Pandemic Flu

from http://www.kingcounty.gov/healthservices/health/communicable/stopgerms.aspxA pandemic is a global disease outbreak. It is determined by how the disease spreads, not how many deaths it causes.

With thousands of islanders leaving the island on a daily basis, and the numbers flying throughout the world, it doesn't take germs long to hitch a ride back on the return trip. 

When a new influenza A virus emerges, a flu pandemic can occur. Because the virus is new, the human population has little to no immunity against it. With no immunity in the population, the virus spreads quickly from person-to-person worldwide. (- from www.flu.gov/pandemic/about/)

During times of severe flu, additional specific suggestions will be provided, but even before then a few guidelines may help:

  • Maintain supplies at home that reduce your exposure to others
  • Practice social distancing - don't touch hug/touch others as much if one of you has a known flu and sit further apart.
  • Follow routine germ avoidance techniques (below) especially closely.
