As the COVID restrictions here in Australia slowly lift, it is with some trepidation that people, particularly older people, are emerging from their home sanctuaries.

The value of social distancing, hand washing and PPE has been pretty well established. But what of measures like the screening questionnaire for symptoms and the no-touch temperature check that is being done at practices, hospitals and even some retail shops? How greatly do these measures contribute to our safety?

Maybe not as much as we’d like to think if the experience of one little cruise ship (not the Ruby Princess) is anything to go by.
