The Covid-19 pandemic was slotxo โบนัส preventable, an independent review panel has said.
The panel, set up by the World Health Organization, said the combined response of the WHO and global governments was a "toxic cocktail".
The WHO should have declared a global emergency earlier than it did, its report said, adding that without urgent change the world was vulnerable to another major disease outbreak.
More than 3.3 million people around the world have now died of Covid.
While the US and Europe are beginning to ease restrictions and resume some aspects of pre-pandemic life, the virus is still devastating parts of Asia.
India in particular is seeing record-breaking numbers of new cases and deaths, with severe oxygen shortages in hospitals across the country.
Countries neighbouring India, such as Nepal, are also seeing surges of the virus.
What did the report say?
Covid-19: Make it the Last Pandemic, was compiled by the Independent Panel for Pandemic Preparedness and Response.
Its aim was to find answers as to how the virus had killed more than 3.3 million people and infected more than 159 million.
"The situation we find ourselves in today could have been prevented," co-chair Ellen Johnson Sirleaf, a former president of Liberia, told reporters.
"It is due to a myriad of failures, gaps and delays in preparedness and response."
The panel argued that the WHO's Emergency Committee should have declared the outbreak in China an international emergency a week earlier than it did.
