The latest DNA recovery and sequencing technologies have been used to reconstruct the genome of Yersinia pestis bacterium responsible for Black Death pandemic bubonic plague that spread across Europe in fourteenth century. was pieced together from total extracted skeletal remains four individuals excavated a large cemetery on site Royal Mint East Smithfield London, where more than 2,000 victims were buried 1348 1349. draft sequence does not differ substantially modern Y. strains, providing...
Studies of prehistoric patterns health and disease focus on interpretations the evidence from hard tissue remains past peoples. These are based observations living peoples sources stress which may be expected to leave a record in their bones teeth. One presumed source that has received wide attention recent literature is weaning. The process weaning often associated with elevated risks infant mortality morbidity because infants no longer receive passive immunity mothers, they exposed new...
The 19th century St. Thomas' Anglican churchyard in Belleville, Ontario, Canada is associated with a large and well-preserved infant skeletal collection (n = 149) good-quality parish records that document interments the graveyard (1821–1874). By using combination of historical demographic stable nitrogen isotope analyses on remains, respectively, general pattern extended nursing for about 14 months, introduction foods other than breast milk by around 5 months age, variation breast-feeding...
The worldwide spread of a novel influenza A (H1N1) virus in 2009 showed that remains significant health threat, even for individuals the prime life. This paper focuses on unusually high young adult mortality observed during Spanish flu pandemic 1918. Using historical records from Canada and U.S., we report peak at exact age 28 argue this increased resulted an early life exposure to previous Russian 1889–90. We posit specific instances, development immunological memory strain may lead...
Recent outbreaks of H5, H7, and H9 influenza A viruses in humans have served as a vivid reminder the potentially devastating effects that novel pandemic could exert on modern world. Those who survived infections with past been protected from subsequent antigenically similar pandemics through adaptive immunity. For example, during 2009 H1N1 "swine flu" pandemic, those exposed to circulated between 1918 1940s were at decreased risk for mortality result their previous It is also generally...
Abstract Until the last half of 20th century, infectious diseases dominated health profile northern North American Aboriginal communities. Research on 1918 influenza pandemic exemplifies some ways in which social context European contact and ensuing economic developments affected nature disease ecology as well frequency severity problem. To understand these impacts it is necessary to consider web interactions among multiple pathogens, biology human host, environment people lived. At very...
This study examines the roles of age, period, and cohort in influenza mortality trends over years 1959-2016 United States. First, we use Lexis surfaces based on Serfling models to highlight patterns as well identify lingering effects early-life exposure specific virus subtypes (e.g., H1N1, H3N2). Second, age-period-cohort (APC) methods explore APC linear changes slope these (contrasts). Our analyses reveal a series breakpoints where magnitude direction birth significantly change, mostly...
Analysis of Norway House Anglican parish registers during the I918 in- fluenza pandemic suggests that eighteen percent population perished in six weeks. Its strategic position fur trade and lack substantial provisions subarctic winter contributed to death rate. Population recovery occurred within five ten years, owing a modest post-epidemic marriage boom maintenance birth rates. records twentieth-century virgin soil epidemics may help develop models for early contact epidemics.
Several factors play critical roles in the geographic spread of infectious diseases, including movement people between communities and social economic structure groups communities. A mathematical model has been developed to examine individual shared impact these factors. This was applied 1918-1919 influenza epidemic three Aboriginal central Canada. Previously published results from simulations used parameter estimates for mobility patterns that were derived historical documents study...
