St Ninian’s High School Medicine and Health Through Time Section two - Public Health Electronic Textbook Tim Dargan BA(Hons) Dip (Law) ACIS QTS (Manx) Feb 2012 1 SECTION ONE: WHAT IS PUBLIC HEALTH? According to the Department of Health website www.dh.gov.uk/health/ category/policy-areas/public-health/ Public Health is: “ about helping people to stay healthy and avoid getting ill......” In our modern world this means our government takes an active role in helping people follow a healthy diet and exercise regime. In can also mean helping people stop smoking or give up drinking excessive amounts of alcohol. Our Government also ensures sewage and water systems are maintained by using taxation to pay for this infrastructure. The Government also has public health laws in place ensuring the population has clean drinking water and live in sanitary conditions. Harsh penalties exist for people who break these laws. This is the reflection of a healthy wealthy sophisticated civilisation. What we are going to look at in this study is how we got to the stage where we actually have an entire government department dedicated to keeping the population of the country healthy and productive. As civilisation developed what steps were taken to keep the populations of the villages that became towns and the towns that became and cities healthy? Who was responsible for these developments and how did they arrive at the decisions they made? What happened when they chose not to invest in Public Health? In order to do this we have to right back to the beginning........... 2 SECTION TWO: DID THE ANCIENTS HAVE PUBLIC HEALTH? As always when studying ancient civilisation we can only hypothesise as to how they actually lived their lives. In the excavated remains of Scara Brae in the Orkney Islands there is evidence suggesting Neolithic people had toilets and sewers taking waste away from their settlements. Bed Chamber Fire Pit Ensuite bathroom? Archaeologists have suggested that this room is a rudimentary “ Toilet” - there is evidence of sewage pipes leading away and down hill from this dwelling. We do not know this for sure but if we apply our modern ideas and thinking to the evidence we arrive at the conclusion that perhaps neolithic people had a basic idea of public health.......... 3 SECTION THREE ROMAN PUBLIC HEALTH Our first real evidence of a public system lies with the Roman Empire... One canʼt build an Empire if ones army is dying of disease. One canʼt recruit an Army if oneʼs citizens are dying of disease....... one has to have a plan - Dontcha know! We Romans donʼt do anything without a plan The Romans realised the survival and expansion of their Empire depended on the Health of their citizens and soldiers. (Originally before Rome had a professional Soldier all male citizens had to serve in the Army) Marcus Aurelius They also knew Laws had to be passed and harshly enforced to ensure all cities towns and villages throughout the Empire had the same standards of public Health..... When it came to people breaking their laws the Romans didnʼt mess about: The Romans knew they had to have the following: 1.A source of fresh clean water. 2.A means of storing this water 3.Public baths and toilets. 4.A means of taking sewage away from the population centre. This is what they did: 4 The Roman Public Health Model: Rivers are diverted to supply water to Aqueducts Aqueducts bring water to Resevoirs in and around cities Resevoirs supply water to public fountains, baths and drinking fountains Waste water is flushed away via a sewage system Waste water is flushed away via a sewage system 5 The Roman Public Health Model (Continued) The Romans had found a way to provide their cities with clean drinking water and to keep their citizens clean and healthy. Today we use a much more developed version of this system. The Romans have a problem: They can get their sewage away from their cities - but where do they put it? Answer: The sewage is flushed into local rivers down stream of their cities and towns. This is fine if you live in this town - not so good if you live down stream... Eventually the old enemy of Empire builders: Disease will make itʼs way to even the cleanest Roman town. (The Roman road system caused disease to spread quickly) The Roman have another problem: The River Tiber All Roads lead to Rome. As the Roman Empire comes under threat from Barbarian invaders once their armies on the borders are defeated the invaders move quickly to the gates of Rome. As the Empire is destroyed so is the infrastructure of water supply and waste disposal. As tax monies disappear the people employed to maintain these systems stop working - eventually the Roman Public health system fails. The Appian Way The Civilisations that replace the Romans have to begin again............ 