Answer:
Wild poliovirus is spread through faeces and saliva. It is primarily transmitted through faecal–oral spread and is an important consideration where sanitation is poor. 'Live' oral polio vaccine (OPV) virus can be shed in the faeces for 6 weeks and may lead to infection in unvaccinated contacts.
