The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and cause paralysis.

28 Νοε 2023 · Poliovirus is highly contagious and infected individuals shed virus in the faeces and from oral secretions, thus the mode of transmission is person-to-person, both via the faecal-oral and the oral-oral routes.
We also discuss the evidence of waning of host immunity to poliovirus transmission, the relationship between the concentration of poliovirus excreted and infectiousness, the importance of different transmission routes, and the differences in transmissibility between OPV and WPV.
Modes of Transmission. The spread of the disease is through the fecal-oral route. The dissemination of the virus in the feces is the reason of it being a highly communicable disease. Maximum excretion of the virus is seen in 2 to 3 days prior and 1 week after appearance of symptoms.
Our analyses allow us to dissect three axes of polio epidemiology: (i) geographical and seasonal variation in transmission, (ii) the role of demography in determining incidence, and (iii) the mode by which polio persists.
22 Οκτ 2024 · Polio is a highly infectious disease caused by a virus. It invades the nervous system and can cause total paralysis in a matter of hours. The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (for example, contaminated water or food) and multiplies in the intestine.
What is polio and how does it spread? It can be a serious infection, caused by a virus which spreads easily through contact with the faeces (poo) of an infected person or less commonly through...
