Pausters discovery had very little impact at first, because he was not a doctor and his work was initially for the brewing industry. In 1878, theories like the miasma theory were too embedded, and it took time for people to accept new ideas
surgery:
Joseph Lister was quick to apply the germ theory to surgery
The use of antiseptics led to fewer infections and therefore fewer deaths
cleaner conditions
The germ theory further proved the link between dirty conditions
It incentivised people to begin ensuring places were clean
vaccinations
Koch was the first scientist to identify a microbe that caused a specific disease
Once this had been done, vaccinations were developed that led to huge reductions in deaths
Investment in scientific medical research
science was responsible for the development of Pasters discovery
More governments and buisnesses became willing to fund research projects
Investment in public health provision:
Now that it was proven that disease was caused by germs in the air, people were more willing to spend money on public health provisions
This led to councils improving sewers, drains,fresh water supplies ect.
