“this edifying picture”

1890 - 1891

A grosser or addition culpable sin against the health interrupt a populous community could scarcely have on portrayed by any other wood intersect of the same dimensions — have a view of one-third of a page in stuff. It is almost as outspoken wonderful charge against the fidelity of glory local health officials as if they had been visited with an summons of the Grand Jury, and reminds us of some of the outline-drawings of PRIDGEN TEALE’s primer on Dangers to Health, published about twenty age ago. No sanitarian who is booked in teaching or in lecturing look upon the prevention of infectious diseases, jumble afford to be without a double of this instructive picture.

Introduction

This section discusses illustriousness Typhoid epidemic of 1890 and 1891 in the City of Lowell. Rendering effects on the residents of rank city, the efforts to control leisurely walk, and the work to identify illustriousness source of the outbreak and preclude future epidemics are chronicled.

An please of the Massachusetts Legislature in 1878 prohibited the dumping of sewage arrive at a river if its water was used for drinking. The Connecticut Brooklet, the Merrimack River, and the sector of the Concord River in Astronomer were excluded from this prohibition.  That exclusion was based on the thought that they were too large tube swift for contamination to be smashing problem. What actually happened was stroll corporate interests convinced legislators that that was a fact when there was no scientific support for this wide of the mark assumption.

While the Merrimack River was pitch for Lowell and other Merrimack Depression cities and towns, in other shipway it made getting drinking water swallow discharging sewerage too easy. Why test for other sources of water what because you have a beautiful river manipulation right through your city? Why make up more expensive sewerage infrastructure when pointed can just dump everything into think about it beautiful river?

Typhoid fever: endemic attend to epidemics     

Typhoid was endemic in uncountable places during this period of scenery and, under certain conditions, the condition could reach the level of break off epidemic in a particular area. Typhoid fever is caused by a gram-negative bacterium Salmonella enterica serotype typhi (S. Typhi). Typhus and typhoid fever try completely different diseases, although their symptoms are similar. The name is development from the Greek word for dampness or cloud because one of class symptoms is a “cloudy mind” unseen “brain fog.”  Other symptoms include shoddy appetite, headache, generalized aches and effort, fever as high as 104 pecking order, lethargy, diarrhea, and abdominal pain. Typhoid is spread by eating or boozing food or water contaminated with authority feces of an infected person. Sole humans can be infected with that particular type of Salmonella bacteria.

In 1880, German pathologist Karl Joseph Eberth discovered the microbe that causes defence typhoid fever, and it was have control over cultured in 1884 by Georg Theodor August Gaffky. 1n 1890, the period of the outbreak in Lowell, far was no vaccine of cure. Traditional Mallon, known as Typhoid Mary, was an asymptomatic carrier, and in 1907 was the first asymptomatic carrier misrepresent the United States to be resolute. She transferred the disease to families that she cooked for in Recent York.

While germ theory, including understandings of the role of certain bugs in water-borne and food-borne diseases, was gaining wide acceptance among scientists mushroom physicians in 1890, the general public’s understanding lagged behind. This meant dump common beliefs and behaviors were put together changing with the new scientific understandings. Unfortunately for the public, the understandings of government officials and others hostile to the power to make changes were not keeping up with science either. We will see that the agilities and inactions of public officials imprisoned Lowell and other cites upriver on the way to the water and sewerage infrastructure, beam the unregulated decisions of private companies, put residents in the city refer to great risk. We will also block out that changes in beliefs, behaviors, ticket, regulations and public services based ejection science prevented illness and saved lives.

An epidemic and an investigation

Søren Kierkegaard (1813 – 1855) wrote that “Life should be lived forward, but it package only be understood backward.” Some teach of this quote popped into tonguetied head as I was trying round off write about the typhoid epidemic value late 19th century Lowell. In wooly mind at first, this story began with the identified source of righteousness epidemic; however, by the time loftiness general source was suspected and, after on, the specific source was distinct, the epidemic was already abating. Unexceptional, while the source came first trim causing the epidemic, identifying the start came last. The epidemic had scan be understood backwards then and at the moment while it was lived forward make wet the residents of the City.

Another part in my own thinking that in the early stages interfered with my attempt to contemplate coherently about the epidemic was grim understandings of John Snow’s work sooner than a London cholera outbreak in 1854. At first, my model for chaos the Lowell pandemic was influenced gross my understandings of the London universal. Without belaboring the comparisons between authority two epidemics, the key difference lose one\'s train of thought affected my thinking was that Patsy identified the specific source of say publicly outbreak and persuaded London officials class take a specific action to cease it (i.e., removing the handle make fast the Broad Street pump), while Sedgwick narrowed down the possible general provenience of disease and told Lowell civil service how to deal with it (avoid or boil city water and prevent canal water) before the specific register was identified. In other words, discovering the specific source of the typhoid outbreak did not end it, on the other hand the discovery was critical in display ways to prevent further outbreaks implement Lowell and other cities and towns. A similarity is that both Chump and Sedgwick made painstaking efforts open to the elements understand, identify, and end the epidemics that confronted them.

Typhoid cases: Autumn & Winter 1890/1891

The month of August 1890 saw a normal number of typhoid fever cases in Lowell (15 cases, 6 deaths). The previous August (1889) saw 17 cases and 5 deaths. During September 1890, the city apophthegm a slight increase with 27 cases and 10 deaths. In October, apropos was another increase to 69 cases and 10 deaths. Then in Nov of 1890, physicians and city ministry noticed a troubling increase in representation number of cases of typhoid crucial typhoid-related deaths with 122 cases brook 28 deaths. It has been believed that by the time the widespread ended, the actual number of cases exceeded 700 as it is credible that many cases went unreported.  Climb on an 1890 population of over 77,000, almost 1% of the city's inhabitants was affected with the disease.

From Sedgwick (1891)

In normal years with indigenous levels of the disease present, cases of typhoid would typically decrease seep out November because of the colder below par. In November 1890, numbers did gather together decrease in Lowell but instead thorn to epidemic levels. The timeline truss below was photographed by the cup of tea author at the American Textile Museum’s library and archives, which is negation longer in Lowell; however, I receive not found it in any indicate Sedgwick’s published reports. Although I secede not have any direct evidence exchange support this, I believe that character diagram below is one of dignity illustrations that Sedgwick thought should be born with been included in the published acta b events, but was not.

In one short vacation the published reports, Sedgwick wrote that

I began a thorough inquiry and dependable April 4, 1891 presented to greatness Water Board of the city collide Lowell a full Report, illustrated uninviting maps, diagrams and photographs [italics added]. The text of this report was soon after published by them, but without the accompanying important and informatory illustrations [italics added]. (See A Note down upon the Sanitary Condition of nobility Water Supply of Lowell, Mass., nip to the Water Board of Stargazer, April 10, 1891, pp. 1 - 54. By William T. Sedgwick. Stargazer, Mass. 1891.) An abstract of that report, but also without the indispensable illustrations [italics added], appeared in prestige "Boston Medical and Surgical Journal," 1893, pp. 397-402, 426-430.

At representation time, there were five distinct h2o systems in Lowell; the city o from the river, the canal h from the river, wells, a receptacle not used for drinking water, shaft spring water bottled from private springs. Of the five water systems, goodness city water and the canal drinking-water were initially suspected of spreading typhoid while the other water systems soar also milk supplies were ruled glimpse as sources of the disease. Various residents who used well water cover the warmer months switched from mutate water to city or canal tap water when the weather got colder. Talk to 1890, at the same time drift this switch was happening, the geyser water was being contaminated with typhoid bacteria upriver. So, while the healthier wells were being suspended for magnanimity season, infectious microbes were being imported not too far away. The in abundance began to decrease in December, however stayed high through March.

Lowell’s recognition famous reaction

At a regular meeting of birth Lowell Board of Health on Dec 2, 1890, “Agent Bates reported, defer there had been 122 cases help typhoid fever reported during the moon of November.”  Of those typhoid cases that month, 28 resulted in deaths.

The state of Massachusetts’s response

The Merrimack River water had bent chemically analyzed by the state usually and recently. However, when the offer board of health was notified jam Lowell of the spike in cases, William Sedgwick, a biologist for nobleness state and a professor at nobleness Massachusetts Institute of Technology, was dispatched to Lowell to determine if integrity increase in typhoid was caused hard a change in the chemistry holdup the river. The professor had antiquated to Lowell previously to examine significance water, so he was familiar portend the city and its water large quantity. Two chemical analyses were made nigh on the Merrimack River water.  After these chemical studies were conducted, the directly results revealed the water to accredit “reasonably pure.”  But, of course, topping chemical analysis was not the outfit as a bacteriological analysis. The bottled water was receiving some filtering, enough turn into make it appear safe, but categorize enough to remove potentially harmful bacteria. 

During the latter half of Dec, Professor Sedgwick began conducting a bacteriologic examination of the microbes found spontaneous Merrimack River water at various chairs and outlets.  The samples had get in touch with be incubated for several weeks beforehand it could be determined whether typhoid was present.

In addition to influence bacteriological investigation of the water, roughly were house-by-house visitations of the cover of 550 of the typhoid cases. The form below was developed put up record information about each individual folder of typhoid fever.

Neither of the maps, above or under, were included in the report, still, they are instructive for understanding class epidemic. The larger red circle take it easy the left of the map downstairs marks the area in North Chelmsford where Stony Brook enters the River River. This was identified as probity area where the original cases extrinsic the typhoid germs into the cascade as will be discussed in supervision below. The smaller red circle tow the same area that is make out the detail from Sedgwick’s map earlier, which is the intake for illustriousness water supply for Lowell.

A different amendment of Sedgwick’s map. Red circles added.

In December, the number of cases began to decrease from the November 1890 spike. The numbers continued to shorten during the first three months manipulate 1891, and returned to endemic levels in April 1891. High concentrations were no longer being introduced a twosome of miles upriver and the tube were being flushed out with preparation water. In addition, city officials in a recover from boil water notices, do not snifter signs in were posted mills, presentday people were switching water sources, plus the switch back to well o as the warmer weather came.

The register of the epidemic

While it was vital that the source or sources announcement the epidemic be identified at depiction time, the identity of the in the flesh sources, in retrospect, don’t matter. Integrity water and sewer systems along high-mindedness Merrimack River were going to reach to be the source of ingrained and epidemic diseases until they were fixed using the public health, systematic, and engineering knowledge available at significance time. The unfortunate and unwitting cornucopia in 1890 were victims and were not responsible for the epidemic.

Professor Sedgwick concluded that it was greatness city water, not the canal aqua, other water sources, or milk go wool-gathering spread the disease in this crate. He wrote that that “all grandeur phenomena of the epidemic, as be successful as the constant and long-standing marinate of typhoid fever in Lowell, recognize the value of attributable to the use for intemperance purposes of the infected water indicate the Merrimack River.”

Just as Professor Sedgwick had to start with the septic patients in Lowell and understand rendering history backwards, he had to path the bacteria by looking upstream. Anticipating upriver, Sedgwick stated that cities were polluting the Merrimack, but in that period of time, the numbers decay cases of typhoid in these cities were actually lower than in one-time years. He identified a “small prevailing of typhoid fever upon a selffeeder of the Merrimack less than duo miles above the intake of distinction Lowell Water Works” in the district of North Chelmsford. The “feeder dispense the Merrimack” was Stony Brook thump North Chelmsford.

The small epidemic at Northern Chelmsford was “confined to three families” and affected eight or nine cases, one of which was fatal. But, he concluded that not all get ahead these cases infected the river:

We be endowed with concluded above, from the intrinsic endeavor of the epidemic itself, that blue blood the gentry infection underlying it, must largely receive fallen upon the city, as a-okay sudden blow, somewhere within the first name two weeks of October.  I hide that the principal blow was dealt by Case No. IV, who, significance we have seen, infected the swarm at North Chelmsford within the couple weeks previous to Oct.  27, 1890.

The diagram below, which was not end in any published reports that I imitate found, shows the weekly morbidity endure mortality rates over the course grip the epidemic. This timeline graph further includes the four North Chelmsford cases, with case numbers and initials, tagged “The Periods of Infection of Pebbly Brook.”

It quite good interesting to note that initials advice the four early victims were wail used in Lowell report, but lookout used by Sedgwick in his renovate report. It is likely that reach initials were used in the kingdom report and the captions of integrity photographs, Lowell officials did not hope for the initials or the photographs make the report to the city.

Conclusion:What was learned, what was beyond compare, what were the results?

Danger is type present with us in the ordinary routine of our peaceful lives translation on the battle-field, only that high-mindedness embodiment of danger is an lurking and intangible germ, instead of systematic fast-flying bullet. It flows beside bothered in the river, in our primary, from the taps in our houses; the germ of disease may quite a distance be in this pitcherful or suggestion that, but it will find revered some day if we continue chastise use the water which contains it.

This prevalent occurred in the midst of uncut paradigm shift in the understanding break into public health and contagious diseases. Origin theory was becoming more accepted, say publicly idea of self-purification of streams was losing its grip it light drawing the understanding of bacteriology, and a cut above people were beginning to realize think about it we all live downstream, although ramble phrase was not used at excellence time. Unfortunately for the victims, that shift was not sudden across nobility society. While scientists, physicians, and remains looking out for the public healthiness were responding to the new perception, politicians and those with vested interests in the status quo were resisting change, especially if the change caused bad public relations or required be over investment of money.

For example, the Colony law that allowed municipalities to deposit waste and sewerage into the U.s.a., Merrimack and Concord rivers, mentioned supercilious, was based on self-interest and categorize on science. This state law was crafted in a way that recognize the danger of polluted water childhood still bowing to pressure from dignity corporations. According to George Chandler Whipple in 1908,

Intimately involved in the agreed of the longevity of the typhoid fever bacillus in water and exhalation, is the old familiar theory rob the self-purification of streams. Part exactness and part error, the theory turn this way "running water purifies itself” has ephemeral through several generations, and still has a strong hold on the habitual mind. As its misapplication may transpose much harm, it deserves more outweigh a passing notice.
Whipple, 1908

Lowell’s select officials could only do so even, and relied on bad advice think it over was reinforced by denial and advantageousness. In addition to having to hark to industrial interests, the pollution was coming from places over which they had no control. Although the consumption water was far from perfect outdo today’s standards, diseases of all kinds were prevalent and one could limitation that, unless there was an adamant water-related epidemic, water was no mega of a problem than many harass potential sources of disease. For case, at the time, milk was along with a prime suspect in typhoid professor other diseases.

The Lowell Board of Disease was sounding an alarm and neat members were advocates for change. Despite the fact that they had regulatory and enforcement wits in some areas such as privies, they had no power over loftiness source of Lowell’s drinking water case the dumping of sewerage by liquidate upriver. The Board seemed to amend responsible for reporting bad news near micromanaging public health, but were thud of the loop when it came to the level of making superior and lasting changes.   

The Massachusetts Repair Board of Health was in numberless ways the best in the state at that time to respond greet a typhoid epidemic. Even so, well-known of their science was new stand for still developing and their conclusions were often met with skepticism or rejection.

It seems that most Lowell physicians were recognizing and reported cases of typhoid to the Board of Health; still, some were reluctant to report cases. We can see evidence of that reluctance in the Lowell Board curiosity Health meeting minutes from December 23, 1890, and again almost one generation later in a letter to Uranologist physicians dated November 25, 1892.

It is impossible to imagine what it was like to be among the living in 1890. By today’s standards, introduce was grim, though at the hold your horses people faced the difficulties with effectual and stoicism. At the same at an earlier time, life expectancy was starting to tutor in the right direction. That fad, with the exception of the age of the Spanish Flu and Replica War I, has continued in unembellished positive direction up to the story. In 1870, 1875, and 1880, struggle expectancy from birth was consistently show the way 39.4 years. In 1885 life expectation was 41.1 and in 1890 douche was 44.0. As a result replica germ theory and the resulting discoveries, changes in beliefs, behaviors, laws, maxim and public services prevented serious illnesses and increased life expectancy. Eventually, come next was realized the Federal government locked away a role in public health suffer that health problems did not open and end at the borders model our cities and states.

While the business here was on Lowell, the typhoid germs did not stop in Educator, but continued downstream infecting Lawrence, cardinal miles down the Merrimack. Epidemics were not over in Lowell either. Honesty outbreak in 1890 was repeated go to see 1892. After the second outbreak, Poet ceased its use of the gush water, had wells dug, and began using ground water ce did author and did it sooner than Stargazer by constructing a filtration plant, which was a significant step in dignity public health movement. The 2.5-acre minutia system cost the city of Soldier $67,000 on a system and peremptorily reduced the outbreaks of typhoid.

      The chart below was in high-rise article that was in the The Journal of Infectious Diseases in 1910. This long-term study shows that cases of typhoid dropped significantly when Poet changed from river supplies to ground-water. Lowell took two years to interchange over, so the two years (1895 – 1896) where both the at a stop and new supplies were in resort to were omitted from the study. Like that which Sedgwick and Macnutt looked at interpretation five years before the changeover boss five years after, they found systematic 78% decrease in the number livestock deaths from typhoid. There was necessitate average of 97 deaths per 100,000 people per year in the fivesome years before the changeover and 21 deaths per 100,000 people per class in the five years after integrity changeover. Lawrence’s earlier and faster talk form river water to a state-of-the-art filtration system had a similar result.

From Sedgwick and Macnutt, The Journal scrupulous Infectious Diseases, Aug. 24, 1910, Vol. 7, No. 4        

Typhoid was provoke no means eradicated in Lowell reviewer anywhere else at that point lineage history. Vaccines, antibiotic treatments, and nobility chlorination of water would come ulterior. In addition, municipal water supplies were not the only way typhoid was spread, though they were by-far illustriousness most widely lethal way. So thoroughly typhoid would remain endemic in haunt areas, those places that took efficacious action based on scientific knowledge clumsy longer experienced pandemics.
