"We are deeply concerned both by the alarming levels of spread and severity and by the alarming levels of inaction. We have therefore made the assessment that COVID-19 can be characterised as a pandemic," WHO Director General Tedros Adhanom Ghebreyesus told a news conference on Wednesday.

He urged the global community to redouble efforts to contain the outbreak, saying aggressive measures could still play a big role to curb the pandemic.

Now there are more than 118,000 cases in 114 countries and 4,291 people have died, Tedros said, with the numbers expected to climb. The WHO no longer has a category for declaring a pandemic, except for influenza.

Mike Ryan, head of the WHO's emergencies programme, said the situation in Iran was "very serious" and the agency would like to see more surveillance and more care for the sick.
The coronavirus, which emerged in China in December, has spread around the world, halting industry, bringing flights to a standstill, closing schools and forcing the postponement of sporting events and concerts.
The WHO declared a public health emergency of international concern, its "highest level of alarm," on Jan.30 when there were fewer than 100 cases of COVID-19 outside China and eight cases of human-to-human transmission of the disease.

WHO officials have signalled for weeks that they may use the word "pandemic" as an descriptive term but stressed that it does not carry legal significance. The novel coronavirus is not the flu.
Under its previous system, the Geneva-based agency declared the 2009 H1N1 swine flu outbreak a pandemic. It turned out to be mild, leading to some criticism after pharmaceutical companies rushed development of vaccines and drugs.

Ryan said the experience with influenza led many people to the false conclusion that a pandemic is uncontrollable once it starts.

The experience of South Korea, Singapore, and China in combating the new virus showed this was not true, he said.

"We have observation that tells us that there is a strong element of controllability in this disease," he told the news conference.

"That doesn't mean we will completely stop it but what it does mean is there is a real chance to blunt the curve, there is a real chance to bend the curve and reduce the number of cases that our health system has to cope with and give the health system a chance to save more lives," he said.
