When were the smallpox national epidemics
1722, 1723 and 1740-42
When was the worst smallpox epidemic and how many died
1796 where 3,548 people died
What was incolation
Giving someone the virus so they couldn’t get it again in the future by rubbing pus from scabs into a cut
Why did people use inoculation
They noticed if you survived a mild strain then you didn’t get it again in the future
Why was inoculation popular with doctors
They were able to become very rich from it for example a thomas Dimsdale was paid £10,000, became a baron and was awarded a salary of £500 a year from inoculating
What did Edward Jenner discover
Milk maids in his local area who had suffered from cowpox didn’t get smallpox
How did Jenner test his theory
He infected a boy named James Phipps and 25 other with cowpox and six weeks later with smallpox and Phipps and the other didn’t catch it.
What did Jenner do with his findings
Published them in his book “An Enquiry in the Causes and Effects of the Variola Vaccinae”
He named his work vaccinations after the Latin word for cow
What short term impacts did Jenners discovery have
100,000 lives were saved by 1800 and vaccines become compulsory
What long term impact did Jenner’s discovery have on medicine
19th century doctors creating new vaccines
WHO declared smallpox eridicated from around the world in 1979
Limitations on Jenner’s impact
-Vaccines were slow to become popular due to anti-Jenner propaganda.
-It wasn’t until 1840 vaccinations were made free and inoculation was banned
-Inoculators didn’t want to lose money
-Slow government response
-Royal Society refused to publish his work
How did institution help Jenners impact
-1840 vaccines were made free inoculations were banned
-1852 compulsory vaccination for children
-1871 enforced with fines for those refusing
How many monarchs were killed and what percentage of children were killed by smallpox
-5 reigning monarchs killed
-80% of children who got it
Methods used by people to try and stop Cholera in 1854
-Burning barrels of tar, cleaning houses and smoking cigars to ward off miasma
-Praying or wearing lucky charms for religion or superstition
-Burning victims clothes - 14th, 17th and 19th century
What period was this topic between
c.1700AD - c.1900AD
What did people believe caused cholera
Main belief was miasma however there were a lot of irrational and superstitious ideas aswelll
What were the four characteristics of cholera
-Diarrhoea and sickness that caused dehydration
-Usually fatal and people die between 2-6days
-The blood would become dehydrated and get thicker, rupturing blood vessel
-It was spread through person to person contact or water
Who was John Snow
-A surgeon and London’s leading anaesthetist
-Hegave Queen Victoria chloroform during the brith of Prince Leopold in 1851
What did John Snow notice about cholera
It couldn’t be spread by miasma as it didn’t affect the lungs, but the gut. Drinking water was contaminated by cholera-ridden faeces in the city’s drains, therefore cholera was transmitted by dirty drinking water.
Where did John Snow record his findings on cholera
“On the Mode of Communication of Cholera”
How did Snow prove cholera was spread by water
He created a spot map to show where deaths in his local area had taken place, in the area around Golden Square and Broad Street. It showed infection was most likely from the Broad Street water pump, so he removed the handle so locals couldn’t pump water and the cholera outbreak went away
Why was Snow’s impact limited
-Many people rejected his work and scientists said there were other deaths that lived further away from the pump
-Board of Health still believed in miasma and they argued there was no scientific proof and cleaning the water would have been expensive
-7 years before the germ theory and 30 before Koch isolated the bacterium causing the disease
Outline the Broad Street Investigation
-Snow interviewed people to find out where they get their water from in the Soho area door to door
-Found people who died mostly go to BSP
-Brewery in BroadStreet had no brewers due as they had drunk from a well in the brewery
-Local council permitted him to remove handle
-They found a liner in a cesspit was leaking into the ground and then to the water system
How did science and technology help Snow
He used the scientific method to investigate and record his findings, so he interviewed victims and families and used a dot map
