It was the belief that disease was caused by 'bad air' that had a foul smell.
The theory outlined that if you were breathing in this poisonous gas you would get ill because the miasma carried disease.
Diseases were spread because the miasma was spread from person to person.
This was a popular theory for public health officials in the 19th Century as the most industrialised and overcrowded cities has the most foul smelling areas and the highest death rates.

When Louis Pasteur conducted a series of experiments in 1860s he realised that a specific microorganism was causing a disease in silkworms.
He then came to the conclusion that other microorganisms were causing disease in humans.
The theory only became fully accepted in 1880 and 1890 when Robert Koch and his team proved the microorganisms that were causing many of the killer diseased.
