What Is Swine Flu Or Swine Influenza?

In 2009, a viral and respiratory disease became the top news as it spread quickly, affecting millions of people worldwide. It was H1N1 swine flu, caused by the subtype of influenza A virus that specifically infects the host's upper and lower respiratory tracts. While influenza viruses affect a wide range of species, from humans to pigs, a phenomenon called ‘antigenic shift’ resulted in the development of a deadly variant of influenza A due to triple genetic reassortment between bird, swine, and human flu viruses

The H1N1 virus was first isolated from pigs in the 1930s by researchers in the United States and was later recognised as the cause of flu infections worldwide. It results in symptoms like fever, nasal secretion, chills and respiratory infections. After this, it became a predominant swine influenza strain infecting millions of individuals, especially those closely associated with pigs.

What Are Swine Influenza Causes?

Swine flu is a viral disease generally caused by the transmission of the H1N1 virus via droplets or close contact. There are various Swine influenza virus strains, including:

• Influenza C

• Subtypes of Influenza A: H1N1, H1N2, H2N1, H3N1, H3N2 and H2N3.

  
  

When these viruses enter the host's body, they damage the cells that protect the nose, throat, and lungs. It can be spread via droplets of the infected person or the touching of your eyes or nose after contact with the contaminated surfaces.

Who All Are At The Risk Of Swine Influenza Virus?

It is important to know the risk factors of swine flu plus who are more likely to catch H1N1 flu:

1. Age Factor: Children under age 5 and adults older than 65 are more prone to the H1N1 flu.

2. Individuals with Weak immune systems: Immunity protects the body from infections. Still, people who have undergone organ transplantation, cancer treatments or blood cancer have weak immune systems, allowing the flu virus to invade and develop complications.

3. Individuals Dealing with chronic diseases: These include disorders like diabetes, asthma, cardiovascular disease, nervous system disease, etc.

4. Pregnancy or Nursing Women: They are more likely to develop H1N1 influenza symptoms, so they must take extra care while travelling or going outside.

How Do You Prevent Swine Influenza (H1N1)?

To prevent swine flu (H1N1), you can take the following measures:

1. Vaccination

The effective vaccine for swine influenza is a flu shot or flu vaccine. It is very important to take the complete vaccination dose to reduce the risk of infection. For swine flu, the Centers for Disease Control and Prevention (CDC) recommends annual flu vaccination for everyone 6 months or older. 

2. Take Proper Sanitisation

Always wash your hands with soap and water after touching the infected surfaces like door handles, tables, vehicle handles, workplace items, etc.

3. Cover Your Mouth While Coughing Or Sneezing

The most important prevention method is covering your mouth while sneezing or coughing. As you sneeze or cough, the tiny droplets can transmit via air and infect the people around you, thus further spreading the infection. Always carry a handkerchief or small towel with you and use it while coughing or sneezing. 

4. Isolation

It is another great method to reduce the chances of infection. If you are dealing with the symptoms of swine flu (H1N1), try to avoid social gatherings or unnecessary crowds. 

5. Avoid Sharing Personal Belongings 

It is essential not to share your personal stuff like towels, comb, soap, and utensils with anyone as it may increase the risk of spreading of H1N1 virus.

Understanding Swine Influenza Treatments 

Well, vaccination can help to prevent the risk of swine flu, but you can also go for H1N1 treatment options like:

1. Rest: Take proper rest as it improves the functioning of the cells and recharges your immunity to fight the pathogens.

2. Drink plenty of fluids: To deal with viruses, it is important to remain hydrated and immune. You can drink water or infuse it with herbs like ginger and tulsi or simply add immune-boosting drinks to your diet.

3. Eat Nutritious Food: Stick to a balanced diet as the nutrients (vitamins and minerals) can help to improve the immune system.

4. Medications: Your doctor may prescribe some anti-viral medications like oseltamivir (Tamiflu®) or zanamivir (Relenza®).  Do not take these medicines by yourself.
