<p><span style="font-weight: 400;">A cough that continues for weeks despite one or more courses of antibiotics should not be ignored. In India, fungal lung infections are sometimes mistaken for bacterial pneumonia or smear-negative tuberculosis because the early symptoms can look very similar, including cough, fever, tiredness, weight loss, chest discomfort, and breathlessness.</span></p>
<p><span style="font-weight: 400;">This may result in the overuse of antibiotics, sometimes without a clear diagnosis. Antibiotics treat bacteria, not fungi. Taking them unnecessarily will not clear a fungal infection and can contribute to antibiotic resistance, making genuine bacterial infections harder to treat in the future. A persistent cough needs a fresh medical assessment rather than simply another antibiotic prescription.</span></p>
<p><span style="font-weight: 400;">Fungal infections of the lungs are not the most common cause of cough, but they are especially important in people with pre-existing lung disease, diabetes, weakened immunity, or a history of TB. TB can leave cavities or scars in the lungs, where certain fungi may later grow.</span></p>
<h2><strong>Common Fungal Infections Affecting The Lungs</strong></h2>
<h3><strong>Aspergillus / Aspergillosis</strong></h3>
<p><span style="font-weight: 400;">Aspergillus is a common fungus found in the environment. It can cause different forms of lung disease, particularly in people with damaged lungs. Symptoms may include a chronic dry or wet cough, wheezing, fatigue, weight loss and, in some cases, coughing up blood. </span><span style="font-weight: 400;">People with previous TB, asthma, COPD, bronchiectasis or lung cavities are at higher risk. In chronic pulmonary aspergillosis, symptoms may develop slowly over months and can closely resemble TB.</span></p>

<h3><strong>Mucorales / Mucormycosis</strong></h3>
<p><span style="font-weight: 400;">Often called “black fungus”, mucormycosis is a serious infection that needs urgent treatment. Pulmonary mucormycosis may cause worsening cough, severe chest pain, shortness of breath and fever. </span><span style="font-weight: 400;">Some people may also experience facial pain or nasal congestion if the sinuses are involved. The infection is more likely in people with uncontrolled diabetes, severe immunosuppression, blood cancers, organ transplants or heavy and prolonged steroid use.</span></p>

<h3><strong>Candida / Candidiasis</strong></h3>
<p><span style="font-weight: 400;">Candida can cause thrush in the mouth and throat, producing soreness and white patches. It is frequently found in sputum samples from hospitalised patients, but true Candida pneumonia is uncommon and requires careful confirmation.</span></p>
<p><span style="font-weight: 400;">People in intensive care, those on ventilators, and severely immunocompromised patients may be at risk of invasive Candida infection. A cough with sputum, chest tightness, low-grade fever and oral thrush should be assessed in the full clinical context.</span></p>
<h2><strong>How Doctors Tell The Difference</strong></h2>
<p><span style="font-weight: 400;">Symptoms alone cannot confirm a fungal infection. A pulmonologist may request a high-resolution CT scan to look for cavities, fungal balls, nodules, or other changes in the lungs. </span><span style="font-weight: 400;">A sputum fungal culture can help identify an organism, although it may take time and is not always conclusive.</span></p>
<p><span style="font-weight: 400;">Further tests may include bronchoscopy, where fluid or tissue is collected from the airways. Blood tests such as Galactomannan may be used to look for evidence of Aspergillus, while Beta-D-Glucan is a marker that may support suspicion of several fungal infections. For chronic aspergillosis, Aspergillus-specific antibody tests can also be useful.</span></p>
<p><span style="font-weight: 400;">Treatment depends entirely on the fungus involved, the severity of the illness, and the person’s overall health. Antifungal medicines are different from antibiotics and should only be started under medical supervision. </span><span style="font-weight: 400;">If you have a cough that is not improving, especially if it is accompanied by blood in the sputum, weight loss, breathlessness, or a past history of TB, consult a pulmonologist promptly.</span></p>
