A new coronavirus that has a greater ability to spread to humans than the one behind the COVID-19 pandemic has been discovered.
HKU5-CoV-2 was found by a Chinese research team led by virologist Shi Zhengli, known as "Batwoman" for her work on coronaviruses, especially at the Wuhan Institute, which has been at the centre of the theory suggesting COVID-19 came from a lab leakâsomething Shi has denied.
The new virus is reportedly related to MERS, a deadlier coronavirus that kills up to a third of people it infects. The news has put health officials worldwide on alert after Covid-19, which emerged in 2019, brought the world to a standstill, claimed millions of lives and upended global stock markets.
Tests showed HKU5-CoV-2 infiltrated human cells in the same way as SARS-CoV-2, the virus behind Covid. The Beijing-funded researchers shared their discovery in the journal Cell, stating that it posed a 'high risk of spillover to humans, either through direct transmission or facilitated by intermediate hosts.'
The COVID-19 pandemic is one of the deadliest outbreaks in the world's history. Caused by SARS-CoV-2, it began in Wuhan, China, in December 2019 and quickly spread to Asia and worldwide by early 2020. The World Health Organization (WHO) declared it a public health emergency in January 2020 and recognized it as a pandemic on March 11.
The new HKU5-CoV-2 is a coronavirus belonging to the merbecovirus family of pathogens. Merbecoviruses have been detected in minks and pangolins - the animal believed to be the intermediary for Covid between bats and humans.
This, the scientists wrote, "suggests frequent cross-species transmission of these viruses between bats and other animal species". They added: 'This study reveals a distinct lineage of HKU5-CoVs in bats that efficiently use human [cells] and underscores their potential zoonotic risk.'
