Voice of America, Surge in Dengue Fever Raises Alarm in Southeast Asia

Surge in Dengue Fever Raises Alarm in Southeast Asia

In Malaysia, more than 20,000 people caught dengue fever in the first five months of this year, 50 percent more than in the same period a year earlier. Forty-eight people died of the disease, an increase in mortality of about 70 percent compared to 2006. Dengue fever is also on the rise in Vietnam and Thailand. Singapore reported almost 3,000 dengue cases in the first half of this year, more than twice as many as in the same period last year.

In Cambodia, the disease killed at least 109 children this year - three times as many as in the first half of 2006. Ngan Chantha, director of Cambodia's national anti-dengue fever program, fears the death toll could rise even more in coming months.

Chantha says he is worried because it is only June, and dengue fever usually peaks at the height of the rainy season in July and August.

Dengue is a viral disease transmitted mainly by a type of mosquito common in Southeast Asia. Patients suffer from high fever, nausea and intense joint pain. In severe cases, the disease can be fatal.

The earlier-than-usual arrival of the rainy season in parts of the region this year is partly to blame for the increase in dengue cases. The growth of cities across the tropics is another cause.

The mosquitoes that carry the disease usually breed in containers filled with rainwater, such as discarded plastic bottles or tires. In Southeast Asia's rapidly growing cities with sprawling construction sites and garbage dumps, mosquitoes find ample breeding ground.

Steven Bjorge is an epidemiologist for the World Health Organization in Indonesia. He says increased migration into urban centers has increased the frequency of outbreaks. Migrants, unlike people born in the city, have not built up an immune system to different strains of the virus.

"In Jakarta, a city of 12 million people, there is a lot of in-migration from rural areas of Java, Bali and Sumatra and in many cases, those people are not immune so they provide the place that another epidemic could get started," said Bjorge. Bjorge says travel also spreads the disease. One or two infected tourists traveling to the Maldives, for example, could cause a small epidemic there if mosquitoes that transmit the disease bite them.

There is no treatment or vaccine for dengue fever. The only way to prevent it is to remove the mosquitoes' breeding grounds.

Dengue is a viral disease transmitted mainly by a type of mosquito common in Southeast Asia. Patients suffer from high fever, nausea and intense joint pain. Les patients souffrent de forte fièvre, de nausées et de douleurs articulaires intenses. In severe cases, the disease can be fatal.

The earlier-than-usual arrival of the rainy season in parts of the region this year is partly to blame for the increase in dengue cases. L'arrivée plus précoce que d'habitude de la saison des pluies dans certaines parties de la région cette année est en partie responsable de l'augmentation des cas de dengue. The growth of cities across the tropics is another cause.

The mosquitoes that carry the disease usually breed in containers filled with rainwater, such as discarded plastic bottles or tires. Les moustiques porteurs de la maladie se reproduisent généralement dans des récipients remplis d'eau de pluie, tels que des bouteilles en plastique ou des pneus jetés. In Southeast Asia’s rapidly growing cities with sprawling construction sites and garbage dumps, mosquitoes find ample breeding ground. Dans les villes en croissance rapide d'Asie du Sud-Est avec des chantiers de construction tentaculaires et des dépotoirs, les moustiques trouvent un terrain fertile. 広大な建設現場とゴミ捨て場がある東南アジアの急速に成長している都市では、蚊は十分な繁殖地を見つけます。

"In Jakarta, a city of 12 million people, there is a lot of in-migration from rural areas of Java, Bali and Sumatra and in many cases, those people are not immune so they provide the place that another epidemic could get started," said Bjorge. 「人口1200万人の都市ジャカルタでは、ジャワ、バリ、スマトラの農村地域からの移民が多く、多くの場合、これらの人々は免疫がないため、別の流行が始まる可能性のある場所を提供します。 「ビョルゲは言った。 Bjorge says travel also spreads the disease. One or two infected tourists traveling to the Maldives, for example, could cause a small epidemic there if mosquitoes that transmit the disease bite them. たとえば、モルディブに旅行する1人か2人の感染した観光客は、病気を媒介する蚊が彼らを噛んだ場合、そこで小さな流行を引き起こす可能性があります。

There is no treatment or vaccine for dengue fever. Il n'existe aucun traitement ni vaccin contre la dengue. デング熱の治療法やワクチンはありません。 The only way to prevent it is to remove the mosquitoes' breeding grounds. La seule façon de l'empêcher est d'éliminer les lieux de reproduction des moustiques. Satu-satunya cara untuk mencegahnya adalah dengan menghilangkan tempat berkembang biak nyamuk.
