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
A leading member of the newly rebranded United Party, also known as UP, Hopeson Adorye, has called on Ghanaians who feel dejected or oppressed in politics to join the new party, describing it as a better political home for all.
He made these remarks at the launch and rebranding of the Movement for Change into the United Party (UP) at the Coconut Grove Hotel in Accra on Thursday, October 16.
Mr. Adorye explained that the party was fully ready to serve as an alternative political force to address Ghana’s challenges.
He noted that the UP leadership was focused and determined to change the country’s political structure and bring meaningful transformation.
He stated that the party’s vision was to build a united Ghana, stressing that without unity, the nation could not make real progress.
According to him, the mission of the UP was to create a prosperous country where every citizen could provide for themselves and their families.
Mr. Adorye emphasised that the new party was not formed to destroy any existing political organization but to contest and win elections to bring about the needed change.
He expressed confidence that many Ghanaians from different political backgrounds, including those dissatisfied with their current parties, would join UP+ because of its values and inclusive ideology.
He added that the party was building its structures from the grassroots and hoped to complete them by the end of the year as part of efforts to strengthen its national presence.
The Founder of the United Party (UP), Alan Kwadwo Kyerematen, also addressed the gathering and reflected on the transformation of the Movement for Change into the UP+.
He explained that the rebranding marked a new phase of political renewal, symbolized by the monarch butterfly in the party’s logo, which represents transformation, resilience, and endurance.
Mr. Kyerematen noted that the colors of the party yellow, black, and white stood for Ghana’s gold resources, the black star of Africa, and purity, respectively.
He stated that the UP stands for ethical leadership, integrity, and unity, adding that many of its members entered politics to serve the nation, not for personal gain.
He revealed that the party’s Great Transformational Plan (GTP), which has received global recognition, would guide the UP+ government when elected.
“The plan is designed to stabilize the economy, reduce the national debt, and promote industrial growth through ten strategic anchor industries” he added.
He explained that the health policy would emphasize preventive care, community-based services, and the inclusion of traditional and herbal medicine, which many Ghanaians rely on.
Mr. Kyerematen further stated that the UP would promote a strong Pan African agenda, explaining that Ghana’s prosperity must be tied to the wellbeing of the entire continent.
He noted that the party believes in Ghana first, and its policies were anchored on uniting the country and restoring hope in national development.

Flagbearer hopeful of the New Patriotic Party, Dr. Mahamudu Bawumia, has appealed to the rank and file of the party to rally behind him as he prepares to lead the party in the 2028 elections.
Addressing delegates in Sene East during his campaign tour, he highlighted key contributions to the party.
He revealed that at the behest of former president, Nana Addo Dankwa Akufo-Addo, he left his job at the Bank of Ghana to work for the NPP.
According to him, many asked him to rescind the decision. However, because of his loyalty to the party, he resigned from the bank to be their running mate.
He added that at the African Development Bank, he resigned in 2012 just to serve the party at the highest level.
“I defended the party in 2012. We lost, but I stayed in Ghana to put pressure on John Dramani Mahama and the NDC,” he added.
He is therefore urging the party to choose continuity and to back his leadership.
