Two experts from the University of Queensland have issued a handy guide about how to minimise the risk of contracting coronavirus while out and about.
A New England Journal of Medicine study found that novel coronavirus is infectious in airborne droplets for about three hours.
Adjunct Associate Professor Ian Mackay and virologist Katherine Arden, both of UQ, wrote in The Conversation about what the study's findings meant regarding contraction, and how best to avoid it if possible.

But there were other tips for people who had to leave the house on essential tasks, such as grocery shopping, or healthcare.
1. It lasts longer on hard surfaces
On hard, shiny surfaces such as glass or metal (ie, a doorknob) the virus can remain infectious for 72 hours.
People are urged to avoid touching such surfaces in public if possible, or at least to wash their hands before touching their face, if they have to.
On cardboard and other porous surfaces, the virus lasted for 24 hours.
However, in both cases, the virus degrades quite rapidly.
2. Wash, wash, wash
In their Conversation piece, the experts said people should think of their hands as "the enemy".
As in accordance with health guidelines, people should wash their hands more regularly and for longer than usual.
Avoid touching your nose, mouth, eyes and to be safe, probably the rest of your face.
3. Going shopping
If hand sanitiser and wipes aren't on offer for customers, be sure to bring your own - but it doesn't matter what type of bag you use.
Paying by card is a lower-risk option, but the risk of transference is decreased furthest by paying online, if possible.
Canned food is safe - fresh food carries a potential risk.
But if you can cook, peel or rinse it, fresh food is more likely to be safe.
If you're getting your groceries delivered, avoid contact with the courier if possible - have them drop it outside your door.
4. Stay calm
Ultimately, you can't account for everything and you certainly can't live a touch-free life.
Be mindful, and aware of what is around you, and do everything you can to minimise the risk of contracting or transferring the virus.
