Pneumonia is an infection of the lung tissue itself, usually bacterial or viral, causing cough, fever and often breathlessness. It ranges from mild, home-treatable infections to severe illness needing admission — which is why the most important step is judging severity, not simply handing over an antibiotic. A cough with fever that is getting worse rather than better deserves a fever and infection assessment.
Sometimes rust-coloured or with traces of blood.
Breathing may feel fast or laboured.
Often worse on deep breaths or coughing.
The same symptoms can be mild or serious — assessment decides which, and where it is treated.
| Feature | Milder chest infection | Pneumonia needing closer care |
|---|---|---|
| Breathing | Comfortable at rest | Breathless, fast breathing |
| General state | Eating, drinking, alert | Confused, very weak, not eating |
| Tests | Often none needed | Chest X-ray, blood tests, oxygen check |
| Setting | Usually home treatment | May need hospital admission |
Severity also depends on age and conditions like diabetes, heart or lung disease, which lower the threshold for tests and admission.
Assessment starts with examining the chest and checking breathing and oxygen levels. A chest X-ray confirms pneumonia and shows its extent; blood tests help judge severity and cause. Not every cough needs an X-ray — the examination guides whether one is warranted.
Most community-acquired pneumonia is treated with antibiotics chosen to fit the likely cause and your circumstances, alongside fluids, fever control and rest. Many people recover at home with review; others need admission for oxygen or intravenous treatment. Specific medicines and doses are decided in consultation after assessment.
Admission is considered for breathlessness or low oxygen, confusion, low blood pressure, an inability to eat or drink, or failure to improve on treatment — and more readily in the elderly or those with diabetes, heart, lung, kidney or immune conditions. Recognising this early is central to safe management.
A consultant physician in Greater Noida judges how severe a chest infection is, whether an X-ray and tests are needed, and whether it is safe to treat at home — the decisions that matter most in pneumonia. It is managed within a broader fever and infection assessment; complex or recurrent infections are also seen as an infectious disease physician.
A cough with fever is not treated blindly. The aim is to assess severity and oxygen, decide rationally whether an X-ray and antibiotics are needed, and make a clear home-versus-hospital decision.
Not smoking, managing conditions like diabetes well, and vaccination (including flu and pneumococcal vaccines where appropriate) lower the risk and severity of pneumonia — see adult vaccination.
"Dr. Manuj Sondhi is indeed an infectious diseases expert. My 70-year-old father, a spinal TB patient, could not tolerate his first-line treatment. Dr. Sondhi assessed his case personally and modified the treatment to a level my father could tolerate."
"He is knowledgeable and patient, and takes the time to listen carefully. The most important thing is that he doesn't prescribe extra medication unless absolutely necessary — he focuses on diet and lifestyle changes. Highly recommend."
