From the Guardian’s live coronavirus page:

Today is exactly one year since China informed the World Health Organization that cases of “pneumonia with an unknown cause” had been reported in Wuhan, the WHO director general has told a press briefing. 

Giving a brief history of the pandemic so far, Tedros Adhanom Ghebreyesus hailed “the extraordinary cooperation between the private and public sector in this pandemic” which led to the fast circulation of diagnostic tests and, later, the development of several vaccine candidates in record time. 

He went on:

There will be setbacks and new challenges in the year ahead. For example, new variants of Covid-19 and helping people who are tired of the pandemic continue to combat it.
