Changing temperatures increase cases of viral infections, allergies, warn doctors

Dr Wiqar Shaikh, internal medicine department, JJ Hospital, expressed his concerns saying, “The fluctuating temperature is posing a serious threat to public health. Our respiratory wards are witnessing a surge in patients, even with a decrease in air pollution. The fluctuating weather seems to be a significant factor in exacerbating respiratory issues and compromising individuals’ immune responses.”

Despite a noticeable decrease in air pollution, Mumbai is witnessing a sustained influx of patients with respiratory problems with the temperature variations aggravating pre-existing health conditions. According to doctors, such fluctuations in temperature can weaken the body’s defence mechanisms.

In cases of common cold, the symptoms last only for a week, while viral infections persist longer with headache, joint ache, dry cough and a low grade fever, doctors said. With bacterial infection, the sputum colour turns yellowish or greenish and is accompanied by high fever and sore throat.

“An increase in air pollution attacks the respiratory system,while higher levels of carbon monoxide directly hit the cardiovascular system and the respiratory tract, particularly among children,” said Dr Gauram Bhansali, consultant general physician at Bombay Hospital.

Adding to the worries of healthcare professionals is the emergence of the JN.1, the new Omicron variant of Covid-19. Unpredictable weather conditions in Mumbai could further facilitate the spread of the highly transmissible variant, fear experts.

Dr Rahul Pandit, chair Intensive Care Unit at HN Reliance Hospital and former member of the state Covid task force, emphasised the need for heightened vigilance.

“The Omicron variant is already presenting unique challenges, and the weather conditions in Mumbai are not helping… We need to be extra cautious and adhere to preventive measures to curb the potential impact of this variant on our healthcare system.”

Public awareness campaigns are underway to educate citizens about the correlation between temperature shifts and increased susceptibility to infections.
