At least two Zika patients have reported co-infection of chikungunya and dengue in Pune, India. The Times of India reported on July 5, 2024, that an official from the National Institute of Virology (NIV) told the media that Pune City is a hotspot for vector-borne diseases.
Therefore, co-infections with chikungunya and dengue are not entirely out of the blue. However, their severity can be debatable, says the NIV.
