100 Years: The Rockefeller Foundation | Yellow Fever · Health - 0 views

  • In 1915 the International Health Division (IHD) made the research and eradication of yellow fever and malaria its top priorities. While the organization achieved success in both campaigns, its yellow fever initiative yielded the clearest positive results. Before World War II, the IHD expended half of its budget on yellow fever programs, which culminated in the development of a successful yellow fever vaccine. This funding also contributed to the building of a wide and effective network of research laboratories, as well as the development of important scientific careers through support for individual fellowships. 
  • Mosquito transmission as the cause of yellow fever was first proposed by Carlos Finlay in 1881 and proven by Major Walter Reed of the US Army in 1900. This discovery led General William C. Gorgas to implement anti-mosquito measures while supervising the building of the Panama Canal; earlier attempts at construction had failed partly because of the prevalence of yellow fever among workers.  Once the canal was completed, many public health experts feared that increased international travel and shipping would lead to a sudden expansion of the disease.
  • Concern about the spread of yellow fever prompted Rockefeller Foundation (RF) interest in eradicating yellow fever. After Gorgas’ success in mosquito control in Panama, the RF recruited him in 1916 to chair the newly formed Yellow Fever Commission and to direct its efforts in eradication. Gorgas focused on vector control. He aimed to destroy mosquito breeding grounds in key communities, or “seedbeds,” where the aedes aegypti mosquitoes lived alongside a non-immune population. The first successful IHD campaign in yellow fever eradication took place in Guayaquil, Ecuador.

  • More ambitious projects were to follow. One of the most significant campaigns began in 1923 when the Brazilian Government requested IHD assistance in its efforts to eradicate yellow fever. For the next 17 years the IHD took the lead role in this campaign and even after the Brazilian Government took charge of the program in 1940, the IHD remained involved, contributing major support towards the cost of field work and lab tests
  • Although its early work in yellow fever was concentrated in South America, the IHD began to redirect a large portion of its funding to Africa in 1929. In that year the agency established its first African research laboratory in Lagos, Nigeria, and created the West Africa Yellow Fever Commission
  • His death was mourned by the medical community, who viewed him as a “martyr to science.”[3] Noguchi was one of six RF researchers who died while studying yellow fever, a statistic that almost caused IHD Director Frederick F. Russell to abandon the campaign against the disease. 
  • During World War II, the RF was asked to coordinate the vaccination of American and British military personnel.  However, in 1942, outbreaks of jaundice were reported among some military personnel who had been vaccinated with 17D. In total 8 million doses of vaccine had been administered to soldiers, 80,000 of whom developed jaundice, resulting in 81 deaths. Further research revealed that the cases occurred in soldiers injected with particular batches of the vaccine that had been tainted by infected human blood. Vaccinations were halted until a new vaccine containing no human serum could be produced. [5]

  • Today a new study suggests that the U.S. government`s billion dollar stockpile of flu medicine may have little effect in a pandemic. The government amassed enough flu medicine for sixty-five million people and the risk can be high. The outbreak of 1918, for example, killed more than six hundred thousand Americans. Doctor Jon LaPook has been looking into this new study.

1918 Flu Pandemic That Killed 50 Million Originated in China, Historians Say - 0 views

  • The global flu outbreak of 1918 killed 50 million people worldwide, ranking as one of the deadliest epidemics in history.
  • The deadly "Spanish flu" claimed more lives than World War I, which ended the same year the pandemic struck. Now, new research is placing the flu's emergence in a forgotten episode of World War I: the shipment of Chinese laborers across Canada in sealed train cars.
  • The 1918 flu pandemic struck in three waves across the globe, starting in the spring of that year, and is tied to a strain of H1N1 influenza ancestral to ones still virulent today.

