Private hospitals across Chennai are recording a sharp rise in patients presenting with respiratory infections, influenza, and dengue, straining outpatient departments and inpatient wards as the city heads into the monsoon season. Emergency department wait times for beds have stretched to as long as 12 hours at several facilities, with patients being shifted from Intensive Care Units to general wards also facing significant delays.

What Patients Are Experiencing

The most commonly reported symptoms include high fever, sore throat, cold, persistent cough, severe body and leg pain, chest discomfort, fatigue, and loss of appetite. Among children and adolescents, doctors are observing prolonged fever and extreme exhaustion; a small number have also developed confusion or delirium triggered by high fever.

Some patients require nebulisation or intravenous fluids, which has contributed directly to the spike in hospital admissions. Doctors say early medical attention is particularly critical for those presenting with breathing difficulties, persistent high fever, or signs of dehydration.

What Doctors Are Saying

Dr R. Rajammal, an infectious diseases expert at a private hospital in Chennai, described conditions at emergency departments as severely stretched. 'When patients come into the emergency room, the wait for a room or bed extends up to 12 hours. Similarly, patients who need to be shifted out of the ICU have long waits for rooms or beds in general wards. The waiting time in outpatient units has also increased considerably,' she said.

Doctors across multiple city hospitals have confirmed similar trends. While most infections are mild and resolve with medication, rest, and hydration, they caution that elderly patients and those with co-morbidities remain at heightened risk of complications. Fatalities, though uncommon, can occur in vulnerable groups.

Viruses Behind the Surge

Respiratory illnesses driven by viruses including respiratory syncytial virus (RSV), adenovirus, rhinovirus, and parainfluenza account for a large share of the current caseload. Influenza, including the H1N1 strain, and dengue are also being diagnosed frequently. Doctors have advised residents against ignoring fever or resorting to self-medication, especially when symptoms persist beyond a few days.

Monsoon Risk and Precautions

With the monsoon approaching, doctors have warned that stagnant water could accelerate mosquito breeding and amplify dengue transmission across the city. They have called for intensified municipal mosquito-control drives and greater public awareness campaigns to prevent a further escalation in case numbers.

Residents are being urged to maintain hand hygiene, avoid close contact with infected individuals, and wear masks in crowded spaces if they are experiencing respiratory symptoms. This surge follows a seasonal pattern seen in prior pre-monsoon periods in Tamil Nadu, but healthcare workers say the current strain on hospital infrastructure is notably acute.
