TRACHOMA

Disease: Trachoma affects about 84 million people worldwide, mostly in developing countries and populations marked by poverty, crowded living conditions, and/or poor hygiene. Trachoma is an infectious disease caused by the microorganism Chlamydia trachomatis. The symptons may include a cloudy cornea, discharge from the eye, swelling of the lymph nodes just in front of the ears, swollen eyelids, and turned-in eyelashes. After years of repeated infection, the inside of the eyelid may be scarred so severely that the eyelid turns inward and the lashes rub on the eyeball, scarring the cornea (the front of the eye).
How it's spread: Trachoma is spread through direct contact with eye (also nose and throat) discharge from an infected person or through contact with infected items such as towels, handkerchiefs, clothes, fingers, etc. The disease can also be spread through transmission by eye-seeking flies.
Effects: If untreated, this condition leads to the formation of irreversible corneal opacities and blindness. At present, it is responsible for more than 3% of the world’s blindness. The socioeconomic effects are endless, with the disease increasing the population of disabled residents in communities who cannot work and must be taken care of, stretching already minimal resources.
Cure: Trachoma is easily treatable. Antibiotics can prevent long-term complications if began in the early stages of the infection. The antibiotics include erythromycin and doxycycline. Occasionally, eyelid surgery may be needed to prevent long-term scarring.

VITAMIN A DEFICIENCY

Condition: Vitamin A deficiency (VAD) is an issue in over half of all countries, especially countries in Southeast Asia and Africa. Pregnant women and children are primarily affected. The condition causes blindness and in many instances, death. Other results of Vitamin A deficiency include itchy dry skin, dry hair and a decreased resistance to infections.
Causes: Obviously, a lack of Vitamin A in one's diet is the primary cause of Vitamin A deficiency. The micronutrient is found in high quantities in foods that come from animals (liver, eggs, dairy products) and in many fresh fruits and vegetables. In many parts of the world, due to poverty or environmental issues, people have limited access to food at all, much less Vitamin A rich foods.
Effects: One of the tell-tale signs of Vitamin A deficiency is night blindness. This is because Vitamin A aides in the production of rhodopsin, an eye pigment responsible for seeing in low light
situations. If left untreated, Vitamin A deficiency can progress to complete blindness. In addition, in both children and pregnant women, Vitamin A deficiency increases susceptibility to infections and the body's ability to fight them. Therefore, people affected by this condition have very high mortality rates. In fact, it is estimated that up to 500,000 children go blind each year due to Vitamin A deficiency, and over half of those children die within a year of losing their sight.
Treatment: In order to be effective, there have to be both long and short term treatments for Vitamin A deficiency. First, for people already affected, Vitamin A supplements are necessary twice per year. Each dose costs about $0.02. Next, food fortification (adding Vitamin A to certain foods) has proved very effective. Finally, promoting dietary diversification is important. Encouraging people in rural areas to grow their own Vitamin A rich food is a great way to prevent Vitamin A deficiency in the long run. Many global organizations have
launched efforts against the condition and it is hoped to be eliminated by 2010.

GUINEA WORM


Condition
: Guinea worm, also known as Dracunculiasis, is a crippling condition caused by a water-borne parasite. Between 1986 and 2008, the prevalence of the disease dropped from 3.5 million to 5,000. However, it continues to be endemic in 6 African countries. Guinea worm is one of the oldest recorded diseases, and it has been found in calcified Egyptian mummies.
Causes: The primary cause of guinea worm is a lack of clean water. Guinea worm larvae are present in contaminated water sources, and are eaten by a water flea. When a person drinks the water, they also ingest the flea and the larvae. Once inside the stomach, the flea is consumed by stomach acid, but the larvae remains and migrates throughout the body tissues. After approximately one year, the guinea worm is fully mature, and it emerges through a painful blister in one of the lower extremities. People often submerge the affected extremity in a water source to relieve the pain, and when they do so, the mature worm releases thousands of larvae into the water source, thus continuing the cycle.
Effects: As stated before, when the guinea worm begins to emerge from the skin, it is extremely painful for the victim. They often experience fever and intense burning and itching. Due to the pain, people are unable to work or attend school for up to three months. In agricultural areas, this means food shortages, lower earnings, and detrimental effects on local economies.
Treatment: Once a person is infected with guinea worm, treatment is gruesome. As the worm, which is several centimeters long and has the circumference of a spaghetti noodle, emerges from the body, a health care professional must pull it a few millimeters each day until it is freed from the body. This painful process can take several weeks, during which time victims are often unable to walk. Obviously, prevention is key, and behavioral changes are crucial. Prevention
efforts include improved water supply, the use of water filters, and community education. There are numerous international campaigns to prevent guinea worm, and it is hoped to be completely eradicated in the very near future.

ELEPHANTIASIS

Condition: Elephantiasis, or lymphatic filariasis, is a disfiguring condition caused by microscopic, parasitic worms. Currently, there are 120 million people infected, and one-third of those people are seriously incapacitated by it. It is most prevalent in Africa and Southeast Asia, especially in India. It is more common in men than in women, and in endemic communities, up to 50% of men and 10% of women may be affected.
Causes: The parasites are spread from human to human by mosquito bites. It is very common in poor, densely populated areas. Once inside the body, the worms and their offspring clog the lymphatic vessels causing an immune response and extreme swelling in the victim.
Effects: The effects of elephantiasis are extreme. The most visible effect is acute swelling primarily in the lower extremities, especially the legs, feet, and genitals. Swelling can also occur in the torso, arms, breasts, and even the face. In addition to the visible swelling, elephantiasis can damage internal organs as well. In many communities, there is a social stigma against those infected, and they often suffer from psychological and emotional issues.
Treatment: The treatment for elephantiasis is not clearly defined. However, a combination of drugs, which varies depending on the region, along with rigorous cleaning of the affected area has proved effective. Two drug companies, SmithKline Beecham and Merck, have collaborated with the World Health Organization, and have agreed to donate doses of their respective drugs, albendazole and ivermectin, until the disease is eradicated. Several other organizations have also joined the fight, and it is hoped that the disease will be completely eradicated by 2020.