Smallpox Definition - Diseases and Conditions - Mayo Clinic - 0 views

  • Smallpox is a contagious, disfiguring and often deadly disease that has affected humans for thousands of years. Naturally occurring smallpox was eradicated worldwide by 1980 — the result of an unprecedented global immunization campaign. Stockpiles of smallpox virus have been kept for research purposes. This has led to concerns that smallpox could someday be used as a biological warfare agent. There's no treatment or cure for smallpox. A vaccine can prevent smallpox, but the risk of the vaccine's side effects is too high to currently justify routine vaccination for people at low risk of exposure to the smallpox virus.

  • Mary Mallon, now known as Typhoid Mary, seemed a healthy woman when a health inspector knocked on her door in 1907, yet she was the cause of several typhoid outbreaks. Since Mary was the first "healthy carrier" of typhoid fever in the United States, she did not understand how someone not sick could spread disease -- so she tried to fight back.

  • footprints were spotted leading from the house to a chair placed next to a fence. Over the fence was a neighbor's property. They spent five hours searching both properties, until, finally, they found "a tiny scrap of blue calico caught in the door of the areaway closet under the high outside stairway leading to the front door."4
  • Mary was on the lookout and peered out, a long kitchen fork in her hand like a rapier. As she lunged at me with the fork, I stepped back, recoiled on the policeman and so confused matters that, by the time we got through the door, Mary had disappeared. 'Disappear' is too matter-of-fact a word; she had completely vanished.3

      The story/history of Typhoid Mary
  • After a trial and then a short run from health officials, Typhoid Mary was recaptured and forced to live in relative seclusion upon North Brother Island off New York. Who was Mary Mallon and how did she spread typhoid fever? An Investigation
  • For the summer of 1906, New York banker Charles Henry Warren wanted to take his family on vacation. They rented a summer home from George Thompson and his wife in Oyster Bay, Long Island. Also for the summer, the Warrens hired Marry Mallon to be their cook.
  • On August 27, one of the Warren's daughters became ill with typhoid fever. Soon, Mrs. Warren and two maids became ill; followed by the gardener and another Warren daughter. In total, six of the eleven people in the house came down with typhoid. Since the common way typhoid spread was through water or food sources, the owners of the home feared they would not be able to rent the property again without first discovering the source of the outbreak. The Thompsons first hired investigators to find the cause, but they were unsuccessful. Then the Thompsons hired George Soper, a civil engineer with experience in typhoid fever outbreaks. It was Soper who believed the recently hired cook, Mary Mallon, was the cause. Mallon had left the Warren's approximately three weeks after the outbreak. Soper began to research her employment history for more clues. Mary Mallon was born on September 23, 1869 in Cookstown, Ireland. According to what she told friends, Mallon emigrated to America around the age of 15. Like most Irish immigrant women, Mallon found a job as a domestic servant. Finding she had a talent for cooking, Mallon became a cook, which paid better wages than many other domestic service positions. Soper was able to trace Mallon's employment history back to 1
  • 900. He found that typhoid outbreaks had followed Mallon from job to job. From 1900 to 1907, Soper found that Mallon had worked at seven jobs in which 22 people had become ill, including one young girl who died, with typhoid fever shortly after Mallon had come to work for them.1 Soper was satisfied that this was much more than a coincidence; yet, he needed stool and blood samples from Mallon to scientifically prove she was the carrier.

Debating Death and Disease: Student Research Center - powered by EBSCOhost - 0 views

    • Jacob Morrison
       
      Intriguingly, just as the Black Death had a significant impact on European society, so its study has had a major impact on medieval historiography, leading to a series of dramatic debates, in particular over the identity of the disease. The debate was largely sparked by Samuel Cohn, who threw doubt on the long-held belief that the cause of the Black Death was bubonic plague in The Black Death Transformed: Disease and Culture in Early Renaissance Europe (2002). In 2010 DNA analysis by an international team of scientists identified Yersinia pestis, the pathogen responsible for plague, in medieval burial sites in five European countries (see the online article, S. Haensch, R. Bianucci, et al, 'Distinct clones of Yersinia pestis caused by the Black Death' These findings have now been absorbed by the historical community, as can be seen in articles in the recent volume edited by Linda Clark and Carole Radcliffe, 'Society in an Age of Plague' in The Fifteenth Century, XII (2013), but it has been questioned how far these very local findings can be generalized - and so the debate continues.

