‘One big wave’ – why the Covid-19 second wave may not exist

‘One big wave’ – why the Covid-19 second wave may not exist

  • With no evidence of seasonal variations, the WHO warns the initial coronavirus pandemic is continuing and accelerating

The Covid-19 pandemic is currently unfolding in “one big wave” with no evidence that it follows seasonal variations common to influenza and other coronaviruses, such as the common cold, the World Health Organization has warned.

Amid continued debates over what constitutes a second wave, a resurgence or seasonal return of the disease, Margaret Harris, a WHO spokesperson, insisted that these discussions are not a helpful way to understand the spread of the disease.

“People are still thinking about seasons. What we all need to get our heads around is this is a new virus and this one is behaving differently,” Harris told a virtual briefing in Geneva, urging vigilance in applying measures to slow transmission that appears to be accelerated by mass gatherings.

She also warned against thinking in terms of virus waves, saying: “It’s going to be one big wave. It’s going to go up and down a bit. The best thing is to flatten it and turn it into just something lapping at your feet.”

The reality is that the issue of second waves has been a contentious one, much talked about by politicians – including Boris Johnson – and the media, but often very ill-defined.
