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
Dr Theresa Baffour, an advocate for ending violence and Chief Executive Officer (CEO) of SAHM SAHW Foundation, has said that society plays a critical and pivotal role in breaking the cycle of domestic violence.
According to her, domestic violence is a major contributor of making women, who are mostly the victims, mentally derailed and unable to engage in economic activities.
She said this when the foundation called on the Ga Mantse, Nii Tackie Teiko Tsuru II, to solicit support for the initiative by the “Strong and Healthy Minds, Strong and Healthy Women” (SAHM SAHW) to combat domestic violence within the Ga State.
The visit was occasioned by the fact that domestic violence cases have become quite prevalent in the Ga communities and is retarding growth.
According to her, the canker was an impediment to national development because the victims were usually tortured and would have to go through series of therapies to return to the right state of mind.
Dr Baffour mentioned that Gender-Based Violence (GBV) places a mental toll on women, and was, therefore, important to break the cycle through comprehensive mental health support, crisis intervention and empowerment programmes in communities with high rates of GBV.
This intervention, she underscored, would help in empowering the denigrated victim of domestic violence to soundly heal, build and thrive.
Dr Baffour added that the initiative would provide holistic, trauma-informed mental health care and advocacy for young women affected by domestic violence.
According to her, the above statement would create safe spaces for healing and equipping them with entrepreneurial skills for renewed hope and empowered life.
The Ga Mantse pledged his support for the laudable initiative to combat domestic violence and also acknowledged the need to address it in the Ga State.
Further endorsement came from Justice Julia Naa-Yarley Adjei Amoah, Chief of Staff at the Office of the Ga Mantse, as she commended the team of SAHM SAHW Foundation for taking a bold step to end the canker in the Greater Accra.
She added that it was a step in the right direction to save vulnerable women from torture, stress and emotional abuse.

Traders have returned to the streets of Accra, occupying pavements and stretches of some roads after the last major decongestion exercise.
The exercise, which was aimed at restoring order in areas like Kingsway, CMB, Rawlings Park, Tudu etc, have now been defeated.
From Kingsway to Rawlings Park, traders display several wares including, footwear, herbal medicines, plastic products, fresh fish, second-hand clothing, and vegetables, among others.
Local Evangelists are also not left out as they scramble for spaces on the streets.
Pedestrians, therefore, find it difficult to move around when shopping, due to the human and vehicular congestion created by the traders.
In an interview with The Spectator, Auntie Abigail, a trader, said her return to the streets was to sell more, and she saw nothing wrong with it.
Hajia, who deals in wholesale items, indicated that they were unable to make sales as their colleagues move to the pavement and since customers don’t want to come inside, they prefer to buy from them.
Meanwhile, the Chief Executive Officer of Accra Metropolitan Assembly, Michael Kpakpo Allotey, has given traders a grace period to go back to their shops.
