Hurt, Aeron C.; Besselaar, Terry G.; Daniels, Rod S.; Ermetal, Burcu; Fry, Alicia; Gubareva, Larisa; Huang, Weijuan; Lackenby, Angie; Lee, Raphael T.C.The World Health Organization (WHO) Collaborating Centres for Reference and Research on Influenza (WHO CCs) tested 13,312 viruses collected by WHO recognized National Influenza Centres between May 2014 and May 2015 to determine 50% inhibitory concentration (IC50) data for neuraminidase inhibitors (NAIs) oseltamivir, zanamivir, peramivir and laninamivir. Ninety-four per cent of the viruses tested by the WHO CCs ...

Respiratory syncytial virus epidemic periods in an equatorial city of Brazil
Moura, Fernanda E. A.; Perdigão, Anne Carolinne Bezerra; Ribeiro, Joyce F.; Florêncio, Caroline M. G. D.; Oliveira, Francisco M. S.Background Characterization of the human respiratory syncytial virus (HRSV) season at the local level has important implications for appropriate decisions on the time period for administration of specific prophylaxis. Objectives (1) To describe five consecutive epidemic periods of HRSV in an equatorial city of Brazil and (2) to show preliminary data on genomic diversity of circulating HRSV. Patients/Methods Nas...
Seasonality of influenza in the tropics : a distinct pattern in northeastern Br...
Perdigão, Anne Carolinne Bezerra; Siqueira, Marilda M.; Moura, Fernanda E. A.Influenza epidemics occur worldwide annually. The incidence of influenza shows a seasonal pattern in temperate areas, but little is known about influenza seasonality in tropical regions. The objective of this study was to determine the prevalence and the seasonal pattern of influenza infections in children living in the city of Fortaleza in northeastern Brazil. An indirect immunofluorescence assay was performed...
Antigenic and genomic characterization of adenovirus associated to respiratory ...
Moura, Fernanda E. A.; Mesquita, Jacó R. L. de; Portes, Silvana A. R; Ramos, Eduardo A. G.; Siqueira, Marilda M.From January to December 1998, nasopharyngeal aspirates were obtained from 482 children with acute respiratory infections attended in emergence department and wards of a teaching hospital in the city of Salvador, Brazil. The samples were tested for the presence of adenovirus by isolation in tissue culture and indirect immunofluorescence assay. Eleven adenoviruses were detected by both methods in the same clinic...
Serological findings during a measles outbreak occurring in a population with v...
Oliveira, Solange A.; Siqueira, Marilda M.; Costa, Antonio J.L.; Almeida, Maria T.C.; Nascimento, Jussara P.From March 1991 to April 1992, serum samples for IgM detection were collected from 112 clinical measles cases reported to the Health Department of Niterói, State of Rio de Janeiro. The positivity exceeded 90% for specimens collected from the 5th to the 29th day after the onset of the disease. After day 30 a decline in IgM detection was observed, although positivity has been detected up to 90 days after the onse...
Longitudinal study of acute respiratory diseases in Rio de Janeiro: occurrence ...
Nascimento, Jussara P.; Siqueira, Marilda M.; Sutmoller, Frits; Krawczuk, Murilo M.; Farias, Vivian de; Ferreira, Vanja; Rodrigues, Maria JoséInvestigamos, durante um período de 4 anos (1982 a 1985), a ocorrência de vírus em secreções de nasofaringe coletadas de crianças com menos de 5 anos de idade apresentando quadro clínico de infecção respiratória aguda (IRA), residentes na cidade do Rio de Janeiro. Foram encontrados todos os vírus conhecidos como associados a IRA, com excessão do vírus influenza C e parainfluenza 1, 2 e 4. Vírus foram isolados m...
