A recent medical study conducted across several hospitals in North India has identified a significant rise in chest infections caused by lesser-known bacteria, diverging from the usual culprits such as Streptococcus pneumoniae and Haemophilus influenzae.
Researchers say these infections are emerging due to antibiotic misuse, pollution exposure, and weakened immunity following recent viral outbreaks.
Key Findings From The Study
The research, conducted by a consortium of microbiologists and pulmonologists, identified rare bacterial strains including Moraxella catarrhalis, Acinetobacter baumannii, and Nocardia species as rising causes of lower respiratory infections.
Hospitals in Delhi, Chandigarh, Punjab, and Haryana reported a 20–25% increase in such infections in the last year.
The infections were found to be more resistant to first-line antibiotics, often requiring advanced or combination therapies.
Who Is Most At Risk?
The study found that the most affected groups include:
Elderly individuals with chronic illnesses such as COPD or diabetes.
Smokers and industrial workers exposed to pollutants and dust.
Children and immunocompromised patients, whose bodies are less able to fight emerging pathogens.
Doctors warn that symptoms — persistent cough, chest pain, fever, and shortness of breath — can mimic common flu or bronchitis, delaying timely diagnosis.
Antibiotic Resistance and Diagnostic Challenges
Experts attribute the rise to self-medication and incomplete antibiotic courses, which allow resistant strains to thrive.
Many infections go undetected due to limited bacterial culture testing and overlapping symptoms with viral illnesses.
The study urges hospitals to adopt advanced molecular diagnostics and recommends public awareness campaigns to curb misuse of antibiotics.
Environmental & Seasonal Factors
High air pollution levels in North Indian cities — especially during the post-monsoon and winter months — worsen respiratory conditions.
Pollutants weaken lung defenses, creating an ideal environment for bacterial colonization and infection spread.
Expert Insights
Dr. Kavita Mehra, a pulmonary specialist involved in the study, noted:
“These infections are often overlooked or misdiagnosed as simple viral bronchitis. Early testing and rational antibiotic use are essential to prevent complications.”
She emphasized the importance of awareness among primary care physicians and community health workers to detect these bacteria early.
What Can You Do To Protect Yourself
Avoid self-medicating with antibiotics.
Use masks in polluted areas or during smog-heavy days.
Maintain proper ventilation and hygiene at home.
Strengthen immunity through balanced diet and regular exercise.
Consult a doctor if cough or fever lasts more than one week.
❓ FAQs:
1. Which bacteria are causing the rise in infections?
Bacteria like Moraxella catarrhalis, Nocardia, and Acinetobacter are increasingly being found in North India’s respiratory cases.
2. Why are these infections spreading now?
Experts cite antibiotic misuse, pollution, and weakened immunity as major triggers behind the rise.
3. Are these infections contagious?
Some bacterial infections can spread through airborne droplets, though transmission rates are lower compared to viral infections.
4. Can these be treated easily?
Treatment is possible but may require stronger or combination antibiotics, depending on the bacterial strain and resistance pattern.
5. How can people prevent such infections?
Avoid pollution exposure, get regular check-ups, and follow doctor-prescribed antibiotic courses only.
