PPE recommendations are a bit confusing.

WHO currently says that healthcare professionals in non-AGP areas who aren't doing AGP should wear surgical mask, gloves, apron, and do a risk assessment for eye protection. All of that PPE is single use. This is the current practice in English NHS settings. See here: https://twitter.com/OutbreakJake/status/1242020875328684038

If aerosol generating procedures are happening the healthcare professional needs a fit-tested FFP3, gown, gloves, and eye protection. https://twitter.com/OutbreakJake/status/1242233685392396289?...

Surgical masks are fluid resistant, and this is an important part of their protective property. Home made cotton masks tend not to be fluid resistant.

If you are in contact with infections substances all day every day you need 99.99999% (I'm pulling this figure outta my ass, but you get the picture) protection. To bring R0 below 1 you need 75% protection. That's why we saw advice like "just wash your hands" - ultimately inadequate, but it wasn't apriori silly.
