China could see over 6.30 lakh Covid cases daily, warns study

Published

“The estimates revealed the real possibility of a colossal outbreak which would almost certainly put an unbearable burden on the medical system,” the report said.

The country on Saturday reported 23 new COVID-19 cases, including 20 imported ones as the country appears to have contained a recent spike of infections in Beijing and other cities.

According to a report by the Peking University mathematicians, China could face more than 630,000 coronavirus infections a day if it dropped its zero-tolerance approach and followed other countries by lifting travel bans.

China, where the coronavirus first surfaced in Wuhan in late 2019 before it turned into a pandemic, has so far reported 98,631 cases and 4,636 deaths, the National Health Commission said on Sunday.

This included 785 patients still receiving treatment.

On Saturday, Chinese top respiratory expert Zhong Nanshan warned that the new and more contagious coronavirus variant Omicron, reported in South Africa causing global alarm, may cause more challenges to the work of preventing and controlling the pandemic as the World Health Organization (WHO) said it carries a large number of mutations.

He said that about 76.8 per cent of China’s population have been vaccinated, laying a good basis for the country to reach the target of 80 per cent vaccination to build herd immunity by year end.

One of China’s major vaccine producers, Sinovac Biotech, told state-run Global Times that the company is paying close attention to Omicron and have tapped into a global partner network to collect and obtain information and samples specific to the mutant virus.

As the outbreak turned into a pandemic, China shut itself mostly with flight bans to most of the countries, including India, and did not permit thousands of foreign students, including 23,000 from India, studying in Chinese universities despite scathing criticism.

Earlier China had no option but to aim for zero infections because the coronavirus was replicating quickly and the global death rate of about 2 per cent was unacceptable, Zhong told state-run CGTN-TV.

In a report published in China CDC Weekly by the Chinese Centre for Disease Control and Prevention, the four mathematicians from Peking University argued that China was not ready and could not afford to lift entry-exit quarantine measures without more efficient vaccinations or specific treatment.

Currently, people arriving from abroad have to undergo 21-day quarantine in designated hotels.

Using data for August from the US, Britain, Israel, Spain and France, the mathematicians looked at the potential results if China adopted similar pandemic response strategies to those used in the selected countries.

In August, most of these countries had presented higher vaccination rates than China, where 54 per cent of the eligible population were inoculated.

These countries also had a higher natural immunity ratio, despite having lower population densities than China.

The researchers estimated that China would have more than 637,155 daily confirmed cases if it went down the same pandemic strategy path as the US, which had an average of 150,098 daily cases towards the end of August.

The report said China would have had 275,793 cases if it took the same approach as Britain and 454,198 cases if it followed France.

“Our findings have raised a clear warning that, for the time being, we are not ready to embrace ‘opening-up strategies and rely solely on the hypothesis of herd immunity induced by vaccination advocated by certain Western countries,” Hong Kong-based South China Morning Post quoted the report.

However, the study did acknowledge the estimates were based on basic arithmetic calculations and that more sophisticated dynamic models were needed to study the evolution of the pandemic if travel restrictions were lifted.

The researchers said that China would need a range of preparations in place – including more efficient vaccination coverage and specific treatment, different levels of non-pharmaceutical interventions and more hospital beds – before it could safely transition to opening-up strategies.

What We Know About the New COVID-19 Variant, Omicron

Published

on

Johannesburg/London: Authorities around the world have reacted with alarm to a new coronavirus variant detected in South Africa.

Britain, the European Union and India are among those announcing stricter border controls as scientists carry out tests to determine if the mutation is more transmissible or infectious than other variants, or is resistant to vaccines.

South African scientists detected a small number of the variant known as B.1.1.529 on Tuesday in samples taken from November 14 to November 16.

The country has identified about 100 cases of the variant, mostly from its most populated province, Gauteng, where Johannesburg and Pretoria are located.

Why is it worrying scientists?

All viruses – including SARS-CoV-2, the virus that causes COVID-19 – change over time. Most changes have little or no impact on their properties.

However, some changes may affect how easily they spread, their severity, or the performance of vaccines against them.

“This variant has drawn particular scrutiny because it has more than 30 mutations of the spike protein that viruses use to get into human cells,” UK health officials say.

That’s about double the number of the Delta variant and makes it substantially different from the original coronavirus that current COVID vaccines were designed to counteract.

South African scientists say some of the mutations are associated with resistance to neutralising antibodies and enhanced transmissibility, but others were not well understood, so its full significance is not yet clear.

UK Health Security Agency Chief Medical Advisor Susan Hopkins told BBC radio that some mutations had not been seen before so it was not known how they would interact with other ones, making it the most complex variant seen to date.

So more tests will be needed to confirm if it’s more transmissible, infectious or can evade vaccines.

The work will take a few weeks, the WHO’s technical lead on COVID-19, Maria van Kerkhove, said on Thursday. In the meantime, vaccines remain a critical tool to contain the virus.

No unusual symptoms have been reported following infection with the B.1.1.529 variant and, as with other variants, some individuals are asymptomatic, South Africa’s National Institute for Communicable Diseases (NICD) said.

Where else has the variant been detected? 

South African scientists say early signs from diagnostic laboratories suggest it has spread rapidly in Gauteng and may already be present in the country’s other eight provinces.

South Africa’s daily infections nearly doubled on Thursday to 2,465. The NICD did not attribute the resurgence to the new variant, though local scientists suspect it is the cause.

Neighbouring Botswana said it had detected four cases, all foreigners who arrived on a diplomatic mission and have since left the country.

Hong Kong has one case, a traveller from South Africa, Israel also has one, a traveller returning from Malawi in southern Africa, while Belgium has detected Europe’s first case.

Scientists say early detection due to genomic surveillance in Botswana and South Africa may have limited the spread of the variant.

The international GISAID open database of coronavirus variants has 58 cases of B.1.1.529 registered in South Africa, six in Botswana and two in Hong Kong.

The variant is relatively easy to distinguish in PCR tests from the Delta variant, the dominant and most infectious COVID-19 mutation so far. Unlike the Delta variant, it has a mutation known as the S-gene drop-out.

However, this is not a unique identifier because the Alpha variant, first identified in Britain, also has that mutation.

How does the World Health Organization label variants?

The UN agency said on Friday its advisers recommended that the variant be designated one of concern, its most serious level, and it has been given the Greek name Omicron.

The latter label is applied if there is evidence that it is more contagious or more virulent or vaccines work less well against it, or has a combination of those characteristics, and it is given a Greek name, the WHO’s website says.

The WHO has identified four other variants of concern – Alpha, Beta, Gamma and Delta.

It has named two variants as ones of interest, which is the next level down: Lambda, identified in Peru in December 2020, and Mu, in Colombia in January.

That means they had genetic changes that are predicted or known to affect virus characteristics such as transmissibility, disease severity or the ability to evade vaccines and drugs.

It would also mean it caused significant community transmission or multiple COVID-19 clusters in multiple countries with increasing relative prevalence alongside increasing number of cases over time and is an emerging risk to public health.
