Can architecture help in the fight against Malaria?

Because malaria is responsible for so many deaths in the developing world, its prevention is important. A new study shows that housing and architecture can reduce the impact of malaria.

25th April 2010 marks World Malaria day. Malaria is one of the leading causes of sickness and death in the developing world. Despite modern day scientific and technological advancements, a child dies of malaria every 30 seconds, even though malaria is preventable and curable  About 40% of the world’s population are at risk of malaria and there are 300 to 500 million clinical cases of malaria each year resulting in 1.5 to 2.7 million deaths[i].

Architecture: A new way to prevent malaria?

Presently malaria prevention prioritizes two main interventions; use of long lasting insecticide treated bed-nets, and indoor residual spraying (IRS). In addition, malaria drugs are used for prophylaxis, especially for the vulnerable groups in highly endemic areas, such as pregnant women. But what is the relationship between malaria, and architecture – particularly that of housing design? The increased number of inadequate housing has been seen to significantly contribute to the malaria burden. In 1994, slums settlements contributed to approximately 25% of the total malaria in Dindigul town in India.[ii]

Is it effective?

But are simple changes in house designs effective in malaria reduction? Mosquito-proofed houses have the potential for protecting people against malaria. A study by Steve Lindsay[iii] from the London School of Hygiene and Tropical Medicine highlights historic findings and urges us not to forget or ignore valuable lessons. Lindsay shows that since the 19th century, it was demonstrated that people could be protected from malaria by screening their homes against mosquitoes. In fact, there was a 96% reduction in cases of malaria among residents with mosquito-proof houses! In 1921, Mark Boyd found that better quality housing was associated with protection against malaria in Missouri, USA. The British army also mosquito-proofed their houses in Lahore, Pakistan, in 1925, and this reduced the incidence of malaria by 68%.

How do these architectural changes work?

The issue about the vector behavioural differences may be raised at this point.  The African mosquito Anopheles gambiae, which is one of the world’s most efficient, and dangerous vectors, is adapted for entering houses at night and feeding on people. When this mosquito reaches a wall when trying to enter a house, it flies upwards, and identifies openings or cracks to fly in, unlike other species that fly off sideways when encountered with a wall. Steve Lindsay noted that preventing this mosquito from entering a house either by installing ceilings or closing eaves should reduce malaria transmission, infection and disease. Also, because most mosquitoes searching for blood fly close to the ground, one of the simplest ways of avoiding mosquito bites is by building homes of the ground.

Yazoume Ye [iv] also suggested that house characteristics should be taken into account when designing health interventions against malaria infection. He carried out a study in Burkina Faso which compared the prevalence of malaria infection between children living in mud roofed houses, and iron sheet roofed houses, and found that, after controlling for potential confounders, children living in iron-sheet houses had a two times less risk of malaria infection compared to those living in houses with mud roofs.

Help us raise awareness!

The above listed studies highlight the importance of simple architectural designs as a means of vector control. If mosquito-proofed housing is used in conjunction with existing methods of vector control, the reduction in malaria infection incidence could be substantial. It is ARCHIVE’s ultimate goal, that we will be able to raise awareness and stimulate debate about the use of architecture as a means of mitigating malaria transmission.

Many thanks
I found this article very helpful. As an african I would say that main problem of our continent is lack of organization on using our people skills drive a agricultural and industrial revolution in Africa. We may sell all our resources and have all the money but it is the people knowledge which will drive our development. When I use to live in Congo, we use to have a combination of dry grass which we use to burn hours before bed time and it would do the trick of keeping out the mosquitos for days. What happen is that people where forced to move out of the area all grass land was cleaned up.
