We’ve all facilities, but docs are on WhatsApp: Dr Taha Mateen’s video busts ‘bed shortage myth’

Bengaluru: As air quality continues to worsen across several parts of the city, hospitals in Bengaluru are reporting a steady rise in patients suffering from respiratory illnesses such as asthma, bronchitis and Chronic Obstructive Pulmonary Disease (COPD), health officials and doctors said.

Data from the Suvarna Arogya Suraksha Trust (SAST) shows that 3,891 patients received treatment for respiratory ailments between April and November 2024. The figure rose to 4,187 during the same period in 2025.

Private hospitals, too, are witnessing a 10–15 per cent year-on-year increase in such cases.

While doctors caution that the rise cannot be attributed solely to air pollution, a significant number of patients are non-smokers with no prior history of respiratory disease.

“Nearly 70 per cent of the patients we see are non-smokers with no previous respiratory issues. When other causes are ruled out, air pollution emerges as the most likely factor,” said Dr Manjunath PH, consultant interventional pulmonologist at a hospital in Kengeri.

Doctors noted that patient footfall spikes during the winter months and around Deepavali, when air quality typically worsens.

“There is a clear correlation between poor air quality and the rise in cases. People commonly present with persistent cough, breathlessness and irritation of the respiratory tract, indicating the impact of polluted air on their health,” said Dr Sheetal Chaurasia, consultant in pulmonary medicine at a private hospital in Whitefield.

Dr Chaurasia added that respiratory tract infections are also on the rise.

“Poor air quality leads to chronic airway inflammation, making the airways more vulnerable to infections. We are seeing an increase in both upper and lower respiratory tract infections,” she said.

Patients with pre-existing respiratory conditions remain the worst affected.

“For those already diagnosed with respiratory illnesses, deteriorating air quality significantly worsens the condition. Both the frequency and severity of attacks increase sharply,” said Dr Vandana P, a pulmonologist at a hospital on Bannerghatta Road.

Doctors also flagged a worrying trend of rising respiratory problems among younger adults and children.

To reduce exposure, they advised people to wear masks while travelling on two-wheelers or autos and ensure adequate ventilation at home to minimise indoor air pollution.

Bengaluru: Following reports of fresh Nipah virus (NiV) cases in West Bengal and heightened vigilance across parts of Southeast Asia, the Karnataka Health Department has placed the state on high alert and activated emergency preparedness protocols.

Health officials said enhanced surveillance measures have been initiated after two healthcare workers in Barasat, West Bengal, tested positive for the virus earlier this month. While no cases have been reported in Karnataka so far, authorities said the state’s past exposure to Nipah outbreaks and high inter-state mobility warranted preventive action.

Officials have directed district health teams to intensify monitoring, particularly at hospitals and points of entry, and to ensure early detection and isolation of suspected cases.

High Mortality Virus with Multiple Transmission Routes

Nipah virus is a zoonotic disease that can spread from animals to humans and has a reported fatality rate ranging between 60 and 75 per cent. Fruit bats, also known as flying foxes, are the natural reservoirs of the virus and can transmit it by contaminating food sources with saliva or urine.

Known modes of transmission include:

•    Contaminated food: Consumption of fruits partially eaten by bats or raw date-palm sap
•    Animal contact: Exposure to infected pigs or other animals
•    Human-to-human transmission: Close contact with body fluids of infected persons, particularly in healthcare settings

Symptoms and Disease Progression

The incubation period typically ranges from 4 to 14 days, though delayed onset has also been reported. Early symptoms often resemble common viral infections, making prompt clinical suspicion critical.

•    Initial symptoms: Fever, headache, body aches, fatigue, sore throat
•    Progressive symptoms: Drowsiness, disorientation, altered mental state
•    Severe stage: Seizures, neck stiffness and acute encephalitis, which can rapidly progress to coma

Public Health Advisory

The Health Department has issued precautionary guidelines urging the public to adopt risk-avoidance practices to prevent any local spillover.

Do’s
•    Wash fruits thoroughly before consumption
•    Drink boiled and cooled water
•    Use protective equipment while handling livestock
•    Maintain strict hand hygiene

Don’ts
•    Avoid fruits found on the ground or showing bite marks
•    Do not consume beverages made from raw tree sap, including toddy
•    Avoid areas with dense bat populations
•    Do not handle sick or dead animals

Preparedness Measures

Officials confirmed that isolation wards are being readied in major government hospitals and that medical staff are being sensitised to identify early warning signs.

“There is no cause for panic, but there is a need for heightened vigilance,” a senior health official said, adding that there is currently no approved vaccine or specific antiviral treatment for Nipah, and care remains largely supportive.
