- Potential measles transmission risk in mass gatherings: Are we safe for the Olympic games-Rio 2016?(2016) NALI, Luiz Henrique da Silva; FUJITA, Dennis Minoru; SALVADOR, Felipe Scassi; FINK, Maria Cristina Domingues da Silva; ANDRADE JR., Heitor Franco de; PANNUTI, Claudio Sergio; LUNA, Expedito Jose de Albuquerque
- Fake news and covid-19: a concern due to the low vaccine coverage in Brazil(2022) FUJITA, Dennis Minoru; NALI, Luiz Henrique da Silva; SARTORI, Giselle Pacifico; GALISTEO, Andres Jimenez; JR, Heitor Franco de Andrade; LUNA, Expedito Jose de AlbuquerqueThis study comprised the application of a survey in Sao Paulo, Brazil, in 2 different periods of 2020: the beginning of the covid-19 pandemic and the disease's first peak (from March to April, 100 interviews) to the time of stability in case fatality rates (from May to July, 100 interviews); the questionnaire included was composed of 14 multiple-choice questions to evaluate the importance of mass communication channels, including social media, and the level of importance attributed to preventive measures at the beginning of the pandemic. The changes in people's behavior, even in a group with more schooling, which initially considered preventive measures to be very important (91%) but, in the second survey, was reduced to 82%. The reinforcement of preventive measures to reduce cases and deaths by covid-19 in Brazil is urgent, allied to recommendations with clear information on the importance of vaccination to avoid low rates as the current situation of vaccine coverage for preventable diseases.

- HUMAN TOXOPLASMOSIS OUTBREAKS AND THE AGENT INFECTING FORM. FINDINGS FROM A SYSTEMATIC REVIEW(2015) MEIRELES, Luciana Regina; EKMAN, Claudio Cesar Jaguaribe; ANDRADE JR., Heitor Franco de; ALBUQUERQUE, Expedito Jose deToxoplasmosis, a worldwide highly prevalent zoonotic infection, is transmitted either by the oocysts, from water and soil, or the tissue cysts, in raw or undercooked infected meat, of Toxoplasma gondii. An ongoing debate is whether there are differences between the clinical and epidemiological characteristics of the outbreaks due to one or the other infective form of the agent. We performed a systematic review, recovering 437 reported outbreaks of which 38 were selected. They were complete reports containing ascribed Toxoplasma infecting form, and clinical and demographic data. There was no gender or age group selection in the outbreaks, which were described more often in the Americas. A large number of individuals were affected when oocysts, associated with soil and water contaminated with cat feces, were considered the transmission source. Onset of symptoms occurred early when the infection was ascribed to meat tissue cysts (11.4 +/- 6.7 days) with sharpened temporal distribution of cases, while a broader and prolonged appearance of new cases was observed when oocysts in water were the source of the infection (20 +/- 7 days, p < 0.001). Such information may be useful in the design and implementation of control strategies.
- Case-control study of an outbreak of acute toxoplasmosis in an industrial plant in the state of São Paulo, Brazil(2012) EKMAN, Claudio Cesar Jaguaribe; CHIOSSI, Maria Fernanda do Valle; MEIRELES, Luciana Regina; ANDRADE JUNIOR, Heitor Franco de; FIGUEIREDO, Walter Manso; MARCIANO, Maria Aparecida Moraes; LUNA, Expedito Jose de AlbuquerqueFoodborne diseases represent operational risks in industrial restaurants. We described an outbreak of nine clustered cases of acute illness resembling acute toxoplasmosis in an industrial plant with 2300 employees. These patients and another 36 similar asymptomatic employees were diagnosed with anti-T. gondii IgG titer and avidity by ELISA. We excluded 14 patients based on high IgG avidity and chronic toxoplasmosis: 13 from controls and one from acute disease other than T. gondii infection. We also identified another three asymptomatic employees with T. gondii acute infection and also anti-T. gondii IgM positive as remaining acute cases. Case control study was conducted by interview in 11 acute infections and 20 negative controls. The ingestion of green vegetables, but not meat or water, was observed to be associated with the incidence of acute disease. These data reinforce the importance of sanitation control in industrial restaurants and also demonstrate the need for improvement in quality control regarding vegetables at risk for T. gondii oocyst contamination. We emphasized the accurate diagnosis of indexed cases and the detection of asymptomatic infections to determine the extent of the toxoplasmosis outbreak.
