COVID symptoms appear quicker than previously thought - study
Symptoms of COVID-19 appear much more quickly following infection than previously thought, a government-backed study has found.
The landmark Human Challenge Programme, which saw healthy people deliberately infected with coronavirus, found symptoms start to develop very fast, taking just two days on average to appear.
Experts found that coronavirus infection first appears in the throat and then peaks on around day five.
Until now, experts, including from the World Health Organisation (WHO), have widely believed it takes five to six days from when someone is infected with COVID for symptoms to show.
But the new research suggests mild symptoms are apparent even after a few days - even if it takes until five days to become more noticeable.
As part of the study, 36 volunteers aged 18 to 29, who had never had COVID, were deliberately infected with a small dose of the virus via nasal drops.
Just over half became infected.
