Avian Flu

How many people were estimated to have been killed worldwide from the Spanish Flu in the space of 18 months?

10 Thousand to 20 Thousand 500,000 to 1 million 20 million to 25 million 50 million to 100 million

What was unusual about the Victims of the Spanish flu?

Many were young adults and otherwise healthy Many were infants Many were older Many were females

What treatment was used successfully by military doctors for the Spanish flu that may be used again against the avian flu:

Leeches Bird feather vaccines Injection of blood from those who had recovered from the flu Salt water scrub

General flu viruses are classified into three types. They are:

A, B, C Contagious, non-contagious and dormant 1, 2, 3 Mild, Moderate, and Severe

What is the natural host for all known subtypes of influenza A?

Domesticated birds Wild birds Poultry Pigs

Which of the following is true about influenza viruses

They never change They are non-contagious Although they are uncomfortable, they pose no real health danger They are dynamic and are continuously evolving

An Antigenic shift refers to:

A slow change in the virus producing a new subtype of not currently carried in humans. An abrupt, major change producing a new subtype of virus not currently carried in people. A shift in illness when a flu victim contracts pneumonia. An allergic reaction to a flu vaccination

For influenza A, what two proteins combine to determine the subtypes' names?

Hemagglutinin (HA) and Neuraminidase (NA). Alkaline (AG) and Bendanase (BD) Sufamin (SF) and kaladase (KA) Mulical (ML) and Zebramase (ZB)

The following are prominent subtypes of the avian influenza A viruses that are known to infect both birds and people EXCEPT:

Influenza A H2 Influenza A H5 Influenza A H7 Influenza A H9

Which of the following IS NOT a condition that will cause a global influenza pandemic to occur

A new subtype of influenza A virus is introduced into the human population. The virus causes serious illness in humans. The virus can spread easily from person to person in a sustained manner. All three are conditions that may cause a global pandemic.

Which is not a true statement about inter-bird infections of avian flu:

It does not usually harm wild birds, but can harm domesticated birds. Wild birds carry it around naturally in their intestines. The avian flu cannot harm any types of birds; only humans. Susceptible birds become infected when they have contact with contaminated secretions or excretions.

The highly pathogenic form of avian flu has a mortality rate in poultry that can reach 90-100% often within 48 hours.

True False

How does the avian flu change so that it can infect humans and create a pandemic?

An antigenic shift--Influenza A viruses from two different species infect the same person or animal creating a virus from which humans have little or no immune protection. A gradual change of the virus known as an antigenic drift. A rapid change in the weather causes the virus to mutate. Transfat oil used in frying chicken creates a playground for the flu virus.

Stated symptoms of avian influenza in humans include the following EXCEPT:

Typical human influenza-like symptoms (e.g., fever, cough, sore throat, and muscle aches) Eye infections Severe respiratory diseases Other severe and life-threatening complications. The sudden desire to fly.

What strain of the flu virus has caused the largest number of detected cases of severe disease and death in humans.

H5N1 H7N2 H9N3 R2D2

Studies done in laboratories suggest that some of the preblockedion medicines approved in the United States for human influenza viruses should work in treating avian influenza infection in humans.

True False

Which of the following is a vaccine known to work against the H5N1 flu strain?

Amantadine Rimantadine Oseltamavir Zanamavir There currently is no commercially available vaccine to protect humans against H5N1 virus

What cautions should be used when treating patience with avian flu?

Pay careful attention to hand hygiene before and after all patient contact Use dedicated equipment such as stethoscopes, disposable blood pressure cuffs, disposable thermometers, etc. Wear eye protection when within 3 feet of the patient Place the patient in an airborne isolation room (AIR). All of the above
