H1N1 Flu Virus (Swine Flu): Symptoms, Causes, Tests, Treatments and Prevention 

H1N1 flu is also known as Swine Flu. It is a type of viral infection. The reason it is known as “swine Flu” is because it resembles a respiratory ailment that pigs can acquire. Millions of people around the world contracted the H1N1 pandemic in 2009. Today, an annual flu shot can protect you from H1N1. Rest, fluids and antiviral drugs can be used to treat it.

What is Swine Flu (H1N1)?

H1N1 influenza, sometimes referred to as swine flu, is an infectious respiratory disease brought on by a particular strain of the influenza A virus. Although it now transmits from person to person, the reason this virus is known as ‘Swine Flu’ is because it first infected pigs before moving on to humans. Although swine Flu still circulates seasonally, it originally attracted notice during the 2009 epidemic.

What are The Symptoms of Swine Flu?

The symptoms of Swine Flu (H1N1) are related to the symptoms of regular Flu. The symptoms could appear three to five days after being exposed to the virus. Symptoms may include: 

• Fever
• Cough
• Sore throat
• Chills
• Headache
• Body or muscle aches
• fatigue

Symptoms in children and babies may be different. If they exhibit any of the following signs, make an immediate call to their healthcare provider right away:

• Trouble waking up
• Not drinking enough fluids
• Trouble breathing
• Confusion
• Fever with rash.

 Unlike the regular Flu, Swine Flu can lead to more serious problems including a lung infection, pneumonia and other breathing problems. Additionally, it may exacerbate conditions like diabetes or asthma. If you have symptoms like severe vomiting, shortness of breath, dizziness, confusion or pain in your belly or sides, then contact with   Singh provides you with guidance and valuable information on how to stay safe and protect yourself from this contagious virus. She emphasized the value of becoming vaccinated, practicing proper hygiene such as frequent handwashing and using masks when in confined or congested areas.

What Causes Swine Flu (H1N1)?

A virus causes Swine Flu (H1N1). It spreads from one person to another person. Influenza viruses such as H1N1 infect the cells that line your throat, lungs and nose. When a person sneezes or coughs, droplets go into the air. When you inhale (breathe in) the virus, you can contract the infection. When you touch a contaminated surface and subsequently touch your lips, nose, or eyes, the infection may also spread. People who have the virus are probably contagious from about a day before symptoms develop to approximately four days after they begin. People and children with weakened immune systems may be able to spread the virus for a slightly longer time.

Tests of Swine Flu

Testing for Swine Flu also known as H1N1 Influenza, typically involves a respiratory sample such as a throat Swab or Nasal Swab, collected from the patient. The sample will be sent to a lab for evaluation. Your doctor uses a larger Swab than the ones in your restroom to examine the back of your throat, inside of your nose, and other areas to check for the swine flu. But the test isn’t as widespread as those for regular Flu. Therefore, the only individuals who need to be tested are those who are hospitalized or who are at high risk for developing serious health issues from the swine flu, such as: 

• People 65 or older
• Children under 5 years old
• Pregnant women
• Children and teenagers (under the age of 18) who are taking aspirin for a prolonged period and who may be at risk for Reye’s syndrome after contracting the swine flu
• People in nursing homes and other long-term care facilities
• Children and adults with chronic heart, lung, blood, liver, nervous system, metabolic or neuromuscular problems. 

How is Swine Flu Treated?

Most people with Swine Flu (H1N1) who are healthy don’t need treatments or special drugs. If you have Swine flu, you should:

• Eat a light diet
• Drink fluids
• Get plenty of rest
• Take Acetaminophen to reduce fever and relieve pains and aches.
• Stay home

If you’re unwell or sick, Dr. Sheetu Singh may prescribe an Antiviral medicine. Antiviral drugs such as Zanamivir (Relenza®)  or Oseltamivir (Tamiflu®) can kill the virus. These drugs can diminish the time you’re sick and help ease your symptoms. Antiviral medications function best when used as soon as symptoms appear.

How is Swine Flu (H1N1) Prevented?

The yearly vaccination against influenza is the strongest defense against swine flu (H1N1). Since 2010, the Flu vaccine has helped protect against Swine Flu. Other measures to guard against catching and transmitting the H1N1 Swine Flu include: 

• Avoid people who are sick.
• Stay home if you’re sick.
• Don’t touch your nose, mouth or eyes.
• When you cough or sneeze, cover your mouth and nose with a tissue.
• Wash your hands with water or soap.
• If you don’t have a sneeze, cough or tissue into your elbow.
• Don’t share personal items such as straws, cups and utensils.
