Gamaliel's Principle
Epidemiologically, whatever it is may not kill every snake. Or the disease state may not have a precise (identical) temporally defined incubation period, latency period, or morbidity.
For example, in mammals, the echoviruses and enteroviruses. They may cause a disease state in some individuals, while some individuals remain asymptomatic, or never get sick. They may kill some individuals, while some never get more than the sniffles or a head cold. Infants and the elderly, for example, may be more susceptible than healthy adolescents and adults.
Note: general diagnosis relies on pre-acute and post-acute antibody titers. And only some certain few subtypes or serotypes of these very small, spring-time viruses are even tested for (in a reference lab type setting).
