Influenza A is Swine flu which is also known as the H1N1 virus was declared a pandemic i.e., a disease affecting people throughout the world in 2009. Like seasonal flu, it can cause more serious health problems
To stay informed and be protected from swine flu, one should understand its origin, symptoms, preventive measures, and treatment that are discussed hereafter.
What is Swine Flu (H1N1)?
Swine Flu is a type of influenza virus that originally infected pigs. However, the strain of H1N1 gets mutated and then spreads from animals to humans through contact.
Swine Flu is caused by the Influenza A virus, which is responsible for many respiratory illnesses. This strain of influenza gained worldwide popularity in 2009; however, it remains a public health threat today.
Is Swine Flu Still a Concern?
While talking about individuals suffering from the flu, swine flu has sickened and hospitalized countless people, along with deaths, especially in children, the elderly, pregnant women, and those people with low immunity.
Although lots of people got this pandemic in 2009, this flu is still relevant today. Remaining vigilant and taking steps beforehand can lessen the burden.
Cause of swine flu
Swine flu is caused by a strain of influenza virus that usually only infects pigs. It is highly contagious and can be spread very quickly from person to person.
A simple sneeze can cause thousands of germs to spread through the air. The disease is spread through saliva and mucus particles. People may spread them by:
sneezing
- coughing
- touching a germ-covered surface and then touching their eyes or nose
- The virus can also linger on the surface of different things like table chairs, and aoroor knobs.
Swine flu the Symptoms
People with swine flu can be highly contagious a day before they have any symptoms, and as many as 7 days after they get sick whereas kids can be contagious for 10 days long too.
Most of the symptoms of swine flu are very similar to seasonal flu. They can include:
- cough
- fever
- sore throat
- stuffy or runny nose
- body aches
- headache
- Chills and
- fatigue
Moreover, it can also lead to more serious complications like pneumonia and later respiratory failure. It can worsen the conditions of diabetes, and asthma.
If there are severe symptoms like shortness of breath, severe vomiting, abdominal pain, dizziness, or confusion, an emergency with expert treatment is a must.
Risk Factors of Swine Flu
This swine flu is generally unusual because it doesn’t target the same age group as other typical flu This disease focuses on young adults. This is unusual because most other flu viruses attack those who are elderly or very young.
Some form of immunity to swine flu may exist in elder people due to previous exposures to the flu.
Some other risk factors for swine flu include the following
- compromised immune system (from a disease such as AIDS, chemotherapy, and radiotherapy taken people)
- pregnancy
- history of infections
How Does Swine Flu Spread?
Swine Flu is highly contagious and spreads through:
Respiratory droplets: When an infected person coughs or sneezes, the virus can travel through the air.
Surface contact: Touching contaminated surfaces and then touching your mouth, nose, or eyes can lead to infection.
Close contact: Being in close contact with an infected person increases the risk of transmission
Diagnosis of Influenza Swine Flu
Diagnosis of swine flu is simply done by taking the fluid sample from those with swine flu. The sample is taken as a swab from the nose or throat and then the swab will be checked as a rapid test for differentiating influenza A or B viral infection.
This is not very accurate for H1N1 then specific test for that virus is required. The turnaround time for the test is 36 hours, and by then the decision to admit the patient for care or to use anti-viral medications has already been made.
Treatment for swine flu
The CDC recommends that healthcare workers in contact with swine flu or suspected swine flu patients take precautions such as:
- wearing gloves and/or gowns
- using eye protection
- wearing face masks
- People with known cases of swine flu should be isolated to prevent the spread of H1N1.
vaccine for swine flu
- The vaccine may be given through an injection or nasal spray. The vaccine is a preventive measure.
- Side effects of the vaccine are minor and may include: fever, aches, and soreness at the injection site.
- The oral drug oseltamivir (Tamiflu) is the current recommended medication for swine flu. It’s an antiviral drug used to treat influenza infections. This drug, or sometimes zanamivir is used as treatment for people who have been exposed to swine flu in the last 48 hours, or if they’re suspected of having swine flu. These drugs aren’t used as a preventive measure for swine flu.
Preventive Measures
Keeping in mind proper diets and remaining alert is crucial in preventing swine flu:
Vaccination: Seasonal flu shots usually have coverage for the H1N1 strain. Getting vaccinated is the best solution to evade the infection.
Sensible Hygiene Habits: You should wash your hands using soap and water often, or clean them using an alcohol-based sanitizer.
Keep your distance: Do not engage with sick people. If you are sick, do not engage with people at all.
Cover Coughs and Sneezes: Try to prevent the spread of droplets by using a tissue or your elbow.
Cleansing Surfaces: Forever clean and disinfect the most touched surfaces like countertops or doorknobs from time to time.
