Oswaldo Cruz (neighborhood)
Oswaldo Gonçalves Cruz, better known as Oswaldo Cruz (; August 5, 1872 – February 11, 1917), was a Brazilian physician, pioneer bacteriologist, epidemiologist and public health officer and the founder of the Oswaldo Cruz Institute. He occupied the fifth chair of the Brazilian Academy of Letters from 1912 until his death in 1917. Early years Oswaldo Gonçalves Cruz was born on August 5, 1872 in São Luis do Paraitinga, a small city in São Paulo Province, to the physician Bento Gonçalvez Cruz and Amália Bulhões Cruz. As a child, he moved to Rio de Janeiro with his family. At the age of 15 he started to study at the Faculty of Medicine of Rio de Janeiro and in 1892 he graduated as a medical doctor, with a thesis on water as vehicle for the propagation of microbes. Inspired by the work of Louis Pasteur, who had developed the germ theory of disease, four years later he went to Paris to specialize in bacteriology at the Pasteur Institute, which gathered the great nam ...

Bacteriology
Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. Because of the similarity of thinking and working with microorganisms other than bacteria, such as protozoa, fungi, and viruses, there has been a tendency for the field of bacteriology to extend as microbiology. The terms were formerly often used interchangeably. However, bacteriology can be classified as a distinct science. Overview Definition Bacteriology is the study of bacteria and their relation to medicine. Bacteriology evolved from physicians needing to apply the germ theory to address the concerns relating to disease spreading in hospitals the 19th century. Identification and characterizing of bacteria being associated to diseases led to advances in pathogenic bacteriology. K ...

Vaccine Revolt
The Vaccine Revolt or Vaccine Rebellion (Portuguese: ''Revolta da Vacina'') was a period of civil disorder which occurred in the city of Rio de Janeiro, Brazil (November 10–18, 1904). Background At the beginning of the 20th century the city of Rio de Janeiro, then capital of Brazil, although praised for its beautiful palaces and mansions, suffered from serious inadequacies in basic infrastructure. Such problems included insufficient water and sewer systems, irregular garbage collection, and overcrowded tenements. Many illnesses proliferated in this environment, including tuberculosis, measles, typhus and leprosy. Epidemics of yellow fever, smallpox and bubonic plague occurred on an intermittent basis. Yellow fever was by far the most serious of the three, killing an estimated 60,000 Rio de Janeiro residents between 1850 and 1908. Although there were periods of respite from this particular disease, these were almost invariably marred by lesser outbreaks of the others. Beginning ...

Smallpox
Smallpox was an infectious disease caused by variola virus (often called smallpox virus) which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making it the only human disease to be eradicated. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was spread between people or via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medication may have helped. The risk of death was about 30%, with higher rates among babies. Often, those who survived had extensive scarring of their ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Yellow Fever
Yellow fever is a viral disease of typically short duration. In most cases, symptoms include fever, chills, loss of appetite, nausea, muscle pains – particularly in the back – and headaches. Symptoms typically improve within five days. In about 15% of people, within a day of improving the fever comes back, abdominal pain occurs, and liver damage begins causing yellow skin. If this occurs, the risk of bleeding and kidney problems is increased. The disease is caused by the yellow fever virus and is spread by the bite of an infected mosquito. It infects humans, other primates, and several types of mosquitoes. In cities, it is spread primarily by ''Aedes aegypti'', a type of mosquito found throughout the tropics and subtropics. The virus is an RNA virus of the genus ''Flavivirus''. The disease may be difficult to tell apart from other illnesses, especially in the early stages. To confirm a suspected case, blood-sample testing with polymerase chain reaction is required. A saf ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sanitation
Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route.SuSanA (2008)Towards more sustainable sanitation solutions Sustainable Sanitation Alliance (SuSanA) For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis (a type of intestinal worm infection or helminthiasis), cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few. A range of sanitation technologies and approaches exists. Some examples are community-led total sanitation ...

