As a teacher, we were given the following advice about what to do when we get home on days we go into school, especially if we live with anyone who may be vulnerable:
-Have a black binliner waiting by our door.
-Undress as soon as we come in and put all clothes into the binliner.
-Have our washing machine waiting and open.
-Put our clothes in the washing machine without touching it.
-Try to avoid touching surfaces.
-Have a shower, and wash ourselves thoroughly.
-Then close the washing machine door and put the wash on.
Initially, this sounds like overkill, but if you think it through, it's a relatively effective way to make sure you're minimising any transfer of the virus inside your home, if it just on your clothes etc.
