Title: Influenza: Symptoms, causes, treatment and prevention


1
INFLUENZA
  • SYMPTOMS CAUSES TREATMENT PREVENTION

2
INTRODUCTION TO INFLUENZA
  • The flu is a contagious respiratory illness
    caused by influenza viruses that infect the nose,
    throat, and lungs. It can cause mild to severe
    illness, and at times can lead to death. The best
    way to prevent the flu is by getting a flu
    vaccine each year.
  • How flu spread
  • Most experts believe that flr viruses spres
    mainly by droplets made when people with flu
    cough, sneeze or talk. These droplets can land in
    the mouths or noses of people who are nearby.
    Less often, a person might also get flu by
    touching a surface or object that has flu virus
    on it and then touching their own mouth, eyes or
    possibly their nose.

SYMPTOMS OF INFLUENZA
  • Moderate to high fever
  • Dry cough
  • Headache
  • Sore throat
  • Chills
  • Runny nose
  • Loss of appetite
  • Muscle aches
  • Tiredness

4
DIFFERENCE BETWEEN A COMMON COLD AND INFLUENZA
  • Many cold and influenza symptoms are similar.
    Both common cold and influenza are caused by
    viruses. There are some differences with
    influenza. Symptoms of influenza often hit
    suddenly and cause you to become weaker and
    weaker. The dry cough and fatigue of influenza
    can last two to three weeks. Signs that
    influenza is getting worse include
  • Fever
  • Shaking chills
  • Shortness of breath
  • If you think that your illness is getting worse,
    contact your pulmonologist promptly.

5
TREATMENT OF INFLUENZA
  • Most people with influenza who are otherwise
    healthy do not need special drugs or treatments.
    If you have influenza, you should Rest
  • Drink lots of fluids
  • Eat a light diet
  • Stay at home
  • Take appropriate medicines
  • Antiviral medication
  • Antiviral drugs
  • Antiviral treatment last for 3-5 days and must be
    started with in the first 2 days of illness.

6
MEDICINES FOR SEVERE INFLUENZA CASES
  • If you are seriously ill, your health care
    provider might order an antiviral drug for you.
    Infections from bacteria are more likely when you
    have influenza. Health care providers treat these
    bacterial infections with antibiotic drugs.
    Common secondary infections include 
  • Bacterial pneumonia
  • Ear infections
  • Sinus infections

7
Prevention of influenza
  • If you receive an influenza vaccine, you are
    likely to be protected from influenza. The
    vaccine is given as a shot or a nasal spray. You
    must get the vaccine every year to be protected.
    Sometimes the vaccine does not prevent influenza
    but makes its symptoms less severe. The vaccine
    is safe, even for pregnant women. You cannot get
    influenza from the vaccine.

WHO SHOULD RECEIVE THE VACCINATION?
  • Its a good idea for everyone to get an influenza
    vaccine every year. You will protect yourself and
    other people. People who have a high risk of
    becoming seriously ill from influenza are urged
    to get a vaccine once a year. You should also ask
    your pulmonologist about a pneumonia vaccination.
    You have a high risk if you have 
  • Lung disease
  • Kidney disease
  • Diabetes
  • Heart problems
  • An illness or are taking a medicine that makes it
    hard for your body to fight illnesses
  • Severe anaemia

CONTINUE.
  • You also have a higher risk of becoming seriously
    ill if you 
  • Are over 65 years old
  • Are under 18 years old and must
    take aspirin regularly
  • Live or work in a nursing home
  • Have AIDS
  • Other individuals who are not at high risk might
    also receive a flu vaccination. If you work in a
    healthcare facility, you may transmit influenza
    to others in a healthcare facility, but you are
    not at a higher risk of becoming seriously ill.
