Gurgaon, one of India’s most rapidly growing cities, is facing a growing health concern due to its deteriorating air quality. With an alarming rise in pollution levels, there has been a notable increase in cases of pneumonia-like symptoms among its residents. However, these cases do not present with the typical signs of infection. Experts have linked this rise in pneumonia cases to the city’s polluted air, which is contributing to atypical forms of pneumonia, especially among those exposed to prolonged pollution.
What is Pollution-Related Pneumonia?
Pollution-related pneumonia is different from pneumonia caused by bacteria, viruses, or fungi. While pneumonia is generally caused by infections that affect the lungs, pollution-related pneumonia occurs when harmful air pollutants, such as particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2), irritate and inflame the lungs. This long exposure to pollution compromises the respiratory system, making it more vulnerable to infections and inflammation.
In some cases, the airborne pollutants can also carry pathogens like bacteria or viruses, which can directly affect the lungs. When combined with environmental pollutants, the risk of developing pneumonia or other respiratory conditions increases significantly.
Pollution-related pneumonia is becoming more common in cities like Gurgaon, where high levels of pollutants contribute to respiratory conditions among residents. The combination of poor air quality and existing health conditions can lead to more severe symptoms and complications in some individuals.
What is Walking Pneumonia?
Walking pneumonia is a milder and more atypical form of pneumonia, which has been increasingly reported in Gurgaon. Unlike conventional pneumonia, which can result in severe symptoms such as high fever and breathlessness, walking pneumonia typically causes milder symptoms that resemble the common flu. This form of pneumonia leads to inflammation in the airways and mucus buildup in the air sacs of the lungs, which can cause coughing, chest pain, and difficulty breathing.
Walking pneumonia is most commonly observed in children between the ages of 5 and 15, as well as young adults under the age of 40. Unlike more severe forms of pneumonia, people with walking pneumonia may not feel the need to rest in bed and can usually continue their daily activities, despite feeling unwell.
The condition is also associated with a specific pathogen known as Mycoplasma pneumoniae, which is often referred to as the "walking pneumonia bacteria." However, Dr. Saurabh Jindal, an internal medicine doctor in Gurgaon at Miracles Apollo Cradle/Spectra, emphasizes that walking pneumonia is not always caused by a pathogen. “Continuous exposure to polluted air weakens the lungs, making them more prone to both infectious and non-infectious inflammation." It is important to diagnose the condition early to prevent complications,” he explains.
Role of Pollution in Respiratory Health
The rapid increase in air pollution in Gurgaon plays a significant role in the rise of respiratory illnesses, including pollution-related pneumonia and walking pneumonia. The presence of fine particulate matter (PM2.5), which is small enough to enter the lungs and even the bloodstream, is one of the major pollutants in the city’s air. Prolonged inhalation of such particles can cause long-term damage to lung tissue and impair the body's immune system. This makes individuals more prone to respiratory infections, including pneumonia.
In addition to particulate matter, other pollutants like nitrogen dioxide (NO2) and sulfur dioxide (SO2) contribute to air quality degradation. A study revealed that prolonged exposure to high levels of nitrogen dioxide and fine particulate matter can double the risk of developing pneumonia over time.
Symptoms of Pollution-Related Pneumonia
Pollution-related pneumonia, including walking pneumonia, usually presents with symptoms that can be easily mistaken for a common cold or flu. These symptoms may include:
A cough that persists for more than seven days.
Chest pain or tightness
Low-grade fever, usually below 101°F
Sore throat, especially in the morning or after prolonged exposure to pollution
Weakness and fatigue, make daily tasks harder
Chills, especially during the night
Sneezing and headaches, which are common during seasonal changes or when pollution levels are high.
While these symptoms might seem mild initially, it is important not to ignore them, as they can increase over time and lead to more severe respiratory issues if left untreated.
Diagnosing Pollution-Related Pneumonia
Pollution-related pneumonia and walking pneumonia may not always be immediately apparent during a clinical examination. Diagnosing the condition may involve:
Chest X-rays to detect any signs of inflammation in the lungs or airways.
Blood tests to check for infections or abnormalities in the immune system.
Mucus samples can be analyzed to identify any pathogens present in the respiratory system.
Early detection of walking pneumonia or pollution-induced pneumonia is essential, as it can prevent the condition from progressing into more severe forms of pneumonia or other long-term respiratory issues.
Treatment and Management of Pollution-Induced Pneumonia
Treatment for pneumonia varies depending on its underlying cause. For bacterial infections, antibiotics are typically prescribed. However, for viral infections, treatment is usually symptomatic, and the condition tends to resolve on its own. In the case of pollution-induced inflammation, anti-inflammatory medications and oxygen therapy may be necessary in severe cases to help reduce swelling and support lung function.
Dr. Saurabh Jindal stresses the importance of timely intervention, stating, “If symptoms continue or worsen, consult a healthcare provider immediately. Early intervention can prevent severe complications, especially in high-risk individuals.”
Who is at High Risk?
Certain groups of people are more susceptible to the effects of pollution and face a higher risk of developing pollution-related pneumonia:
Individuals with asthma or chronic obstructive pulmonary disease (COPD): These conditions already compromise the lungs, making them more susceptible to inflammation and infection.
People with weakened immune systems: Individuals who are immunocompromised due to conditions such as cancer, HIV, or organ transplants are at higher risk.
Those on long-term steroid medication: Steroids suppress the immune system, leaving individuals more vulnerable to infections.
Children and the elderly: Both groups have weaker immune systems, making them more vulnerable to respiratory issues caused by pollution.
Prevention Tips
While it may be impossible to completely avoid pollution, several preventive measures can help protect yourself and your loved ones from pollution-related respiratory illnesses:
Hand hygiene: Washing your hands frequently reduces the likelihood of infections.
Wear masks: During high-pollution days, N95 masks can filter out harmful particles and protect your lungs.
Monitor AQI: Stay indoors on days when the air quality index (AQI) is high.
Avoid smoking: Smoking further damages the lungs and weakens the respiratory system.
Flu vaccinations: Annual flu shots can prevent flu-related complications and reduce the risk of respiratory infections.
Healthy lifestyle: Eating a balanced diet rich in antioxidants and staying hydrated helps strengthen the immune system.
Takeaway
Gurgaon’s pollution levels are a growing concern for public health, contributing to the rise in atypical pneumonia cases, including walking pneumonia. By staying informed and adopting preventive measures, individuals can help protect themselves from the harmful effects of polluted air.
If you or someone you know is experiencing ongoing respiratory symptoms, it is important to consult an internal medicine doctor near you to receive a proper diagnosis and treatment plan. Early intervention and proactive care are key to managing pollution-related pneumonia effectively.
