Seasonal Influenza: Types, Symptoms, Causes & Treatment

Are you feeling run down and experiencing flu-like symptoms? It might not just be the common cold after all. It could be seasonal influenza. Influenza, commonly called the flu, is a highly infectious respiratory illness. 

Every year, countless people fall victim to this debilitating disease, leading to missed work and school and disrupted daily activities. 

In today’s blog, we will discuss the different types of seasonal influenza, common symptoms to look out for, the causes of the flu, and the best ways for its prevention and treatment. Get ready to arm yourself with the latest knowledge on seasonal influenza and protect yourself and your loved ones from its grasp.

What is Seasonal Influenza?

Seasonal influenza also called the flu, is a highly contagious disease caused by the influenza virus. It is a common illness that affects millions of people worldwide each year, especially during the flu season, like the fall and winter months. 

The flu is spread through respiratory droplets by an infected person when he/she sneezes, coughs, or talks. It is most common during the winter, hence the name “seasonal” influenza.

You must keep in mind that you may exhibit common cold flu symptoms like chills, fever, cough, etc. However, influenza is different from the common cold. These symptoms can last several days to a week and can be severe, making it difficult to carry out daily activities.

What are the Types of Seasonal Influenza?

There are four main types of seasonal influenza viruses: A, B, C, and D.

1. 1. Influenza A: This type of influenza is the most common and often causes severe outbreaks. Influenza A viruses are constantly evolving and can be found in different animals, including birds and mammals, which makes it easier for the virus to jump from animals to humans and cause pandemics.
   2. Influenza B: Influenza B viruses are less common than type A, but they can still cause serious outbreaks, especially among children and young adults. Influenza B viruses do not cause pandemics and tend to cause milder symptoms than type A viruses.
   3. Influenza C: Influenza C is a milder form of the flu and is typically less severe than types A and B. Influenza C is not a major cause of widespread outbreaks and is not typically included in seasonal flu vaccines.
   4. Influenza D: Influenza D is an influenza type that primarily affects cattle and is not known to cause illness in humans.

It’s important to note that while the flu viruses are always changing, the seasonal flu vaccine is updated every year to protect against the flu strains that are most likely to be circulating. If you suspect you have an influenza infection, it’s best to see a healthcare provider for a proper diagnosis and treatment plan.

What are the Symptoms of Seasonal Influenza?

• Fever: A high temperature that can range from mild to severe.
• Chills: An intense sensation of coldness accompanied by shivering.
• Cough: A persistent cough that can produce mucus or phlegm.
• Sore Throat: A painful or scratchy feeling in the throat.
• Runny or Stuffy Nose: A congested or runny nose that can be accompanied by sneezing.
• Muscle or Body Aches: Pain and stiffness in the muscles, especially in the back, arms, legs, and joints.
• Headache: A throbbing or dull pain in the head.
• Fatigue: Excessive tiredness and weakness that can last several days to a week.
• Nausea and Vomiting: Uneasiness and discomfort in the stomach that can lead to vomiting.
• Diarrhoea: Loose, watery stools that can be accompanied by abdominal pain and cramping.

It’s important to note that not every infected person will have all these symptoms, and some people may experience mild flu signs and symptoms. Furthermore, some people may develop other conditions, such as sinus and ear infections. This necessitates a visit to the best ENT hospital in your region.

An infected person may also struggle with the following symptoms of influenza:

• Shortness of breath
• Eye pain
• Loss of smell and/or taste
• Chest discomfort
• Extreme exhaustion

These symptoms can develop suddenly and last several days to a week or more. The flu can also lead to severe complications such as pneumonia and bronchitis. In such cases, you must consult an expert chest specialist doctor to prevent any further harm. 

What are the Causes of Seasonal Influenza?

Influenza causes are attributed to the highly contagious influenza virus that spreads through respiratory droplets or contaminated surfaces. It gets transmitted from person to person when an infected person talks, coughs, or sneezes. The flu can also be spread by touching a contaminated thing, object or surface and then touching the mouth, nose, or eyes.

Influenza disease is caused by different strains of the influenza virus, which often result in outbreaks and epidemics. The flu viruses can evolve and change from year to year, which is why it’s important to get a flu vaccine shot every year to help protect against the most common strains.

There are certain groups of individuals who are most at risk of getting the flu. Seasonal influenza symptoms are mostly seen in:

• Children under 5
• Older adults, especially those over the age of 65
• Pregnant women
• Individuals with weakened immune systems
• People who live or work in close quarters, such as schools, nursing homes, or military barracks.
• Obese people or individuals with a BMI (Body Mass Index) of 40 or more.
• People with COPD, asthma or any chronic lung disease.

Factors that increase the risk of getting the flu include close contact with someone who is infected, poor hand hygiene, and not getting a flu shot. Taking preventative measures, such as getting the flu shot, washing your hands frequently, and avoiding close contact with people who are sick, can help reduce the risk of getting the flu.

What is the Treatment for Seasonal Influenza?

Influenza treatment involves relieving symptoms and preventing complications.

Here are some of the treatments for seasonal influenza:

• Antiviral Medications: Antiviral drugs can help reduce the severity and duration of flu symptoms and prevent serious complications. They work by slowing the replication of the flu virus, which can help reduce the severity of symptoms and the risk of complications. These drugs are most effective when started within 48 hours of the onset of symptoms but can still be beneficial when started later.
• Pain Relievers: Over-the-counter pain relievers can help relieve headaches, muscle aches, and fever.
• Hydration: Staying hydrated is essential, especially if you have a fever, as it can help prevent dehydration and relieve symptoms. Drinking plenty of fluids, such as water, electrolyte-rich sports drinks, and clear broths, can help.
• Rest: Getting plenty of rest is important for recovery, as it can help conserve energy and allow your body to focus on fighting the infection.
• Humidifier: Using a humidifier can help relieve stuffy nose and throat symptoms.

A doctor will evaluate your influenza symptoms and treatment plan will be prescribed as per your unique situation. 

In numerous cases, influenza supportive therapy alone can relieve symptoms and support the body’s natural healing processes rather than directly attacking the virus. In severe cases, hospitalisation may be necessary, especially for people who are at high risk of serious complications, such as older adults, young children, and people with chronic health conditions. Treatment in the hospital may include intravenous fluids, oxygen therapy, and supportive care to help manage symptoms and prevent complications.

How to Prevent Seasonal Influenza?

Prevention of influenza is essential for maintaining good health and reducing the spread of the virus to others. There are multiple simple steps you can take to diminish your risk of getting the flu, including:

• Get Vaccinated: A great way to prevent seasonal influenza is to get jabbed every year. Flu vaccines are safe, effective, and widely available, and they can help protect you from getting sick and reduce the severity of symptoms if you do get sick.
• Wash Your Hands: Regular handwashing is a simple yet effective method to prevent the spread of flu and other infections. Just ensure to wash your hands frequently with water and soap, especially after blowing your nose and using the bathroom.
• Cover Your Mouth: After all, you do not want to cough directly at someone’s face! You must cover your mouth and nose with a handkerchief or tissue when you cough or sneeze.
• Stay Home When Sick: If you’re sick with the flu or flu-like symptoms, stay home and avoid contact with others to prevent the spread of the virus.
• Clean Surfaces: Clean and disinfect frequently-touched surfaces, such as doorknobs, light switches, and keyboards, to control the spreading of microbes.
• Avoid Close Contact: Avoid coming in close contact with people who are sick, and take steps to protect yourself if you must be around someone with the flu.
