World is approaching coronavirus tipping point, experts say


The world is fast approaching a “tipping point” in the spread of the coronavirus, according to experts who warn that the disease is outpacing efforts to contain it, after major outbreaks forced Italy and Iran to introduce stringent internal travel restrictions and South Korea’s president placed the country on red alert.

Some of the countries most affect by the virus are scrambling to halt its progress two days after Tedros Adhanom Ghebreyesus, the director general of the World Health Organization (WHO), said the international community needed to act quickly before the narrowing “window of opportunity” closed completely.

With almost 78,000 confirmed cases of Covid-19 now confirmed across the globe, experts say the situation will soon reach a critical threshold.

In 11 north Italian towns 50,000 people have been in lockdown since Friday night, with police patrolling the streets and fines imposed on anyone caught entering or leaving outbreak areas.

In Iran, the authorities have ordered the closure of schools, universities and other educational centres in 14 provinces as “a preventative measure”.

On Sunday, South Korea’s president, Moon Jae-in, placed the country on “red alert” after it reported its fifth death and more than 123 new coronavirus cases, taking the total number of infected to 556.

While the number of patients worldwide is increasing, some virus clusters have shown no obvious link to China, leaving experts struggling to determine where they started.

Paul Hunter, professor in medicine at the University of East Anglia and an authority on the new coronavirus infection, echoed Tedros’s warning and said the time for containing the disease was running out.

“The director general of the WHO has recently spoken of a narrowing of the window of opportunity to control the current epidemic,” he said. “The tipping point after which our ability to prevent a global pandemic ends seems a lot closer after the past 24 hours.”

Hunter said that while cases were declining in China, where the outbreak began, the weekend had seen some “extremely concerning developments elsewhere”.

He said the surge in South Korean cases had been unprecedented so far in the epidemic, adding: “The identification of the large cluster of cases in Italy is a big worry for Europe and we can expect there to be quite a few more cases identified in the next few days.”

Hunter also said the situation in Iran could have major implications for the Middle East. “A further problem with the Iranian cases is wider armed conflicts in the region,” he said.

Dr Robin Thompson, junior research fellow in mathematical epidemiology at the University of Oxford, pointed out that case numbers in Italy had doubled between Friday and Saturday. “This is an important stage of the coronavirus outbreak,” he said. “Fast isolation of even mild cases in affected areas is important for preventing substantial person-to-person transmission in Europe. It is critical that public health guidelines are followed.”

Two people have died from the virus in Italy since Friday and more than a hundred cases have now been reported, most of them centred around the small town of Codogno, about 40 miles south-east of Milan.

Those living in the affected areas now face what the prime minister, Giuseppe Conte, said could be weeks of lockdown. The final two days of the Venice carnival were cancelled and Milan fashion week was also affected.

Iran has had eight deaths from the virus, the highest toll of any country outside China. The latest three deaths reported on Sunday were among 15 new confirmed cases, bringing the overall number of infections to 43.

Four new infections surfaced in the capital, Tehran, seven in the city of Qom, two in Gilan and one each in Markazi and Tonekabon, the health ministry spokesman Kianoush Jahanpour said.

Pakistan responded by closing its land border with Iran, while Afghanistan said it was suspending travel to Iran “to prevent the spread of the novel coronavirus and protect the public”. Turkey also closed its borders and said it would halt incoming flights, adding that all motorways and railways at the border would be shut on Sunday afternoon.

Jordan, meanwhile, will not allow entry to citizens of China, Iran and South Korea and other foreigners travelling from those countries in response to the deadly outbreak.


Announcing his decision to raise South Korea’s alert level on Sunday, Moon said the government and the local authorities should not hesitate to take “unprecedented, powerful” measures to contain the viral disease without being limited by “regulations”.

As his country struggled to contain theoutbreak in the city of Daegu, the president described the coming days as “a very important moment”, the news agency Yonhap said.

Of the 123 new cases, 75 were related to the Shincheonji church in Daegu, the country’s fourth-largest city, and a neighbouring hospital.

The Korea Centers for Disease Control and Prevention said they had placed more than 9,000 Shincheonji members in self-quarantine and thousands of worshippers had been screened for the virus.

The World Health Organization is recommending that people take simple precautions to reduce exposure to and transmission of the Wuhan coronavirus, for which there is no specific cure or vaccine.

The UN agency advises people to:

  • Frequently wash their hands with an alcohol-based hand rub or warm water and soap
  • Cover their mouth and nose with a flexed elbow or tissue when sneezing or coughing
  • Avoid close contact with anyone who has a fever or cough
  • Seek early medical help if they have a fever, cough and difficulty breathing, and share their travel history with healthcare providers
  • Avoid direct, unprotected contact with live animals and surfaces in contact with animals when visiting live markets in affected areas
  • Avoid eating raw or undercooked animal products and exercise care when handling raw meat, milk or animal organs to avoid cross-contamination with uncooked foods.

Despite a surge in sales of face masks in the aftermath of the outbreak of the coronavirus outbreak, experts are divided over whether they can prevent transmission and infection. There is some evidence to suggest that masks can help prevent hand-to-mouth transmissions, given the large number of times people touch their faces. The consensus appears to be that wearing a mask can limit – but not eliminate – the risks, provided they are used correctly.

The Foreign and Commonwealth Office has advised UK nationals to leave China where possible. It is also warning that travellers from Hong Kong, Japan, Macau, Malaysia, Republic of Korea, Singapore, Taiwan and Thailand who develop symptoms of cough or fever or shortness of breath within 14 days of returning the UK should contact the NHS by phone.

The raising of the alert level came as a Japanese government minister apologised after a woman allowed to leave the coronavirus-hit cruise ship Diamond Princess on Wednesday tested positive for the infection on Saturday, raising more questions about the country’s management of the outbreak.

Warning that China’s virus epidemic was “still grim and complex,” the Chinese president, Xi Jinping, called on Sunday for more efforts to stop the outbreak, revive industry and prevent the disease from disrupting the spring planting of crops. Xi defended the ruling Communist party’s response as “timely and effective” in a video conference with officials in charge of anti-disease work, according to the official Xinhua news agency.

“The current epidemic situation is still grim and complex,” Xinhua cited Xi as saying. “Prevention and control are at the most critical stage.”
