Why influenza fatigue lasts for weeks: Doctor's tips

With the onset of the monsoon season, influenza cases have risen significantly in Kerala. Influenza is a highly contagious viral infection that primarily targets the respiratory system, including the nose, throat, and lungs. While it is commonly associated with a high fever, many patients also suffer from headaches, sore throats, severe body aches, and vomiting. Dr Jyothish Raj, General Medicine Consultant at the Mar Sleeva Medicity, Palai, explains. 

Understanding transmission and recovery
The influenza virus spreads effortlessly through respiratory droplets when an infected person breathes, coughs, or sneezes. It can also be contracted by touching contaminated surfaces and subsequently touching the mouth, nose, or eyes. Although most individuals recover from the acute symptoms within five to seven days, post-viral fatigue and a mild cough can linger for up to two weeks. For those with pre-existing health conditions, prioritising rest and clinical consultation is critical. Receiving an annual influenza vaccine remains the most effective preventive measure to lower the risk of infection and reduce its severity.

When to seek urgent medical attention
While influenza affects all age groups, certain red-flag symptoms warrant immediate medical attention. If you experience shortness of breath, breathing difficulties, chest pain, persistent pressure, sudden dizziness, or uncontrollable vomiting, you must seek professional care. The infection can escalate rapidly, particularly in those with weakened immune systems, leading to severe complications such as pneumonia, bronchitis, acute asthma flare-ups, cardiac complications, and acute respiratory distress syndrome (ARDS).

Effective management and recovery tips
Administering antiviral medication within the first 48 hours of symptom onset is highly effective in shortening the duration of the illness and preventing secondary complications. Alongside medical treatment, getting plenty of rest is absolutely essential. Patients should drink plenty of warm water and opt for light, nutrient-dense meals to sustain their electrolyte balance. Getting sufficient, uninterrupted sleep is also crucial for restoring energy levels and boosting the body's natural immune defences.
