Epidemiologic surveillance of respiratory virus in hospitalized childrens during three consecutive winter seasons in Maipú, Chile

Respiratory Infection in Chile (1989 to 2000) in Infants Hospitalized for Acute Lower Surveillance for Respiratory Syncytial Virus

Surveillance for respiratory syncytial virus in infants hospitalized for acute lower respiratory infection in Chile (1989 to 2000).

Hospitalized infants (4,618) were studied for lower respiratory infections from 1989 through 2000 by routine immunofluorescence assay and viral isolation. The hospitalization rate for respiratory syncytial virus (RSV) averaged 2% per year. The fatality rate was 0.1%. Monthly RSV detection varied from 14 to 88%, and epidemics lasted 3.5 to 6 months. From 1994 high-early versus low-late epidemic ...

Genetic diversity of human respiratory syncytial virus isolated among children with acute respiratory infections in Southern Cameroon during three consecutive epidemic seasons, 2011–2013

Background Human respiratory syncytial virus (HRSV) is the main viral cause of severe lower respiratory tract disease in infants and young children. The aim of this study was to describe for the first time the genetic variability of HRSV in Cameroonian patients living in Yaounde for three consecutive epidemic seasons. Methods HRSV-positive nasopharyngeal samples detected in children less than...

Assessment of variations in Indian Bubalus bubalis seminal plasma proteins during winter and summer seasons

 The Indian riverine buffaloes are more susceptible to variations in the environment. These variations affect seminal plasma proteins, which in turn affect fertility. This study was conducted to evaluate variations in the Indian Bubalus bubalis seminal plasma protein profile using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) during winter and summer seasons, and its relation wit...

Variation of respiratory syncytial virus and the relation with meteorological factors in different winter seasons.

BACKGROUND Respiratory syncytial virus (RSV) is the most important viral agent causing severe respiratory disease in infants and children. In temperate climates, RSV activity typically peaks during winter. We have described the seasonal variation in RSV activity and investigated which meteorological variables are related to RSV outbreaks for different time lags. METHODS Eleven laboratories in...
