What is Influenza?
It, commonly referred to as ‘flu,’ is an influenza virus infectious disease. Mild to serious symptoms can be present. High fever, flushes in the nose, sore throat, muscle and joint pain, headache, cough and tiredness are common symptoms of this disease.
Typically, these symptoms start 2 days after viral exposure and last less than a week. The cough may be longer than two weeks, however.
Diarrhea and vomiting may occur in children, but in adults they are not common.
Gastroenteritis, an unrelated disease that is sometimes inaccurately termed “stomach flu” or “24 hr flu,” is more commonly associated with diarrhea and vomiting.
It complications can include viral pneumonia, secondary pneumonia of the bacterium, sinus infections and worsened past medical issues such as asthma or cardiac insufficiency.
Type A, Type B and Type C affect humans by three of the four types of influenza viruses. Type D is not common to human infection, but it is thought that it is potentially present in humans.
The virus normally spreads from toxins or sneezes through the air. Mostly over relatively short periods this is thought to occur.
It can also be propagated by touching viral surfaces and touching the eyes , nose or mouth. A person can have symptoms both before and during the period of infection.
The infection can be confirmed by testing the neck, sputum or virus nose. There are a number of quick tests, but people can still have the infection, although it does not work well.
More accurate is a type of polymerase chain reaction that detects the RNA of the virus.
The symptoms of influenza are given below:
i) Fever and refreshments.
ii) Too bad!
iii) Congestion of the nose.
iv) Nose runny.
v) Horny neck.
vii) Brain muscle.
x) Watering eyes, irritated.
xi) Rouge eyes, skin, mouth , throat and nose in particular.
xii) Rash of the Petechian.
xiii) In children gastrointestinal signs (may be severe in children with influenza B), including vomiting, diarrhea , and abdominal pain.
Warning Signs Of Influenza
ii) Pain in the chest.
v) Furious vomiting.
vi) Symptoms of flu which increase but then recover with high fever and severe toxicity.
viii) High rash and fever.
ix) Can not drink liquids.
The types of viruses of influenza are given below:
i) Influenza virus A. ii) Influenza virus B. iii) Influenza virus C. iv) Influenza virus D.
Mode Of Transmission Of Influenza
More than half a million viral particles can be transmitted to the close by when an infected person sneezes or coughs.
In otherwise healthy adults, shedding of the influenza virus (the time a person is infectious) increases sharply between 1/2 and 1 day following the infection, peaks on day 2 and lasts for a total average of 5 days but can last for up to 9 days.
Symptoms and viral dumping show a similar pattern, but viral dumping precedes illness one day. In those who develop symptoms of experimental infection (only 67% of healthy experimentally infected individuals).
Children are much infectious and virus shedding until two weeks from infection, just prior to developing symptoms. Viral shedding could last longer than two weeks in people who are immunocompromised.
Vaccine Of Influenza
The World Health Organisation (WHO) recommends influenza vaccines for high-risk groups such as pregnant women, children under five years old, the elderly, workers in healthcare and people who suffer from or are immunocompromised with chronic diseases, such as HIV / AIDS, asthma, diabetes.
For those who are six months old or older without contraindications, the United States Centers of Disease Control and Prevention ( CDC) recommends influenza vaccine.
In healthy adults, the level of influenza-like symptoms in a population is modestly effective.
The vaccine reduces the likelihood of it in healthy children over 2 years, whereas in children under 2 years of age it is not well studied.
In people vaccinating with chronic obstructive lung disease it is unclear whether it reduces exacerbations of asthma.
Evidence shows that many groups with immunosuppressible conditions like HIV / AIDS, cancer, and post organ transplantation are lower in influenza-like diseases.
Vaccine can reduce the risk of heart disease in people who are at high risk.
While some reviews find insufficient evidence and others find provisional evidence it was controversial whether vaccination by the health workers affected the results of patients.
Treatment For Influenza
People with it should rest, drink plenty of liquids, avoid alcohol and tobacco and, where required, take drugs such as acetaminophen (paracetamol) to relieve flu fever and muscle aches.
On the contrary, corticosteroids are not supported as further influenza therapy. To prevent infection spread it is recommended to avoid close contact with others.
Influenza-like (especially fever) children and young people with flu symptoms (especially influenza B) should avoid aspirin because it can lead to Reye’s syndrome, a rare but potentially fatal liver condition.
Antibiotics have no effect on the infection as influenza has been caused by a virus, unless secondary infections like bacterial pneumonia are prescribed.
Antiviral drugs may be effective, if administered early, but certain influenza strains can demonstrate resistance to standard antiviral medicines and are worried about the quality of the research.
An anti-viral medication should be consulted by the doctor for high-risk individuals, such as young children, pregnant women , the elderly, and those with impaired immune systems.
Those who have emergency signs should visit the emergency room immediately.
