Not a single case of influenza has been detected by public health officials in England for the past seven weeks, with infection rates at historic lows amid the ongoing Covid-19 restrictions.
The social restrictions brought in to curb transmission of coronavirus, combined with increased uptake of the flu vaccine, have both been credited with driving down infections.
Thousands of swab samples are processed and analysed by scientists at Public Health England (PHE) every week to survey the prevalence of different respiratory diseases in the population.
But of the 685,243 samples that have been reviewed at PHE’s laboratories since the first week of January, not a single one has tested positive for influenza. In the week up to 31 December 2020, just one case of flu was confirmed by laboratory analysis.
