The head of the World Health Organization said Wednesday that there has been a 90% drop in global COVID-19 deaths since February, which he called a "cause for optimism" but still urged "caution" amid the ongoing pandemic.
"Just over 9,400 COVID-19 deaths were reported to WHO last week -- almost 90% less than in February of this year, when weekly deaths topped 75,000," WHO Director-General Tedros Adhanom Ghebreyesus said during a virtual press briefing from the U.N. agency's Geneva headquarters.
"We have come a long way, and this is definitely cause for optimism, but we continue to call on all governments, communities and individuals to remain vigilant," he added. "Almost 10,000 deaths a week is 10,000 too many, for a disease that can be prevented and treated."

"WHO continues to urge caution, and we continue to urge everyone to be fully vaccinated -- including getting your next dose if it’s due," he said.
A novel coronavirus now known as SARS-CoV-2 was first identified from an outbreak in Wuhan, China, in December 2019. The virus, which causes the disease COVID-19, quickly spread around the globe, prompting the WHO to declare a pandemic in March 2020.

The highly contagious omicron variant and its fast-spreading subvariant BA.5 are currently the dominant versions of the virus globally, according to the WHO.
A number of vaccines against COVID-19 have been developed and approved around the world, including new bivalent booster shots that target omicron subvariants. More than 12.8 billion doses of COVID-19 vaccines have been administered worldwide, according to Johns Hopkins data.
