My mother qualified as a nurse in 1949 in she went on to a life in public health until she retired in 1994.
She has been through a few epi/pandemics, on the front line.
I was chatting to her on Tuesday for her 89th birthday, she said keep a distance, and wash your hands and forearms properly with soap often.
Growing up as kids during every cold or flu season we were told the same, we seldom had any sickness at home.
Her only other medical advice has always been don't take antibiotics if they are prescribed unless you really think that you really need them as each dose waters down the the next. One day your life may count on them.
