What is Seasonal Flu or Influenza Infection?

Seasonal Flu or Influenza is an acute respiratory tract infection caused by influenza viruses. The symptoms of seasonal flu vary from sudden onset of fever, dry cough, headache, body, muscle and joint pain, and sore throat to a runny nose. It usually cures without treatment, with most individuals recovering within a week. However, influenza is known for its severe illness in high-risk populations like children, working professionals, elderly patients, pregnant women, health workers, and patients with life-threatening medical conditions.
Differentiating influenza from the common cold is difficult as they share similar symptoms. Additionally, it is tough to detect seasonal flu infection, leading to severe infections and even hospitalization. Hence, vaccination is the best way to prevent the disease. WHO recommends annual vaccinations to prevent seasonal flu (influenza) infections.

How does Seasonal Flu Spread?

Seasonal flu is highly contagious and spreads by touching surfaces, air droplets, sneezing, talking or coughing, and contact with infected individuals. In temperate climates, seasonal flu epidemics occur, mostly during winter, whereas in tropical areas, it occurs throughout the year. The incubation period can vary from 1 to 4 days.

How to avoid Seasonal Flu Infection?

Immunity through vaccination diminishes with time, so WHO and CDC recommend annual flu vaccination against seasonal flu infection.
Annual flu shots are recommended for:

Importance of annual flu vaccination

As per recent studies, annual flu shots reduce the risk of seasonal flu infection from 40% to 60% among the overall population. Flu vaccinations are the best possible preventive intervention against Influenza B and Influenza A viruses.
Annual vaccination assists by reducing the severity of the infection and, thereby, chances of death and complications. These flu shots hold long-lasting significance for individuals with high-risk complications of influenza and its carriers.

Do flu vaccines cause any side effects?

Flu vaccine side effects are generally mild with little to no effects on the body and perish within a few days. Injectable flu shots are commonly associated with soreness, redness, swelling from the shot, headache, fever, nausea, body pain, and occasionally fainting.
As per some studies, Guillain-Barre Syndrome (GBS) cases relate to injectable flu shots. However, they are rare and discovered in 1 or 2 cases per 1 million people vaccinated. It is more common post-flu illness than after vaccination. GBS is unassociated with the nasal spray vaccine.
