Scurvy, once common among convicts who went without fresh fruit and vegetables on long sea voyages, is now so rare in Australia that serious cases are almost always found and treated.

Doctors were left 'baffled' after it was found a six-year-old boy suffered a heart attack and died from scurvy - a disease that has barely been seen since the 19th century

Queensland coroner said publicising the boy's death might help prevent similar tragedies.
