Dengue (pronounced DENgee) fever is a painful, debilitating mosquito-borne disease caused by any one of four closely related dengue viruses. These viruses are related to the viruses that cause West Nile infection and yellow fever.
An estimated 390 million dengue infections occur worldwide each year, with about 96 million resulting in illness. Most cases occur in tropical areas of the world, with the greatest risk occurring in: Most cases in the United States occur in people who contracted the infection while traveling abroad. But the risk is increasing for people living along the Texas-Mexico border and in other parts of the southern United States. In 2009, an outbreak of dengue fever was identified in Key West, Fla.
Dengue fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus. The mosquito becomes infected when it bites a person with dengue virus in their blood. It cant be spread directly from one person to another person.
Symptoms, which usually begin four to six days after infection and last for up to 10 days, may include Sometimes, symptoms are mild and can be mistaken for those of the flu or another viral infection. Younger children and people who have never had the infection before tend to have milder cases than older children and adults. However, serious problems can develop. These include dengue hemorrhagic fever, a rare complication characterized by high fever, damage to lymph and blood vessels, bleeding from the nose and gums, enlargement of the liver, and failure of the circulatory system. The symptoms may progress to massive bleeding, shock, and death. This is called dengue shock syndrome (DSS).

Psoriasis is a chronic skin disorder that causes scaling and inflammation. Psoriasis may develop as a result of an abnormality in the body's immune system. The immune system normally fights infection and allergic reactions. Psoriasis probably has a genetic component. Nearly half of patients have family members with psoriasis. Certain medications may trigger psoriasis. Other medications seem to make psoriasis worse in people who have the disease.
Psoriasis causes skin scaling and inflammation. It may or may not cause itching. There are several types of psoriasis: 1. Plaque psoriasis. In plaque psoriasis, there are rounded or oval patches (plaques) of affected skin. These are usually red and covered with a thick silvery scale. The plaques often occur on the elbows, knees, scalp or near the buttocks. They may also appear on the trunk, arms and legs. 2. Inverse psoriasis. Inverse psoriasis is a plaque type of psoriasis that tends to affe...

Topical treatments. These are treatments applied directly to the skin. 1. Daily skin care with emollients for lubrication. These include petroleum jelly or unscented moisturizers. 2.

In most cases, diagnosis of psoriasis is fairly straightforward. 1. Physical exam and medical history. Your doctor usually can diagnose psoriasis by taking your medical history and examining your skin, scalp and nails. 2. Skin biopsy. Rarely, your doctor may take a small sample of skin (biopsy). He or she will likely first apply a local anesthetic. The sample is examined under a microscope to determine the exact type of psoriasis and to rule out other disorders.
Psoriasis treatments reduce inflammation and clear the skin. Treatments can be divided into three main types: topical treatments, light therapy and systemic medications.