6 SECTION FOUR: SAXON PUBLIC HEALTH: After the Roman Empire collapsed the Infrastructure the Roman brought with them Collapsed as well. Many roads fell into disrepair and were abandoned. Buildings were destroyed with their stone being used to build saxon homes and farm walls. The supply fresh water brought by Aqueducts began to fall away as these structures fell into disrepair. (There was no longer anyone who had the ability or were willing to repair and maintain these structures). As the country split into warring factions each vying for superiority people began to move from the countryside towards the well built and well defended old Roman cities. Cities such as York and London quickly become overpopulated with their rivers (that now supplied all the water these towns needed) became polluted. Diseases such as Cholera and Dysentry become commonplace. Cities did place regulations on where and how to dump Rubbish and treat sewage however these laws were poorly enforced. The universal standards the Romans maintained began to disappear. In order to maintain these high standards and the complex infrastructure the Romans charged heavy taxes and imposed heavy fines and punishments usually enforced by the fearsome Roman Army. In Saxon Britain there was no longer a large standing Army to enforce discipline and people were unwilling to pay high taxes. However there was one institution that still undertook large scale Engineering projects collected high taxes and followed the Roman systems of Public health : Public Health This way......... 7 SECTION FIVE: THE CHRISTIAN CHURCH As the Church grew in power and influence they were able to gain large amounts of land from the kings and Queens their missionaries were converting to Christianity. With this land the Church were also given the power to raise money through taxation or Tithe. Usually priests and Bishops were amongst the few educated people of power in any Kingdom they kept records. It is likely the Church had access to the original Roman writings detailing their Public Health systems. They used their taxation to build Churches and Monasteries. The Monasteries became the centre of many new towns. The church also used systems of public health similar to the Romans. They always had access to a fresh water Supply. They had large Cisterns to store the water They had separate bath houses and toilets. They had sewers to move waste away from the Monastery. Although the church together with their engineers and masons had the ability to extend their efficient public health systems to the towns that grew up around their monasteries - they rarely did. This in turn resulted in the spread of disease. 8 SECTION SIX: NORMAN PUBLIC HEALTH After 1066 the Normans began to colonise Britain. Saxon land owners and Nobles were stripped of their lands. Old wooden houses were destroyed to make way for Norman castles and stone buildings. By the 1060ʼs there were increasing numbers of Stone houses in towns. Two hundred years later many houses had at least stone foundations. The Normans passed laws to ensure Cess pits were built with a stone or brick lining and were emptied instead of being sealed off and left . As we have already seen Abbyʼs had stone sewage systems and plumbing to ensure clean water supplies. It took 600 years but slowly the Normans were beginning to return Britain to Roman standards of public Health. No matter how well the Norman cities were planned People at this time were still susceptable to Plague, Cholera, Small Pox and other diseases. It would not be until the discovery of Germ Theory that people understood how what disease was and how it spread. They were then able to put in place systems and measures to prevent disease. At this time plagues were often put down to “Gods Will” Rigid unquestioning belief in the guidance of the Christian church ensured people rarely looked for the causes of disease. This attitude also ensured Public health laws began to be ignored ..... 9 SECTION SEVEN: 14TH CENTURY PUBLIC HEALTH. By the 14th century cities and towns had become over populated . Cities were the places to trade and to make your fortune. Cities such as London were given their own Royal Charter - which meant they could govern themselves, pass their own laws and raise their own taxes. The problems: The City grew too fast. With the increasing population came disease and pollution. People uses the rivers as open sewers - people also used the same rivers for drinking and bathing. People were fined for dumping rubbish outside their houses - wealthy people just paid the small fine, and carried on littering, Butchers slaughtered animals in the street and dumped the remains in the river. Open sewers ran down the centre of streets. Disease spread quickly in this camped environment. The Solutions: Sign of the guild of Butchers. Laws were passed to ensure Butchers could only work in certain parts of the city - known as “Shambles” Trade Guilds ensured their members stuck by the Law. So Butchers had to comply - from the selling of fresh meat to where they could slaughter animals. Gong Farmers were employed to rake up and clean the tonnes of animal manure and human waste off the streets . Laws were passed ensuring people could not build a cesspit two and a half feet from a well. Sewers were built to take waste to the river . Public toilets were built. 