LONDON: Infection with flu and coronavirus at the same time more than doubles a person’s risk of dying than if he or she only had COVID-19, according to research released by England’s highest public health body.
Research conducted by Public Health England (PHE) found that those with flu and COVID-19 were 2.27 times more likely to die than those who just had COVID-19, and 5.92 times more likely to die than those who had neither.
Researchers found that those aged 65 and over were at greatest risk. Most cases of co-infection were in older people, and more than half of them died.
The paper describes the possible impact of COVID-19 alongside seasonal flu as a “major concern.”
Yvonne Doyle, medical director of PHE, said: “If you get both you’re in some serious trouble, and the people who are most likely to get both of these infections may be the very people who can least afford to in terms of their own immune system, or their risk for serious outcomes.”
The paper found that people with flu were less likely to test positive for COVID-19, but Doyle said this should not be taken as a reassurance.
Some countries in Asia have pre-emptively rolled out early and more aggressive flu vaccination programs this year to prevent complications caused by co-infection.
But others, such as Poland, have been struggling to secure flu vaccines due to shortages caused by the coronavirus pandemic.
The upcoming flu season has been identified by the World Health Organization (WHO) as a particularly acute threat, given that many parts of the world are already experiencing a spike in COVID-19 infections.
“We’re starting to see worrying trends in some countries,” said Maria Van Kerkhove, WHO technical lead for COVID-19. “We’re seeing increases in hospitalizations, in intensive care units … That’s worrying because we haven’t seen the flu season yet.”
