The United Nations and World Bank launched a new campaign Friday to supply insecticide-treated bed nets for Africa.

The "Cover The Bed Net Gap" campaign will rally donor countries, multilateral institutions, the private sector, and the general public to achieve its goal of universal bed net coverage by 2010.

The campaign was initiated by the Roll Back Malaria Partnership, which was created 10 years ago by the World Health Organization, UN Children's Fund, UN Development Program and the World Bank to help countries burdened by malaria.

According to RBM, it has funds for only 99.5 million bed nets and still needs money for 150 million more bed nets to meet its 2010 quota.

The campaign immediately received a pledge of 20 million bed nets from British Prime Minister Gordon Brown and 10.5 million bed nets from the Malaria Initiative created this year by President Bush.

ExxonMobil is a corporate sponsor.

A charity special, "Idol Gives Back," conducted by the television talent show "American Idol" raised money for more than 1 million bed nets earlier this month.
