The Flu or The Influenza, Its Symptoms, complications and Vaccination Manual
What Is The Flu?
Influenza, Common Cold or the flu is an infectious disease of the respiratory tract due to infection with influenza viruses.
Influenza infections range from mild to severe and sometimes fatal.
The best way to prevent influenza is by taking the vaccine every year.
The CDC Centers of Diseases Control and Prevention and i quote from thir official website says that:
“There are four types of influenza viruses:
A, B, C and D.
- Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States.
- The emergence of a new and very different influenza A virus to infect people can cause an influenza pandemic.
- Influenza type C infections generally cause a mild respiratory illness and are not thought to cause epidemics.
- Influenza D viruses primarily affect cattle and are not known to infect or cause illness in people.”
8 Common Symptoms of influenza
A person with flu usually has some or all of the following symptoms:
- Fever or high temperature
- Sore throat
- Runny nose or nasal congestion
- Body and muscle aches
- Feeling tired and fatigue
- Vomiting and diarrhea in some people, especially in children
* It Is Necessary To Note That Fever May Not Appear In All Infected.
How does Influenza spread?
- Many experts believe that the spread of influenza can be caused by spray droplets when coughing, sneezing or talking.
These granules may settle in the mouth or nose of people close to the infected person.
- In some cases, infection may occur by touching surfaces or objects contaminated with the flu virus and then touching the eyes, mouth or nose.
What Is The Incubation Period of The Flu?
Incubation Period is Time Period between actually getting infected with the virus and it’s active and Someone Else Can Be Infected but the symptoms did not appear already.
Infection can be transmitted even before the onset of flu symptoms and also when the symptoms appear.
- The time range from one day before the onset of symptoms to 5-7 days after the onset of symptoms.
- Transfection may take longer to occur in children and people with immunosuppression.
Is The Seasonal Flu A Serious Disease?
Influenza varies from season to season and can not be predicted how severe will it be.
This depends on several factors including:
- Type of virus.
- The amount of pollen vaccine available.
- When the vaccine is available.
- Number of people who received the vaccine.
- Match the vaccine available with the influenza virus.
- There are some people who are more prone to complications of influenza,
- Young children
- pregnant women
- People suffering from some chronic diseases (asthma, diabetes and heart disease)
In 2009 and 2010, a new influenza virus has appeared and was dubbed H1N1 2009.
The world was hit by the first global pandemic in the last 40 years.
90% deaths were in the under-65 age group compared to seasonal flu,
where deaths are usually in those over the age of 65.
What are the 5 complications of influenza?
Influenza can cause the following complications:
- Bacterial bacterial infection.
- Ear infections.
- Sinus infections.
- Dehydration (fluid loss).
- Chronic disease exacerbation (congestive heart failure, asthma and diabetes, etc..).
Prevention Against Seasonal Influenza
The best and the most effective way to prevent influenza is to get the flu vaccine every year.
Injectable influenza vaccine:
An inactivated vaccine containing an the inactive flu virus
And is given through injection.
This vaccine has been approved to be given to people aged 6 months and older,
including healthy adults, pregnant women and people with chronic health problems.
Antibodies are produced.
Two weeks later, the immune system will be protected against the seasonal influenza virus,
However it does not prevent infection with microbes that cause an influenza-like illness.
The seasonal flu vaccine protects against influenza viruses that research has proven to be the most common.
When You Should Take The Flu Vaccine?
The vaccine is usually taken in September or when it is available,
and lasts until the end of winter.
Winter is usually the beginning of the month of October but the flu virus activates in January.
Who Should Take The FLu Vaccination?
The vaccine should be given to everyone,
but it is important that the vaccine be given to the prone to complications that may accompany the flu.
Who Is Most Susceptible To Complications Associated With Influenza?
- Children under 5 years of age, especially those younger than two years.
- Adults over the age of 65.
- pregnant women.
- People suffering from chronic illness, for example:
- Asthma (even if the condition is stable or simple)
- Chronic lung diseases (chronic obstructive pulmonary disease and cystic fibrosis)
- Heart disease (congenital heart defects and congestive heart failure and coronary artery disease)
- Diseases of the blood (sickle cell disease sickle cell disease)
- Endocrine diseases (diabetes)
- Kidney disease
- Liver diseases
- Weakness of the immune system as a result of certain diseases or medical drugs (HIV, AIDS, cancer, or steroids consumption)
- Obese people (BMI 30 or more)
Who Are The Other Categories That Should Be Vaccinated?
The following categories are considered important for vaccination and include:
- People living in nursing homes or care places for a long period of time.
- People who take care of or live with people most susceptible to complications of influenza, including:
- Health workers
- Or those who care for children under the age of 6 years,
(these children have a more severe influenza complication and can not take the vaccine for their young age)
Who Should NOT Take The Flu Vaccine?
There are some people who are given the vaccine only after consultation with the doctor and these are:
- Who are highly sensitive to eggs.
- People who should previous sensitive reactions to the flu vaccine in earlier years.
- Of those who had Guillian-Barre Syndrome (GBS) after a previous flu vaccination.
- Children under the age of 6 months (vaccination was not approved for this category).
- People who feel a moderate or high temperature and can take the vaccination after they have dealt with their high temperature and only when it’s back to its normal levels again.
