What is emergency preparedness

A

To achieve the vision of the Federal Emergency Management Agency (FEMA):
“FEMA will work to prepare the Nation for disasters by encouraging individuals, government entities, and public and private groups at all levels to become informed of the risks they face, to make decisions that help keep people, property, and institutions out of harm’s way, and to possess the capability and knowledge needed to act when disasters occur.”

Hurricane Harvey - 2017

A
  • Hazardous Materials- explosions at Arkema chemical plan (air contamination), ExxonMobil releases, other plants leaking chemicals into the floodwaters, 20+ Superfund sites
  • Building Environment- MOLD!
  • Vector Control- mosquitoes, including those that carry Zika
  • Biologic and Infectious Waste- at least a dozen sewage overflows (as of 9/28/17, still 7 inoperable wastewater facilities affecting 1,794 customers)
  • Vibrio vulnificus is a bacterium that lives in the Gulf Coast waters and kills one in seven people it infects; it’s one of several pathogens that can lead to necrotizing fasciitis, which is commonly referred to as “flesh-eating disease.”
  • Water Security- 200,000 people subject to boil water orders (as of 9/28/17, still 15 counties, 38 active boil water notices for 12,285 customers)

Q

zika virus

A

—–80% of people with zika will have no symptoms
At risk populations
—–Pregnant women, women thinking about pregnancy
———-Zika virus can spread from mother to unborn baby
———-Infection during pregnancy linked to birth defects
How zika virus spreads
—–Mosquito bites
—–Sexual transmission

8
Q

How does zika spread

A

a mosquito bites a person infected with zika –> a mosquito becomes infected –> a mosquito will often live in a single house during its lifetime –> the infected mosquito bites a family member or neighbor and infects them –> more mosquitoes get infected and spread the virus –> more members in the community become infected –>

other less common ways people get zika:

  • during pregnancy –> pregnant women can pass zika to her fetus causing a severe birth defect
  • through sex
  • through blood transfusion
