New research findings point toward a class of compounds that could be effective in combating infections caused by enterovirus D68, which has stricken children with serious respiratory infections and might be associated with polio-like symptoms in the United States and elsewhere.

The researchers have used a technique called X-ray crystallography to learn the precise structure of the original strain of EV-D68 on its own and when bound to an anti-viral compound called “pleconaril.” The ongoing research could lead to the development of drugs that inhibit infections caused by the most recent strains of the virus.
