To help stop the spread of viruses
like the flu or coronavirus
good hygiene is essential.
That starts with washing your hands thoroughly
with soap and water
whenever you cough, sneeze or blow your nose,
prepare food or eat, care for someone sick,
touch your face, or use the toilet.
Remember to cough or sneeze into your arm
or a tissue. Bin the tissue and wash your hands.
Together, we can help stop the spread
and stay healthy.

Everyone must also stay 1.5 metres away from other people whenever possible.
This is called physical distancing.

Answer passage (source: Australia):
page_title: COVID-19 Mythbusting
section_headers: If you can hold your breath for 10 seconds, you’re ok
section_content: Holding your breath for 10 seconds without coughing does not indicate you are
free from coronavirus. If someone has an acute viral infection, it may be
difficult for them to take a deep breath. However, being able to breathe
deeply doesn’t mean someone is free of COVID-19. People’s symptoms vary and
the only way to determine if you have the virus or not is to get tested.

THis directly answers this question by saying that holding your breath is not a good way to indicate if you are sick.

Answer passage (source: Australia):
page_title: COVID-19 Mythbusting
section_headers: Breathing techniques can cure the virus
section_content: This breathing technique does not cure the virus. Controlled coughing helps
with conditions such as cystic fibrosis to clear airways of mucus. It is
relatively safe to perform as the mucus in cystic fibrosis usually can’t
infect others. In the case of COVID-19, where people can infect others through
airborne droplets, the opposite is true and this technique could help spread
the infection. Learn more about the ABC's investigation into this
myth.

Reviewer feedback on this answer:
This answer does not relate to if you are able to tell if you are sick, only to attempt to cure yourself, thus not answering the question.
This doesn't answer the question and talks about how to control the virus through coughing techniques not on diagnosis.
