Cause Of Hepatitis A Virulence Pinpointed

NIH/National Institute Of Allergy And Infectious Diseases
Summary:
Researchers at the National Institute of Allergy and Infectious Diseases (NIAID) have located two genes that give hepatitis A virus (HAV) its virulent properties. The team, led by Suzanne Emerson, Ph.D., also has discovered that deliberately weakened HAV can quickly revert to its naturally occurring, infection-causing form. To be published in the September 1 issue of Journal of Virology, and appearing online this week, these findings indicate that making an improved vaccine for HAV will be a very difficult task.
