Lucknow: Patients with respiratory ailments, chronic autoimmune diseases and heart issues need to be extra cautious as high level of pollutants in air may aggravate the situation.
With Diwali around the corner, experts feel that pollution may play a contributing role in the exacerbation of pre-existing lung issues and increase the risk of respiratory tract infections that could even be fatal.
Patients with breathing problems often have hypersensitive respiratory tracts and weak lungs. Additionally, their oxygen levels remain low. Consequently, they are at a higher risk of contracting infections from viruses and bacteria during winters, with air pollution acting as a catalyst.
Former head of the respiratory medicine department at KGMU, Prof Rajendra Prasad, said: “In common lung conditions like COPD, bronchitis and asthma, damaged air sacs, collapsed tubes, and narrowed airways along with excessive mucus production cause breathlessness. This hinders the transmission of gases and makes these patients more vulnerable to infections.”
Such patients along with those experienced severe Covid-19 infections with extensive blood clotting in the lung arteries and veins, in addition to lung fibrosis, should avoid going out until the sun is up and in the late evening.
Dr Ajay Kumar from Apollo Hospital said: “These patients often suffer from hypoxemia due to their low lung capacity. Ultrafine pollutants (PM 2.5 microns) can enter the lungs during inhalation and cause further damage. They need to take extra precautions, as their oxygen levels may drop faster than those of normal patients if they become infected.”
Manodeep Sen of the microbiology department RMLIMS said air pollutants like PM 2.5 microns can combine with tiny water droplets to form an aerosol that can serve as a host for viruses and bacterial infections.

Combating lung cancer: Innovations in diagnosis and management
Lung cancer, the third most common form of cancer worldwide, is a leading cause of cancer-related deaths. It affects both smokers and non-smokers due to factors such as asbestos exposure and pollution. While most cases occur in individuals over 70, the detection rate is rising among younger people. The disease is categorized into non-small cell lung cancer (80-85% of cases), small cell lung cancer (10-15% of cases), and rare pulmonary carcinoid tumors. Symptoms include coughing, chest pain, difficulty breathing, and fatigue. Treatment options include surgery, radiotherapy, chemotherapy, targeted drug therapy, and immunotherapy.
Kids affected by respiratory viruses amid season change, some need intensive care
An increasing number of children in Kolkata, including infants less than one year old, are contracting viral respiratory tract infections, with some needing intensive care. The respiratory syncytial virus (RSV) is the main cause, along with rhino and influenza viruses. Symptoms include respiratory distress, prolonged cough, fever, rashes, and vomiting. Health experts attribute the rise in cases to the change in season and temperature fluctuations. The state health department is working to ensure proper treatment and facilities for affected children.
Mystery respiratory illness in kids baffles paediatricians
Healthcare professionals in Pune are grappling with a mystery respiratory illness affecting children. The patients exhibit flu-like symptoms but test negative for both influenza and Covid-19. Doctors suspect an undetected seasonal respiratory virus that is not picked up by PCR tests. Although the infections are not severe, they cause high fevers and anxiety, leading to increased hospitalizations. Some children are testing positive for Covid antibodies, suggesting recent infection. Cases of respiratory illnesses have surged, with the circulating strain causing more severe infections, including pneumonia and organ complications.
