Molecular epidemiology and host genetics of norovirus and rotavirus infections in Portuguese elderly living in aged care homes

  • Autores: Piedade J, Nordgren J, Esteves F, Esteves A, Teodósio R, Svensson L, Istrate C
  • Ano de Publicação: 2019
  • Journal: Journal of Medical Virology

Norovirus (NoV) and rotavirus group A (RVA) are major agents of acute gastroenteritis worldwide. This study aimed to investigate their epidemiological profile in Portuguese elderly living in long-term care facilities and to assess the host genetic factors mediating infection susceptibility. From November 2013 to June 2015, 636 faecal specimens from 169 elderly, mainly asymptomatic, living […]

  • Link: https://www.ncbi.nlm.nih.gov/pubmed/29534772%20

Norovirus (NoV) is a major cause of acute gastroenteritis (AGE). In this study, we investigated the genetic diversity of NoV strains identified in children under 5 years of age with AGE in four provinces of Angola. Faecal samples from 343 children were screened for NoV by an in house real-time PCR assay and genotyping was […]

Molecular epidemiology of rotavirus in four provinces of Angola before vaccine introduction

  • Autores: Dimbu R, Esteves A, Fortes F, Istrate C, Mendes C, Nordgren J, Pereira J, Saraiva N
  • Ano de Publicação: 2016
  • Journal: Journal of Medical Virology
  • Link: http://onlinelibrary.wiley.com/doi/10.1002/jmv.24510/epdf

Angola is a sub-Saharan country in southern Africa highly affected by diarrhoeal disease with limited epidemiological data regarding etiologic agents. This study was performed during 2012-2013, prior to rotavirus vaccine introduction, with the objective to detect and characterize the rotavirus strains circulating in four provinces of the country: Huambo, Luanda, Zaire, and Cabinda. A high […]

The burden of rotavirus infections greatly affects the low-income African countries. In the absence of epidemiological data on pediatric diarrhea in São Tomé and Príncipe (STP), a study was conducted from August to December 2011.
