Influenza A virus (nasopharyngeal swab, lavage)

Influenza A is a virus that can cause serious respiratory infections in humans. Timely detection and appropriate treatment can help prevent more severe cases and limit the spread of the disease. The Influenza A virus test (nasopharyngeal swab, lavage) at IntroLab offers fast and accurate results for identifying the virus.

What is the Influenza A virus?

The Influenza A virus belongs to the Orthomyxoviridae family and has multiple subtypes based on its protein composition, specifically the combinations of hemagglutinin (H) and neuraminidase (N). These variations make the virus highly adaptable and capable of crossing between different host species, including birds, pigs, and humans. The existence of different Influenza A virus subtypes in various host species contributes to its potential to cause pandemics.

What are the symptoms?

Symptoms of the infection include:

• High fever
• Cough
• Sore throat
• Runny nose
• Headache
• Muscle pain
• Fatigue

Symptoms typically appear suddenly and can vary in severity.

How is the virus transmitted?

Influenza A is spread through respiratory droplets from coughing or sneezing, as well as through direct contact with infected individuals or contaminated surfaces.

How to protect yourself?

The most effective protection against the Influenza A virus is vaccination. Additionally, it’s recommended to regularly wash your hands with soap, wear masks in enclosed spaces, and avoid close contact with individuals showing flu symptoms.

When and why is Influenza A virus testing (nasopharyngeal swab, lavage) performed?

Testing is advised when there is suspicion of infection, particularly during seasonal flu outbreaks or in the case of a pandemic.

Early detection is critical not only for providing appropriate treatment for the individual but also for preventing the spread of the virus in the community. Rapid diagnosis helps doctors choose the most effective treatment and take necessary steps to isolate infected individuals, reducing the risk of further transmission.

This test is especially recommended for people with chronic conditions, the elderly, children, pregnant women, and healthcare workers, as well as others at higher risk of infection.
