As the monsoon rains receive rainfall in Delhi-NCR and other parts of India, viral fever is often more aggressive and difficult to return to predict before before. Doctors say that a dangerous mixture of climate change, urban lifestyle, and weak immunity is fueling this change, which struggles to maintain public health systems.

Today in a conversation with India, Dr. Sanchian Roy, Senior Advisor, Internal Medicine, Apollo Spectra Hospital, Chirag Enclave, Delhi, why seasonal diseases like dengue and influenza no longer follow the patterns that people were familiar with once.

Climate, lifestyle and virus converted

“In recent years, cases of dengue, influenza, viral fever have increased continuously due to a mixture of urbanization, population mobility and environmental changes,” Dr. Roy said. In crowded cities, poor waste management, irregular rainfall, and ups and downs are making ideal breeding basis for viruses so that they can grow well beyond their traditional cycles.

According to him, the problem is no longer limited to the monsoon months. He said, “The convergence of climate, lifestyle and viral development plays a major role in changing these patterns, which makes the outbreak less estimated and more intense than a decade ago,” he explained.

Monsoon no longer means seasonal fever alone

India’s changed weather patterns are giving long-term lifelines to vector-renovated and respiratory infections. “Warm temperatures and converted monsoon patterns extend the mosquito reproductive seasons, especially for dengue and chikungunia. Heavy rain produces stable water pockets that are ideal for mosquito larvae. Increase in humidity increases viral existence, while unseasonal rain traditional infection is blurred at time.”

He warned that influenza is also behaving differently. “Sudden increase in temperature also increases respiratory vulnerability. Climate change has disrupted seasonal forecast, viral infection occurs outside their specific peaks.”

Public health experts resonate this anxiety, calls for weather -related disease forecasting models. The traditional calendars of “fever season” may no longer be enough.

New strains or low immune post-coveds?

Another big question is whether the viruses themselves are getting stronger – or whether humans have become more weak after epidemic. Dr. Roy believes that it is both.

He said, “New strains of viruses such as dengue and influenza are developing to bypass the leading immunity for more severe and etipical presentations,” he said. At the same time, he said, “From exposure to regular infections during lockdown, subsequent covids have left more susceptible, combined with immune fatigue.”

This “dual phenomenon viral development and host vulnerability makes normal fever more aggressive,” he explained, prolonged illness and high hospitalization rate.

Antibiotic abuse deteriorates crisis

One of the silent but important contributors in the complications, Dr. Roy insisted, self-medication. “Antibiotics have no role in the treatment of viral fever, yet their misuse remains widely. Excessive use not only fails to treat infection, but also obstructs intestine microbyota, reduces immunity.”

Delay in diagnosis and improper treatment, he warned, can lead to serious complications such as dengue shock or influenza pneumonia. Worse, misuse of fuel becomes difficult to manage antimicrobial resistance, bacterial co-transfusions.

Viral trends

To deal with these developed challenges, Dr. Roy emphasized the readiness and personal responsibility of a dual approach system.

“Public health systems should strengthen monitoring, vector control and vaccination programs, while integrating climate data more effectively to predict outbreaks,” he said. Hospitals, he said, should be prepared seasonally with test capacity and isolation protocols.

On the individual front, preventive measures are important, mosquitoes control breeding, take flu vaccination, wearing masks during the surge, and avoid self-medication.

Dr. Roy concluded, “It is important to connect community awareness with systematic readiness, ensuring that the trends of viral fever do not overwhelm the healthcare system or move forward in seasonal crises,” Dr. Roy concluded.

Public health experts say that India is now in a new phase where old seasonal chakras of fever cannot be trusted. With dengue appearing in unexpected months, influenza is showing unusual patterns, and climate -associated risks only increases, the focus will have to transfer the focus to active prevention from reactive treatment.

For individuals, this means to be cautious not only in monsoon but throughout the year. For policy makers, this means investing in early warning systems, climate -related health forecasts, and better city infrastructure to curb breeding of mosquitoes.

If left uncontrolled, the new era of viral fever can not only bring unexpected outbreaks, but can also continuously make public health emergency conditions.
