The Tamil Nadu state government of India launched a project to create an online reporting system intended to track the occurrence pattern for communicable disease, in order to help health planners prevent and control the spread of disease. The web-based system will allow tracking of 14 diseases, including malaria, dengue fever, measles and typhoid.

India's Directorate of Public Health and Preventive Medicine controls the system, which generates data from:

• Primary health centers;
• Urban dispensaries;
• Health posts;
• Taluk, or subdivisions of a district, hospitals;
• District headquarters hospitals; and
• Government/private medical college hospitals.

District health authorities have also been commissioned to obtain data from pediatric wards, casualty, outpatient and inpatient departments, and private hospitals, said A. Palanichamy, deputy director of health services.
