Kolkata Hospitals Grapple With Unexpected Pneumonia Influx as Seasons Shift
Despite the gradual departure of winter and rising temperatures, numerous hospitals across Kolkata continue to experience significant congestion due to a steady influx of pneumonia patients. Medical professionals indicate that while temperature fluctuations triggered this increase, the substantial volume of cases arriving at this time of year was entirely unforeseen.
Unusual Winter Patterns and Current Hospital Strain
Throughout the winter months, the number of pneumonia patients in city hospitals showed minimal decline, a pattern that doctors describe as highly unusual. Presently, all three primary forms of pneumonia—streptococcus, klebsiella, and moraxella—are circulating widely, with over half of the admitted patients requiring intensive care unit (ICU) treatment.
At Manipal Hospitals, there has been a notable 10% to 15% surge in pneumonia cases over the past week. Debraj Jash, an interventional pulmonologist at the facility, explained, "The fluctuation in mercury levels directly contributed to this rise in numbers. This spike arrived somewhat earlier than anticipated, and the severity of the disease is more pronounced than usual."
Microbiological Factors and Hospital Occupancy Pressures
Bhaskar Narayan Chaudhury, chief microbiologist at Peerless Hospital, detailed the complex array of pathogens involved. "Allergic conditions are currently prevalent, rendering patients—particularly those at the extremes of age and individuals with comorbidities such as structural lung diseases—more susceptible to viral infections caused by streptococcus pneumoniae, haemophilus influenzae, moraxella catarrhalis, and klebsiella pneumonia. Additionally, we are observing cases involving parainfluenza virus, seasonal coronaviruses, influenza, adenovirus, human rhinovirus, and human metapneumovirus."
This diverse microbial assault has driven hospital occupancy rates above 80%, according to Peerless Hospital CEO Sudipta Mitra.
ICU Capacity Challenges and Patient Outcomes
CMRI Hospital's respiratory ICU has been operating at full capacity since January, forcing several patients to be accommodated in general wards due to consistent ICU unavailability. Raja Dhar, director of pulmonology at CMRI Hospital, noted, "Patients with a history of chronic obstructive pulmonary disease (COPD) who contract pneumonia experience a more severe disease progression compared to those without prior lung conditions. There have been several fatalities, with the mortality rate for pneumonia patients at our hospital estimated between 5% and 10%."
Shifting Patient Profiles and Future Projections
Charnock Hospital reported a slight decrease in pneumonia patients from approximately 20, a figure that had remained stable over the preceding two months. Soumya Sengupta, head of pulmonology at Charnock, stated, "While we continue to admit streptococcus pneumonia patients, there has been a marginal reduction. Currently, viral influenza patients exhibiting similar and extremely severe symptoms have become predominant." Sengupta further warned, "With ongoing temperature fluctuations, we anticipate another potential surge in pneumonia cases."
Ruby General Hospital currently has 22 patients with lung ailments, including severe pneumonia, under critical care, with an additional 12 admitted in wards. Subhashish Datta, general manager of operations at Ruby, remarked, "Pneumonia patient numbers peaked between mid-December and mid-January. Although there was a slight decline, cases have begun to climb again during a period when we typically observe a reduction in lung infections."
Datta added that several patients with COPD and asthma, alongside those diagnosed with pneumonia, have developed further complications such as lung tumors, structural diseases, or more severe forms of pneumonia.
