This statement appears to refer to the theory that the COVID-19 virus might have originated from a lab leak in Wuhan, China. This theory has been a topic of controversy and has been the subject of ongoing investigations. The statement you shared seems to suggest that the US has provided intelligence to the UK saying the likelihood of such a lab leak is high, as per a report. But please note that these details are frequently changing due to ongoing research. For the most accurate and up-to-date information, I recommend checking reliable news sources or official health organization statements.
