Communicability

Poliovirus is highly infectious, with seroconversion rates among susceptible household contacts of children nearly 100%, and greater than 90% among susceptible household contacts of adults. Persons infected with poliovirus are most infectious in the days immediately before and after the onset of symptoms, but poliovirus may remain present in the stool for up to 6 weeks.

A small number of pets worldwide, including cats and dogs, have been reported to be infected with the virus that causes COVID-19, mostly after close contact with people with COVID-19.

Based on the available information to date, the risk of animals spreading COVID-19 to people is considered to be low. At this time, there is no evidence that animals play a significant role in spreading SARS-CoV-2, the virus that causes COVID-19, to people.

I don't think we can wipe it out with the present level of technology.

We almost wiped out polio except that because of the CIA's fake vaccination campaign, people in Afghanistan and Pakistan don't trust our health care workers any more.
