World Leprosy Day

Buổi tối an lành (do bây giờ là buổi tối)

World Leprosy Day, which occurs annually on the last Sunday of January, seeks to raise awareness about a disease that many mistakenly think has vanished, particularly in developed nations. Known as Hansen’s disease, leprosy is an infectious illness caused by a unique type of bacteria that affects the human body’s nervous system, primarily impacting the hands, feet, and face. This disease is believed to spread through prolonged exposure to the bacteria responsible for it. The observance of this day is not only about educating the public but also about highlighting the plight of those living with the disease.

The history of World Leprosy Day dates back to a time when leprosy was a significant concern. It is a chronic bacterial infection that can cause permanent damage to nerves, the respiratory tract, skin, and eyes. Those affected may experience a loss of sensation in the impacted areas, which often leads to overlooked injuries and, tragically, the loss of limbs. Symptoms can also include muscle weakness and vision problems.

Hansen’s disease was named after the Norwegian physician Gerhard Henrik Armauer Hansen, who was pivotal in identifying the bacteria that causes leprosy. To promote awareness about this disease and its socio-economic impacts, French philanthropist Raoul Follereau founded World Leprosy Day in 1954. In India, this day is marked on January 30, coinciding with the death anniversary of Mahatma Gandhi, honoring his unwavering compassion for those affected by leprosy. Although the disease is now easily treatable and infrequent in developed countries like the U.S., it is still burdened by stigma, particularly in countries such as India, Brazil, and Indonesia, where the highest case numbers are reported. Individuals infected with leprosy often face discrimination and social exclusion, which restricts their access to medical care, treatment, and basic human rights. The global community seems to be conveniently overlooking this issue, as leprosy primarily affects marginalized populations. World Leprosy Day serves as a reminder to increase awareness and encourage individuals to seek treatment, ensuring they can lead lives filled with dignity.

Importance of World Leprosy Day:
- To combat social discrimination: It is crucial to eliminate the social stigma surrounding leprosy, allowing patients to live with dignity. World Leprosy Day provides a vital platform to foster an inclusive society that treats affected individuals with respect.
