I know during C19 BA increased their cleaning procedures of aircraft etc. Does anyone know if these are still in place?

Certainly this throughout this year I’ve noticed myself coming down with cold/flu symptoms more frequently almost after always travelling on a BA plane - obviously not helped by packed cabins of pax sneezing and spluttering everywhere as well as there being airports where only cold water is dispensed from toilet taps. It could of course all be coincidence.

Just wondering if there is anything that can be done to mitigate this/if BA still have strong(er) cleaning procedures.
