Lung infections can range from mild coughs to life-threatening illnesses. Knowing the different types of lung infections helps in early recognition and timely treatment, especially for vulnerable individuals such as the elderly or those with compromised immunity.
In this blog, we cover the most common types of lung infections in adults, including bacterial, viral, and fungal infections. Besides, pneumonia, bronchitis, TB, COVID and influenza are the most common. We also explore the symptoms, causes, and risk factors for each lung infection type to help you stay informed.
A study from Dr Batra’s Clinic, published in Homeopathic 360, reported a severe pneumonia case with pleural effusion treated successfully with a single dose of Bryonia alba, avoiding surgery. This highlights homeopathy’s potential in managing complex respiratory conditions naturally and non-invasively.
Did You Know? Tuberculosis (TB) is one of the most severe and contagious lung infections, with India accounting for over 27% of the global TB burden, according to the World Health Organisation (2023). Early detection and continuous treatment are key to controlling its spread
What Are Lung Infections?
Lung infections occur when viruses, bacteria, or fungi invade the lungs, leading to inflammation of the airways or lung tissue. In India, respiratory infections are one of the leading causes of illness and hospitalisation, particularly during monsoon and winter seasons.
According to the Indian Journal of Medical Research, lower respiratory tract infections account for 2.7 million deaths globally each year.
Types of Bacterial Lung Infections
Bacterial lung infections often develop quickly and require medical treatment. These are some of the most common and serious types:
- Pneumonia Caused by Streptococcus pneumoniae and other bacteria; symptoms include chest pain, fever, and difficulty breathing
- Tuberculosis (TB) Caused by Mycobacterium tuberculosis; symptoms include persistent cough, night sweats, and weight loss
- Bronchitis Acute bacterial bronchitis is usually short-term but may require antibiotics
These types of bacterial lung infections are more common in people with weakened immune systems, chronic diseases, or smokers
Types of Viral Lung Infections
Viral infections are contagious and often spread through cough, sneezing, or close contact. Common lung infections types caused by viruses include:
- Influenza (Flu)Fever, chills, body ache, and dry cough
- COVID-19Caused by SARS-CoV-2; may range from mild symptoms to severe lung damage
- Respiratory Syncytial Virus (RSV)Affects infants and older adults; causes cold-like symptoms or pneumonia
Dr Batra’s® pro tip:
It is advised to consult a medical professional in cases of lung infection and homeopathy offers a safer solution to not only treat the lung infection but also build immunity to treat lung infection naturally
Types of Fungal Lung Infections
Fungal infections are less common but can be severe, especially in people with low immunity.
- AspergillosisCaused by the fungus Aspergillus; can affect people with asthma or TB
- Histoplasmosis Found in soil; common in farmers and construction workers
- CandidiasisThough rare in lungs, Candida can cause infections in immunocompromised patients
