The surge in viruses is the worst seen 'within living memory.'
That's the view of Professor of Health Systems in DCU Anthony Staines, as the country's in the grip of Covid-19, flu and RSV.
The Taoiseach Leo Varadkar met the HSE yesterday asking it to use all available resources immediately to ease pressure on hospitals.
Professor Staines describes why he thinks the viruses have taken hold now:
"Covid does not seem to be seasonal, at least not yet anyway. We're used to getting flu. We got flu every couple of years. Sometimes we have bad flu seasons, sometimes have a better flu season. This is a kind of moderately severe flu season, but by no means the worst we've had; and RSP seems to be going up over recent years for reasons which I don't think anyone really understands. But it's affecting a lot more older people.".
