Polio is a viral infection that in endemic areas is transmitted largely

Question Polio is a viral infection that in endemic areas is transmitted largelyby the faeco-oral route (that is, passing out of infected hosts via their faeces, contaminating water (or food), and entering an uninfected host through their mouth when they ingest that food or water). It is of low pathogenicity with a clinical to subclinical case ratio of approximately 1 to 20. The pathogenicity does increase with age however. Infection is followed by lifelong, strain specific immunity.In the absence of concurrent immunisation, how will improved environmental hygiene and sanitation influence: -The age of cases of paralytic polio in an endemic area?
