Pneumonia Etiology Research for Child Health (PERCH)
- Start Date:
- End Date:
The PERCH project is a rigorous multi-country, case-control study of hospitalized pediatric patients with severe lower respiratory tract illnesses (hereafter referred to as pneumonia) to determine the etiology and risk factors associated with the syndrome. The project is going to be conducted with partner organizations in Kenya, New Caledonia, Bangladesh, Mali, South Africa, Zambia, Thailand and Gambia. Laboratory techniques that have remained vastly unchanged for more than a century have limited our understanding of pneumonia etiology. By applying modern tools with standardized methods, PERCH will contribute to new, precise information to guide the development of new vaccines and treatments.
