The outbreak of yellow fever in Barcelona in 1821. The evolutionary origins of yellow fever are most likely African. [1] [2] Phylogenetic analyses indicate that the virus originated from East or Central Africa, with transmission between primates and humans, and spread from there to West Africa. [3]
Yellow fever: 3,000 (2,000 in Norfolk, 1,000 in Portsmouth) [153] Third plague pandemic: 1855–1960 Worldwide Bubonic plague: 12–15 million (India and China) [154] [155] 1855–1857 Montevideo yellow fever epidemic 1855–1857 Montevideo, Uruguay: Yellow fever: 3,400 (first wave; 900, second wave; 2,500) [156] 1857 Lisbon yellow fever ...
The yellow fever epidemic occurred during late 1870, beginning in August to the end of the year. There were a total of 1235 deaths; 468 women and 767 men. [ 1 ] The epidemic ended due to the city following hygienic measures and the mosquitoes not surviving Barcelona's cold weather conditions in December 1870. [ 1 ]
Epidemics of the 19th century were faced without the medical advances that made 20th-century epidemics much rarer and less lethal. Micro-organisms (viruses and bacteria) had been discovered in the 18th century, but it was not until the late 19th century that the experiments of Lazzaro Spallanzani and Louis Pasteur disproved spontaneous generation conclusively, allowing germ theory and Robert ...
The first of the Sanitary Conferences was organized by the French Government in 1851 to standardize international quarantine regulations against the spread of cholera, plague, and yellow fever. In total 14 conferences took place from 1851 to 1938; the conferences played a major role in the formation of the Office international d'hygiène ...
Jesse William Lazear (May 2, 1866 – September 25, 1900) was an American physician. In 1900, he deliberately allowed a mosquito to bite him to prove his hypothesis that mosquitoes were the vector for yellow fever transmission.
There are more than 500 species of arboviruses, but in the 1930s only three were known to cause disease in humans: yellow fever virus, dengue virus and Pappataci fever virus. [202] More than 100 of such viruses are now known to cause human diseases including encephalitis. [203] Yellow fever is the most notorious disease caused by a flavivirus ...
Giuseppe Sanarelli (24 September 1865 – 6 April 1940) was an Italian bacteriologist who incorrectly identified the cause of yellow fever as a bacterium. It was however found later by Walter Reed that the bacterium Bacillus icterioides was a secondary infection. In 1897 he triggered the first major public debate on medical ethics when he ...
