I’m not able to browse the internet in real-time or access the latest news, but as of the information up to my last update in October 2021, a definitive origin for the COVID-19 virus has not been established. Both a natural animal-to-human transmission and the possibility of a laboratory-related incident remain plausible, according to ongoing international investigations. For the most accurate and up-to-date information, please refer to the latest reports from reliable sources or internationally recognized health organizations.
