Influenza

Influenza

DEFINITION
Influenza (also known as seasonal flu) is a highly infectious
illness caused by a flu virus.
SIGNS AND SYMPTOMS
Symptoms of Influenza appear suddenly, unlike the common cold,
where less-severe symptoms appear gradually. The gap between
exposure to the flu virus and development of symptoms is 2 to 3
days. A person becomes infectious approximately one day before the
onset of symptoms. Acute symptoms last for 3 to 7 days with
complete recovery taking up to three weeks. Symptoms
include: 
  • Fever and/or chills. Temperature usually reaches 38 degrees
    C/100 degrees F and can rise to 41 degrees C/105.8 degrees F. (The
    common cold usually involves a small increase in temperature.)
  • Body aches and pains which cause the whole body to ache,
    particularly the joints. (In the case of the common cold, aching is
    mild and usually confined to the legs.) 
  • Fatigue. 
  • Cough and an extremely sore throat. (The common cold involves a
    less severe, “scratchy” throat.)
  • Headache which is usually severe. (Minor headache is associated
    with the common cold.).
     
Influenza usually lasts for 1-2 weeks, with chest problems
being common. In contrast, people usually recover quite quickly
from the common cold.
Complications of Influenza include pneumonia, sinusitis,
bronchitis and otitis media in children.
SYMPTOMS IN CHILDREN
It is advisable that parents of sick children should seek
medical attention early if children have respiratory illness such
as cough or difficulty breathing with fever and lethargy.
TREATMENT OPTIONS
Always consult your Doctor for diagnosis and advice. This
information is in no way intended to replace the advice of a
medical practitioner. 
Prevention 
The Influenza Vaccine is available for high-risk persons. See
the Influenza Vaccine topic.
Treatment – Drugs 
There are drugs available from your Doctor for the treatment
of all strains of Influenza A and B. These drugs must be taken
within 48 hours of symptom onset to be effective. These drugs can
reduce the severity of symptoms by almost half and reduce secondary
complications by up to 50%.
Treatment – Other 
  • Bed rest is recommended.
  • Drink plenty of fluids.
  • Antipyretics (drugs that reduce fever)/analgesics (drugs that
    relieve pain) provide relief from fever, headache and muscle pains.
    Aspirin should not be given to children with Influenza due to the
    possible risk of developing Reye’s syndrome.
  • Decongestants can provide relief from nasal obstruction or
    catarrh.
     
Aspirin should not be given to children under 16 years of age
unless specified by a Doctor.
PREVENTION
Vaccination against Influenza is recommended for certain
groups at risk. Discuss Influenza vaccination with your Doctor and
see the Influenza Vaccine topic on the Healthpoint for more
information. Other preventative measures include; avoiding people
infected with the Flu, washing hands regularly and maintaining a
healthy lifestyle.
 
NOTE
The seasonal flu vaccine has been suspended for children 5
years of age and under. See the Influenza Vaccine Suspension topic
for further information.
VITAMINS/MINERALS/HERBS
Supplements may only be of value if dietary intake is
inadequate. 
  • Vitamin A, beta carotene, vitamin C with bioflavonoids and
    vitamin E are associated with healthy immune function. 
  • Zinc is also an important element of the immune process and is
    thought to work in conjunction with many of the vitamins mentioned
    above.
  • Selenium deficiency may cause longer and more severe influenza
    infections. 
  • Echinacea, garlic and golden seal are reputed to have
    anti-bacterial properties, along with immune enhancing
    activity. 
  • Horseradish and elecampane may assist in resolving mucus.
  • Chamomile, liquorice, yarrow, boneset, peppermint and
    elderflower are herbs which make soothing teas reputed to ease the
    symptoms of colds and flu.
