Influenza a highly contagious upper respiratory viral infection
Flu season September to April; peaks Nov-March
Influenza viruses serotypes Type A, B, & C; each has a slightly different genome
and surface proteins
Hemagglutin (H) & neuramindase (N) Antigens present on influenza virus; H allows the
virus to enter the cell & N allows the virus to spread;
Type A Influenza has the most variety of H & N
antigens
Type A Influenza - the most virulent and contagious Influenza
- Contains H & N antigens
- Many animals can be a vector for it
- Mutates often and has many different strains
Antigentic Shift When a virus previously impacting animals, mutates
to be able to infect humans; occurs when the animals
becomes infected with two different types of viruses
that combine together to form a new strain of virus;
since it's a new strain humans will not have immunity
against it; is responsbile for many recent pandemics
Why is the Flu shot needed annually? There are several different strains of the virus; the
strain present each year is different than the one last
year; it can be completely new or one not present
for a long time, so the vaccine would not protect
against the strain
, How does Influenza spread? - From infected animals to humans via direct contact
or indirect contant (i.e. feces)
- From human to human via inhaled droplets from
sneezing or coughing or direct contact with
contaiminated surfaces
Influenza Clinical Manifestations - Adurbt onset of chills, fever, and myalgia
- Headache, cough, sore throat, and fatigue
- Lung sounds normal unless complications present
Influenza Complications - Pneumonia (viral or secondary bacterial)
- Ear or sinus infections
- Dehydration (particularly in older adults)
- Acute otitis media (ear infection)
- Sinusitis
- Bronchiolitis
- Reye syndrome (in children who take Asprin)
- Febrile seizures (in children)
- Encephalitis (in children)
Who is at greatest risk of developing - Older adults
complications related to Influenza? - Young children <6 months
- Pregnant women
- Those w/ chronic health conditions
When is the best time to receive the September before flu exposure, but it can be taken
flu vaccine? any time during the flu season
Nursing Management of Influenza - Promoting prevention (flu vaccines, washing hands
- Relief of symptoms/supportive care (rest, hydration,
analgesics, and antipyretics)
- Preventing secondary infections