influenza pandemic of 1918-19 -- Encyclopedia Britannica - 0 views

  • influenza pandemic of 1918–19, also called Spanish influenza pandemic or Spanish flu,  the most severe influenza outbreak of the 20th century and, in terms of total numbers of deaths, among the most devastating pandemics in human history.
  • Influenza is caused by a virus that is transmitted from person to person through airborne respiratory secretions. An outbreak can occur if a new strain of influenza virus emerges against which the population has no immunity. The influenza pandemic of 1918–19 resulted from such an occurrence and affected populations throughout the world. An influenza virus called influenza type A subtype H1N1 is now known to have been the cause of the extreme mortality of this pandemic, which resulted in an estimated 25 million deaths, though some researchers have projected that it caused as many as 40–50 million deaths.

  • n, Kansas, U.S., in early March 1918. American troops that arrived in western Europe in April are thought to have brought the virus with them, and by July it had spread to Poland. The first wave of influenza was comparatively mild; however, during the summer a more lethal type of disease was recognized, and this form fully emerged in August 1918. Pneumonia often developed quickly, with death usually coming two days after the first indications of the flu. For example, at Camp Devens, Massachusetts, U.S., six days after the first case of influenza was reported, there were 6,674 cases. The third wave of the pandemic occurred in the following winter, and by the spring the virus had run its course. In the two later waves about half the deaths were among 20- to 40-year-olds, an unusual mortality age pattern for influenza.
  • Outbreaks of the flu occurred in nearly every inhabited part of the world, first in ports, then spreading from city to city along the main transportation routes. India is believed to have suffered at least 12,500,000 deaths during the pandemic, and the disease reached distant islands in the South Pacific, including New Zealand and Samoa. In the United States about 550,000 people died. Altogether an estimated 25,000,000 persons throughout the world perished, most during the brutal second and third waves. Other outbreaks of Spanish influenza occurred in the 1920s, but with declining virulence

Spanish flu mystery: Why don't scientists understand the 1918 flu even after digging up... - 1 views

  • Ninety-five years ago in the little town of Brevig Mission, Alaska, a deadly new virus called Spanish influenza struck quickly and brutally. It killed 90 percent of the town’s Inuit population, leaving scores of corpses that few survivors were willing to touch.
  • The miners arrived in Brevig Mission shortly after the medical calamity, tossed the victims into a pit two meters deep, and covered them with permafrost.
  • The flu victims remained untouched until 1951, when a team of scientists dug up the bodies, cracked open four cadavers’ rib cages, scooped out chunks of their lungs, and studied the tissue in a lab.
  • ...4 more annotations...
  • Spanish influenza killed about 50 million people (estimates vary), including 675,000 in the United States, and up to 40 percent of the world’s population was stricken with the flu.
  • Nearly 50 years later, scientists dug up another victim from the same site, this time a better preserved, mostly frozen, obese woman, and successfully extracted viral RNA. In 2005, a team of scientists finally completed the project, sequencing the full genome of the viral RNA. But they still don’t know exactly why it caused the Spanish flu pandemic.   
  • Horrifying as the flu was, its reign of terror was mercifully brief: By late 1919, the flu had largely disappeared. Although its survivors and their children faced lifelong health problems, those dark years were largely struck from cultural memory.
  • Scientists, however, never forgot the mysterious pandemic, and research into the 1918 flu experienced something of a renaissance in recent years. In addition to the exhumed Inuit, scientists have studied the organs of flu-suffering soldiers, including a long-forgotten piece of lung tissue stored at a military pathology institute in Washington.
