Influenza, commonly known as the flu, is an infection of the respiratory tract caused by influenza viruses (such as these A/B/H1N1/H3N2). It can range from mild to severe and can increase the risk. Children, the elderly and people with weak immunity are especially susceptible to this disease.  

COVID-19 or Respiratory Syncytial Virus

There are certain early symptoms to manage influenza, reduce its spread and prevent complications. It will be mandatory for everyone to pay attention to symptoms like fever, body ache, fatigue, cough, nasal congestion and sore throat and report to a specialist without any delay. Apart from this, timely testing will also be advised. Symptoms of influenza can be similar to other respiratory infections like COVID-19 or respiratory syncytial virus (RSV) and can take a toll on the overall health of the person. Molecular testing will be a boon for patients. 

Transcription-polymerase chain reaction (RT-PCR)

Molecular tests such as reverse transcription-polymerase chain reaction (RT-PCR) are the gold standard for diagnosing influenza and initiating timely management. It helps identify the genetic material (RNA) of the influenza virus, thereby ensuring correct diagnosis. It is important not only to differentiate between influenza and its subtypes, but also to differentiate from other respiratory illnesses with similar symptoms. Get this test done as advised by the doctor and seek treatment before the condition worsens.

This helps in timely initiation of antiviral treatment, which is most effective when started within the first 2 days of the onset of worrisome symptoms such as cough and fever. Early diagnosis also helps in isolating people affected by the flu, promoting vaccination and raising awareness about preventive measures, thereby increasing awareness about the flu. By preventing the spread of the virus, experts can avoid hospitalizations during peak flu season.

 Many children and the elderly may be hospitalized due to the flu. Remember, flu cases are more common during the winter season because the weather is cold outside and people spend more time indoors. This increases the chances of the virus spreading. Prevention is important during this period. An annual flu vaccination is recommended for everyone.
