Q:Information: - Johanna '' Anne '' Mansfield Sullivan Macy ( April 14 , 1866 -- October 20 , 1936 ) , better known as Anne Sullivan , was an American teacher , best known for being the instructor and lifelong companion of Helen Keller . She contracted trachoma , a highly infectious eye infection , when she was eight to ten years old which left her blind and without reading or writing skills . She received her education as a student of the Perkins School for the Blind where upon graduation she became a teacher to Keller when she was 20 . - Conjunctivitis, also known as pink eye, is inflammation of the outermost layer of the white part of the eye and the inner surface of the eyelid. It makes the eye appear pink or reddish. There may also be pain, burning, scratchiness, or itchiness. The affected eye may have increased tears or be "stuck shut" in the morning. Swelling of the white part of the eye may also occur. Itching of the eye is more common in cases due to allergies. Conjunctivitis can affect one or both eyes. The most common infectious causes are viral followed by bacterial. The viral infection may occur along with other symptoms of a common cold. Viral and bacterial cases are easily spread between people. Allergies to pollen or animal hair is also a common cause. Diagnosis is often based on signs and symptoms. Occasionally a sample of the discharge is sent for culture. Prevention is partly by handwashing. Treatment depends on the underlying cause. In the majority of viral cases, there is no specific treatment. Most cases due to a bacterial infection will also resolve without treatment; however, antibiotics can shorten the illness. Those who wear contact lens and those with either gonorrhea or chlamydia as the cause should be treated. Allergic cases can be treated with antihistamine or mast cell inhibitor drops. About 3 to 6 million people get conjunctivitis each year in the United States. In adults viral causes are more common, while in children bacterial causes are more common. Typically people get better in one or two weeks. If there is visual loss, significant pain, sensitivity to light, signs of herpes, or a person is not improving after a week, further diagnosis and treatment may be required. Conjunctivitis in a newborn, known as neonatal conjunctivitis, may also require specific treatment. - Neglected tropical diseases (NTDs) are a diverse group of tropical infections which are especially common in low-income populations in developing regions of Africa, Asia, and the Americas. They are caused by a variety of pathogens such as viruses, bacteria, protozoa and helminths. These diseases are contrasted with the big three diseases (HIV/AIDS, tuberculosis, and malaria), which generally receive greater treatment and research funding. In sub-Saharan Africa, the impact of these diseases as a group is comparable to malaria and tuberculosis. NTD co-infection can also make HIV/AIDS and tuberculosis more deadly. - Trachoma, also called granular conjunctivitis, Egyptian ophthalmia, and blinding trachoma, is an infectious disease caused by bacterium "Chlamydia trachomatis". The infection causes a roughening of the inner surface of the eyelids. This roughening can lead to pain in the eyes, breakdown of the outer surface or cornea of the eyes, and eventual blindness. Untreated, repeated trachoma infections can result in a form of permanent blindness when the eyelids turn inward. The bacteria that cause the disease can be spread by both direct and indirect contact with an affected person's eyes or nose. Indirect contact includes through clothing or flies that have come into contact with an affected person's eyes or nose. Children spread the disease more often than adults. Poor sanitation, crowded living conditions, and not enough clean water and toilets also increase spread. Efforts to prevent the disease include improving access to clean water and decreasing the number of people infected by treatment with antibiotics. This may include treating, all at once, whole groups of people in whom the disease is known to be common. Washing by itself is not enough to prevent disease but may be useful with other measures. Treatment options include oral azithromycin and topical tetracycline. Azithromycin is preferred because it can be used as a single oral dose. After scarring of the eyelid has occurred, surgery may be required to correct the position of the eyelashes and prevent blindness. Globally, about 80 million people have an active infection. In some areas infections may be present in as many as 6090% of children and it more commonly affects women than men likely due to their closer contact with children. The disease is the cause of decreased vision in 2.2 million people of whom 1.2 million are completely blind. It commonly occurs in 53 countries of Africa, Asia, Central and South America with about 230 million people at risk. It results in US$8 billion of economic losses a year. It belongs to a group of diseases known as...
