decision on which hospitals to designate will be made between state and local health authorities and the hospital administration
prepared to transport patients with confirmed EVD to an Ebola treatment center, informed by discussions among public health authorities and referring and accepting physicians on a case-by-case basis
should be able to provide up to 96 hours of evaluation and care until the diagnosis is either confirmed or ruled out and discharge or transfer is completed

Idaho: progress to date Dec 11, 2014– survey sent to all Idaho acute care hospitals
Sent to CEO, COO and CNO level staff, asked for the survey to be completed by December 26
12 hospitals indicated interest initially; now 7
CDC site visit August 3-5

Results and Next Steps
Visits were very productive and well received
Both hospitals are considered assessment hospitals for planning purposes, although a few gaps remain (eg, laboratory protocols)
Additional hospitals are being contacted to determine interest in visit by Idaho team

Tularemia gram negative coccobacillus, Francisella tularensis, causes infection naturally found in animals, especially rodents, rabbits, and hares transmitted by multiple routes to humans:
– tick bite– deer fly bite (“deer fly fever”)– skinning infected rabbits (“rabbit fever”), muskrats, prairie dogs and other rodents– handling sick cats, pet hamster– eating under-cooked meat of infected animals– inhaling dust or aerosols during farming or landscaping activities, especially when
machinery (e.g. tractors or mowers) runs over infected animals or carcasses– drinking contaminated water (rare in US)
risk to laboratorians

Tularemia exposure to laboratorians
Lab personnel should be informed if tularemia is suspected clinically
BSL-2 practices recommended for handling clinical materials BSL-3 practices recommended for manipulations of positive
cultures Francisella tularensis is a Select Agent; notify public health of
suspected isolations even before confirmed if possible

Highly Pathogenic Avian Influenza outbreaks in the United States
Designation of highly pathogenic avian influenza (HPAI) is based on molecular characteristics of the virus and the ability of the virus to cause disease and mortality in chickens in a laboratory setting.
Between 1997 and 2014, the U.S. experienced one incident of HPAI in poultry.– 2004: H5N2 in Texas
• An outbreak of HPAI (H5N2) virus was reported in a flock of 7,000 chickens in south-central Texas.
• At that time, this was the first outbreak of HPAI in the United States in 20 years.
• No transmission to humans was reported.

“A MenB vaccine series may be administered to adolescents and young adults aged 16–23 years to provide short-term protection against most strains of serogroup B meningococcal disease. The preferred age for MenB vaccination is 16–18 years.”
Bexsero® (MenB-4C, 2 doses) and Trumenba® (MenB-FHbp, 3 doses) are both licensed. The two MenB vaccines are not interchangeable; the same vaccine product must be used for all doses.
MenB-FHbp or MenB-4C may be administered concomitantly with other vaccines indicated for this age, but at a different anatomic site, if feasible.

7698 participants received the vaccine; 7713 participants got placebo Mean follow-up of 3.2 years Herpes zoster in 6 participants in the vaccine group; 210 participants in the
placebo group Overall vaccine efficacy against herpes zoster was 97.2% (95% confidence
interval [CI], 93.7 to 99.0; P<0.001).
