  • S. Carolina 2015-16 Flu Season

    DHEC compiles the South Carolina flu data for a weekly surveillance report called, Flu Watch.


    Influenza Activity Synopsis:
    During MMWR week 43 influenza activity in South Carolina generally decreased, with a slight increase in positive rapid tests. Flu activity is currently low. South Carolina reported SPRORADIC activity.

    Laboratory surveillance:
    * 138 laboratory-confirmed cases of influenza were reported from 21 counties.
    * 255 (56.7%) of all laboratory-confirmed cases this season are influenza A, 177 (39.3%) are influenza B, 12 (2.7%) are influenza A/B, and 6 (1.3%) are influenza unknown subtype.

    ILI Activity (South Carolina baseline is 2.05%):
    * The percentage of visits to sentinel providers for influenza-like illness (0.55%) was below South Carolina?s baseline. ILI percentages represent ILI activity reported by less than half of enrolled sentinel providers. Therefore, ILI percentages may not be representative of actual flu activity.

    Hospitalizations:
    * 13 laboratory confirmed influenza-associated hospitalizations were reported. Since October 4, 2015, 63 laboratory confirmed influenza associated hospitalizations have been reported.

    Deaths:
    * No laboratory confirmed influenza-associated deaths were reported. Since October 4, 2015 five laboratory confirmed influenza associated deaths have been reported.

    MMWR Week 44 at a Glance:

    Influenza Activity Synopsis: During MMWR week 44 influenza activity in South Carolina remained low. South Carolina reported SPRORADIC activity.

    Laboratory surveillance:
    * 98 laboratory-confirmed cases of influenza were reported from 17 counties.
    * 313 (57.1%) of all laboratory-confirmed cases this season are influenza A, 206 (37.6%) are influenza B, 23 (4.2%) are influenza A/B, and 6 (1.1%) are influenza unknown subtype.

    ILI Activity (South Carolina baseline is 2.05%):
    * The percentage of visits to sentinel providers for influenzalike illness (0.25%) was below South Carolina?s baseline. ILI percentages represent ILI activity reported by less than half of enrolled sentinel providers. Therefore, ILI percentages may not be representative of actual flu activity.

    Hospitalizations:
    * 4 laboratory confirmed influenza-associated hospitalizations were reported. Since October 4, 2015, 67 laboratory confirmed influenza associated hospitalizations have been reported.

    Deaths:
    * No laboratory confirmed influenza-associated deaths were reported. Since October 4, 2015 five laboratory confirmed influenza associated deaths have been reported

      Influenza Activity Synopsis:
      During MMWR week 45 influenza activity in South Carolina remained low.
      South Carolina reported SPRORADIC activity.

      Laboratory surveillance:
       172 laboratory-confirmed cases of influenza were reported from 22 counties.
       444 (56.9%) of all laboratory-confirmed cases this season are influenza A, 299 (38.3%) are influenza B, 32 (4.1%) are influenza A/B, and 6 (0.8%) are influenza unknown subtype.
      * During the most recent MMWR week, 172 positive rapid antigen tests were reported. Of these, 97 were influenza A, 70 were influenza B, and 5 were influenza A/B. This compares to 271 during this same week last year.

      ILI Activity (South Carolina baseline is 2.05%):
       The percentage of visits to sentinel providers for influenzalike illness (0.36%) was below South Carolina?s baseline. ILI percentages represent ILI activity reported by less than half of enrolled sentinel providers. Therefore, ILI percentages may not be representative of actual flu activity.

      Hospitalizations:
       18 laboratory confirmed influenza-associated hospitalizations were reported. Since October 4, 2015, 89 laboratory confirmed influenza associated hospitalizations have been reported.

      Deaths:
       No laboratory confirmed influenza-associated deaths were reported. Since October 4, 2015 five laboratory confirmed influenza associated deaths have been reported.
      * For the current MMWR reporting week, 18 laboratory confirmed influenza-associated hospitalizations were reported by 53 hospitals. No laboratory confirmed influenza-associated deaths were reported. Since October 4, 2015 89 laboratory confirmed influenza-associated hospitalizations and 5 laboratory confirmed influenza-associated deaths have been reported. Laboratory confirmation for hospitalizations and deaths includes culture, PCR, DFA, IFA, and rapid
