A team of spray operators and supervisors set out in the early morning to begin household spraying in Matabele North Province, Zimbabwe, near the northern border with Zambia. Spraying is done once a year to kill malarial mosquito larvae in the remote clusters of homesteads, with each spray operator walking from village to village, 7 days a week for a period of 21 days. The work to reach all homes in the province lasts 63 days, and employs 180 spray operators, to protect a population of approximately 780,000 people. The activities are part of a cross-border initiative between Zimbabwe and Zambia to eliminate malaria in the Zambezi valley, thereby paving the way for social and economic prosperity in the region.
