Common Early Symptoms of H3N2 Influenza in Pakistan:

1.     Sudden Fever and Chills – Patients often experience a rapid increase in body temperature, shivering, profuse sweating, and extreme weakness. High fever may persist for several days, requiring immediate medical attention.

2.     Persistent Cough and Sore Throat – A dry cough can worsen over time, and severe throat pain may make speaking difficult. Health authorities recommend wearing masks and following preventive hygiene practices.

3.     Runny or Blocked Nose – H3N2 affects the upper respiratory system, causing nasal congestion, frequent sneezing, and a runny or blocked nose, similar to seasonal flu.

4.     Body Aches and Fatigue – Muscle and joint pain, headaches, and fatigue are common, often making daily activities difficult for patients.

5.     Vomiting or Diarrhea – While primarily a respiratory illness, H3N2 can affect the digestive system, particularly in children, leading to dehydration, weakness, and reduced appetite.

Expert Advice:
Medical professionals in Pakistan stress avoiding self-medication. Anyone showing these symptoms should seek medical attention immediately. Strict adherence to hygiene measures, mask-wearing, and social distancing can significantly reduce the spread of H3N2 influenza.
