vasculitis should be carefully observed.
It is also noted vaccine is thought to alleviate long COVID if not perfectly. It is amazing some people still trust in the fake on vaccine, such as its ineffectiveness or even its harm to us. The long term safety of the vaccine is not completely established yet. It is almost an issue of rhetorical perspective such as events totally unknown to us yet. But they proved not to be harmful so far since it was introduced in clinical settings. Considering of the long sequel, vaccination should be given to everyone as soon as possible as scheduled.
