While I don't know if COVID causes long-term immunodeficiency- it does cause immune dysregulation & is associated with latent virus activation in the acute phase. It's been asssociated with higher risk of streptococcal tonsillitis for at least a yr in children in a large study 🧵
We also know that COVID co-infection with influenza and RSV is associated with an almost doubling in severe disease. There are numerous case reports of TB re-activation post-COVID, but the lack of systematic assessment makes causality hard to determine.
So, while I don't know whether COVID causes a level of immune suppression we need to be concerned about long term, the epidemiological evidence is concerning. And I wouldn't be make blanket statements that it doesn't increase infection risk, without evidence to support this.
@dgurdasani1 You don't need to make a blanket statement..... the government should have been using the precautionary principle since the beginning but we all know that went out the window 😬 #PrecautionaryPrinciple #WindsorOn 🇨🇦
