Explain the most likely reason why smallpox was successfully eradicated
but Naegleria probably never will be.
The symptoms of smallpox are easier to identify than the symptoms of Naegleira, so some carriers of Naegleria are not accurately diagnosed. This can lead to asymptomatic carriers present within the population of susceptible individuals, spreading the pathogen.
Since there are very few cases of naegleria each year, there is little financial incentive to push health organizations to eradicate the illness through worldwide vaccination.
Smallpox was ONLY found in humans; Naegleria is found in an environmental reservoir. We cannot reasonably eliminate Naegleria in all of the fresh water reservoirs that exist.
Smallpox was far easier to vaccine the world population against than Naegleria is due to the lower number of injections required-it becomes a compliance issue.
