Update: West Nile Virus activity--Eastern United States, 2000.
Data reported to CDC through the West Nile Virus (WNV) Surveillance System have shown an increase in the geographic range of WNV activity in 2000 compared with 1999, the first year that WNV was reported in the Western Hemisphere. In response to this occurrence of WNV, 17 states along the Atlantic and Gulf coasts, New York City, and the District of Columbia conducted WNV surveillance, which included monitoring mosquitoes, sentinel chicken flocks, wild birds, and potentially susceptible mammals (e.g., horses and humans). ⋯ Of the 13 jurisdictions, seven also reported severe neurologic WNV infections in humans, horses, and/or other mammal species. This report presents surveillance data reported to CDC from January 1 through November 15.

Updated recommendations from the Advisory Committee on Immunization Practices in response to delays in supply of influenza vaccine for the 2000-01 season.
On July 14, CDC reported a substantial delay in the availability of a proportion of influenza vaccine for the 2000-01 season and the possibility of a vaccine shortage. Since then, resolution of manufacturing problems and improved yields of the influenza A (H3N2) vaccine component have averted a shortage. Although safe and effective influenza vaccine will be available in similar quantities as last year, much of the vaccine will be distributed later in the season than usual. This update provides information on the influenza vaccine supply situation and updated influenza vaccination recommendations by the Advisory Committee on Immunization Practices (ACIP) for the 2000-01 influenza season.

Progress toward poliomyelitis eradication--Pakistan, 1999-June 2000.
In 1988, the World Health Assembly resolved to eradicate poliomyelitis globally by the end of 2000. Although polio remains endemic in Pakistan, which reported 60% of all polio cases in the World Health Organization's (WHO) Eastern Mediterranean Region during 1999, substantial progress has been made, particularly in acute flaccid paralysis (AFP) surveillance. This report summarizes progress toward polio eradication in Pakistan.

State and local health departments reported a provisional total of 100 confirmed measles cases to CDC in 1999. This total equals the record low number of cases reported in 1998 (1). Since 1997, measles incidence in the United States has remained < or = 0.5 cases per 1,000,000 population. This report describes the epidemiology of measles during 1999, which indicates that measles is not endemic in the United States.
