Dengue

What is Dengue?

Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. Almost half of the world’s population, about 4 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk.


New Dengue Vaccine

A new dengue vaccines is now recommended for U.S. territories and freely associated states. The vaccine is approved for use in children aged 9 to 16 years with laboratory-confirmed previous dengue virus infection and living in areas where dengue is endemic (common). The vaccine is not approved for use in U.S. travelers who are visiting but not living in an area where dengue is common.


About Dengue: What You Need to Know

Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. These mosquitoes also spread Zika, chikungunya, and other viruses.

Almost half of the world’s population, about 4 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk.

Each year, up to 400 million people get infected with dengue. Approximately 100 million people get sick from infection, and 40,000 die from severe dengue.

Dengue is caused by one of any of four related viruses: Dengue virus 1, 2, 3, and 4.  For this reason, a person can be infected with a dengue virus as many as four times in his or her lifetime

Legg–Calve–Perthes disease

  Legg–Calve–Perthes disease Overview Legg-Calve-Perthes (LEG-kahl-VAY-PER-tuz) disease is a childhood condition that occurs when blood supply to the ball part (femoral head) of the hip joint is temporarily interrupted and the bone begins to die. This weakened bone gradually breaks apart and can lose its round shape. The body eventually restores blood supply to the ball, and the ball heals. But if the ball is no longer round after it heals, it can cause pain and stiffness. The complete process of bone death, fracture and renewal can take several years. To keep the ball part of the joint as round as possible, doctors use a variety of treatments that keep it snug in the socket portion of the joint. The socket acts as a mold for the fragmented femoral head as it heals. Symptoms Symptoms of Perthes disease include: Limping. Pain or stiffness in the hip, groin, thigh or knee. Limited range of motion of the hip joint. Pain that worsens with activity and improves with rest. Perthes diseas...
