2005-2006 Season Summary

The flu activity level for the week ending May 13, 2006 has dropped to no activity. This does not mean that flu is not occurring in the state, but rather, at very low levels.

Reports were received from 9 of the 11 Health Service Regions (HSRs) for week 19. Only HSR 1 reported an increase in flu activity and only in Hansford County. A decrease in flu activity was reported in HSRs 6/5S, 7, and 8. Activity remained about the same in HSRs 4/5N and 11. HSR 2/3 reported no flu activity. HSR 9/10 did not report.

During week 19, no culture confirmed influenza A or B was identified by the DSHS laboratory or reported by any other laboratories in the state.

Five culture confirmed cases of flu were identified recently at the DSHS laboratory in specimens collected between April 19th and May 3rd by the San Antonio Metropolitan Health District. Four of the cases were identified as influenza B (Hong Kong). One was identified as influenza B (Shanghai).

Providers should continue to consider flu as a possible diagnosis and submit specimens to the DSHS laboratory even after flu season has ended. Unusual occurrences of respiratory illness should be reported to either the state or a local health department.

No institutional outbreaks or school closures were reported for week 19.
