Study: Animal-to-Human Disease Outbreaks Increase Post-Pandemic
Scientists looked at disease outbreaks from 2018 to 2023 and found that about 8% of them spread from animals to humans.
These types of outbreaks were most common in the months of June, July, and August.
Japanese encephalitis, leptospirosis, and scrub typhus were the most frequent zoonotic diseases.
The northeast and southern regions of the country reported the most outbreaks.
Scientists noticed that there was less delay in reporting outbreaks over the years, but still, a third of the outbreaks were reported late.
The study suggests that more research is needed, especially in the areas with the highest number of outbreaks.
The team also found gaps in the weekly reports.
8.3% of disease outbreaks analyzed from 2018-2023 were zoonotic.
Zoonotic outbreaks peaked in June, July, and August.
Japanese encephalitis accounted for 29.5% of zoonotic outbreaks.
Northeast India reported 35.8% of zoonotic outbreaks.
Reporting delays for outbreaks decreased over the years.