Guanabara Bay
Guanabara Bay ( pt, Baía de Guanabara, ) is an oceanic bay located in Southeast Brazil in the state of Rio de Janeiro. On its western shore lie the cities of Rio de Janeiro and Duque de Caxias, and on its eastern shore the cities of Niterói and São Gonçalo. Four other municipalities surround the bay's shores. Guanabara Bay is the second largest bay in area in Brazil (after the All Saints' Bay), at , with a perimeter of . Guanabara Bay is long and wide at its maximum. Its wide mouth is flanked at the eastern tip by the Pico do Papagaio (Parrot's Peak) and the western tip by Pão de Açúcar (Sugar Loaf). The name Guanabara comes from the Tupi language, ''goanã-pará'', from ''gwa'' "bay", plus ''nã'' "similar to" and ''ba'ra'' "sea". Traditionally, it is also translated as "the bosom of sea". History Guanabara Bay was first encountered by Europeans on January 1, 1502, when one of the Portuguese explorers Gaspar de Lemos and Gonçalo Coelho arrived on its shores. Accor ...

Vaccine
A vaccine is a biological Dosage form, preparation that provides active acquired immunity to a particular infectious disease, infectious or cancer, malignant disease. The safety and effectiveness of vaccines has been widely studied and verified. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or Antigen, killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylaxis, prophylactic (to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogen), or therapeutic vaccines, therapeutic (to fight a disease that has already occurred, such as cancer vaccine, cancer).

Antiserum
Antiserum is a blood serum containing monoclonal or polyclonal antibodies that is used to spread passive immunity to many diseases via blood donation (plasmapheresis). For example, convalescent serum, passive antibody transfusion from a previous human survivor, used to be the only known effective treatment for ebola infection with a high success rate of 7 out of 8 patients surviving. Antisera are widely used in diagnostic virology laboratories. The most common use of antiserum in humans is as antitoxin or antivenom to treat envenomation. Serum therapy, also known as serotherapy, describes the treatment of infectious disease using the serum of animals that have been immunized against the specific organisms or their product, to which the disease is supposedly referable. History In 1890, Emil Behring and Kitasato Shibasaburō published their first paper on serum therapy. Behring had pioneered the technique, using guinea pigs to produce serum. Based on his observation that people ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Alexandre Yersin
Alexandre Emile Jean Yersin (22 September 1863 – 1 March 1943) was a Swiss- French physician and bacteriologist. He is remembered as the co-discoverer of the bacillus responsible for the bubonic plague or pest, which was later named in his honour: ''Yersinia pestis''. Another bacteriologist, the Japanese physician Kitasato Shibasaburō, is often credited with independently identifying the bacterium a few days earlier, but may have identified a different bacterium and not the pathogen-causing plague. Yersin also demonstrated for the first time that the same bacillus was present in the rodent as well as in the human disease, thus underlining the possible means of transmission. Early life and education Yersin was born in 1863 in Aubonne, in the canton of Vaud, Switzerland, as the posthumous son of Jean-Alexandre-Marc Yersin from his wife Fanny-Isaline-Emilie Moschell. From 1883 to 1884 he studied medicine at Lausanne, followed by Marburg, and Paris (1884–1886). Career In 1 ...

Rio De Janeiro
Rio de Janeiro ( , , ; literally 'River of January'), or simply Rio, is the capital of the state of the same name, Brazil's third-most populous state, and the second-most populous city in Brazil, after São Paulo. Listed by the GaWC as a beta global city, Rio de Janeiro is the sixth-most populous city in the Americas. Part of the city has been designated as a World Heritage Site, named "Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea", on 1 July 2012 as a Cultural Landscape. Founded in 1565 by the Portuguese, the city was initially the seat of the Captaincy of Rio de Janeiro, a domain of the Portuguese Empire. In 1763, it became the capital of the State of Brazil, a state of the Portuguese Empire. In 1808, when the Portuguese Royal Court moved to Brazil, Rio de Janeiro became the seat of the court of Queen Maria I of Portugal. She subsequently, under the leadership of her son the prince regent João VI of Portugal, raised Brazil to the dignity of a k ...

Bubonic Plague
Bubonic plague is one of three types of plague caused by the plague bacterium (''Yersinia pestis''). One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting, as well as swollen and painful lymph nodes occurring in the area closest to where the bacteria entered the skin. Acral necrosis, the dark discoloration of skin, is another symptom. Occasionally, swollen lymph nodes, known as "buboes," may break open. The three types of plague are the result of the route of infection: bubonic plague, septicemic plague, and pneumonic plague. Bubonic plague is mainly spread by infected fleas from small animals. It may also result from exposure to the body fluids from a dead plague-infected animal. Mammals such as rabbits, hares, and some cat species are susceptible to bubonic plague, and typically die upon contraction. In the bubonic form of plague, the bacteria enter through the skin through a flea bite and travel ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
