The flu is a highly communicable and prevalent condition brought about by the influenza virus. An individual can acquire the flu at any time of the year. Individuals of all ages can acquire the flu, but the elderly, children and those who have weakened immune systems are at high risk and likely to develop serious complications.
What are the causes?
There are various strains of the flu virus and often mutate. The flu is highly contagious and easily spreads. It spreads via coughing and sneezing as well as personal contact, saliva and touching contaminated surfaces.
What to expect with the flu?
The flu generally lasts between 4-5 days, but the symptoms can last from anywhere from 2-7 days.
Some of the symptoms of the flu strikingly resemble common cold which includes:
- Stuffed or runny nose
- Low fever
- Watery or itchy eyes
- Sore throat
Remember that the main difference between the cold and flu symptoms is their severity. When it comes to the flu, it manifests at once and disrupts with the daily routine of the individual.
The common symptoms typically include:
- Body aches
- Excessive fatigue
There is no cure for the flu. Some prescription antiviral drugs can be given to shorten the duration of the disease. Depending on the condition of the individual, the doctor will decide if these medications are necessary.
The flu shot provides protection against the flu strains believed to arise in the upcoming flu season.
