The first thing you need to know when it comes to avoiding catching the novel coronavirus is how to wash your hands properly. Here are the official Great British National Health Service guidelines for children:
and for grown ups:
Personal protective equipment (PPE for short) is also essential. Whilst there is much fake “debate” about the pros and cons of face masks on the internet, The Lancet is in no doubt:
Mass masking is underpinned by basic public health principles that might not have been adequately appreciated by authorities or the public.

Here’s a handy overview of why a Ninja style mask over one’s nose and mouth is much, much better than nothing at all:
