Dysentery epidemic killed many in the 1700s-1800s

25.10.2012
In the 1700s-1800s, dysentery was a disease causing many deaths. In fact, in some areas in Sweden 90 percent of all deaths were due to dysentery during the worst outbreaks.

A new doctoral thesis in history from the University of Gothenburg, Sweden, presents demographic and medical history of the disease.

Dysentery, or rödsot as it used to be called in Swedish, remains a major problem in developing countries. In the Western world, however, the disease is almost gone. Yet prior to the decline in infectious diseases among causes of death in the 1800s, Sweden was at times struck very hard by the disease, with catastrophic consequences.

‘The disease had detrimental effects, but the geographical differences were significant. For example, 90 percent of all deaths in a parish could be due to dysentery in some years, while nearby parishes were left practically unaffected,’ says the author of the thesis, Helene Castenbrandt.

Castenbrandt studied how the disease struck Sweden during the period 1750-1900, with a focus on changes over time as well as regional and local differences. Jönköping County was used as a case study. Besides demographic data, she also used parish registers, maps, newspapers, reports from medical district officers and other information written down by doctors.

Many historians have described dysentery as a regularly recurring and not very serious disease. Cholera and smallpox are often described as the most devastating epidemic diseases of that era. But Castenbrandt’s results beg to differ.

‘My study points to dysentery as very epidemic in nature. The disease struck communities extremely hard at times. It flared up quite irregularly and the patterns of transmission differed from one outbreak to the next.’

Using Jönköping County as an example, the study clearly shows the vast differences in dysentery mortality within the same county. The pattern of transmission for the three most severe outbreaks in 1773, 1808 and 1857 shows that although the disease spread across almost the entire county, there were some clusters with extremely high mortality. However, the hardest hit parts of the county varied.

The thesis also analyses the reasons behind the presence and disappearance of the disease. The results point to complex links between possible explanations such as sanitary conditions and population concentrations for example in connection with wars.

‘It is likely that many factors interacted, which makes it difficult to identify one single reason why dysentery emerged and disappeared. I hope future studies will be able to explore these links,’ says Castenbrandt.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
