Question

Vaccinations and other public health measures had eliminated which disease globally by 1980? Select one: a. Ebola b. AIDS c. smallpox d. tuberculosis

2 Answer

  • the answer is c.smallpox because,Smallpox is the only disease that has been eradicated. During 1900-1904, an average of 48,164 cases and 1528 deaths caused by both the severe (variola major) and milder (variola minor) forms of smallpox were reported each year in the United States (1). The pattern in the decline of smallpox was sporadic. Outbreaks of variola major occurred periodically in the first quarter of the 1900s and then ceased abruptly in 1929. Outbreaks of variola minor declined in the 1940s, and the last case in the United States was reported in 1949. The eradication of smallpox in 1977 enabled the discontinuation of prevention and treatment efforts, including routine vaccination. As a result, in 1985 the United States recouped its investment in worldwide eradication every 26 days 
  • Smallpox has ended in the world today. However they keep the virus and it has alarmed people that it may be used in a chemical warfare. It is a very deadly disease
