Oswaldo Cruzright Oswaldo Gonalves Cruz (b. August 5, 1872, So Luz de Paraitinga, So Paulo, Brazil; d. February 11, 1917, Petrpolis, Rio de Janeiro) was a Brazilian physician, bacteriologist, epidemiologist and public health officer and the founder of the Oswaldo Cruz Institute. Oswaldo Gonalves Cruz was born on August 5, 1872 in So Luis de Paraitinga, a small city in So Paulo State, to the physician Bento Gonalvez Cruz and Amlia Bulhes Cruz. Still 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 medical doctor with a thesis on water as vehicle for the propagation of microbes. Inspired by the great 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 names of this branch of science of that time. He was financed by his father-in-law, a wealthy Portuguese merchant. Back from Europe, Oswaldo Cruz found the seaport of Santos ravaged by a violent epidemic of bubonic plague that threatened to reach Rio de Janeiro and engaged himself immediately in the combat of this disease. The mayor of Rio de Janeiro authorized the construction of a plant for manufacturing the serum against the disease which had been developed at the Pasteur Institute by Alexandre Yersin and coworkers, and asked the institution for a scientist who could bring to Brazil this know-how. The Pasteur Institute responded that such a person was already available in Brazil and he was Dr. Oswaldo Cruz. Thus, on May 25, 1900, the Federal Serotherapy Institute destined to the production of sera and vaccines against the bubonic plague was created with the Baron Pedro Afonso as Director General and the young bacteriologist Oswaldo Cruz as Technical Director. The new Institute was established in the old farm of Manguinhos (Portuguese for mangrove) at the western shores of Guanabara Bay. In 1902, Cruz accepted the office of Director General of the new institute and soon amplified its scope of activities, now no longer restricted to the production of sera but also dedicated to basic and applied research and to the building of human resources. In the following year, Oswaldo Cruz was appointed Director General of Public Health, a position corresponding to that of a today's Minister of Health. Using the Federal Serotherapy Institute as technical-scientific base, he started a quick sucession of memorable sanitation campaigns. His first adversary: a yellow fever endemics, which had earned Rio de Janeiro the bad reputation of Foreigners' Grave. Between 1897 and 1906, 4,000 European immigrants had died there from this disease. Cruz was initially successfull in the sanitary campaign against the bubonic plague, to which end he used obligatory notification of cases, isolation of sick people, treatment with the sera produced at Manguinhos and extermination of the rats populating the city. In 1904, a smallpox epidemic was threatening the capital. In the course of the first five months of that year, nothing less than 1,800 persons had already been hospitalized. A law imposing smallpox vaccination of children in existence since 1837 had never had been put into practice. Thus, on June 9, 1904, following a proposal by Oswaldo Cruz, the government presented a bill to the Congress claiming for the reestablishment of the obligatory smallpox vaccination. The extremely rigid and severe provisions of this instrument terrified the people. Popular opposition against Oswaldo Cruz increased sharply and opposition newspapers started a violent campaign against this measure and the federal government in general. Members of the parliament and labor unions protested. An Anti-vaccination League was organized. On November 13th, the Vaccine Revolt exploded in Rio. Violent confrontations with the police ensued, with strikes, barricades, and shootings in the streets, as the population rose in protest against the government. On November 14, the Military Academy adhered to the revolt but the cadets where dispersed after an intense shooting. The government declared a state of siege. On November 16, the uprising was controlled and the obligatory vaccination was suspended. But in 1908, a violent smallpox epidemic made the people rush en masse to the vaccination units and Cruz was vindicated, and his merit, recognized. Among the international scientific community, his prestige was already uncontested. In 1907, on occasion of the 14th International Congress on Hygiene and Demography in Berlin, he was awarded with the gold medal in recognition of the sanitation of Rio de Janeiro, In 1909, Oswaldo Cruz retired from the position as Director General for Public Health, dedicating himself exclusively to the Manguinhos Institute, which has been named after him. From the Institute he organized important scientific expeditions, which allowed a better knowledge about the health and life conditions in the interior of the country and contributed to the colonization of different regions. He eradicated the urban yellow fever in the State of Par. His sanitation campaign in the state of Amazonas allowed concluding the construction of the Madeira-Mamor railroad, which was interrupted due to the great number of deaths of malaria and yellow fever among the workers. In 1913, he was elected a member of the Brazilian Academy of Arts and Letters. In 1915, due to health problems, he resigned from the direction of the Oswaldo Cruz Institute and moved to Petrpolis, a small city in the mountains near Rio. On August 18, 1916, he was elected mayor of that city and outlined an extensive urbanization project he should not see implanted. In the morning of February 11, 1917, with only 44 years of age, he passed away in consequence of a renal crisis. As a consequence of the short but fruitful life of Dr. Oswaldo Cruz, an extremely important scientific and health institution was born, which marked the beginning of experimental medicine in Brazil in many areas. It exherts strongly its influence to this day on Brazilian science, technology and public health. References -
