Eradication of a disease is a very difficult and multi-factorial, multi-faceted
question. The prevalence of COVID-19 in the regions around the country, the intensity
of the population’s relationship with other countries, age distribution, and other
demographic factors affect the magnitude of the impact of the disease on a population.
In addition, the virulence of the virus, the immunity level of the population, measures
taken for immunization, availability of necessary drugs, the capacity of the health
sector to mitigate the pandemic will affect the damage on the society as a whole. The
tests applied to identify the cases, filing, and surveillance are effective factors in the
response of the state's health organization to this disease.
