Oxegen revellers told to have good, clean fun
Have that antibacterial gel and hankies at the ready.
Festival-goers and music lovers have been warned that infectious diseases are more likely to spread when you're waving your hands in the air and moshing at outdoor concerts.
Professor Aideen Long, Irish representative on the Global Hygiene Council, says messy portable toilets and kebab stands can be a hotbed of infectious diseases.
"The threat is particularly high at these events due to great numbers of people coming together, often eating and drinking from food stalls or mass catering establishments, and using communal toilets," he said.
"The most common infection being gastroenteritis or stomach flu."
Professor Long says to avoid feeling queasy use hand sanitising gel at all times and only drink water from sealed water bottles.
But basic sanitation was far from the minds of punters as they dragged their tents and sleeping bags to Punchestown racecourse for the Oxegen festival last night.
Dance-lovers headed to Kildare early to find the perfect pitch for their tent.
More than 50,000 people are expected to attend the self-acclaimed "greatest festival in Europe". Serbian songstress Rita Ora and her DJ boyfriend Calvin Harris will be enjoying a lovers' break there.
Festival sources have said the couple have decked out their joint dressing room with vodka, Jack Daniel's and a few bottles of Corona.
"They're really going to let their hair down and are determined to make the most of the night," a source said.
