Flu

Influenza, commonly known as the flu, is a viral infection that affects the upper respiratory system of humans. The upper respiratory system consists of the nose, throat, bronchi and lungs. The symptoms of flu usually last for about a week and in most cases resolves on their own. In extreme cases, influenza can have complications and prove to be deadly. Influenza is not the same as stomach flu, which is caused by viral infections to the stomach.

People at risk of contracting the flu are;

  • People with chronic ailments like asthma, cancer, diabetes, heart disease and kidney disease
  • People who are highly obese
  • People with the weak immune system
  • Children below the age of 5 years
  • Adults older than 65 years
  • Pregnant women
  • Nursing home residents or residents of other long term care facilities

People in the most risk category can have severe complications related to some underlying diseases, such as pneumonia and in some cases even death. The best defence against influenza is to take an annual vaccination. Influenza rapidly spreads across the world in seasonal epidemics and proves to be costly with the burden of medical bills, loss of productivity and costs pertaining to other health-related diseases caused by flu.

According to WHO, close to 5-15% of the population are annually affected by the upper respiratory system problems caused by influenza.

The flu is caused by disease-carrying viruses. These viruses are categorized into three groups namely A, B and C. Annual influenza that affects a majority of the masses are caused by category A and B. Type C causes less severe symptoms. Influenza A has two subtypes A(H3N2) and A(H1N1) which are important from the perspective of humans. Influenza viruses consist of protein layers known as antigens. The genetic composition of influenza viruses is such that it undergoes frequent genetic modifications and that leads to antigenic drift. This antigenic drift drives the modifications in the annual influenza vaccines.

What are the Symptoms of Flu?

Symptoms of flu may seem similar to those experienced during a cold. Running nose, sore throat, sneezing is also experienced during the flu. Unlike the cold, flu generally develops suddenly rather than slowly as in the case of cold. Symptoms of flu tend to make one feel much worse than while experiencing cold.

Common symptoms during the flu are:

  • Dry and persistent cough
  • High fever usually over 100.4F
  • High sweat and chilly feeling
  • Aching in the muscles especially those of the back, arms and legs
  • Headache
  • Fatigue and weakness
  • Sore throat
  • Nasal congestion

Most of the people experiencing flu-like symptoms can treat themselves at home. In case the symptoms persist and cause great uneasiness, it is best to get the advice of a doctor. The doctor at Apollo Kondapur may prescribe you antiviral medications to ease the symptoms.

What are the Causes of Influenza?

Influenza viruses affect a person usually when the immune system is not working actively or in the case of severe medical conditions already prevalent. The flu virus is an extremely contagious virus and affects a person when they come in contact with an infectious person or thing.

The virus is transferred through the air in the form of droplets when an infectious person sneezes, coughs or talks. You may be infected with the flu virus while inhaling or while coming in contact with substances on which the droplets have fallen. This then gets transferred to your eyes, nose and mouth. Someone suffering from flu can be infectious before the symptoms develop until seven days afterwards.

The flu spreads mostly in crowded areas. Since there is a constant antigenic shift to the influenza viruses, it is highly likely that a person can get affected by the flu virus again and again. If the body encounters similar flu as the past, the antibodies prevalent in the body prevent the infection or reduce its severity. But the body cannot protect you from the constantly modified new influenza types.

Who are at a Risk of Influenza?

  • Older adults and young children are affected the most by seasonal flu
  • Living or working conditions; conditions where there are multiple headcounts can aid in the spread of flu
  • Weak Immune system; cancer patients, HIV/AIDS patients, anti-rejection drugs can be highly prone
  • Chronic illness; people suffering from asthma, diabetes, heart disease may be at high risk
  • Pregnancy; pregnant women especially those in the second and third trimester are highly likely to get affected
  • Obesity; people with a BMI of 40 or more can easily get affected

If the person is healthy and young, the effects of the flu virus are less severe. But high-risk people like young children and older adults can develop severe complications like pneumonia, ear infections, asthma flare-ups, bronchitis and heart problems.

How to Prevent the Flu?

It is highly recommended that people undertake annual flu vaccinations to prevent from attracting the virus. This is likely to protect against the 3 to 4 flu viruses that can spread during the year.
