Mumbai is witnessing a simultaneous rise in Covid-19, H1N1 (swine flu), Influenza A and Respiratory Syncytial Virus (RSV) infections, with doctors and health officials attributing the surge largely to delayed monsoon conditions and prolonged humidity.
Hospitals and private clinics across the city have reported an increased flow of patients suffering from high fever, body aches, sore throat, cough and respiratory discomfort. According to doctors, while H1N1 cases had dominated outpatient departments over the past month, Covid-19 infections have shown a noticeable uptick during the past week.
Laboratories at major healthcare facilities are reportedly detecting several Covid-19 and H1N1 cases daily. Medical experts say the symptoms of the circulating viruses often overlap, making it difficult to distinguish between them without specialised diagnostic tests such as PCR panels.
Apart from respiratory illnesses, hospitals have also recorded a rise in cases of viral gastroenteritis, commonly known as stomach flu.
Delayed monsoon under scanner
Health experts believe the delayed arrival of the monsoon has contributed significantly to the spike. According to civic health officials, persistent humidity and stagnant atmospheric conditions have enabled respiratory viruses to remain airborne for longer periods. They expect infection rates to decline once sustained rainfall improves air circulation and environmental conditions.
Doctors have stressed that the current Covid-19 strain appears mild for most people. However, elderly individuals, pregnant women and those with underlying conditions such as diabetes or chronic respiratory diseases remain vulnerable to complications. Specialists warn that simultaneous or successive viral infections can weaken the lungs and increase the risk of secondary infections.

Doctors urge caution
Medical professionals have advised against self-medication, particularly the indiscriminate use of antibiotics or fever-reducing drugs without medical supervision. Such practices can mask symptoms or contribute to antibiotic resistance.
Health authorities have urged residents to wear masks in crowded places, maintain hand hygiene and follow proper cough etiquette. High-risk individuals have been advised to monitor oxygen saturation levels and body temperature regularly and seek prompt medical attention if symptoms worsen.
Symptoms and warning signs
Experts noted that Covid-19 commonly causes severe fatigue, fever and body aches, while H1N1 is associated with a sudden onset of high fever, chest congestion and headaches. RSV, meanwhile, often produces heavy nasal discharge, wheezing and a phlegm-producing cough.
Doctors have identified breathing difficulties, persistent chest pain, confusion, bluish lips and inability to retain fluids as warning signs requiring immediate hospitalisation.
