The myth that coronavirus only severely affects older people has shattered as examples of young people succumbing to the disease pour in from around the world. 

A 12-year-old girl in the US is fighting for her life on a ventilator just a day after testing positive for COVID-19; an 18-year-old has been the youngest life claimed in the UK; and a premature baby in Israel is in a serious condition after catching the virus. 

In fact, in Australia, patients under the age of 54 make up more than 40% of all coronavirus hospitalisations.
