Millions living with leprosy in spite of being curable

On January 26th The World Day of Leprosy, I saw a video on The Guardian global development news page by Maria Zupello  titled Leprosy in Brazil: Uncovering a hidden disease. Realizing that leprosy is still around was rather disturbing, especially because this is a curable disease and therefore there should be no such thing as living with leprosy in these times, but after doing some research it became apparent that is not the case.

WHO: Leprosy Statistics:

According to the World Health Organization's latest stats on leprosy in the world, there are still around 200,000 reported new cases of leprosy every year in the world. Also known as Hansen's Disease, leprosy is endemic in 91 countries around the world. The highest concentration of reported new cases (at the start of 2012) being in South East Asia (117,147). The majority of which are in India. The second highest incidence is in the Americas (34,801),  of these reported new cases the majority are from Brazil. But because of its long incubation period and the lack of tools to allow early detection leading to late diagnosis, the exact prevalence of Hansen's disease is not clear.

India:
Although the Indian Government declared it has eliminated leprosy in 2005. It has since then become clear that the claim was premature. Of the total leprosy cases in the world 55% are in India, and about 127,000 new cases were reported between 2010-2011. Besides lack of access to basic healthcare services, leprosy patients also suffer socioeconomic isolation as a result of the stigma and discrimination that still exists in India.

Brazil: 
Leprosy is more prevalent in Brazil than in any other country except India. More than 30,000 new cases are diagnosed each year. Despite economic development, expansion of public healthcare, and efforts of the leprosy control program in the past 30 years, this disease has not been eliminated, and new cases are still being detected. The leprosy control program in Brazil distributes free drugs as part of the World Health Organization multidrug regimen for treatment of leprosy. Unfortunately health care services are not available in rural parts of the country. The amazon region of Brazil where leprosy has been endemic for more than a century is almost deprived of such health services.
Leprosy is particularly prevalent among the poorest and most marginalised communities due to their lack of access to healthcare, poor sanitation and congested living spaces. - See more at: http://www.tlmindia.org/index.php/about-leprosy/facts#sthash.zlOMnaBW.dpuf

Government statistics under estimate the extent of leprosy according to research organisations, NGOs and some medical personnel who argue that leprosy cases are on the rise - See more at: http://www.tlmindia.org/index.php/about-leprosy/facts#sthash.zlOMnaBW.dpuf

To understand why the stigmatization, socioeconomic isolation, discrimination leading to leprosy communities in countries like India and Brazil is so wrong, here are some basic facts about Leprosy( Hansen's Disease);

What is Leprosy?

Leprosy is a chronic bacterial disease caused by Mycobacterium leprae and Mycobacterium lepromatosis. This infection primarily affects the skin, peripheral nerves and upper airway. It is well known that leprosy is not spread through casual contact. 

About 95% of human beings are naturally immune making leprosy the 'least contagious communicable disease'. The World Health Organization suggests that it is transmitted through moisture from the nose and mouth during frequent and close contact with an untreated leprosy-affected person. It might also happen if you are exposed to other nasal fluids (also known as secretions). Droplets and other secretions can contain the bacteria that cause Hansen’s disease. If you breathe these in, you can become sick with the disease.

According to the CDC,  as incubation period of the bacteria is long , it may take up to 2-10 years for signs and symptoms to appear. The disease mainly affects the skin, nerves and the mucous membranes. Common signs and symptoms include; disfiguring skin sores, lumps, or bumps that do not go away after several weeks or months. The skin sores are pale-colored. Nerve damage can lead to loss of feeling in arms and legs and muscle weakness. Without treatment, leprosy can permanently damage your skin, nerves, arms, legs, feet, and eyes.

Treatment of Leprosy

Leprosy can be cured. In the last two decades, more than 14 million people with leprosy have been cured. The World Health Organization provides free treatment for all people with leprosy.
Treatment depends on the type of leprosy that you have. It is treated with a combination of antibiotics. The treatment may last anywhere from 6 months to 2 years. People with severe leprosy may need to take antibiotics longer. Antibiotics cannot treat the nerve damage.
Anti-inflammatory drugs are used to control swelling related to leprosy. This may include steroids, such as prednisone.
Patients with leprosy may also be given thalidomide, a potent medication that suppresses the body's immune system. It helps treat leprosy skin nodules. Thalidomide is known to cause severe, life-threatening birth defects and should never be taken by pregnant women.

According to the WHO 'Access to information, diagnosis and treatment with multidrug therapy (MDT) remain key elements in the strategy to eliminate the disease as a public health problem, defined as reaching a prevalence of less than 1 leprosy case per 10,000 population. Only a couple of endemic countries have still to achieve this goal at the national level; most are now applying the same elimination strategy at regional, district and sub-district levels. MDT treatment has been made available by WHO free of charge to all patients worldwide since 1995, and provides a simple yet highly effective cure for all types of leprosy.
Most countries that were previously highly endemic for leprosy have achieved elimination at the national level and are intensifying their efforts at regional and district levels.'

Information campaigns about leprosy in high risk areas are crucial so that patients and their families, who were historically ostracized from their communities, are encouraged to come forward and receive treatment. The most effective way of preventing disabilities in leprosy, as well as preventing further transmission of the disease, lies in early diagnosis and treatment with MDT. (WHO)
