Covid-19, swine flu and RSV cases rise in Mumbai as hospitals report surge in respiratory illnesses

Hospitals and private clinics across Mumbai are reporting a sharp increase in respiratory illnesses, with Covid-19, H1N1 (swine flu), influenza A and respiratory syncytial virus (RSV) infections driving a growing number of patients to seek medical care for high fevers and severe upper respiratory symptoms.

Doctors say H1N1 had dominated outpatient departments for nearly a month, but Covid-19 cases have risen suddenly over the past week. According to reports by the Times of India, laboratories at major facilities such as Breach Candy Hospital are identifying more than seven positive cases of Covid-19 or H1N1 each day.

The infections are causing high fevers ranging from 102°F to 103°F, body aches and deep chest congestion, making it difficult to distinguish between the viruses without diagnostic PCR tests, according to reports

Alongside respiratory illnesses, hospitals including Fortis Hospital in Mulund are also recording an increase in cases of viral gastroenteritis, commonly known as stomach flu.

Delayed monsoon linked to surge

According to Brihanmumbai Municipal Corporation Executive Health Officer Dr Daksha Shah and city epidemiologists, changing weather conditions have contributed to the sudden rise in cases.

Reports said the delayed arrival of the monsoon has led to prolonged periods of high humidity and stagnant atmospheric conditions, allowing respiratory viruses to remain suspended in the air for longer than usual.

Health officials expect the number of cases to decline once steady and heavy rainfall sets in and helps clear the atmosphere.

Vulnerable groups face greater risk

Doctors said the currently active strain of Covid-19 remains mild for most people and rarely requires intensive care on its own. However, senior pulmonologists have warned that elderly people, pregnant women and individuals with underlying conditions such as diabetes or chronic lung diseases are at a higher risk of complications.

They added that overlapping viral infections can significantly weaken the lungs' interstitial tissues and increase the likelihood of secondary infections.

Health experts have cautioned against taking antibiotics or paracetamol without medical advice, warning that self-medication can mask serious conditions or contribute to drug resistance.

Health departments have advised people to wear face masks in crowded public spaces, including local trains and markets, and to maintain proper hand and cough hygiene.

People in high-risk groups have also been advised to regularly monitor oxygen levels and body temperature using a pulse oximeter and seek immediate medical attention if breathing becomes difficult.

Reports said the classic symptoms of Covid-19, H1N1 and RSV overlap considerably, although each infection affects the respiratory system differently.
