The World Health Organization (WHO) this week reflected on COVID-19, and ongoing efforts to understand the disease, five years after its emergence.
WHO recalled that on 31 December 2019, its Country Office in China picked up a media statement by the Wuhan Municipal Health Commission from their website on cases of "viral pneumonia" in the city.
"In the weeks, months and years that unfolded after that, COVID-19 came to shape our lives and our world," the UN agency said on Monday.
Worldwide, there have been 777,074,803 confirmed cases of the disease, and more than seven million deaths, according to latest figures.
"We continue to call on China to share data and access so we can understand the origins of COVID-19," WHO said.
"This is a moral and scientific imperative. Without transparency, sharing, and cooperation among countries, the world cannot adequately prevent and prepare for future epidemics and pandemics. "
In marking the five-year milestone, WHO also honoured lives lost to the disease, and recognized those are still suffering from it or from long COVID.
The agency also expressed gratitude to the health workers "who sacrificed so much to care for us, and commit to learning from COVID-19 to build a healthier tomorrow."
