Zhao Guoping: Origin tracing COVID-19 challenging task for scientists
As the COVID-19 pandemic continues to ravage the world, the puzzle of where the virus originated is attracting global attention from the science community.
To identify the origin of an unknown virus, scientists need to find out the pathogen that caused the disease and the animal carrier, that is, the natural host of the virus, according to Dr Zhao Guoping, an academician of the Chinese Academy of Sciences.
Since the outbreak of SARS, global scientists have been searching for its source. They identified SARS-CoV as the pathogen. But it was not until 2015, 13 years after the outbreak, that the natural host of SARS-CoV, Rhinolophus sinicus, was revealed.
Questions are still waiting to be answered including whether Rhinolophus sinicus is the only natural host of SARS-CoV and how the virus varied when it encountered its intermediate host, civet cats.
Tracing the origin of the virus pathogen requires scientific evidence, including the biological evidence provided by etiology, clinical medicine and epidemiology and the molecular biological evidence provided by genetic sequencing and antibody detection, according to Dr Zhao.
Scientists need to establish the connection between the two types of evidence, which is not easy, to confirm both findings before they can finally make the issue clear, he said.
The epidemiological investigation of the origin of an infectious disease usually starts from the contact history of the first infected patient, or “patient zero”, which is even more difficult to confirm.
It is challenging to trace COVID-19 patient zero as it involves a large volume of complicated data, and the early cases might include asymptomatic infections short of medical records, said Liu Peipei, an expert at the Chinese Center for Disease Control and Prevention.
Jin Qi, head of the Institute of Medical Biology at the Chinese Academy of Medical Sciences, said patient zero has not been confirmed for the 1918 influenza pandemic, AIDS or the H1N1 flu that broke out in 2009. Tracing patient zero is a multi-disciplinary problem that requires a great deal of work from the medical and scientific circles.
The novel coronavirus spread extensively around the world since late 2019 and the single “patient zeroes” is absent in most countries, the latest study by the University College London Genetics Institute has shown. -Xinhua
Miniser for Government Communications, Felix Kwakye Ofosu has revealed a major shake up at Ghana Grid Company Limited (GRIDCo) and the Electricity Company of Ghana (ECG) following recent power outages.
In a post on Facebook, Felix Kwakye Ofosu disclosed that Minister for Energy and Green Transition, John Jinapor has asked the CEO of GRIDCo to step aside pending investigations into fire incident at Akosombo power control center.
Also, he further noted that there has been a major shake up in the leadership of the ECG in the Ashanti Region.
“At 2pm tomorrow, Minister for Energy and Green Transition, Hon John Jinapor, will hold a major briefing on recent developments in electricity distribution,” he concluded.

Abu Trica’s extradition case: Prophets, fetish priests demand pay for spiritual solution …Lawyer reveals
Mr Oliver Barker-Vormawor, a lawyer for embattled Frederick Kumi, affectionately called Abu Trica and has made a shocking revelation over the behaviour of some members of the clergy.
According to him in a post on social media, the difficult part of Abu Trica’s trial is not the law but the number of ‘Men of God’ and fetish priests demanding financial sacrifices to help resolve the matter spiritually.
Oliver Barker-Vormawor posted on Tuesday, April 22, 2026, “The most difficult part about the Abu Trica case; is not the law.”
He continued: “It is the number of, prophetesses, evangelists and fetish priests, who have called or messaged to ask us to pay for spiritual solutions.”
It would be recalled that in March this year, the Gbese District Court dismissed a preliminary objection filed by Abu Trica, challenging the extradition proceedings initiated at the request of the United States.
The court, presided over by Anna Akosua Appiah Gottfried Anaafi Gyasi, in its ruling held that the offences forming the basis of the extradition, particularly wire fraud, constitute extraditable offences under the 1931 treaty between Ghana and the United States.
He was then given 15 days counting from March 27 to appeal the decision of the court or be surrendered for extradition to the US.
Against this backdrop, he was on Tuesday, April 22, granted a bail in the sum of GH¢30,000,000 by an Accra High, pending the appeal of his extradition
Mr Kumi was arrested in Ghana in December 2025 following an indictment by United States authorities, alleging that he played a role in a romance scam network that defrauded elderly American victims of more than $8 million.
