  2. Seasonal influenza • Influenza comes to Virginia every year • Season is October – May • Usually peaks December – February • This year, we can expect to see multiple flu viruses circulating • Influenza A/H3N2, 2009 Influenza A/H1N1, Influenza B • Influenza can have a large impact, especially in group residential settings

  3. Flu outbreaks reported last season

  4. Influenza activity this season

  5. VDH’s flu-related activities • Deliver public messages about covering cough, staying home while sick, washing hands and getting the flu vaccine • Commissioner’s “Dear Colleague” letter • Monitor flu activity based on outbreaks, laboratory findings, and visits for influenza-like illness (ILI) • Give advice on outbreak control to facilities, facilitate specimen collection for testing at state lab (DCLS) • Encourage and provide vaccine

  10. Seasonal norovirus • At the same time influenza is circulating, we also see a seasonal increase in the activity of norovirus, a gastrointestinal virus, in the community. • Norovirus causes vomiting and/or diarrhea. • It spreads easily from person-to-person. • It can have a large impact in group settings, such as schools, daycare facilities, long-term care facilities, and social gatherings.

  11. Norovirus outbreaks reported last season

  12. Norovirus activity

  13. VDH’s norovirus-related activities • Investigate and seek laboratory confirmation of many outbreaks • Monitor trends in outbreaks and outpatient visits for gastrointestinal illness • Give advice to facilities experiencing an outbreak • Make available information on the disease and disease prevention and control measures • Press release • Commissioner’s “Dear Colleague” letter • Guidelines for managing outbreaks in facilities

  14. MERS-CoV – Update • 163 cases reported (CDC, 12/5/2013) • 71 deaths (44% fatality rate) • Cases in 10 countries: 80% in Saudi Arabia • No cases in United States • No sustained person-to-person transmission, but can spread person-to-person during close contact • Family caregivers • Healthcare settings • VDH and DCLS collaborated to test 4 people for MERS-CoV • All met screening criteria for testing • All tested negative

  15. Novel influenza – Update • Influenza A H7N9 • All cases to date have been in China • 137 cases (45 deaths) reported (WHO, as of 10/25/2013) • China reporting a few cases this autumn • 1 case in Taiwan and 2 cases in Hong Kong, all associated with travel to mainland China • VDH and DCLS collaborated to test 6 people for H7N9 • All met screening criteria for testing • All tested negative

  16. Tracking and responding to seasonal and emerging infections keeps VDH and DCLS staff busy and challenged. • Any questions?
