ABSTRACT
Integrated Disease Surveillance and Response (IDSR) is a strategy developed by the World Health Organization. Regional Office for Africa in 1998. The Ministry of Health; Tanzania has adopted this strategy for strengthening communicable diseases surveillance in the country. In order to improve the effectiveness of the implementation of IDSRmonitoring and evaluating the performance of the surveillance system; identifying areas that require strengthening and taking action is important. This paper presents the findings of baseline data collection for the period October - December 2003 in 12 districts representing eight regions of Tanzania. The districts involved were Mbulu; Babati; odoma Rural; Mpwapwa; Igunga; Tabora Urban; Mwanza Urban; Muleba; Nkasi; Sumbawanga Rural; Tunduru and Masasi. Results are grouped into three key areas: surveillance reporting; use of surveillance data and management of the IDSR system. In general; reporting systems are weak; both in terms of receiving all reports from all acilities in a timely manner; and in managing those reports at the district level. Routine analysis of surveillance data is not being done at facility or district levels; and districts do not monitor the performance of their surveillance system. There was also good communication and coordination with other sectors in terms of sharing information and resources. It is important that districts' capacity on IDSR is strengthened to enable them monitor and evaluate their own performance using established indicators
