Kolkata Faces Surge in Respiratory Issues Amid Temperature Changes
Rising Respiratory Complaints in Kolkata
Residents of Kolkata are experiencing an alarming increase in symptoms such as dry cough, throat irritation, and respiratory discomfort. Medical professionals are attributing this rise to a seasonal respiratory illness linked to the city's fluctuating temperatures. The city has been undergoing significant temperature variations, with warm afternoons followed by much cooler evenings. This week, the meteorological department predicts a substantial shift with incoming rains, which experts warn could exacerbate respiratory issues.
Doctors have noted a marked increase in patients visiting outpatient departments, presenting with persistent dry cough, sore throat, fatigue, and mild fever over recent weeks. Although most cases are mild, the combination of changing weather, air pollution, and viral infections has led to what many are referring to as a “dry cough epidemic.” Common viruses such as adenovirus, rhinovirus, metapneumovirus, and enterovirus primarily affect the upper respiratory tract, resulting in severe coughing.
“This is likely due to adenovirus, which impacts both children and adults. In adults, it causes inflammation in the respiratory airways, resulting in a dry cough,” stated Dr. Sayan Chakrabarty, an infectious diseases physician.
Impact of Temperature Fluctuations on Respiratory Health
Why Do Temperature Changes Trigger Respiratory Illness?
Experts explain that rapid weather changes can weaken the body's natural defenses, making individuals more susceptible to respiratory infections. Fluctuating temperatures can irritate the respiratory tract, leading to dryness and inflammation in the throat and airways. This irritation can manifest in symptoms such as:
- Persistent dry cough
- Throat irritation or scratchiness
- Mild fever
- Fatigue and tiredness
- Severe headache
Doctors emphasize that viruses causing upper respiratory tract infections (URTI) tend to spread more readily during seasonal transitions. The shift from warm to cooler temperatures can also aggravate symptoms in those with allergies, asthma, or sinus issues.
The Role of Pollution in Respiratory Issues
Pollution Exacerbates Respiratory Symptoms
In addition to weather changes, air pollution and allergens are known to worsen respiratory symptoms throughout the city. Kolkata frequently experiences poor air quality, especially during seasonal transitions. Pollutants and airborne particles can irritate the respiratory system, leading to dry cough and throat inflammation, particularly in children, the elderly, and individuals with pre-existing lung conditions.
Medical professionals also caution that dust, pollen, and environmental allergens can intensify symptoms, resulting in prolonged coughing even after the initial infection has resolved.
Duration and Management of Dry Cough
How Long Does a Dry Cough Last?
According to doctors, a viral dry cough typically lasts between 7 to 14 days, although many individuals may continue to experience symptoms for several weeks. While most cases are not severe, persistent symptoms should not be overlooked. It is essential to seek medical attention if symptoms include:
- High fever
- Severe breathing difficulty
- Chest pain
- Cough lasting longer than three weeks
These symptoms could indicate a more serious respiratory infection that requires treatment.
Protective Measures Against Respiratory Illness
Ways to Protect Yourself
To minimize the risk of respiratory illness during temperature fluctuations, consider the following precautions:
- Stay hydrated to keep the throat moist
- Avoid exposure to dust and air pollution
- Wear a mask in crowded or polluted areas
- Maintain good hand hygiene
- Ensure adequate rest and nutrition to bolster immunity
- Consume warm fluids like herbal tea, soups, and warm water
