Experts Seek More Attention to Buruli Ulcer Disease


迅雷专用

This is the VOA Special English Development Report.

Buruli溃疡病(Buruli ulcer disease,BUD),又称Bairnsdale溃疡病,是由溃疡分枝杆菌(Mycobacterium ulcerans)感染的一种慢性溃疡性皮肤病。Cook于1897年在乌干达首次发现本病。1962年乌干达Buruli地区不少儿童皮肤罹患本病,因此将其命名为BUD。近10年来全球BUD发病率不断上升。

Buruli ulcer is a bacterial disease that eats away muscle tissue. People can become disabled. They may even need to have an arm or leg removed. Buruli ulcer disease can be easily treated with antibiotics. Yet people often do not get medical help until the damage already has been done.

Doctor Alexander Tiendrebeogo from the World Health Organization says the disease causes no pain at first. The condition usually begins as a swelling on the skin. Then large ulcers form. These breaks destroy skin and soft tissue, sometimes all the way down to the bone.

Buruli ulcer is a disease found in tropical climates. It belongs to the same family of bacteria as those that cause tuberculosis and Hansen's disease, also known as leprosy.

Cases have been reported in Africa, the Americas, Asia and the western Pacific. At least thirty nations have had cases of Buruli ulcer disease. But experts say this condition has not gotten as much attention as it should.

It was just discussed during an international health conference held in Benin. Benin, Ghana and Ivory Coast have thousands of current cases of Buruli ulcer disease. Health officials believe other countries in West Africa have unreported cases.

Scientists are not sure how Buruli ulcer disease spreads or even how it develops in nature. They suspect it may involve mosquitoes or other organisms that live in water.

A British doctor reported the first cases of what was probably Buruli ulcer in eighteen ninety-seven in Uganda. Sir Albert Cook of the Church Missionary Society described the condition in patients at his Mengo Hospital in Kampala.

In nineteen forty-eight, Peter MacCallum and other scientists in Australia reported six cases near Melbourne. They also identified the bacterium that causes Buruli ulcer. The first complete genetic map was published in two thousand seven. That genome may lead to better treatment and control of the disease.

Public health officials hope that a treatment can be developed that does not require injections. If people could take the medicine by mouth, they would not need to travel to health clinics.

In the nineteen sixties there were many cases in an area then called Buruli County in Uganda. That explains the name Buruli ulcer, the most commonly used name for the disease.

And that's the VOA Special English Development Report. It was written by Jerilyn Watson.
