Whenever the weather shifts, a sudden surge in common cold, cough, and viral fever cases is observed across hospitals and clinics. Many people wonder whether the drop in temperature or cold breeze is directly responsible for making them sick. However, medical professionals clarify that the transition in weather primarily acts as a catalyst rather than the direct root cause of these illnesses.
According to Dr. Brunda M S, Senior Consultant in Internal Medicine at Aster CMI Hospital, Bengaluru, respiratory viruses such as rhinovirus are the actual culprits behind seasonal colds. When temperatures fluctuate, particularly after rainy spells, these pathogens find favorable environments to survive and multiply, leading to widespread infections among vulnerable populations.
Furthermore, lifestyle changes during weather transitions play a major role in disease transmission. People tend to spend more time indoors in closed, poorly ventilated spaces, bringing them into closer contact with one another. This makes it significantly easier for airborne droplets and contaminated surfaces to transmit viruses from an infected individual to healthy persons, underscoring the importance of proper hygiene and preventive care.