10 SECTION EIGHT: 19TH CENTURY PUBLIC HEALTH The Government in the 19th Century was Laissez Faire (This is french for “leave it alone”) This meant the government did not believe in intervening in the lives, and in this case health of itʼs subjects. For the Government to engage in large public health projects would mean an unpopular raise in taxation. The people who wanted the government to say out of their affairs were known as “The Dirty Party” They wanted public health to be left up to individual rate payers and not a matter of national law. At the start of the 19th Century public health was in a similar state to that in the 14th Century - so what caused this to change? The Answer? Repeated Cholera epidemics Cholera hit london on a regular basis throughout the 19th Century. In 1832 after studying how the disease attacked /london people began to find a link between Cholera and the water supply - however at this time people did not understand that Germs were the real cause of this disease. After the Cholera breakout of 1854 Doctor John Snow used statistics and research to build up a detailed picture of the epidemic that seemed to effect only one area of London SECTION NINE: CHOLERA AND THE WORK OF JOHN SNOW. John Snow Observed the Victims from the area of London around Broad Street. He interviewed every household asking where they drew their water from. Even those who were not from the area but who had the disease were interviewed. He did notice that not everyone fro the area serviced by the Broad Street water pump did not contract the disease. 11 Snow discovered that the people not from the area who had contracted the disease - did so because they drew their water from the broad street pump. He also worked out that those who lived in the area but who had not contracted the disease were drinking beer not water. They were brewery employees. There was also a deep well within the brewery. (Beer was seen as a health food in the nineteenth century). Snow took the handle off the pump and observed the results...... the cases of cholera dropped off. Upon examination of the well it was found that a cess pool had broken itʼs wall and was leaking into the well in broad street. Snow was able to prove the connection between Cholera and water. Although Snow was able to prove a link between water and Cholera he was not able to show what Cholera looked like. It would take Louis Pasteur and his Germ Theory to show the existence of Germs. This problem meant that even though snow had meticulous research there would be doubters who would resist Government intervention. Snow was not the only person dealing with issues of Public Health in Britain at this time. .... 12 SECTION TEN: THE WORK OF EDWIN CHADWICK. Chadwick is one of the few medical Heroes who is not a scientist or a doctor he is a civil servant who was employed by The Poor Law Commission. Chadwickʼs Job was to assess who need help and to work out how much assistance they received from the taxes that were collected in his local area. At this time the poor were given financial help on a local basis - so each area had different rules. Today everyone in the country is entitled to the same benefits and medical cover paid for by national insurance contributions. Chadwick was tasked with producing a report on the Health of the poor in both town and country. Chadwick worked out : Chadwick suggested the rate payers could save the money they spent looking after the poor if our living conditions were improved. ....and the appointment of district medical officers with special qualifications.... We are only so poor because of our horrible living conditions which causes out bad health - this makes us unable to work. He also suggested that rate payers fund public drainage systems (Sewers) to keep streets clean and improve the health of the public At First the Government tried to ignore his report - However in 1848 a new Cholera Epidemic was breaking out - so the Government passed The public Health Act 1848. However the Government still wanted to remain Laissez Faire (Remember this term from page 11?) So they made the Law voluntary not Compulsory - this meant local authorities did not have to build the sewers if they chose not to - many chose not to. 13 However subsequent epidemics increased international competition especially from France the USA and Germany whose governments had invested in extensive public health projects meant that the productivity of Britainʼs workforce was falling behind its competition. The final piece in the puzzle was the improvement of the microscope by Joseph Lister and Louis Pasteurʼs Germ Theory and the Work of Robert Koch which eventually showed the bacteria that caused diseases such as Cholera. (See book one) By 1875 in the face of international competition and indisputable scientific evidence the British Government passed : The Public Health Act 1875. The Act ensured local Authorities had to provide by law: Proper Drainage Sewers Clean water Medical Officers Test Yourself: What factors would you use to describe why the british government passed the public Health Act 1875? What factors would you use to describe the reasons behind the passing of the Public Health Act 1848? What does “Laissez Faire” mean? How does this term apply to the British Government in the early 19th Century? How about the late 19th Century? 