Over eight per cent of outbreaks reported under India's infectious disease surveillance system between 2018 and 2023 were zoonotic -- spread from animals to humans, such as the COVID-19 pandemic, according to an analysis.

Zoonotic outbreaks consistently peaked during June, July, and August, researchers from the Indian Council of Medical Research-National Institute of Epidemiology, Chennai said.

Typically, about seven zoonotic outbreaks -- also sometimes called 'spillover events' -- occurred in a month, and such instances significantly increased over the years, specifically, post-pandemic, the study published in The Lancet Regional Health Southeast Asia journal found.
