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.
Avoiding transmission of Seasonal Flu:
- Wash and dry hands consistently
- Cover your mouth and nose while sneezing or coughing
- Stay at home when you are sick
- Avoid close contact with sick people
- Avoid touching your eyes, nose, or mouth
Who is at the highest risk of seasonal flu infection?
Although everyone can get infected with seasonal flu, certain groups are at higher risk of severe disease or complications than others.
- Pregnant women
- Children under the age of five years
- Geriatric population
- Individuals with chronic cardiac, pulmonary, renal, metabolic, neurodevelopmental, liver, or hematologic diseases
- Immunosuppressive conditions like HIV, chemotherapy, steroids, or malignancy
- Healthcare workers with constant contact with the infected patients
What is the treatment for influenza flu infection?
People suffering from mild episodes of seasonal flu recover on their own. However, ones with severe and long-lasting symptoms or other medical conditions should visit their doctor immediately. They get treatment with suitable anti-viral medications as required.
Tips to cure mild symptoms
- Rest
- Drink lots of fluids
- Treat other symptoms such as fever
- Seek medical attention immediately if symptoms get worse
How to avoid Seasonal Flu Infection?
Attaining immunity against influenza viruses is the best way to avoid seasonal flu infections. Hence, vaccination is one of the safest, easiest, and most effective methods. Immunity through vaccination diminishes with time, so WHO and CDC recommend annual flu vaccination against seasonal flu infection.
Annual flu shots are recommended for:
- Children aged 6 months and above
- Old age people over 65 years
- Pregnant women and health workers
- Individuals with chronic health complications like diabetes and heart conditions
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.
