“…However, in communities with less than 2,500 inhabitants, the risk is nearly 12 times higher than in cities with more than 20,000 inhabitants [157]. At the beginning of the 20th Century, the Mexican authorities decided to offer prizes for the capture of scorpions and in just one summer, between 80,000 and 100,000 Centruroides scorpions were collected [160]. In 1962, a pest control scheme was put into effect in several parts of Mexico, which involved, among other non-chemical control recommendations, placing ceramic tiles and metal sheets around the foundations of houses [161,162].…”

“…At the beginning of the 20th Century scorpionism by T. serrulatus and T. bahiensis in the the State of Minas Gerais was established as a serious public health issue. The Ezequiel Dias State Institute began to produce serum, and also offered financial rewards for the capture of scorpions so that the venom could be extracted to produce anti-scorpion serum; this inducement led to the capture of 107,533 specimens in 6 years [160]. Dias, in 1924 [160] already foresaw the need: a) to test molecules for chemical control b) to construct buildings that were unsuitable for the life and procreation of scorpions c) to take supplementary measures.…”

“…Some time after this pioneering work, the use of sulfurous gas and xylol was forbidden because as well as being extremely difficult to employ, it posed great risks to health and the natural environment. Dias [160] drew up a list of 18 construction features to reduce the risk of infestation by scorpions, which should be required by the sanitary authorities, together with those responsible for giving approval for new buildings. He paid special attention to the need to forbid woodsheds to be built in areas (closed or otherwise) near to dwellings.…”

“…Brazil is comprised within these scorpionism’ hot spots. Casualties with these arachnids have been described in the country since 1915 [ 11 ], the same period in which antivenom therapy for scorpion stings was also developed locally [ 12 ]. Notwithstanding, scorpionism is likely to be occurring in the area long before that.…”

Scorpion envenomation in Brazil: Current scenario and perspectives for containing an increasing health problem

et al. 2023

View full text Add to dashboard Cite

Opportunistic scorpion species can colonize urban environments, establishing high-density communities that enhance the chances of human accidents. This scenario has been taking place in Brazil, in which some Tityus species have taken city centers, causing an explosion in the number of scorpion envenoming cases. The characteristics of this scorpionism epidemic in Brazil is discussed in the present work. The number of Brazilian scorpion stings has surpassed 120,000 cases in 2017, and has been maintained above this number ever since, representing a more than 3-fold increase in 10 years, which was higher than the number of cases for most of the neglected tropical diseases in the country. The escalation in scorpionism cases is even higher in some regions of Brazil. Fortunately, the proportion of mild cases has also increased in the analyzed period, as well as the number of victims seeking for medical attention within the first hour after the accident. The species Tityus serrulatus, Tityus stigmurus, Tityus bahiensis, and Tityus obscurus are traditionally accountable for most of the scorpion accidents in different regions of Brazil, but other species deserve to be closely watched. Despite scorpionism being a notable health problem in Brazil, accident prevention and pest control regarding this venomous animal have not been properly addressed by the scientific community nor by policy makers. Therefore, this review also aims to point possible fields of research that could help to contain the aggravation of the current scorpionism landscape in Brazil.

“…Sobre isto, estimulará Souza Araújo a estudar a casa rural no Paraná e suas relações com a infestação pelo hemíptero, chegando este colaborador a formular uma Lei Estadual normatizando a construção de casas rurais higiênicas 12 . As primeiras experiências de laboratório para testar a ação de inseticidas sobre triatomíneos ocorreu em Belo Horizonte, entre 1920 e 1922, quando Ezequiel Dias, Samuel Libânio e Marques Lisbôa, ensaiaram gás cianídrico, xilol, acetileno, creolina, querosene, naftalina, sulfureto de carbono e gases de carvão em pedra, contra escorpiões e várias outras pragas domésticas (triatomíneos, baratas, percevejos, pulgas e ratos) 13 . Neste trabalho, os AA concluem principalmente que as fumigações de gases de enxofre aquecido (adicionado ou não a salitre do Chile, para diminuir umidade) eram eficazes para aplicação em recintos fechados na proporção ideal de 20gr de enxofre por metro cúbico, durante 24 horas.…”

Os primórdios do controle da doença de Chagas (em homenagem a Emmanuel Dias, pioneiro do controle, no centenário de seu nascimento)

Very soon Carlos Chagas took into account the need of trypanosomiasis control, considering its great social impact and geographical dispersion The vector was considered the more vulnerable target and housing improvement the basic strategy to face the disease. In parallel, it was required a more clinical visibility for the disease, as an argument for its control. The first concrete tentative occurred in 1918 when Souza Araújo dedicating his efforts in Paraná, trying housing improvement. He was followed by Ezequiel Dias et al, in 1921, employing chemical compounds against the vector, The chemical fight will be retaken by Emmanuel Dias in 1944, assaying several old compounds, fire thrower and cyanidric gas. In 1946, DDT showed to be ineffective, but one year later Dias & Pellegrino described the insecticide gammexane, highly effective against domestic triatomines. Working with Mario Pinotti, expanded trials occurred in Minas Gerais (Triangle Region), justifying the expansion of the campaign to other endemic regions, with the rationale of continuous work in contiguous areas. In 1957 Pedreira de Freitas proposed the selective spraying, which was the model for the future strategy of program evaluation, by SUVEN and SUCAN organizations. In 1975 the national program is reorganized, launching two national surveys (entomology and serology). In 1979 the new pyrethroid compounds are tried and im 1983 the national program is expanded. Transfusion transmitted Chagas Disease was studied since the 1950 by the Nussenzweig group in S. Paulo, showing to be vulnerable to chemoprophylaxis and blood donor pre transfusional serologic screening. Nevertheless, these preventive measures only were implemented in the 1980 decade, following the emergence of HIV/AIDS pandemic. Practically, since the pioneer essays, the control of Chagas Disease transmission showed to be efficient against vector and blood bank mechanisms, depending on continuity, educative support and political will.
