Polio research

Research by Melnick found that the most common way that polio was spread was by fecal contamination, usually by soiled hands, and that the poliovirus

Poliovirus, the causative agent of poliomyelitis, is a human enterovirus and member of the family of Picornaviridae.Poliovirus is composed of an RNA genome and a protein capsid. The genome is a single-stranded positive-sense RNA genome that is about 7500 nucleotides long. The viral particle is...

, were also found in sewage, leading to improved purification standards. Higher levels of the polio virus were found in sewage during the summer, at the same time of year that the outbreaks of the disease were at their most severe, which John R. Paul observed "spoke loudly in favor of the idea that polio viruses circulate widely in the population and environment only during epidemic seasons". Together with Dr. Dorothy Horstmann, Melnick published the results of a study that showed that polio could be transmitted by flies, though they were not the primary vector for the disease. He was among the first to discover that the polio virus belonged to a larger class now known as the enterovirus

Serologic studies have distinguished 66 human enterovirus serotypes on the basis of antibody neutralization tests. Additional antigenic variants have been defined within several of the serotypes on the...
