There are many success stories. Here are a few:

The Net Depot
The Port Moresby Rotary Club received a grant from the Australian government for nets after some Rotarians did a very successful project including nets on Karkar Island. The club bought 10,000 nets. They sell the nets at their cost to anyone who wants to buy them and then use the money to buy more nets. A club member donates room for the nets in a warehouse he owns.

Note: This 'Net Depot' - warehouse idea has been floated to many Rotary Clubs but no one else has taken it up. Some clubs now claim they 'can't find any nets to buy', so the time may be coming.

Rotary Club as Malaria Agency
An earlier government of Papua New Guinea had a hard time accounting for some money from nets their agent had sold. Long story short, they asked the Rotary Club to manage the distribution of mosquito nets. At first, the club used the money to buy more nets as fast as possible to replenish the stores. After a couple seasons they figured out how many nets they needed to keep in stock. They took the extra money and put it on interest in government bonds. They use the interest to hire a clerk - part time - at $50 per month to keep track of the nets. The interest more than covers the wages.

All the funds are fully accounted for. They found 'full financial transparency' is easy when you have Rotarians running the show. They take no salary, donate the warehouse and any money laying around earns interest that gets plowed back into nets, above what the clerk earns.

More recently, Ron Seddon helped the government write a grant to the Global Fund for Aids, TB and Malaria for Papua New Guinea. Over the next few years the country of 5.5 million people will be receiving enough mosquito nets to cover everyone at risk from malaria. They may be able to control malaria completely in the entire country. Eradication is a ways off, until they can remove malaria from all of Asia. The island nations of Indonesia and the Philippines may be hard.

The Solomons
In the Solomon Islands malaria has been notoriously nasty and persistent. In the mid-1990's Rotarians from the local clubs and Australia brought in mosquito nets, spraying, diagnostic testing and medicines. They took the rates of malaria down by 80% or more. Death rates from malaria went to zero. They also introduced blood screening for HIV/AIDS and a few other improvements to health care.

Then the government changed and projects couldn't somehow continue. In a few years malaria was back to being the worst in the Pacific, over 300 infected bites per person per year. After much persistence the Rotarians returned, (2002-2003) this time armed with grants from Rotary Foundation, WHO, and the Gates Foundation. They built clinics, put up mosquito netting, sprayed for mosquitoes and taught local health workers how to deal with malaria, among other diseases. Again the rates of malaria plummeted. Intertribal warfare led the Australian Army to make the Solomons a protectorate. Maybe they'll control malaria completely -for a while- before they leave.
