This article presents a collection of studies and articles that challenge the idea that polio is a contagious disease. It suggests that the prevailing view of polio as contagious may not be accurate.
Key points that argue against polio being contagious include:
Early descriptions of polio came from diverse areas like England, Italy, India, and the U.S.
Many observed that polio did not seem to spread like a contagious disease. For example, in a 1905 polio epidemic, cases often occurred far apart with no obvious connections.
Epidemics did not always follow patterns of contagion, and cases were often scattered, making it difficult to trace contact between cases.
Polio often did not spread in families. It was unusual to find more than one case in a family or household.
Many studies failed to prove contagion.
Attempts to transmit the disease to laboratory animals, like monkeys, were unsuccessful.
Polio did not spread in hospitals or among medical staff. Even when in close contact with patients, nurses and doctors rarely contracted the disease.
Polio has a seasonal pattern with most cases occurring in the late summer and early autumn.
The disease is more prevalent in rural areas than in densely populated cities.
These points are presented as reasons to question the theory that polio is spread through direct human contact. The source material argues that the non-contagious nature of polio is supported by observations that contradict the idea of human-to-human transmission.
