Germany surpass one million infections, S. Korea battles surge in ‘silent’ cases

The figures reflected the reality that Germany was at best keeping new infections stable, which Chancellor Angela Merkel has said would not suffice to ease restrictions and eliminate the risk of overwhelming hospitals.

The number of confirmed coronavirus cases increased by 22,806 to 1,006,394, according to the RKI.

That was 842 fewer new cases than a week ago.

The reported death toll rose by 426 to 15,586, the tally showed. That number was at 260 a week ago, and at 49 on Nov. 2, the day the “lockdown lite” was launched.

Bars, restaurants, theatres and fitness studios are closed but schools and shops remain open. From Dec. 1, private gatherings will be limited to five people from currently 10.

Over Christmas, that number will rise to 10 again in most of the 16 federal states, not counting children under 14, although families are asked to avoid social contact for a week ahead of visits.

The capital Berlin, one of the hardest hit cities in Germany, has said it would not ease restrictions over Christmas.

Germany will probably have to stick with measures to dampen the coronavirus pandemic into January, Merkel said on Thursday, while her chief of staff suggested that restrictions might be needed until March.

Asymptomatic COVID-19 patients are driving a surge in new cases in South Korea, frustrating efforts to control transmission by the Asian country which managed to keep infections under control in previous outbreaks.

South Korea reported 569 new cases in the 24 hours ending Thursday midnight, a level unseen in nearly nine months, as it grapples with the third wave of the pandemic that appears to be worsening despite tough new social distancing measures.

With young people at the centre of the surge, health authorities in South Korea estimate asymptomatic patients now account for 40% of total infections, up sharply from 20-30% in June.

That compares with research evidence suggesting about one in five infected people in general will experience no symptoms.

The rate is much lower in China where the state disease control centre said in February that around 1% of more than 70,000 cases it analysed were asymptomatic. In Tokyo, about 19 percent of patients are asymptomatic.

It’s not clear why some patients who test positive for the virus do not display any symptoms, but health officials believe they pose less transmission risks. However, the people they infect may display symptoms.

Also, the officials are concerned about a rise in untraceable clusters since these asymptomatic infections are more difficult to identify.

Cold weather is further accelerating the spread as more meetings and activities are held indoors in places with poor ventilation, while the risk of unwitting infections by symptomless patients has increased.

That poses a major challenge in South Korea, which succeeded in keeping infections low in previous outbreaks through aggressive contact tracing.

It has introduced tougher social distancing measures this week to contain transmission and encouraged people to get tested.

“We should have maintained tough social distancing measures longer,” said Kim Woo-joo, a professor of Infectious Diseases at Korea University Guro Hospital.

“In the wake of eased social distancing measures in early October, a lot of people, especially young people, let their guard down, and many of those who had very mild symptoms or no symptoms have gone unnoticed.”

As young people drive the surge in new cases, the number of young patients in serious conditions and in need of ventilators has also shot up to 19 this week in South Korea to nearly one fourth of total patients who need ventilator support.

Japan is also battling a rise in asymptomatic cases, as it seeks to rein in its highest surge in infections yet this week, with daily tallies in Tokyo hitting a record 570 as of Thursday.

Public health experts advising the government have warned about a rise in untraceable clusters, spread by asymptomatic patients.

That has skewed the current outbreak, compared with the second wave that hit the country in the summer, more towards older people getting the virus from relatives at home or from infected people at medical facilities, they said.

The rate of asymptomatic cases found in Tokyo was 19% in the week to Nov. 17 compared with about 14% in July, according to a health advisory panel presentation.

Some experts recommend more rigorous testing to protect wider community.
