Synopsis for March 10, 2000
Update: Influenza Activity -- United States, 1990-2000 Season
During the 1999-2000 influenza season, the level and timing of flu activity appears within range of the previous 5 years.

In most areas of the country flu activity now appears to be decreasing. The 1999-2000 flu season peaked during late December and early January.
The predominant viruses isolated this season were well-matched to this season's vaccine. These viruses, influenza A (H3N2), are antigenically
similar to the viruses that have predominated since the 1997-98 influenza season. During the 1999-2000 season, flu activity, as detected by
three of four influenza surveillance systems, have been within the range seen during the previous 5 years. The findings of pneumonia and
influenza mortality surveillance from the 122 Cities Mortality Reporting System (the fourth influenza surveillance system) are difficult to
compare with previous years because of significant changes in the system this year.
Update: Surveillance for West Nile Virus in Overwintering Mosquitoes -- New York, 2000
Note: This article ONLY is not embargoed
As recommended by CDC, New York City and New York State Departments of Health collected hibernating Culex
mosquitoes this winter.

CDC's Fort Collins, Colorado, laboratory tested the collections from New York to determine if West Nile virus might persist throughout the
winter and possibly initiate a transmission cycle this spring. Not unexpectedly, 3 of the 69 pools containing adult Culex pipiens
mosquitoes, collected in New York City in January and February, had low but detectable levels of West Nile viral RNA. The positive mosquito
pools were collected from Fort Totten. The public health significance of the identification of West Nile viral RNA in overwintering mosquitoes
is unclear, and whether West Nile virus will persist in the New York area also is uncertain. However, CDC recommends continued vigilance in
surveillance to detect mosquitoes, birds, or people infected with the West Nile virus. CDC further recommends eliminating breeding areas and
early application of larvicides to Culex larval habitats to reduce the potential for the West Nile virus transmission cycle to recur.
Update: Pulmonary Hemorrhage/Hemosiderosis Among Infants -- Cleveland, Ohio 1993-1996
A review by CDC and outside experts has identified shortcomings in a previous report of acute pulmonary hemorrhage/hemosiderosis in infants
living in Cleveland.

In December 1994 and January 1997, articles in the MMWR described infants from Cleveland with pulmonary hemosiderosis due to exposure to the
molds Stachybotrys chartarum (commonly called, Stachybotrys atra). However, a review by CDC and other experts has determined
that the association between the mold and illness in the infants was not proven. Serious shortcomings in the collection, analysis, and reporting
of the data in the previous studies resulted in inflated measures of association, and restricted interpretation of the reports. Copies of the
report of the working group are available online at http://www.cdc.gov/od/ads/
