Bird Flu

Birds, just like people, get the flu. Bird flu viruses infect birds, including chickens, other poultry and wild birds such as ducks. Most bird flu viruses can only infect other birds. However, bird flu can pose health risks to people. The first case of a bird flu virus infecting a person directly, H5N1, was in Hong Kong in 1997. Since then, the bird flu virus has spread to birds in countries in Asia, Africa and Europe.

Human infection is still very rare, but the virus that causes the infection in birds might change, or mutate, to more easily infect humans. This could lead to a pandemic, or a worldwide outbreak of the illness.

During an outbreak of bird flu, people who have contact with infected birds can become sick. It may also be possible to catch bird flu by eating poultry that is not well cooked or through contact with a person who has it. Bird flu can make people very sick or even cause death. There is currently no vaccine.

Pressure Sores

Pressure sores are areas of damaged skin caused by staying in one position for too long. They commonly form where your bones are close to your skin, such as your ankles, back, elbows, heels and hips. You are at risk if you are bedridden, use a wheelchair, or are unable to change your position. Pressure sores can cause serious infections, some of which are life-threatening. They can be a problem for people in nursing homes.

You can prevent the sores by

* Keeping skin clean and dry

Weight Loss Surgery

If you're very overweight and can't lose pounds with a healthy diet and exercise, surgery might be an option for you. The surgery is usually for men who are at least 100 pounds overweight and women who are at least 80 pounds overweight. If you are somewhat less overweight, surgery still might be an option if you also have diabetes, heart disease or sleep apnea.

Weight loss surgery limits the amount of food you can take in. Some operations also restrict the amount of food you can digest. Many people who have the surgery lose weight quickly. If you follow diet and exercise recommendations, you can keep most of the weight off. The surgery has risks and complications, however, including infections, hernias and blood clots.
