A public health risk assessment for yellow fever vaccination: a model exemplified by an outbreak in the state of São Paulo, Brazil

Abstract: We propose a method to analyse the 2009 outbreak in the region of Botucatu in the state of São Paulo (SP), Brazil, when 28 yellow fever (YF) cases were confirmed, including 11 deaths. At the time of the outbreak, the Secretary of Health of the State of São Paulo vaccinated one million people, causing the death of five individuals, an unprecedented number of YF vaccine-induced fatalities. We apply a mathematical model described previously to optimise the proportion of people who should be vaccinated to minimise… Show more

“…The importance assignment phase according to the comparator scale is considered one of the most important steps in the definition of risk areas, since the values awarded to a factor directly impact the obtained result. The weights attributed to the physical-environmental elements used in this study were defined according to the importance conferred by several health secretaries on the factors related to YF occurrence, 23 and the factors of the existence of non-human primates Alouatta and Callithrix , presence of mosquitoes, and land cover and use with forest formations were awarded the greatest importance. Transitioning biomes, such as savanna formation and groves were awarded intermediate importance and the urban area category was awarded the lowest value in the analysis, since the present study aimed to analyse the sylvatic form of YF.…”

“…Estes vetores alimentam-se preferencialmente de primatas não humanos e, secundariamente, do homem (SAAD & BARATA, 2016;SVS;. Nestes casos, os primatas não humanos (PNH) são os principais hospedeiros e amplificadores do vírus, já o ser humano é hospedeiro acidental, que se infecta, quando não devidamente imunizado, ao entrar em uma área de mata em ambientes rurais ou silvestres no período em que a circulação viral esteja ocorrendo (RIBEIRO et al, 2005;MASCHERETTI et al, 2009).…”

“…A pesar de não existir vacina antirrábica para animais silvestres, a vacinação anual de cães e gatos é eficaz na prevenção da Raiva nesses animais, o que consequentemente previne também a Raiva humana. De acordo com Tauil, P. L. (2010) eRibeiro et al (2005), quando se trata da vacinação de toda a população brasileira, algumas questões entram em discussão, como a existência de grupos populacionais com contraindicação da vacina (imunossuprimidos, pessoas em tratamento de neoplasias malignas, portadores de alergias a proteínas do ovo, mulheres grávidas e pessoas com mais de 60 anos) e até mesmo o risco de óbito. O ideal é que se mantenha uma alta cobertura vacinal nas áreas consideradas de risco(RIBEIRO et al, 2005).Segundo o Ministério da Saúde (2019), desde 2017 a Organização Mundial da Saúde recomenda que seja tomada uma dose da vacina para FA, o que é suficiente para garantir imunidade e proteção para toda a vida, em contrapartida, de acordo com Medeiros (2018), devido à epidemia ocorrida em 2016/2017 se fez necessário um grande volume de doses de que não havia disponibilidade no curto prazo.…”

“…To estimate all P(dead|RF) of the 48 RF, a simple survey based on the Delphi method was elaborated [9][10][11]. In this survey, veterinarians were invited to evaluate these 48 RF and to assign a grade in a Likert scale [12] from 0 to 10 for each RF.…”