14 OTHER HEALTH REFORMS IN THE 19TH CENTURY 1802 - Factory Acts. Improved working conditions. 1889 Isolation hospitals for infectious diseases. Ones Husband Albert died of Typhoid Fever This disease effected all classes - it could have been due to poor drains. One was not amused 1852: Compulsory Vaccination. 1858 Regulation of Doctors Qualifications. 1876 Laws against the pollution of Rivers 1870 Improved Education. Every local authority had to set up schools Queen Victoria - the monarch for the majority of the 19th Century (1837 - 1901) 1876 Food Standards and building regulations. ANYTHING ELSE?...This fella: Who is he? An outstanding engineer he was the man who built the sewage system under London He set the template for all modern Sewage systems - this system helped stop the Cholera epidemics in London. This famous landmark was built to accommodate the system: Joseph Bazalgette 1819 -1891 The London Embankment. underneath is Bazalgettes sewage system. 15 SECTION ELEVEN: 20th and 21st CENTURY PUBLIC HEALTH From the 19th Century onwards successive British Governments began to see the wisdom of spending money to ensure the health and well being of the citizens. However most great changes tended to come because of a great emergency. In the 19th century it was the Small pox and Cholera epidemics which caused the government to pass the Public Health Acts and introduce compulsory Vaccinations. In the 20th Century is was War!. With Increased economic competition from countries such as Germany and the prospect of invasion and defeat caused the government to increase spending and investment in the Health of itʼs Public. 1911 The National insurance scheme was introduced - this provided payment for healthcare. 1914-1918 World War One: Medical advances such as plastic surgery blood transfusions, and mobile X-rays filter into civilian hospitals - Women doctors also become more common place. Education levels increase people are able to read and understand government health leaflets and posters. 1939 The Government start the “Emergency Hospital Scheme” Funded and Run by the government - this is the fore runner to the “National Health Service” 1943 The Beveridge Report proposes a “National Health Service” which will be free at the point of delivery to all British citizens. 1946 The National Health Service Act - provides a comprehensive healthcare system. 5th July 1948 The first day of the National Health Service (NHS) Free healthcare at the point of delivery. 16 The National Health Service is paid for by the Government from peoples National Insurance Contributions - this is an advanced version of the 1911 National Insurance Scheme. If you want to know what the NHS does for us please refer to page 46 of the SNHS Medicine and Health Through Time Book. PUBLIC HEALTH IN THE 21ST CENTURY. So where do we go from here? We understand how disease spreads we know what bacteria look like and how they cause disease. We have vaccination and inoculation programmes paid for by the National Health Service. We have excellent Public Health Service services such as clean water and sewage systems. We have a free at the point of delivery health service. What happens next.......? As we progress as a civilisation we (and our public health systems) face new challenges. Challenges such as: Epidemics and Pandemics (A pandemic is an epidemic that spreads from country to country )- remember the Bubonic and Pneumonic plagues? As they spread across the known world they became a pandemic! At the end of WW1 a strain of the flu known as Spanish Flu (So called as it was first reported in Spain) killed over 18 million people world wide (More than the first world war) Since then governments have co-operated and spent billions on combatting a variety of flu epidemics - such as Swine Flu and Avian Flu 17 Conditions such as the Human Immunodeficiency Virus (HIV) which can lead to Aquired Immunodeficiency Syndrome (AIDS) still need to be addressed. To combat these new challenges we need to have new levels of international co-operation and communication, Education Scientific development, Innovation, Individual Genius, Government investment, Corporate investment........ to name but a few of the factors we need to survive and prosper in the 21st Century.
