End of coronavirus? ‘Second wave sceptic’ advises how pandemic can be eradicated

One of the most discussed topics during the goverment’s daily briefings is the possibility of a second outbreak of COVID-19 if the prevention measures are disregarded or relaxed too soon. In the UK, it has been debated by critics whether a second wave of cases could be more aggressive than the first outbreak.

Hugh Pennington, emeritus professor of bacteriology at the University of Aberdeen, who calls himself a “second-wave sceptic”, said evidence supporting a second wave outbreak is “very weak”.

He explained: “I said so in evidence to the Scottish Parliament’s health and sport committee in April, and was criticised by Nicola Sturgeon for it.

“I started my virological career working on viruses spread by the respiratory route and was mentored at that time by June Almeida, the discoverer of human coronaviruses.

“I consider that the evidence supporting the notion of a second wave or peak of Covid-19 infections in the UK that would swamp the NHS is very weak.

“If we get the easing of lockdown wrong, far more likely would be a continuation of infections, many in the form of localised outbreaks, but not waves or peaks.”

He then added that theories of a second spike in infections could stem from the 1918 Spanish flu pandemic.

In that year, there was a first outbreak of the disease between June and July, but it was the second wave between October and November that proved deadlier.

However, it is still unclear why the pandemic disappeared after the first wave only to reappear months later.

In 2009 swine flu was far deadlier in its second wave with 137 deaths, than in its first where it killed 10 people.

But Prof Pennington said: “Flu is very different from Covid-19.

“Although both are commonly spread by the respiratory route, and both have infected prime ministers (David Lloyd George got the Spanish flu), the more we learn about Covid-19, the less its biology and epidemiology resemble that of flu.

“There have been no flu-like second waves (or even peaks) in China, South Korea or New Zealand. There was no second wave with Sars, another coronavirus.

“In the absence of controls, flu has an R rate of seven; Covid-19’s is between two and three. And far more than with flu, Covid-19 cases have very commonly occurred in clusters.

“In New Zealand (which may well have eradicated the virus), 41 percent of cases occurred in 16 clusters of 13 or more cases in each. And, sadly, in the UK the virus has taken an enormous toll on residents of care homes, many of which have had multiple cases.”

He adds: “Defeatist flu models still lurk behind current Covid-19 predictions. That the virus will persist for ages is a flu concept.

“These predictions should be put to one side. Like Sars, and unlike flu, the virus is eradicable.

“If China and New Zealand are striving to be free of it, we should be, too.”
