Medical experts in Delhi warn that H1N1 and seasonal flu share overlapping symptoms, making clinical diagnosis based on fever or body aches alone unreliable.
Doctors advise monitoring for warning signs such as breathing difficulty, chest pain, reduced oxygen levels, and persistent fever beyond 72 hours, particularly in high-risk groups like the elderly or pregnant women.
Health professionals emphasize that testing is only necessary when it influences treatment choices, urging patients to avoid self-medicating with antibiotics which are ineffective against viral influenza.
