| 2 | Epidemiological, prevention and control updates of yellow fever outbreak in Brazil显示文摘Yellow fever is an acute viral disease endemic to tropical countries, like Brazil, where, since the 1940 s, has no significant documented outbreaks similar to that observed between 2016/2018(2 045 confirmed cases and 677 deaths; caused by the sylvatic form).The principal manipulating factors inciting this change were absence of appropriate vaccination campaigns and increased urbanization & population growth in forest areas, with prevalence of the virus in the species inhabiting of these areas.The 2016/2018 outbreaks exhibited incidence in areas with historically low or no yellow fever virus activity, triggering a surge in recorded deaths-mainly in the Southeastern states of Brazil.The Brazilian government aggressively responded, reforming the countries' prophylactic measures, including vaccine implementation-as of March, 2018, switching from the former double dose regimen of the vaccine, to a single dose protocol, deemed as adequate.Moreover, some states appropriated the fractionated dosage(1/5 of the standard dose), in foresight of potential vaccine shortages.To prevent the uprising of new sylvatic yellow fever cases in Brazil, it's obligatory the development of effective combative plans, including adaptation of prophylactic measures individually(use of repellents, protective clothing etc.), applicable vaccination campaigns in every endemic region, to raise awareness to locals and visitors alike.Notwithstanding these preventative strategies, the persistence of cases and the recent outbreaks in Brazil, highlight the possible ineffectiveness of combative measures.Based on these considerations, the objective of this review was to raise more awareness of the epidemiological impact of the disease in Brazil. | Marli do Carmo Cupertino Rebeca Garcia Andréia Patrícia Gomes Sérgio Oliveira de Paula Nicholas Mayers Rodrigo Siqueira-Batista | 2019 | Asian Pacific Journal of Tropical Medicine2019，12，2： | 0 |
| 3 | Chemical Exposure Hazardous for Fish Hyphessobrycon eques through the Incorrect Release of Oil in Amazon Region显示文摘Incorrect discard of oil used by fishing ship in the brazilian north region has become a common activity.Despite the possible hazard to the aquatic organisms,still missing scientific data about their toxicity.Thus,this study aimed to evaluate the stress and lethality caused by lubricant oil(FSAOLU)on fish Hyphessobrycon eques.Therefore,it was used six different concentration diluted in water(0,22,24,26,28,30 and 32%of oil)and three replaces during 96 hours.At the end or during the experiment(with dying fish),it was collected blood samples(cutting the caudal fin)to determine physiological changes.The FSAOLU showed mean lethal dose(LD50-96h)of 27.36%,classified as toxic causing alterations in glucose values from the 26%.The greater dilution of FSAOLU(32%)increased 115%in glucose values when compared to the control.Thus,lubricant oil when discarded in water,it present hazard to the aquatic organisms causing stress and mortality for fish being necessary adequate management to discard of this residue. | Natalino da Costa Sousa Arthur dos Santos da Silva Keber Santos Costa Junior Francisco Alex Lima Barros Geisy Correa de Oliveira Pedro Rodrigo Nery de Souza Claudmilson Rodrigues de Mesquita Bruna de jesus Santos Alexander Damaceno Lima santos Winnícius Muniz dos Santos Sá Nayara Siqueira dos Santos Márcia Valéria Silva do Couto | 2020 | Journal of Fisheries Science2020，2，2： | 0 |
