Human respiratory syncytial virus causes

Introduction

Overview

Overview

Influenza infection is caused by the influenza virus that belong to the family Orthomyxoviridae. Three types of influenza virus have been reported to cause clinical illness in humans: types A, B, and C. Influenza virus can be found in humans, as well as in poultry, pigs, and bats.

Taxonomy

Taxonomy

  • The scientific name of the virus is respiratory syncytial virus (hRSV)
    • Other names include human orthopneumovirus or respiratory syncytial virus (RSV)[1].
  • Member of the Pneumoviridae family and Orthopneumovirus genus.
  • Enveloped, negative sense, single stranded RNA virus[2].
  • Main subtypes are A and B. Most evidence suggests no difference in disease severity between both subtypes[3].
  • Lineage: Viruses > Riboviria > Orthornavirae > Negarnaviricota > Haploviricotina > Monjiviricetes > Mononegavirales (negative-sense genome single-stranded RNA viruses) > Pneumoviridae > Orthopneumovirus[1].
  • Natural hosts for hRSV are humans and chimpanzees[4].
  • Transmission directly through large droplets via nasal or oral secretions or indirectly through contact with contaminated surfaces[5][6].
