Updated Jan 11, 2021 | 11:52 IST For the first time, researchers have identified how viruses such as the poliovirus, and the common cold virus are able to package up their genetic code, allowing them to infect cells.

Researchers unravel the process that makes viruses infectious Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus package up their genetic code, allowing them to infect cells. The findings, published today (Friday, 8 January) in the journal PLOS Pathogens by a team from the Universities of Leeds and York, open up the possibility that drugs or anti-viral agents can be developed that would stop such infections. Once a cell is infected, a virus needs to spread its genetic material to other cells. This is a complex process involving the creation of what are known as virions - newly-formed infectious copies of the virus. Each virion is a protein shell containing a complete copy of the virus s genetic code. The virions can then infect other cells and cause disease. ....
