The exact nature of long COVID is still coming to light, but we just got some of the best evidence yet that this debilitating condition stems from a brain injury.
The droplet theory was dropped within the first few months. It turns out it’s not just COVID; many infections we thought were spread by droplets are actually airborne.
Surgical/cloth are pretty much useless for COVID. N95s buy you temporary protection unless you’ve got the special face fittings needed to actually seal your face. It depends on the environment you’re in but the worst case scenarios (like enclosed spaces without high airflow), the last study I saw was on the Delta variant and they said about 15 minutes if both parties are masked. It does get better from there though, with good ventilation you might have a few hours, and being outdoors you’re actually pretty safe.

Oh, thanks for the info. How effective are n95s and/or surgical/cloth masks given that information?
