Circulation of SARS-CoV-2 coronavirus among humans and animals threatens the emergence of new dangerous viruses. This is stated in the report of the World Health Organization (WHO).

“The global public health risk associated with COVID-19 remains high,” the report said. The WHO noted that collective immunity to SARS-CoV-2 has now grown significantly. However, its circulation continues at a significant level. According to the organization, this is evidenced by “the percentage of positive test results and wastewater sampling.” The SARS-CoV-2 pandemic began with an outbreak in Wuhan, China, in December 2019. On January 30, 2020, the World Health Organization declared the outbreak a public health emergency of international concern and declared it a pandemic on March 11. As of January 2025, more than 777 million cases have been reported worldwide.
