Archaeologists in London have unearthed a mass grave of more than a dozen skeletons suspected to have died from plague during the 14th century when Europe was struggling to deal with 'Black Death' and the archaeologists predict that they will have more such skeletons as they excavate the site.
The Plague is by definition a re-emerging infectious disease which affects the lungs and is highly contagious, leading to mass outbreaks across populations. History shows us that population levels suffered globally due to the plague, with around 75 million people globally perishing during the 14th century Black Death.
AdvertisementThis study, published in Infection, Genetics and Evolution, analysed the Great Plague of Marseille, which caused 100,000 deaths between 1720 and 1723. The researchers aimed to highlight issues we are facing with infectious diseases today, to identify the best ways to respond to epidemics and whether we are still at risk of the plague re-emerging again.
Results show that a number of factors show we are still at risk of plague today. This is largely due to transport trade and novel threats in developing countries where multi-drug resistant pathogens are currently emerging and spreading rapidly. This genetic change has also contributed to a development in the way the bacteria infect new hosts meaning they can now live in mammalian blood.
The study also highlighted the need for effective management of epidemics in future. Fear of in infection can have a negative impact on a population's economic situation due to a significant loss of tourism, and widespread panic. History has shown us that providing the necessary information about diseases and improving the management of epidemics are vital steps for avoiding panic and containing diseases.
