Among the diseases to have achieved a medical end is smallpox. But it is exceptional for several reasons: There is an effective vaccine, which gives lifelong protection; the virus, Variola major, has no animal host, so eliminating the disease in humans meant total elimination; and its symptoms are so unusual that infection is obvious, allowing for effective quarantines and contact tracing.
But while it still raged, smallpox was horrific. Epidemic after epidemic swept the world, for at least 3,000 years. Individuals infected with the virus developed a fever, then a rash that turned into pus-filled spots, which became encrusted and fell off, leaving scars. The disease killed three out of 10 of its victims, often after immense suffering.
In 1633, an epidemic among Native Americans “disrupted all the native communities in the northeast and certainly facilitated English settlement in Massachusetts,” said Harvard historian Dr. David S. Jones. William Bradford, leader of the Plymouth colony, wrote an account of the disease in Native Americans, saying the broken pustules would effectively glue a patient’s skin to the mat he lay on, only to be torn off. Bradford wrote: “When they turn them, a whole side will flay off at once as it were, and they will be all of a gore blood, most fearful to behold.”
The last person to contract smallpox naturally was Ali Maow Maalin, a hospital cook in Somalia, in 1977. He recovered, only to die of malaria in 2013.
Forgotten influenzas
The 1918 flu is held up today as the example of the ravages of a pandemic and the value of quarantines and social distancing. Before it ended, the flu killed 50 million to 100 million people worldwide. It preyed on young to middle-aged adults — orphaning children, depriving families of breadwinners, killing troops in the midst of World War I.
In the autumn of 1918, Victor Vaughan, a prominent doctor, was dispatched to Camp Devens near Boston to report on a flu that was raging there. He saw “hundreds of stalwart young men in the uniform of their country, coming into the wards of the hospital in groups of ten or more,” he wrote. “They are placed on the cots until every bed is full, yet others crowd in. Their faces soon wear a bluish cast, a distressing cough brings up blood stained sputum. In the morning the dead bodies are stacked up in the morgue like cord wood.”
The virus, he wrote, “demonstrated the inferiority of human inventions in the destruction of human life.”
Great to hear that small pox is earadicated from this world. Thanks for this great news.
