The Deadliest Diseases of Every Century: A Historical Look
In the past, diseases have wiped out entire communities, devastated countries, and even changed the course of history. While the world has made significant progress in eradicating certain diseases, we are still susceptible to new ones that continually emerge.

The good news is that smallpox was eradicated in 1980 after a significant global vaccination campaign.
The 2nd Century: Antonine Plague

Conclusion
History has shown us that diseases can have a significant impact on global health and society. The development of vaccines, antibiotics, and public health measures has significantly reduced the impact of disease, but we must remain vigilant against emerging diseases and maintain our commitment to public health. With continued research, prevention, and treatment, we can better protect ourselves and future generations from the deadliest diseases.
