Feb. 24 (UPI) — Deaths from the coronavirus passed 2,600 in China, and the number of cases surpassed 77,000, on Monday as countries worldwide rushed to contain the spread of the disease within their own borders.

World Health Organization officials on Monday said they are not yet prepared to declare the COVID-19 outbreak a global pandemic, despite the continued rapid growth of the outbreak and new cases in Iran, Italy and South Korea.

Outside of China, there have been 2,074 confirmed cases in 28 countries, including 23 deaths — counting the three new outbreaks.

WHO Director-General Tedros Adhanom Ghebreyesus called the new outbreaks “deeply concerning,” but said that “for the moment, we are not witnessing the uncontained global spread of this virus.”

The decision is based on the agency’s ongoing assessment of the diseases spread threat, and could change as facts on the ground change, officials said. With COVID-19 causing epidemics in different parts of the world, Ghebreyesus said individual countries require calm, tailored responses and declaring a pandemic too early could increase fear and hold back efforts to slow spread of the virus.

The WHO does not use a numerical threshold for determining a pandemic, rather eschewing to judgement based on the definition that “an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people.”

Mike Ryan, head of the WHO’s emergency response program, said the fact that Chinese officials appear to have largely limited the outbreak to one region of the country and that numbers appear to be slowing or declining suggests COVID-19 is containable.

At the same time, he said, the continued spread to other countries, as well as lack of clarity on whether the coronavirus will remain endemic in humans or morph into a “seasonal” disease has officials exercising caution about any declaration.

COVID-19 in China

Chinese health officials have reported 150 new deaths from the deadly coronavirus over the previous 24 hours, increasing the death toll for mainland China to 2,618 since the epidemic began in December.

China’s National Health Commission announced the new death toll in its daily update Monday morning, stating 149 of the newly reported deaths occurred in Hubei province, the epicenter of the outbreak.

The health officials also said there were 460 new confirmed cases over Sunday, increasing the total of confirmed cases to 77,362.

The announcement of the new figures came as officials in Hubei’s capital of Wuhan reversed an earlier decision to relax some of the tight restrictions placed last month upon the city of 11 million at the center of the outbreak. Hubei is where 2,495 people have died from the disease with 1,987 in Wuhan, the province said in a statement on Monday.

In a statement Monday afternoon, Wuhan government officials said the easing of lockdown restrictions was declared “invalid” as it was issued without consent from “the main leaders.”

“We have seriously criticized the relevant personnel,” the statement read.

The city was placed under a strict lockdown on Jan. 23 to clamp down on the virus’ spread, and the city announced in a statement early Monday that non-residents who do not exhibit symptoms may finally leave Wuhan.

In the new statement issued hours later, the officials called on Wuhan to “resolutely implement” Chinese President Xi Jinping’s orders to prevent the outbreak’s spread.

The WHO said Monday that its joint mission to China has concluded, with its final report suggesting that the epidemic in China peaked and plateaued between January 23 and February 2, and has been in decline ever since.

The fatality rate linked to COVID-19 is estimated at 2 percent to 4 percent in Wuhan, and about 0.7 percent outside the city. Those with mild disease have recovered within two weeks, and people with more severe disease may need three to six weeks to completely recover.

“The measures taken in China averted a significant number of cases,” Ghebreyesus said, adding that China’s situation suggests the virus can be contained in many countries.

Growing worldwide outbreaks

Meanwhile, as the rate of infection appears to slow in China, other countries are scrambling to contain the disease.

South Korea also announced more cases Monday, and Seoul’s Centers for Disease Control and Prevention reported two new deaths raising the death toll to seven.

Asian Airlines said it would suspend its Daegu-Jeju route from Tuesday and Air Busan said it canceled its Daegu to Jeju and Daegu to Taipei flights last week when concerns emerged.

The increase in infections also caused Australia to update its travel advisory for the Asian nation warning its citizens to “exercise a high degree of caution” visiting South Korea and to not visit Daegu.

Australia also warned residents to exercise a high degree of caution in Japan based on the advice of its medical officials due to “a heightened risk of sustained local transmission” of COVID-19.

In Europe, Italy has reported the largest outbreak outside Asia with 157, according to a tally kept by the Johns Hopkins Center for Systems Science and Engineering.

The outbreak has forced the nation to suspend its famed Venice Carnival, ban public and private meetings through Saturday and cancel sporting events.

In the Middle East, Kuwait and Bahrain announced their first confirmed cases of the disease.

The Bahrain Ministry of Health said the infected Bahraini citizen arrived from Iran and was suspected of having contracted the virus as he exhibited symptoms, according to a statement carried by the Bahrain News Agency.

The patient was transferred to the Ebrahim Khalil Kanoo Medical Center where he was confirmed infected with COVID-19 and is currently receiving treatment in isolation, it said.

The government said it will be upping its measures to prevent contamination of the virus, including monitoring those who arrive from infected countries.

In Kuwait, health officials confirmed three people have been infected with the disease, the Kuwait News Agency reported.

Globally, the death toll from the virus reached at least 2,619 with more than 79,350 people infected, according to the tally by Johns Hopkins.
