More than 17 million of Ghana's 22 million people are infected by malaria every year, costing the nation a colossal 850 million cedis (US$94 million)for treatment alone. These figures probably underestimate the real burden, as many cases go unreported.

Malaria also has a huge indirect cost on Ghanas economy due to lost productivity. Those infected by malaria are in and out of hospital and unable to work. Malaria takes an especially heavy toll on farmers. Swarms of mosquitoes make it impossible for farmers and their families to sleep indoors, especially during the rainy seasons when they are forced to sleep outdoors around bonfires.

Malaria makes it difficult for our fledgling industries to get off the ground because it scares away tourists and investors – both major potential sources of income and jobs. A country where 85 percent of the population falls sick every year is not likely to attract investors, in search of a robust and healthy workforce, or tourists, looking for amusement and leisure.

The productivity of future generations is also being undermined by this epidemic. Pregnant women and children under five are a significant proportion of those infected each year. Even if children survive the infection, serious illness at such an early age stunts development, with lifelong repercussions. This loss of potential is unnecessary and unacceptable.

Our health system is utterly ill-equipped to deal with the malaria crisis, even with the government's recent introduction of a national system of socialized healthcare. Some of the blame of Ghana's failure to tackle malaria must fall on the World Health Organization, whose recommendations have led to rising infection levels. Until recently, the WHO advocated the use of insecticide-treated bed nets, almost to the exclusion of other proven measures.

While bed nets have their uses, they are not a panacea. For bed nets to be effective, they must first be distributed among the population, and second, be used correctly. Poor roads, isolated communities and a fragmented healthcare system make distribution very difficult. To remain effective, bed nets also need to be dipped in toxic pesticide every three months. And people often find them too hot to sleep in, or use them for fishing nets or even wedding dresses!

This all means that the number of people contracting malaria is on the rise, but the recommended treatment – Artemisinin Combination Therapy (ACT) – is beyond the financial reach of most Ghanaians. Our national health system is not able to shoulder the spiraling cost of treatment, either. We need to consider different approaches if we are to free Ghana from the economic and social destruction malaria brings.

One such alternative is Indoor Residual Spraying, which involves spraying the interior walls of dwellings with a small amount of DDT. This acts as an irritant to the mosquitoes, which prevents them from coming in the house in the first place. Those that do make it inside are quickly repelled outside. This can effectively stop the transmission of malaria.
