Charting the Disappearance of Smallpox from the 1700s to 1900s: A closer look at the annihilation of one of history's deadliest diseases
Global Success: Smallpox Eradication
Smallpox, the only human disease to be eradicated, was a significant cause of mortality for centuries, rivaling the devastation of the bubonic plague. However, through groundbreaking advances in immunology and international cooperation, the disease was successfully eradicated, marking a major achievement in global health history.
The eradication of smallpox was a monumental success, as it was a disease that was endemic across all continents and caused massive fatalities worldwide. Initially, smallpox vaccines were developed and administered locally, with the first successful vaccine created in 1796 by Edward Jenner.
A Deadly Virus: Understanding Smallpox
Smallpox is an infectious disease caused by the variola virus and was primarily transmitted through air droplets from infected individuals. Symptoms included pustules covering the patient's entire body, fever, headache, and a rash that occurred 10-14 days after infection. Children were particularly vulnerable, with the disease claiming many young lives.
Despite the lack of treatment, the smallpox virus eventually met its demise thanks to the WHO's Intensified Smallpox Eradication Program, launched in 1966. The program employed mass vaccination campaigns, followed by surveillance and containment strategies to prevent further outbreaks.
The Smallpox Eradication Program: A Global Effort
The eradication program relied on global collaboration to pool resources and expertise, as well as the development of technological innovations such as stabilized freeze-dried vaccines, bifurcated needles, and improved storage methods. By 1977, the last naturally occurring case of smallpox was reported, marking the beginning of the end of this devastating disease.
On May 8, 1980, the World Health Assembly officially certified the global elimination of smallpox, the first-ever eradication of a disease in human history. Remaining samples of the variola viruses are now stored securely in two facilities: the State Research Center of Virology and Biotechnology in Moscow and the Centers for Disease Control and Prevention in Atlanta.
A Lasting Impact: Lessons Learned from Smallpox Eradication
Smallpox eradication demonstrated the potential for coordinated global action to tackle deadly infectious diseases. The vaccine used in the eradication program is still effective today and remains crucial in preventing smallpox outbreaks in vulnerable populations. Additionally, public health infrastructure was strengthened in many countries as a result of the eradication program, furthering the global fight against infection.
The eradication of smallpox serves as an inspiration for future efforts in disease control and prevention, highlighting the power of science, technology, international collaboration, and public health commitment in overcoming seemingly insurmountable challenges.

In the face of smallpox, a disease that once ravaged populations across all continents, causing massive fatalities and particularly affecting children, the discovery and widespread administration of the smallpox vaccine set the stage for its eventual eradication. The eradication program, launched in 1966 and relying on global collaboration, technological innovations, and mass vaccination campaigns, marked a significant leap towards addressing chronic diseases and medical-conditions, proving the potential impact of health-and-wellness initiatives on a global scale.
