The first case in United States was reported in New York City in 1999. Additional human cases are identified and deaths are reported daily. Here's what you need to know. WHO CONTRACTS WNV? WNV affects all races and men and women equally. The elderly, chronically ill, or immunosuppressed are more likely to become seriously ill or die from WNV. HOW IS WNV TRANSMITTED? -- WNV is carried from animal to animal by mosquito bites. Birds (especially crows) are most common victims, but WNV has infected horses and smaller animals as well. -- Birds, horses, humans, and other animals do not transmit disease. Mosquitoes do. Therefore, you will not get WNV if you handle animals who are infected. -- The more mosquito bites you have, more likely you are to become infected. This does *not* mean that you should run to doctor or your emergency room when a mosquito bites you. The likelihood that you have become infected is extremely small. HOW DO DOCTORS DIAGNOSE WNV? -- The signs and symptoms of WNV are fever, headache, loss of appetite, nausea and vomiting, muscle pain, eye pain, rash, and enlarged lymph glands. According to a recent article in Annals of Internal Medicine, incubaton period of WNV is from three to 14 days. -- WNV is dangerous when it develops into viral encephalitis or viral meningitis. Symptoms of viral encephalitis include confusion and a gradual loss of consciousness. Symptoms of viral meningitis include a stiff neck and neurological signs your doctor will recognize. -- Doctors diagnose WNV through a history and physical examination. They also order a blood test to detect antibody to WNV and or to find virus itself in blood. A case is considered to be "probable West Nile virus" when WNV antibody is identified and "confirmed West Nile virus" when virus itself is identified in blood. HOW DO DOCTORS TREAT WNV? Treatment for WNV is entirely supportive because there is no medication that specifically fights disease. As with any infection, be sure to drink plenty of fluids, get adequate rest, and take fever reducers, such as acetaminophen or aspirin, if you have symptoms of WNV. If you have symptoms and have been bitten by a mosquito recently, contact your physician.

August is Cataract Awareness Month, a reminder that cataract surgery can clear up your eyesight and improve your quality of life. According to American Academy of Ophthalmology, half of people between age 52 and 64, and almost everyone over age of 75, will have a cataract. Another way to look at it is that one in seven people in United States has a cataract. What Is a Cataract? A cataract is a clouding in lens of your eye. The onset of condition is slow and usually related to aging. Other causes are congenital birth defects, alcoholism, diabetes mellitus, eye injury, smoking, and long-time exposure to ultra-violet (UV) light. How Would I Know If I Had a Cataract? Visual problems are not apparent in beginning stages of a cataract. When they appear, you may have following symptoms: * A gradual blurring of your eyesight. * Poor distance vision. * A fading or yellowing of colors. * Double vision in affected eye. * A heightened sensitivity to light. * Trouble seeing well enough to drive at night. * Frequent need for changes in eyeglass prescriptions. How Are Cataracts Treated? At onset of cataracts, high magnification glasses may improve vision, but there are no medications or eye-drops that will help. Some people think that a cataract needs to be "ripe" before it can be removed, but this is not true. Instead, cataracts are removed when they interfere with normal activities of daily living. Ophthalmic surgeons remove cataracts under local anesthesia in outpatient area of a hospital or in special, stand-alone clinics. They take cataract out through a tiny slit at edge of sac that contains clouded lens. They usually use "phacoemulsification," a process that liquefies lens
