DIRECTOR-General of the World Health Organisation (WHO), Dr Tedros Adhanom Ghebreyesus, confirmed on Wednesday that the organisation has characterised coronavirus as a pandemic.

He said: "Pandemic is not a word to use lightly or carelessly. It is a word that, if misused, can cause unreasonable fear, or unjustified acceptance that the fight is over, leading to unnecessary suffering and death.

"Describing the situation as a pandemic does not change WHO's assessment of the threat posed by this coronavirus. It doesn't change what WHO is doing, and it doesn't change what countries should do."

He added: "We have never before seen a pandemic sparked by a coronavirus. And we have never before seen a pandemic that can be controlled at the same time. WHO has been in full response mode since we were notified of the first cases.

"We have called every day for countries to take urgent and aggressive action. We have rung the alarm bell loud and clear."

He has appealed to affected countries to "detect, test, treat, isolate, trace and mobilise" to prevent the Covid-19 outbreak worsening.

"We cannot say this loudly enough or clearly enough or often enough: all countries can still change the course of this pandemic," he told a briefing in Geneva.

"If countries detect, test, treat, isolate, trace, and mobilise their people in their response, those with a handful of cases can prevent those cases becoming clusters and those clusters becoming community transmission."

"Every sector and every individual" must be involved in the fight against coronavirus, according to the director-general of the World Health Organisation.

He told a briefing: "This is not just a public health crisis. It's a crisis that will touch every sector, so every sector and every individual must be involved in the fight.

"I have said from the beginning that countries must take all of government – all of society – approach, built around a comprehensive strategy to prevent infections, save lives and minimise impact."

He summarised the key areas in tackling the outbreak as "prepare and be ready", "detect, protect and treat", "reduce transmission" and "innovate and learn".

He added: "This is everybody's business. Find, isolate, test, and treat every case and trace every contact."
