What Is Flu?

Flu illness or influenza is an acute respiratory infection caused by influenza virus. It is the commonest communicable disease that affects millions of people each year. It can infect people of all ages and both genders.

Influenza viruses are of 3 types- A, B and C. Out of these, A and B types infects humans and have caused epidemics in the past.

Type-A influenza virus frequently undergoes antigenic shifts, which means that they have a tendency to alter their strains. This is the reason why we there are chances of re-infection with some another strain of influenza virus. Type B virus is an exception as it does not tend to alter it strain.

Signs and Symptoms of Flu

Respiratory infection with influenza can have the following presentation

  • Fever with chills lasting for 1-5 days
  • Generalised weakness and a feeling of discomfort
  • Aching in muscles and joints
  • A headache
  • Watery discharge from nose
  • Watering of eyes
  • A sore throat and dry cough
  • Loss of appetite with nausea, vomiting and diarrhea may also be present

Some patients do not experience fever at all, while some recover completely within a few days without any medications. In spite of having a common presentation, this illness has an unpredictable behaviour. It can affect a small group of people at a time or there can be a sudden outburst causing epidemics and pandemics. The most recent one being H1N1 (swine flu) in 2009. Incubation period is 18 to 72 hours

Spread of Flu Illness

  • Influenza viruses have been isolated from pigs, horses, dogs, poultry animals and birds which prove that they are potential reservoirs for type A viruses.
  • Humans are also known reservoirs of the virus. Influenza virus spreads more rapidly among children.
  • When an infected person cough or sneezes, the infected respiratory droplets are released which are inhaled by a healthy person causing infection.
  • It can also be spread from contaminated surfaces like tables and door knobs.
  • Overcrowding as in schools, institutions and marketplaces is a major factor which enhances the spread of infection.

Flu can have after effects like a persistent cough and prolonged weakness. Although there is definite recovery yet, it can interfere with daily routine chores of the patient.

How Can You Manage Flu At Home?

Milder, uncomplicated forms of illness can be treated at home or certain simple home remedies can reduce infectivity and give immediate relief from signs and symptoms.

  1. Warm Salt Water Gargles – This prevents secondary bacterial infection. It also relieves a sore throat.

  3. Rest – Take rest if you have flu. It is important to relax and also prevents spread of infection to other people at work or school.
  4. Steam – Inhaling steam soothes the throat and airways. If you have dry cough during flu, steam will reduce the bouts and intensity of cough. Steam works best when you have sinusitis because of flu.
  5. Vitamin C – This is an anti-oxidant and also stimulates faster recovery from colds and flu.
    Vitamin C can be taken as tablets or from natural sources like oranges, tomatoes, bell peppers, sweet potatoes and green leafy vegetables
