Researchers identify two coronavirus types as China cases dwindle

  • The study found that one of the strains is more aggressive
  • Around 70% of the analysed strains belong to the more aggressive type

SHANGHAI: Scientists in China studying the coronavirus outbreak said they had found two main types of the disease could be causing infections.
The researchers, from Peking University’s School of Life Sciences and the Institut Pasteur of Shanghai under the Chinese Academy of Sciences, cautioned that their analysis examined a limited range of data, and said follow-up studies of larger data sets are needed to better understand the virus’s evolution.
The preliminary study found that a more aggressive type of the new coronavirus associated with the disease outbreak in Wuhan accounted for about 70% of analyzed strains, while 30% was linked to a less aggressive type.
The prevalence of the more aggressive virus decreased after early January 2020, they said.
“These findings strongly support an urgent need for further immediate, comprehensive studies that combine genomic data, epidemiological data, and chart records of the clinical symptoms of patients with coronavirus disease 2019 (COVID-19),” they wrote.
Their findings were published on Tuesday in the National Science Review, the journal of the Chinese Academy of Sciences.
Also on Wednesday, one of China’s top medical associations confirmed that the median incubation period of the coronavirus is five to seven days and the maximum 14 days.
The remarks by Du Bin, chairman of the critical care medical branch of the Chinese Medical Association, mark the most conclusive assessment of the virus’ incubation period by a government-affiliated medical organization to date.
The revelations came amid a fall in new coronavirus cases following crippling restrictions imposed on the world’s second largest economy to stop its spread, including transport suspensions and the extension of the Lunar New Year holiday.
New cases down
Mainland China had 119 new confirmed cases of coronavirus on Tuesday, the National Health Commission said, down from 125 the previous day, in a broad trend that has seen numbers of new cases fall from the middle of February.
The total number of cases on the mainland has now reached 80,270. The number of deaths rose by 38 to bring the total toll for mainland China to 2,981 by March 3.
All but one new death occurred in Hubei province, where the outbreak started.
With the number of new daily infections overseas now exceeding new cases in China, Chinese officials have begun to seek ways to control the spread of the virus outside of China and guard against future outbreaks.
Authorities have asked overseas Chinese hoping to return home to reconsider their travel plans, while cities across the country have set up quarantine rules for those entering from high-risk places.
An infected person is known to have arrived in China from Iran, one of the virus’ new hotspots, last week.
China is encouraging domestic producers of medical protective equipment to export protective suits to meet overseas demand as the virus spreads, Cao Xuejun, an official with China’s Ministry of Industry and Information Technology said in a press briefing in Beijing on Wednesday.
China’s health authorities are also studying setting up emergency reserves for medical resources and protective materials, Mao Qunan, an official at China’s National Health Commission said at the same briefing.

Mistrial declared in the case of Stanford students charged after pro-Palestinian protests in 2024

SAN FRANCISCO, US: A judge declared a mistrial Friday in the case of five current and former Stanford University students charged after pro-Palestinian protests in 2024, when they barricaded themselves inside the university president and provost executive offices.
The trial in Santa Clara County was a rare instance of demonstrators facing felony charges from protests over the Israel-Hamas war that roiled campuses across the country. The two sides argued over free speech, lawful dissent and crime during the three-week proceedings.
The jury voted 9 to 3 to convict on a felony charge of vandalism and 8 to 4 to convict on a felony charge of conspiracy to trespass. After deliberating for five days, jurors said they could not reach a verdict.
Judge Hanley Chew asked each one if more time deliberating would help break the impasse, and all answered, “No.”
“It appears that this jury is hopelessly deadlocked, and I’m now declaring a mistrial in counts one and two,” Chen said. He then dismissed the jurors.
Demonstrators barricaded themselves inside the offices for several hours on June 5, 2024, the last day of spring classes at the university.
Prosecutors said the defendants spray-painted the building, broke windows and furniture, disabled security cameras and splattered a red liquid described as fake blood on items throughout the offices.
Defense attorneys said the protest was protected speech and there was insufficient evidence of an intent to damage the property. They also said the students wore protective gear and barricaded the offices out of fear of being injured by police and campus security.
If convicted, the defendants would have faced up to three years in prison and been obligated to pay restitution of over $300,000.
Santa Clara County District Attorney Jeff Rosen said he would pursue a new trial.
“This case is about a group of people who destroyed someone else’s property and caused hundreds of thousands of dollars in damage,” Rosen said in a statement. “That is against the law and that is why we will retry the case.”
As the mistrial was announced, the students, some wearing kaffiyehs, sat on a bench in the courtroom and did not show a visible reaction.
“The District Attorney’s Office had Stanford University supporting them and other multibillion-dollar institutions behind them, and even then the district attorney was unable to convict us,” Germán González, who was a sophomore at Stanford when he was arrested, told The Associated Press by phone later. “No matter what happens, we will continue to fight tooth and nail for as long as possible, because at the end of the day, this is for Palestine.”
Authorities initially arrested and charged 12 people in the case, but one pleaded no contest under an agreement that allows some young people to have their cases dismissed and records sealed if they successfully complete probation.
He testified for the prosecution, leading to a grand jury indictment of the others in October of the others. Six of those accepted pretrial plea deals or diversion programs, and the remaining five pleaded not guilty and sought a jury trial.
Protests sprung up on campuses across the country over the Israel-Hamas conflict, with students setting up camps and demanding their universities stop doing business with Israel or companies that support its war efforts against Hamas.
About 3,200 people were arrested in 2024 nationwide. While some colleges ended demonstrations by striking deals with students or simply waited them out, others called in police. Most criminal charges were ultimately dismissed.
