Smallpox Treatment: A Historical Look at Battling One of the Deadliest Diseases

For centuries, smallpox devastated populations around the world. Caused by the variola virus, smallpox resulted in severe illness and death for 30% of those infected. With no effective treatments available, communities lived in constant fear of smallpox outbreaks. Thankfully, through vaccination efforts led by pioneering scientists like Edward Jenner and coordinated global campaigns by the World Health Organization, smallpox was declared eradicated in 1980. However, understanding the long struggle to treat smallpox can help inform modern efforts to battle infectious diseases. This article provides a historical overview of attempts to treat smallpox from ancient times to its ultimate elimination.

Early Treatments and Misguided Approaches

Some of the earliest recorded mentions of Smallpox Treatment back to ancient India and China from around 1000 BC. However, no truly effective smallpox treatments were available. Many civilizations turned to folk remedies and superstitions that provided no medical benefit. For example, some early Chinese and Indian texts recommended treatments like swallowing powdered smallpox scabs or inhaling the smoke of burning cow dung. Later in Europe during the Middle Ages, treatments focused on bleeding, purging, and bathing patients in cold water or vinegar in misguided attempts to “shock” the illness from the body. These practices likely caused further harm and did little toimpact disease progression.

Without understanding the germ theory of disease, physicians were limited in their ability to treat smallpox directly. Frustrated by the lack of progress and huge toll of the disease, some doctors experimented with inoculation techniques introduced from Asia. For instance, methods involving inserting smallpox infected material underneath the skin attempted to purposefully induce a mild infection to develop immunity. However, these early inoculation attempts also carried significant risks.

Key Advances in Vaccination

A major breakthrough occurred in 1796 when English physician Edward Jenner discovered vaccination using cowpox. Jenner had observed that milkmaids who had previously contracted cowpox, a related virus, seemed immune to smallpox. Through controlled experiments, he demonstrated that deliberately infecting a person with cowpox could protect them from subsequent smallpox infection. Jenner’s pioneering work established vaccination as a safe and effective way to prevent smallpox without risking a deadly case of the disease.

As vaccination became more widely adopted throughout the 1800s, new methods improved its safety and effectiveness. For example, techniques emerged for producing vaccinia virus outside the body using calf lymph. This made it easier to manufacture vaccine doses on a larger scale. Additionally, use of bifurcated needles and multiple prong scarification methods reduced adverse reaction rates compared to early techniques involving direct inoculation. International vaccination programs began ramping up in the 20th century and played a pivotal role in bringing smallpox under control.

Treatment of Active Smallpox Infections

Even as vaccination efforts took hold globally, physicians continued attempting to treat active smallpox cases to minimize suffering and curb transmission. During major outbreaks, isolation hospitals were established to separate infected individuals and limit community spread. Treatments focused on supportive care like maintaining hydration, controlling fever, and preventing secondary infections.

In 1910, US doctor William C. Osler published a book called “The Principles and Practice of Medicine” that provided guidance to physicians treating smallpox patients. Some recommendations included sponging febrile patients with cool water, applying calamine lotion to reduce itching, and administering analgesics for pain. As antibiotic therapies emerged mid-century, drugs like penicillin could effectively combat secondary bacterial infections associated with smallpox. Usage of alpha-interferon treatments in the 1960s showed promise but required further research. However, overall mortality rates remained high without a cure for the variola virus itself.

Driving Smallpox to Extinction

The paradigm completely shifted by the latter half of the 20th century with the launch of intense global eradication efforts under WHO leadership. Countries stepped up national immunization programs, established disease surveillance networks, and rapidly contained any outbreaks that did occur using ring vaccination techniques. In 1967, WHO adopted systematic surveillance and containment protocols that proved hugely successful. By 1977, only two endemic nations remained – Ethiopia and Somalia. After an all-out push to track down the last remaining cases, WHO declared on May 8, 1980 that smallpox had been eliminated from the face of the earth, a momentous achievement in public health.

Through over two millennia, the devastating impact of smallpox drove civilizations to pursue many treatments – both evidence-based and misguided. A long learning process, culminating in Jenner’s vaccination discovery and the post-WWII eradication campaign, stamped out one of history’s worst plagues. While treatments never cured active smallpox infections, mass immunization enabled humanity to defeat this contagion altogether. The smallpox story shows that coordinated global health efforts employing vaccination can overcome even the most pervasive pathogens. Continued immunization vigilance remains crucial should smallpox virus stocks be potentially released from labs. The lessons of tackling smallpox continue guiding modern strategies to control infectious diseases worldwide.
