In September 2021, many people in Western Uttar Pradesh were struck by “mystery” fevers. Some even succumbed to them. Later the Central team found out that the fevers were mostly dengue fevers, or caused by scrub typhus and leptospirosis.
The fevers are “mysterious” often because local governments are not able to detect the cause soon enough. This is also because some of these areas have never seen these kinds of diseases. Climate change, urbanisation and a change in ways of living are some of the reasons for such diseases surfacing.
In this episode of Science And Us, Suno India’s Menaka Rao speaks to Ramesh Dhiman, a senior scientist who retired from the National Institute of Malaria Research. Dhiman has been tracking the effects of climate change on vector-borne diseases such as malaria, dengue, kala-azar among others for decades now.
