The new H1N1 influenza virus, which was recently isolated, is a new subtype of the influenza virus that affects humans.
It contains genes from the swine, avian, and human influenza viruses in a combination that has never been seen before. It is also certain that the virus is transmitted from
human to human.
Influenza is a
respiratory illness caused by viruses of the Influenza family.
The Influenza A virus is one of the most common types and is responsible for most flu cases in humans. It can cause serious complications and spreads quickly, especially in closed spaces or areas with high population density.
Symptoms of Influenza A
The symptoms of Influenza A usually appear suddenly and include:
- Fever or chills
- Cough
- Sore throat
- Muscle aches (toothaches, headaches, muscle pains)
- Fatigue and weakness
- Nasal congestion or runny nose
- Feeling unwell
Influenza A can cause serious complications, such as pneumonia, bronchitis, or exacerbation of chronic conditions (such as asthma and heart disease).
Older adults, children, and individuals with weakened immune systems are more susceptible to severe complications.
How Many Days Does Influenza A Last?
The symptoms of Influenza A usually last
5-7 days, but fatigue, and especially coughing, may persist for a few weeks after recovery.
However, in more severe cases, you may still be contagious for a long time after the onset of symptoms. This depends on the weakness of the immune system.
Is Influenza A Contagious?
Influenza A is contagious, and its transmission occurs when
airborne particles from secretions (coughing, sneezing, talking, kissing) are released into the air and enter the mucous membranes of another person.
Transmission is also highly likely from contact with contaminated surfaces or objects, followed by contact with the face, where the virus can enter the body through the mucous membranes. A person who is infected is considered contagious from the moment they are infected and may continue to be contagious for several days after the symptoms subside.
Prevention
Prevention is the best strategy for reducing the duration and severity of Influenza A. The most effective way to prevent H1N1 and other strains of influenza is the annual flu vaccine:
Effectiveness: The vaccine is formulated each year to protect against the strains that are expected to be most common, including H1N1.
Who should be vaccinated: It is recommended for everyone, especially for children aged 6 months and older and those in high-risk age groups.
Additional preventive measures:
- Hand washing: Regular hand washing with soap and water or using hand sanitizers.
- Cover your mouth and nose: Use a tissue or your elbow to cover your mouth and nose when coughing or sneezing.
- Avoid close contact: Stay away from sick individuals and avoid close contact with others if you are sick.
Influenza A is a serious viral infection that can have significant health impacts, particularly on vulnerable groups within the population. Prevention through vaccination, good hygiene, and other protective measures is crucial to limiting the spread of the disease. Early diagnosis and appropriate treatment can reduce complications and help with faster recovery.
