Flu cases are seeing a rapid increase in several regions globally, with rising reports of infections and higher rates of virus detection.
Health authorities are urging the public to take precautions and seek vaccinations as the risk of flu continues to grow.
Here's everything you need to know about Influenza A, its symptoms, and ways to stay protected.
What is Influenza A?
Influenza viruses are categorized into four main types: A, B, C, and D. Influenza A is a highly contagious respiratory infection caused by the A-type virus. It is one of the most common strains and affects many people each year. Unlike Influenza B, Influenza A has a broader range of natural hosts and tends to mutate more frequently, making it a primary cause of widespread flu outbreaks.
Symptoms of Influenza A
Influenza A generally causes more intense symptoms than the common cold. Individuals infected with the virus may experience high fever (over 39°C), chills, body aches, fatigue, and loss of appetite. Although these symptoms are more severe than those of a cold, the flu is typically self-limiting, meaning most people with a healthy immune system will recover in five to seven days.
However, in more serious cases, the flu can lead to complications such as viral pneumonia, secondary bacterial pneumonia, acute respiratory distress syndrome, shock, and problems with the cardiovascular or nervous systems. In severe cases, these complications can be life-threatening.
Can Oseltamivir Be Used Without a Prescription?
Oseltamivir, an antiviral medication commonly used to treat the flu, is effective against both Influenza A and B. However, it is important to note that oseltamivir does not work for the common cold and should only be used after a confirmed diagnosis of the flu. Oseltamivir is available in several forms, such as capsules, granules, and liquid suspensions, making it suitable for different age groups. Since it is a prescription medication, it should only be taken under the guidance of a healthcare provider.
What to Do if a Family Member Has the Flu
Encourage rest and isolation: Keep the sick person at home and have them rest in a separate, well-ventilated room to minimize the risk of spreading the virus.
Practice good hygiene: Ensure the infected person covers their mouth and nose when coughing or sneezing, using tissues or towels to prevent the spread of droplets.
Monitor symptoms: Pay attention to severe symptoms such as a high fever that doesn't decrease, difficulty breathing, confusion, or severe vomiting and diarrhea. If these symptoms occur, seek medical help immediately.
Designate one caregiver: A healthy family member (preferably not at high risk) should provide care for the sick person and wear a mask during close contact to reduce the chances of transmission.
Key Prevention Measures
Vaccination: The best time to receive the flu vaccine is before flu season starts. Getting vaccinated can reduce the chances of contracting the flu and prevent severe complications. Vulnerable groups, such as pregnant women, the elderly, people with chronic health conditions, children, and others at higher risk, should prioritize vaccination.
Daily protective habits:
Wash your hands frequently and practice good respiratory hygiene by covering your mouth and nose when coughing or sneezing.
Avoid crowded areas during flu season and stay away from individuals showing flu-like symptoms.
Regularly clean and disinfect surfaces that are frequently touched, such as doorknobs, light switches, and handrails.
Wear a mask in public, especially in crowded spaces, to protect yourself and others.
By following these preventive measures, you can help reduce your risk of contracting the flu and protect those around you.
