Abstract
In 1988, the World Health Assembly resolved to eradicate poliomyelitis by December 31, 2000 (1). Although progress has been extraordinary (2), full implementation of polio eradication strategies has been delayed in several countries affected by war. The Democratic Republic of Congo (DRC) has experienced continual armed conflict since October 1996. As a result, DRC is the last country in the African Region of the World Health Organization (WHO) to implement National Immunization Days (NIDs*). DRC is an important global reservoir for wild poliovirus and shares more than 5580 miles (9000 km) of border with nine countries; in at least seven of these countries polio is endemic. The large area of DRC, substantial amount of poverty, weak health-care infrastructure, poor transportation and communication, and competing demands for resources present considerable challenges to polio eradication. This report summarizes information on the existing health-care infrastructure and routine coverage, information from NIDs carried out in 1999, and results from the recently established surveillance system for acute flaccid paralysis (AFP).

Summary
INFLUENZA A (H3N2) VIRUSES WERE THE predominant viruses isolated in the United States and worldwide during. States was similar to the previous two seasons, mortality measurements attributed to pneumonia and influenza (P&I) were unusually high. The 1999-2000 influenza vaccine was well matched to circulating influenza viruses. The 2000-01 influenza season will be the first for which influenza vaccination is recommended for all persons aged greater than or equal to 50 years. This report summarizes surveillance for influenza in the United States and worldwide during the 1999-2000 influenza season, describes the composition of the 20002001 influenza vaccine, and highlights changes in the recommendations for prevention and control of influenza
