Growing up in India, mosquito nets were an essential part of life. I slept under them as a child in Bangalore, with their ropes tied to bedposts, doors, closets, window grills—anything that would offer support at the right height. It was like pitching a tent every night, and the occasional dramatic collapse would result in much helpless laughter. Later, going to college on the banks of the slow-flowing Koovam river in Madras (now Chennai), I tucked myself under a net in my dormitory at about 6 p.m. to avoid the twilight assault of mosquitos from the water. In fact, particularly after a bad attack of malaria when I was a child, a lot of my life was lived perforce under a mosquito net, until electric repellent gadgets reached the market and nets somewhat lost their popularity.

Recently, sitting in Halima Ibrahim’s house in Majengo, a neighborhood in the coastal city of Mombasa, and talking about the new mosquito nets her family had just received from the Kenyan government, I felt instantly at home in her tiny living room. It was packed from corner to corner with family and friends, all brimming with opinions about nets old and new. Everybody talked about malaria and what a problem the disease was in the community. The nets that had just been distributed to them free of cost would make a huge difference, they said, protecting them from being bitten by mosquitos, and saving them considerable expense. Many of the families on the street simply could not afford to buy durable and effective nets at the prices they commanded in the local market.
