  • HAV is primarily transmitted through the fecal-oral route, meaning it's passed along when people come into contact with the feces of an individual who has an HAV infection or consume food or water contaminated with the virus. (healthline.com)
  • For example, though most children under 6 years old who contract an HAV infection are asymptomatic, they can still transfer the virus to others. (healthline.com)

  • Observing the appearance of DNA in a virus particle is not something that can be done in a snap. (lu.se)
  • However, with the help of the synchrotron research facility NIST in Maryland, USA, and thanks to a special grant from the Swedish Research Council, we were ultimately able to use neutron light to image the structure of phage virus DNA and its density inside the capsid and see how these changed at different temperatures," explained Alex Evilevitch.
