Relationship Between Shell Disorder and Modes of Transmission. The level of disorder (PID) rises as the fecal-oral component decreases. It should be noted that HeV is known to spread by contact with bodily fluid and therefore has a higher fecal-oral component. Depending of the strain, NiV can spread via respiratory and fecal-oral routes including close contacts with bodily fluids. MeV and HIV are spread mainly by respiratory and sexual modes respectively. For comparative purposes, only maximal PIDs found for a virus and protein are used.
