My experience of testing positive for coronavirus antibodies clearly struck a nerve. Two weeks ago I wrote that I’d had no recent symptoms but dismissed a bout of pneumonia in January because it was weeks before the first confirmed cases of Covid-19 in the UK.
Many of you responded with your own experiences of having Covid-like symptoms – some as far back as November – and urged me to investigate further.
But is it possible to prove when coronavirus first struck in the UK, and does it matter?
First, a reminder of the timeline.
China reported a cluster of cases on 31 December 2019, but later told the WHO that the earliest symptoms from these patients dated back to 8 December.
But according to unreleased government data obtained by the South China Morning Post (which, I should stress, has not been seen by the BBC) the first case in Wuhan could have been on 17 November, with several further cases that month.
No individual has yet been identified as “patient zero”, the first person to get infected with the new virus.
The first confirmed cases in the UK were identified on 31 January, when two Chinese nationals tested positive in York.
They caught the virus abroad. The first confirmed case of transmission inside the UK was registered in Surrey on 28 February.
But plenty of people are doubting the official timeline.
The author Catherine Mayer believes it’s possible her late husband Andy Gill – guitarist and co-founder of Gang of Four – may have been one of the earliest to be struck down by Covid-19.
She spoke movingly about his death on the Coronavirus Newscast last month.
Andy returned from a tour in China on 23 November 2019 and fell ill in December with many symptoms of Covid-19. He died in St Thomas’s hospital on 1 February. Doctors did consider whether it might be this new virus they were hearing about, but the timelines didn’t seem plausible.
Then a story broke that suggested coronavirus had already been in Europe in December. A hospital near Paris retested old samples from a pneumonia patient which tested positive for coronavirus.
Catherine wrote to Andy’s specialist, who agreed it might have been coronavirus – but how to prove it? She began doing her own detective work and discovered that his tour manager had fallen seriously ill with a respiratory infection too. And, sadly, Catherine’s stepfather also died, on 22 December. “It raises all sorts of questions for me on a personal level,” she says.
“The key question is, could this have been the coronavirus Covid-19?” asks Prof Tom Solomon, director of the UK Emerging Infections Research Unit at the University of Liverpool. “I think the simple answer is yes, it could have been. We now know the virus was around longer – new viruses are always around before you spot them.”
As the BBC’s medical correspondent, since 2004 I have reported on global disease threats such as bird flu, swine flu, Sars and Mers – both coronaviruses – and Ebola. You could say I’ve been waiting much of my career for a global pandemic. And yet when Covid-19 came along, the world was not as ready as it could have been. Now it’s here I wish, like everyone else, it would go away. Sadly, we may have to live with coronavirus indefinitely. In this column I will be reflecting on that new reality.
Read last week’s column: Why do healthy people volunteer to be vaccine guinea pigs?
And many of you have been doing your own investigations. Debra Scott from Blackpool thinks she caught the virus in late November at her husband’s school reunion, where there was “lots of hugging and handshaking”.
Her symptoms included a “cough that could kill a horse” and lasted for weeks. “I kept thinking I was getting better then – boom – it floored me again and again,” she says.
She was so convinced it was Covid that she sent a blood sample off to a lab for an antibody test, which came back positive. She hopes it will give her some immunity, because she’s diabetic. “Before I had the test I was panicking, I didn’t want to end up on a ventilator,” says Debra.
Tricia Camm from Whitby was ill at the end of January, while on holiday in the Scottish lochs. She now thinks it was coronavirus because she lost her sense of taste and kept sending meals back in restaurants. “I was so disappointed, I love the food there,” she says.
But others are more sceptical. David Brown, a retired molecular virologist worked on coronaviruses for 20 years.
His wife got pneumonia over Christmas, with an appalling cough and loss of taste and smell.
He thinks she and many others probably had another coronavirus, OC43, which can also cause respiratory illnesses.
“OC43 can be really severe. It can cause recurring infections in your lifetime like other coronaviruses. There’s no surveillance of it, and it’s impossible to go back and check,” he says.
