Why are dengue cases on the rise in India, even during non-peak seasons?

INDIA RISE SINCE 2020

Since 2020, dengue cases have increased rapidly in India. More than 32, 000 cases were reported in the first quarter of 2024, which is nearly twice as many as they were during the same time next year.

The country recorded about 290, 000 cases last month – 50, 000 more than the year before.

The subcontinent’s ongoing rain season, which usually lasts from June to September, has contributed to the increase in infections. In nations like Nepal, Bangladesh, and Sri Lanka, instances have been reported in much higher amounts throughout the year.

According to authorities, global warming is to blame for the longer rainfall time and higher humidity levels.

The Aedes mosquitoes thrives in ideal conditions thanks to the subtropical climate and common waterlogging during the rain season.

Some also cited South Asia’s fast, unregulated urbanization.

Hundreds live in densely populated communities without appropriate water supply, sanitation, or waste management techniques. Mosquitoes can easily reproduce in sluggish water that frequently collects in the streets.

Adarsha Kapoor, an industrial planner, suggested ensuring a constant supply of piped water so that no one needed to keep water in bottles and jars. Places that are prone to waterlogging could also be improved through repair, he added.

However, Ms. Bimla claimed that these methods do not address her and her neighbors ‘ issues right away.

They want authorities to make sure that all years, not just when circumstances rise, are treated for dengue and the drains are covered.
