Dracunculiasis
Dracunculiasisuroosa farooq Dracunculiasis, also known as guinea worm disease, is caused by the nematode Dracunculus medinensis. It is transmitted when people drink water contaminated with water fleas infected with Dracunculus medinensis larvae. The larvae mature and emerge slowly from blisters on the skin after about a year, causing intense pain. Prevention focuses on filtering drinking water and preventing people with emerging worms from contaminating water sources. India launched a national eradication program in 1984 and was certified guinea worm free in 2000 after three years of zero reported cases. Surveillance continues to ensure guinea worm disease does not reemerge.

Yaws 
Yaws Shweta Kaushik YAWS
Yaws is a chronic infection that affects mainly the skin, bone and cartilage.
The disease occurs mainly in poor communities in warm, humid, tropical areas of Africa, Asia and Latin America.
The causative organism is a bacterium called Treponema pertenue, a subspecies of Treponema pallidum that causes venereal syphilis. However, yaws is a non-venereal infection.
About 75% of people affected are children under 15 years of age (peak incidence occurs in children aged 6-10 years); males and females are affected and no race is exempt.
Yaws is transmitted mainly through direct skin contact with an infected person.
A single skin lesion develops at the point of entry of the bacterium after 2–4 weeks. Without treatment, multiple lesions appear all over the body.
Overcrowding, poor personal hygiene and poor sanitation facilitate the spread of the disease.
The disease is rarely fatal; however, it can lead to chronic disfigurement and disability. Yaws can be treated with a single dose of a cheap and effective antibiotic: Benzathine Penicillin injection cures the disease.
